The Digital Man: Sherlock (2010) Part 1

Posted on 03:58 by Unknown
Category: Techtoday

Note: SPOILERS abound - please proceed at your own risk.
All screen captures from Sherlock (2010) DVD

I was teaching technical support to a class back in 2006 and I asked my trainees if any of them had ever read a Sherlock Holmes story. Sadly, none of them did (though I'm pretty sure they came out in droves when Robert Downey Jr. appeared in Guy Ritchie's rendition of the London detective). With Benedict Cumberbatch's 6-episode turn as the immortal sleuth, no one has an acceptable reason for skipping Holmes' adventures especially since this sexier and less amiable version is clearly living in the digital age.

It's a very realistic depiction of how an intelligent man with average (by today's standards) technical abilities uses computers and devices efficiently. Unlike most people, who use sites such as Google and Wikipedia as a crutch to reason, defend, make decisions, or just promote themselves, Sherlock uses them as tools - as computers and the Internet were designed to be. Moreover, unlike the CSI shows, which overstates and overuses (and according to experts inaccurately) depicts the use of technology, Sherlock's use of the Internet and smartphones is firmly grounded and emphasizes intelligence rather than dependency. In fact, episodes which depict Holmes using a basic electron microscope and software to analyze chemical content may be pedestrian but it's actual lab software.



1. He uses them to communicate. Text messaging occurs often in the episodes. Holmes instructs Watson (who is exceptionally played by The Hobbit's Martin Freeman) to make phone calls (to Lestrade, the police, or Mycroft).

2. He checks the weather (as shown in the episode Study in Pink), images of the city and the high tide/low tide (The Great Game),  and checks news bulletins and popular sites.

3. The maps on his smartphone only supplement his already comprehensive knowledge of London's labyrinthian alleyways (I've actually seen people take out their smartphones just to navigate their own street).

4. Holmes uses search on laptops and phones to confirm, review, and reference his ideas and opinions, conjectures, and conclusions. Meanwhile, in the real world, a German politician plagiarized his dissertation, as did an Australian's doctorate thesis, just this year. People online pass off their work as their own and pretend to know stuff they really don't (like this Russian who Googles everything just to prove he's "technical"). Even news journalists and writers quote Wikipedia, not even bothering to do additional research. Holmes uses his own skills to confirm what other resources assume is false or even true. In a climactic scene in the episode The Great Game, Sherlock quickly searches online using his smartphone to confirm that it was the astronomical inaccuracy of a painting that proves it is an imitation.



5. Holmes uses his phone's camera to take quick snapshots of evidence or events. Now, in most cases, I'm against using mobile devices for taking photos (there's nothing more laughable than some tourist using his iPad to take a photo of his friend standing in front of the Shanghai skyline). However, Holmes uses his mobile phone for taking photos as reference, not for trivial and pedestrian reasons like printing it out or posting them on Twitter. Photography "enthusiasts" spend oodles of money on DSLRs and accessories with no idea how to use the features - they don't even bother to read the manual and take shoddy useless photos. Holmes uses what he needs, no more and no less. 

6. Unlike users who believe their phone and choice of platform defines who they are and what they do (Mac vs. Windows, iOS vs. Android), Holmes is largely more utilitarian. He's not chained to his own devices and even uses other people's phones and Watson's laptop (much to his friend's indignation). 

7. As seen in the first season, he has a simple web site that discusses his methods, which may indicate either basic knowledge of web development or use of preconfigured blogs/web sites like Wordpress.com or Blogger.com. In the third set of episodes, Sherlock is shown using a Macbook though there are two scenes where his or Watson's laptop is an unmarked Samsung or Dell running Windows 7 (both identifiable by the design of the lid and the Windows orb).




8. Watson learns that Holmes hardly gets paid for his efficient services. That and the fact that Holmes is clearly not using the latest Samsung, Apple, or Sony hardware proves that Holmes uses what device he has on hand. But what phone or laptop Holmes does have, he uses to best effect. Most people with disposable income, on the other hand, buy, trade, and toss aside devices incessantly, boasting about their new product in forums and complaining vigorously about everything from the weight, screen size, and included apps.

Testing hardware compatibility with Knoppix featuring the ASUS U80A

Posted on 01:14 by Unknown
Category: Linux

As a Linux user, I'm always on the lookout for sturdy laptops that can be "recycled" by installing a Linux distribution on them. Considering how wasteful some users are when it comes to their electronics, and with laptops being tossed aside for ultrabooks and tablets, now is the best time to find old laptops for use for students and kids who can't afford a laptop but want to learn Linux, computers, and networking. People with disposable income and the privileged can be extremely cruel to their old laptops and netbooks, treating them haughtily and with disdain after the machine's years of service.

I pounced on an old ASUS U80A that an acquaintance was going to dispose of after deciding he "needed" a Macbook Pro. The U80A was old but serviceable with a competent T5900 2.20 GHz Core 2 Duo processor and 4GB of RAM. In fact, it was a bit too powerful to be demoted from a business machine to a student's laptop, but I could definitely see a young student using the system for learning programming, graphic design, and Linux.




The laptop was sold a good 4 years ago but with a little bit of work can be revived to become a fairly powerful machine. My first stop was testing for Linux compatibility and booted via LiveUSB into Knoppix 6.5, which is several releases behind the current Knoppix (which is at 7.x). However, the Debian-based distribution is so dependable as a LiveUSB, I've never really upgraded, Moreover, Debian's well-known hardware support is what I need for testing "old" hardware like the U80A.








Knoppix booted up perfectly and supported all the necessary hardware including:

1. Atheros Ethernet Controller
2. Intel Wifi Link 5100
3. Maximum display resolution of 1366 x 768
4. Webcam
5. Bluetooth

Taipei's Taoyuan Aiport is Wi-Fi Linux friendly!

Posted on 00:39 by Unknown
Category: Linux

It may seem odd to note that a specific place or country's Wi-Fi is Linux friendly, but I've had issues connecting to some public Wi-Fi services in other countries using my Linux machines. In Kuala Lumpur International (KLIA) for instance, I had to visit the KDE Terminal to manually connect to the main login page for the free wireless service. In most cases, you should be able to connect without having to manually setup iwconfig with KDE's Network Manager just working on the sport. Most public Wi-Fi, however, is tested for iOS, Android, Windows, and MacOSX but not Linux so I take note of places where accessing the wireless signal can be troublesome or may require additional steps for the Linux user. Take note, however, the hardware (in this case my Toshiba NB520) and your Linux distribution (in this scenario openSUSE 12.2) takes a hand in how easily you can connect and how good your performance is.








The Taoyuan Airport Terminal 2 free wireless service is set up very well and the speed was fast enough for me watch YouTube videos as I browsed Flipboard on my iPad. Once I was past immigration and into the airport gates, I tried connecting to the same free airport Wi-Fi signal but failed using my Toshiba NB520 with openSUSE 12.2. I figured out if was more likely because the Wi-Fi extender for the airport gates were positioned farther apart and prevented me from getting a good signal (my gate was at the farthest end of the airport) However, I was able to access the unsecure Huan Yu VIP Terminal Wi-Fi signal using openSUSE KDE without issues. The performance, as could be expected, was excellent. I should be ashamed to be taking advantage of the VIP Wi-Fi services but I was a scant two hours away from my flight anyway!

BBC News and Flipboard App for iOS

Posted on 04:57 by Unknown

Category: Tech Today

I'm not an App whore. I get hives if I go past three pages worth of apps on my iPod Touch (Yeah, yeah even that Japanese guy next to me on my flight was wondering why I didn't have an iPhone yet). I'm happy with my 6 free dictionaries, 2 document readers, video player, Opera browser, and the occasional map and city guide when I go on a business trip. Besides, I'm perfectly happy accessing news and doing serious work on my Linux portables. However, on a business trip to Taipei, I took advantage of the free wireless all over the city and at the company and installed BBC News and Flipboard and I must say I was thoroughly impressed.



The BBC News app is an example of excellent design with easy to navigate articles, scalable videos, and well-written HTML5 code. It was just a great experience overall even on my 2nd generation iPod Touch. The images rendered fast and videos streamed well even on a messy LAN setup. Now, most readers are probably thinking it's because of the Apple iPod's performance, but part of any app's experience is due to how well developers optimize the content for small screens and approach preprocessed data. The BBC News app deserves the praise it gets from PCWorld and PCMag. After just a few days of using the app, I came to the conclusion the BBC News app is another reason why I'm such a huge fan of BBC's offerings (BBC's exceptional podcasts and 2010's Sherlock being two other compelling reasons). I know it's a conflict of interest but I'd love to see Benedict Cumberbatch's Holmes browsing the BBC app in the next season of Sherlock.



Flipboard is a more mainstream and more well-known app, particularly in the U.S. As an old school Internet user who was baptized with IE5.0 and Netscape Navigator, I have to admit it took me a few tries to get used to Flipboard's lateral and horizontal navigation - it was quite different from the BBC News app. Flipboard, however, is also exceptionally well-designed and provides a wider breadth of news sources. I can definitely imagine Holmes flipping up and down the many pages of Flipboard, going through news articles to entertainment and remembering everything he reads. Sherlock would probably use Flipboard to browse through everything from Apple's falling stock, the newest politician accused of stealing pork, to the latest Zac Efron movie. Like the BBC News app, Flipboard focuses on the text and the images on the iPod touch version. I've read reviews praising its beautiful design on the iPad, but I feel that finding a well-optimized app for the smaller iPod is more difficult to find than finding one for the luxurious real estate of the iPad.


"Hmmm. Based on this photo in Flipboard, my powers of deduction tell me that Kardashian's left boob is 17 degrees higher than her right." Screenshot from season 1, episode 3 of Sherlock (2010).

I prefer consuming media and news on the go via audio podcasts. After all, how will you enjoy the scenery, the weather, or the leggy young lady who looks like Sowelu if you're too busy with the numerous apps on your device? If I really want to browse online in public, I'd probably scrounge up enough money to buy a cup of java in a coffee shop and boot up to openSUSE or Lubuntu on my laptop. However, I do understand the attraction of having easily accessible mobile content anywhere you go. Today's generation of Internet users is extremely lucky and I envy them for having the attention span and skill to consume so much of the world in so little time. As for me, I'll pretend to be Sherlock Holmes in public, minding everything else but my mobile devices, and occasionally accessing Flipboard and BBC News for reference.

Cannot export to PDF using Adobe InDesign (MacOSX) Part 2

Posted on 04:34 by Unknown

Category: Techwriter

Continued from Cannot export to PDF using Adobe InDesign (MacOSX) Part 2

InDesign crashing midway through exporting to PDF

Even without the "Out of memory" error message, a failed exporting process could also be caused by memory issues. There are other reasons why this occurs, however, such as the following:

1. A corrupted JPEG file - Personally, I would never use JPEG with InDesign. The quality is bad enough even before you compress the image a second time to PDF. Use TIFF, a vector format like SVG or EPS, Photoshop's native file format, or even PNG rather than a JPEG file. If you don't have the luxury of using the other file formats, than convert the JPEG to a more usable file format using Photoshop (though this is a last resort). JPEGs, to its credit, is a fairly resilient file format despite its poor quality and even a corrupted JPEG file can be made usable if processed using the right software (I've had luck with Corel Photo-Paint and Linux's ImageMagick and Gimp).



2. A damaged or older EPS file - EPS is a great format and InDesign will often handle EPS very well. However, Adobe products may find EPS files produced using legacy applications as unpalatable. A quick test is to open the EPS file using a Linux application such as Inkscape or a non-Adobe application such as CorelDraw. If the EPS can be exported to PDF using any of the other applications, then you may need to re-save the EPS file using Adobe Illustrator.



InDesign may sometimes detect unfriendly EPS files during the export process and pop up with a message. Sometimes, InDesign will just crash or halt.

3. Mismatched color profiles - Colour profiles are the last thing a technical writer thinks about but one of the more important aspects that concerns a designer or artist. If you're moving work between Windows and Mac or you get your artwork from someone else, placing them in an InDesign layout and attempting to export the document to PDF may cause InDesign to crash. You can actually ignore color warnings by InDesign if color isn't an important element in the PDF output. However, if you can't produce a PDF due to color issues, you can prevent InDesign from converting the colour during PDF export. In the Export Adobe PDF window, click Output on the left panel. On the Colour Conversion item, select "No Colour Conversion."



Tracking down the Culprit


To find out what nasty file is causing Adobe InDesign's PDF engine to crash or prevent the PDF from being produced, you have to sit and watch the progress window as the PDF is being produced.

As InDesign exports your InDesign file to PDF, it will list the files one by one. Watch the files carefully. The progress and message will pause on larger AI, TIFF, or vector files as it goes through the Book or InDesign pages. When InDesign crashes, take note of when it crashed - if it occurred on an EPS or AI file then you know which file to troubleshoot as well as the page where the image is located.



As a final note, always use the Adobe dialog boxes when managing your Adobe file. Never use OSX's dialog box. It makes troubleshooting Adobe products much easier.

Cannot export to PDF using Adobe InDesign (MacOSX) Part 1

Posted on 04:32 by Unknown

Category: Techwriter

If you're saddled with an OSX workstation, whether it's a Mac Pro with a Dual-Core Intel Xeon 2.66 GHz processor or one of the sexier new Macs Apple released recently, an earlier version of Adobe InDesign may experience issues exporting to PDF. The common symptoms are:

1. InDesign shutting down midway through exporting to PDF
2. An unusable 0KB PDF
3. An "Out of memory" error message
4. InDesign displaying an error message regarding an EPS or color profile



This issue is commonly caused by the following:

1. A poorly maintained MacOSX system
2. Conflicting Adobe libraries (such as when more than one version of an Adobe application is installed)
3. Memory management or RAM issues (which contrary to Apple cult members occurs more often than you might think)
4. EPS or JPEG image

The newer versions of MacOSX require less maintenance than the older releases especially in relation to workstations installed with Adobe products. However, a MacOSX system that hasn't seen much updates can be as difficult to work with as an aging Windows XP system.



Having more than one Adobe version (e.g. CS2 and CS4) of a product is occasionally unavoidable for some companies but it is not recommended. In general, it's a better idea to have a different Mac or even a Windows system devoted to an earlier version than to have two generations installed on the same Mac machine. Surprisingly, Windows handles two versions of an Adobe product better than OSX.

Out of Memory


The "Out of Memory" message that occurs when you are exporting a PDF in Adobe InDesign can be caused by a hugely complex vector image, InDesign file, or photograph that your MacOSX machine cannot handle. This isn't to say your Apple machine lacks memory to run InDesign properly. It's more of Adobe + Mac's ability to work together. Some of the steps you can do to work around this issue are:

1. Close out your applications and use the memory clear command from the Terminal. Unfortunately, if you're running a really old version of OSX or you're running a system with less than 2GB of RAM, these steps will hardly help in resolving this InDesign issue.

2. Reboot your system. This well-known Windows troubleshooting step may seem sacrilegious to the Mac faithful but it does temporarily resolve the "Out of memory" error message in InDesign. In most cases, it is enough to produce a usable PDF.



3. Avoid using images or vector illustrations created in a more recent Adobe product and then importing or using them on your earlier InDesign application. For example, if you were provided an illustration designed in Illustrator CS4 and you used the Place command to add it to your Adobe InDesign CS2 document, it may seem like the EPS or .AI file was imported properly. However, the PDF engine of InDesign may struggle to export the document with this image causing InDesign to shut down, produce a 0KB PDF file, or just display the "Out of memory" message. In this case, it's not the size of the image, illustration, or .INDD file that matters but rather the type of objects you import. Even legacy-friendly formats such as EPS and TIFF can cause issues for an old InDesign version if it was produced from newer software.

Review: Toshiba NB520 netbook featuring openSUSE 12.2 Part 2

Posted on 03:12 by Unknown
Continued from Review: Toshiba NB520 netbook featuring openSUSE 12.2 Part 1

Category: openSUSE

Startup and shutdown speed

I'm not a huge fan of benchmarks since individual user configuration plays a lot in how a system boots up especially when you're running a system as malleable as Linux.

The first step users might want to be is do head off to the BIOS and switch to the Advanced tab. Select Fast from the options.  Changing that setting doesn't improve boot performance but it does remove the Toshiba logo that appears seconds after you press the power button. It's more of a psychological effect than anything else (it shaves off a second or two).  One of the disadvantages of using this setting, however, is it makes entering the BIOS again a tad difficult (just hold down the F2 button after you press the power button if you find boot up "too fast" to get to the BIOS).


If you configured Grub2 to the lowest timeout value (or you have a fast trigger finger), boot up speed of openSUSE 12.2 KDE is a respectable 1:01.6. It's not exactly Archlinux or even Lubuntu fast but if you're committed to openSUSE, it's actually an improvement over previous releases (particularly compared to the 11.x series). Moreover, the latest release of openSUSE KDE 12.3 is purported to be much, much faster

As usual, openSUSE 12.2 actually loads a working desktop first before the audio kicks in - not unusual for openSUSE. There are plenty of services you can disable using the System Settings window, but the settings that are directly  relevant to performance and boot up speed are the desktop effects (which can be disabled by unchecking one box) and Nepomuk. In other openSUSE boxes, I generally also disable any Bluetooth services since I don't have much Bluetooth accessories but the Toshiba's performance is such a leap from my previous machines that having the service enabled doesn't really do much to impact the system.



Shutdown with openSUSE 12.2 is a disappointing 18.6 seconds in my informal tests. It's not a deal breaker but it's certainly much longer than my Lubuntu and on par with Windows 7. Take note, however, that comparing openSUSE with frugal Linux distributions like Archlinux and Knoppix is unfair considering that a default openSUSE install comes loaded with several server technologies and virtualization tools.


Yast2 and KDE Performance on the NB520


KDE lags behind LXDE, Xfce, and even Enlightenment17 in terms of optimizing desktop objects. However, a well-maintained and adequately equipped system makes any KDE performance issues a moot point. In fact, the Toshiba NB520 handles all aspects of the desktop perfectly even when desktop effects are enabled or a few KDE Activities/widgets are running. Of course, filling up your desktop with widgets isn't exactly going to help your productivity especially with the 1024x600 resolution of the Toshiba NB520.

KDE's desktop and Mozilla Firefox are two of the slower aspects of openSUSE's default configuration but working with this netbook in the last few months has been a pleasure to say the least. I actually loaded LXDE as an alternative desktop environment but ended up using KDE instead - openSUSE has always worked better with KDE and KDE's bloat hardly affected the NB520's performance. I converted ebooks with Calibre, managed comic books and files on Dolphin, copied photos from the SD card, surfed the web, watched YouTube, ran Transmission for torrents, wrote blog posts, watched and exchanged e-mails with Thunderbird with nary a burp.  I watched a ripped video of MTV's Spider-Man (which by the way was equal parts awesome and horrible) and enjoyed Neil Patrick Harris' voice acting via the Toshiba NB520's Harman Kardon speakers (despite Brian Michael Bendis' terrible writing, the visuals and audio production of MTV Spider-Man was actually good).



System Activity with Cherrytree, Transmission, and SMPlayer is extremely respectable though I don't really multitask much when I'm running a netbook - which actually means I get more work done than on my Ideapad.

One of the more visible effects of the newer Atom processor and 4GB of RAM on a netbook is launching YaST2. openSUSE's comprehensive systems manager used to launch slowly on my old Pentium M Acer Aspire 5500Z and my older EEEPC1000H. It didn't take forever on those older machines but with quadcore processors, tablets, smartphones, and increasingly shorter attention span of today's generation of users, the experience could be off-putting. However, launching YaST on the Toshiba NB520 was close to instantaneous. Even launching YaST2 tasks that require scanning hardware, such as Network Settings, Partitioner, Hardware Information, and Sound management, took less than 30 seconds.



Although I never timed openSUSE's YaST2 performance when I had it installed on my Lenovo Ideapad Z360, openSUSE feels faster on the Toshiba NB520 than on the i3 powered Lenovo notebook.

Harman Kardon and HD video


One of the selling points of the Toshiba NB520 is the Harman Kardon speakers on the palmrest. It's not a gimmick - the speakers are clearly superior to the tinny speakers on both my Ideapad Z360 and ASUS EEEPC 1000H regardless if the video or music file is encoded poorly. The design certainly doesn't replace the sound system of desktop replacement laptops but it does give an oomph - enough to annoy passengers on an airplane or airport waiting area if you decide to skip the headphones. The KDE boot up sound of openSUSE certainly made me blush when it tinkled in Shanghai's boarding area while waiting for my flight.

The newer integrated Intel HD chipset on the Toshiba NB520 could handle professionally encoded streaming video, such as those found in the Apple iTunes trailer web site. I also tried playing a downloaded Flash Gordon (1980) movie using SMPlayer and VLC. The result was a mixed bag. Audio was fine and came out clear on the aforementioned Harman Kardon speakers. Unfortunately, you couldn't scrub through the movie without ruining playback - the Atom processor and Intel chipset had problems playing, rendering, and fast-forwarding the HD video at the same time. You can play the movie from start to finish but I certainly don't recommend attempting to skip to the good parts (I tried to skip to the part where Ornella Muti was attempting to seduce Flash).

Ok, so the Toshiba NB520 peaks at an odd 1024 x 600 resolution. But if you wanted an expensive hybrid laptop, ultraportable, or tablet, you would've shelled out extra cash for one right? As it is, I'm extremely comfortable with the display especially once I got used to the keyboard (which in my quick review I struggled with initially after years with the 1000H). It would be embarrassing to review the colors and screen quality in light of today's incredibly amazing and superfluous displays (e.g. Retina screens). Besides, I'm not a gamer and I don't try typing or watching Sherlock (2010) on my netbook from a 15 degree or 45 degree angle. The brightness keys didn't work but there's probably a fix for resolving this though it didn't really matter since the battery is exceptional even if I didn't lower the screen brightness.

Wireless, Bluetooth, and Windows 7

Wireless and bluetooth worked out of the box. I've already written about openSUSE's 12.2's improvements with the KDE Network module and found no issues connecting to wireless networks. It also helps that the FN keys for the wireless works. The Atheros Bluetooth, on the other hand, can also manually be switched on using the notification tray icon (no more rfkill!). I've only recently discovered the usefulness of Bluetooth and I have to admit having a Bluetooth system working on Linux is convenient.



The Intel Atom N2800 is several generations ahead from the first Atom processor I tried years ago and performs quite admirably compared to the processor on my first generation EEEPC 1000H. Intel's Atom processor frequently gets overshadowed by news about the Nvidia Tegra and Qualcomm processors in tablets, but I can't imagine having anything else on this NB520 netbook. Plus, having the 4GB of RAM on a netbook added an additional cushion to somewhat heavier desktops tasks like multi-tasking online or converting audio. 

Toshiba bundles some fairly compelling applications such as Sleep N' Charge and a few interesting FN keys. Unfortunately, they are designed only for Windows. FreeBSD and Linux users are left out of the party but there are reasons to just forget about the utilities - if you upgrade the laptop's RAM to 4GB then you can't dual-boot to Windows. Windows just won't boot with 4GB installed. So you're left with the choice of using a powerful Linux system or settling for an anemic Windows 7 Starter/Windows 7 with 2GB of RAM.



I agree that Intel should move on from Intel Atom processors but I'm glad I bought the Toshiba NB520 while I had the chance. I encourage penny-wise and no-nonsense tech workers to get one before they're gone.I don't recommend the NB520 for Windows users because of obvious reasons - RAM maxes out at 2GB with Windows 7 due to Microsoft's hardware limitations. However, I popped in 4GB and openSUSE ran with the ball and made everything work. The NB520 is a steal if you're a Linux user. And openSUSE?  If you haven't tried openSUSE, download 12.3 now - 12.2 is excellent on my netbook and 12.3 is even better.

Bringing Your Digital Portfolio to an Interview Part 2

Posted on 05:46 by Unknown

Continued from Bringing Your Digital Portfolio to an Interview Part 1

3. Portable storage - So the interview is being held in a room without wireless access and you weren't allowed to bring in your Macbook Pro or your Google Nexus by the security guard who looks like he can arm wrestle Captain America. No sweat. Don't lug around your Seagate External Drive or Thunderbolt server just to show off your offline work (Due to security reasons, IT companies won't let it past their entrance anyway). Instead, bring a virus-free SD card or USB flash drive. I don't have to emphasis that your media needs to be formatted using FAT32 or else your interviewer's OSX or Windows might have problems accessing it. It may seem primitive bringing along an SD card or USB stick in this day or age but it's a great backup plan in case there's no other way to show off your work. Take note of file formats. Don't expect the interviewer to have the correct codec, Adobe software, or Flash version to run your document, program, or movie. Play it safe especially if you're applying for a job that involves proprietary Adobe formats.



Even if the interviewer doesn't pop in the SD card or browse through your flash drive, you've shown initiative and forward thinking by bringing storage along. It's better than saying "Hey, I can Bluetooth the files to you. . ." Final note: ask for the portable media back once the interview is over. They can easily forget about it and you'll end up losing your precious data.

4. DVDRW - Ok, so a lot of hardware have done away with disc drives and everyone views DVDRW or CDRW burners and discs as relics of the Middle Ages. However, like the SD card and USB flash drive, it's a great way to show that you came prepared to demonstrate or show your portfolio. Unlike the aforementioned portable storage, however, make sure that you're ready to lose the files you burn on to the disc. The HR guy expects that you're giving it to him for perusal. Later on, when he's ruffling through his list of interviewed applicants, it's a reminder of your incredible foresight. You don't have to create an autorun script (in fact, I don't recommend it) or even create an HTML landing page when he pops in the disc.  Don't use non-branded scratched discs with Mickey Mouse or Naruto stickers on it though.

5. Secure your files - This suggestion is a no-brainer. Password protect your documents and make sure they are virus or malware free, particularly if you're using Microsoft Office formats. The interviewer doesn't need their system crashing midway through your story about how you manually removed malware from a dying Windows system.



6. Show AND tell - If you're allowed to bring your iPhone/iPad or Android device to the interview, show off your app, magazine, or web design using the device. Show first and only tell if the interviewer asks questions or you really want to highlight a specific feature (like how your design scales to different types of screens). Don't go overboard by bringing 4 types of smartphones, an ultraportable, and netbook to prove a point. Get ready to ask questions on how and why you designed your project in a certain way. Don't geek out or gush about Linux, Apple, Google, Microsoft, Raspberry Pi or a rival's product. Though CSS3 may not seem as complex as Java or Javascript, there is a certain style or approach to pulling it off too. Of course, if the interviewer isn't a tech guy, then it's somewhat pointless explaining to him why you chose Ruby over other languages.



Good luck to all those jobhunting this year! And if you ever become the next Mark Zuckerberg or Steve Jobs, shoot me an e-mail.

Quick Review: Microsoft Wireless Mobile Mouse 3500

Posted on 05:47 by Unknown
Category: Techtoday

So I know what you're thinking. You're doing a review on a wireless mouse? A MICROSOFT Wireless mouse? What can I say? I've written about my love for wireless mice before, but with the popularity and ubiquity of touchscreens these days, I'm now more than ever appreciating the brilliance of a mouse. That said, I do have touchscreen devices and a Wacom tablet. However, 90% of my work on my Linux, MacOSX, and Windows boxes is done with a mouse.

I actually didn't need to buy a mouse until I ended up working with three workstations overseas. The last mouse I bought, a Microsoft Wireless Notebook Optical Mouse 3000 I picked up in Best Buy Buffalo four years ago, is still working fine and is still one of my favorite accessories. For all the negative publicity Microsoft gets, they make very good input accessories. From 1998-2004, I tried A4Tech, Logitech, and Genius USB and optical mice and they died after a year. The most resilient mouse I purchased prior to the Microsoft 3000 was an A4Tech 3-wheel USB mouse (now discontinued). The expensive wireless mouse from Logitech, considered the leading manufacturer of mice, died after 11 months.

Things to like about the Microsoft Wireless Mobile Mouse 3500:

1. Off button - The underside of the mouse has a manual power off button to conserve battery. This is an improvement over the 3000, which only powered down if you removed the batteries or reattached the wireless receiver. Steve Jobs may not like power off buttons, but I like powering down my electronic devices (side note: your iPad and iPod actually perform much better after you power it down once in awhile).



2. Smaller wireless receiver - The design of most wireless devices/chips today, from Bluetooth dongles to wireless chips, is to shrink it or make it almost invisible to the user. I have mixed feelings about this if they are separate components, mostly because I'm careless and absent-minded. However, the 3500's wireless receiver docks into a spring-loaded receptacle underneath the mouse. I found out this design has been around for awhile now (remember, I've stuck to my aged 3000 mouse for years). There's a button that releases the receiver when you're ready to connect it to your desktop or laptop. Frankly, it's these simple innovations that impresses users like me. Now if only I can remember to unplug the receiver from my company laptop every time I use it . . .



3. Microsoft Mouse and Keyboard Center - Windows gets plenty of flack for their Windows Update but I've had no issues with it myself aside from the occasional Intel HD drivers that confuse my Nvidia Optimus chip. One advantage of running it is getting sweet utilities like the Microsoft Mouse and Keyboard Center. It's available on Windows 7 and the theme is version agnostic though it looks better on a Windows 8 system. The Microsoft Hardware team made a very visual approach to the configuration screen for their mice and they deserve credit for it. The Mouse and Keyboard Center's simple and streamlined design is also functional with easy to understand options for configuring macros for the mouse button. It's clearly made for the young and modern user with links to Facebook and Twitter and several click buttons on the bottom for accessing articles on ergonomic use of input devices. Take a bow hardware team!






4. Works great in Linux - Anyone who visits Unsolicited But Offered regularly knows I won't let an article pass without mentioning Linux. Forget about the politics, the 3500 (like the 3000) works well on openSUSE, Lubuntu, and FreeBSD.  It may not be a big deal but Linux support is important to users who want a resilient and functional accessory. And yes, the Xorg settings and KDE mouse configuration settings work fine with the mouse. 



In the old days, I was very wary about wireless input devices. Back then, they were buggy and performance was inconsistent and I clung to wired mice religiously. These days, however, the $5 or $10 difference between a wired model and a wireless one is not a deal breaker. The convenience of having a wireless mouse, if you've never used one, can't be overlooked especially if your worktable is already littered with a tablet, Wacom, ereader, and digital camera accessories. I dread the day they discontinue production for wireless mice but hopefully, my Microsoft Wireless Mobile Mouse 3500 and my 3000 are alive until then.

Bringing Your Digital Portfolio to an Interview Part 1

Posted on 05:19 by Unknown
Category: Techwriter


Unemployment is pretty high globally but if you even spend 15 minutes in the technical forums, you would realize that everyone is better than ever when it comes to coding, programming, designing, and creating web sites. Competition is incredibly tight. Software piracy has made sure that professional software is available to students, who admirably and arduously practice at an early age. Everything from professional Adobe products to expensive CAD software and server operating systems is available for the hard-working undergraduate willing to learn. Even would-be developers with no training are honing their skills designing apps for iOS, Android, and yes, even Windows.  Ebooks about programming, security, publishing, and web development are available everywhere and everyone is getting into the game. And don't get me started about Linux (Unsolicited deals mostly with Linux after all). Don't listen to the sour-graping IT professionals who say you have to learn x or y first and "techies" you're going about it the wrong way. Choose an area you're interested and get started there. Most of the best IT professionals I met never took those expensive certifications - they took the even longer route of teaching themselves on areas they wanted to learn.

Sure, career web sites all advise that you should be in the thick of things in the cloud with an immaculate Google+, LinkedIn, Twitter, and Facebook account. Maybe you have your own domain or web site showing off your work courtesy of GoDaddy or A Small Orange. Perhaps you're a regular contributor to Github, Source Forge, or Google Code, or even a respectable tech wiki like Fedora or Ubuntu. You've also chalked up some freelance work at Odesk, collect hundreds of thousands of hits a month, and maybe get fan mail every other day too. You also probably have the most egotistical landing page on the Internet complete with your customized Flash and Java effects and studio quality photo of your mug. Plus, your online footprint is only as large as the Hulk's shoe size and free from drunken photos and sexcapades. All that is well and good but when you're jobhunting, however, it will all still come down to that one-on-one interview either at some chilly room at a company or through Skype.

When you get to that interview, you have to not only tell but show how good you are. You're going to have to prove that you actually made that web site you boasted about or wrote that Linux article that you reprinted on your blog. That Adobe Illustrator or Corel Painter masterpiece you showed off in Behance or Deviant Art? You better have the raw sketches you started off with. As for code or that app you designed, you'd better be darn sure you can prove you wrote it or at least understood it through and through (especially if the base code was open source).

I was regularly present in several hiring sessions with HR professionals a few years back (I was the guy mopping the floor just behind the interviewer and occasionally asking questions). Not all HR interviewers pop in with an odd question such as "What is the hex code for Indigo Blue?" (which actually happened to me) or "Compute how many Duracell batteries were disposed of in 1999 in North Carolina?" Unless you're being interviewed by a smug headhunter with a superiority complex or you're applying for a job you're not suited for, you're more than likely be given a realistic and fair shake. Ideally, the grizzled veteran has as much chance of being shown the door as the fresh graduate who spent most of his college years playing Diablo and World of Warcraft. The bottomline is your body of work, whether it's pro bono or during your horrible years running the rat race. You'd be surprised just how many people are hired based on a few projects they tinkered around with while hunting for work.

Mock up of a fictional ebook by the author.

You don't have to be a Mensa candidate to get started in the IT industry. You just have to pay your dues and get some concrete projects you can call your own. The emphasis here is it's your own - whether it's a simple ebook magazine layout or a .deb application for Debian-based Linux distributions. Here are a few tips and Unsolicited But Offered suggestions for those who do get to that all-important interview:

1. Your portfolio online - The most ideal situation is that you e-mail or provide the hyperlinks to your interviewer before the interview itself. It will give you a chance to talk about specific projects or designs. If you sent the company a digital portfolio in the form of a PDF, follow standardized security and formatting methods (for example, availability of fonts in OSX and Windows). If your job involves web design and technology, consider Internet Explorer despite your utter hatred for it (Personally, I think IE9 isn't so bad in Windows 7). In most cases, if you're invited for an interview the company has already decided to hire you and the interview is more of a formality to check if you really did all those incredible apps or web sites. If the HR guy has all your online portfolio before the interview, it gives him the chance to prepare questions and gauge your ability. A good recruiter will adjust his/her questions to your skill set and level based on the projects you sent (for example, a complex Excel table or Pivot Table). Like a resume, LinkedIn profile, or Facebook account, however, don't provide everything you have - you need to have something new to say if the interview falls apart and goes in the direction of "Is that all?"


Take note of all the projects, wiki articles, and code you've distributed in the cloud or posted on your web site or blog. Have your hyperlinks ready and ask a friend overseas to test if all of them are accessible, whether it's an article in the openSUSE wiki or a project uploaded to Source Forge.  Refer to your projects during the interview and provide the HR guy easy to remember sites where it can be accessed. Any apps in Google Play or the Apple iStore are always impressive. If you're allowed to bring a laptop or the interviewer asks you to show your work then make sure you know where you're going. Don't Google or Bing your own work unless you know it's going to come up in the results (or your job objective is related to search engine optimization). Always have alternate sources online in case the company blocks web sites like Blogger or Wordpress.  Although storing your projects in Sky Drive, Dropbox, or Ubuntu One may seem like a good idea, downloading them one by one is extremely inconvenient for the impatient interviewer.



2. Your portfolio OFFLINE - You won't always be allowed to bring your laptop or tablet to an interview but if you do, make sure that your device is ready to display your work. Moreover, make sure your device wallpapers are safe for viewing and don't have Maria Ozawa or Alexis Texas on display. I don't recommend handing your laptop to the interviewer unless requested. Request for a projector or handle the navigation yourself. If you have illegal or pirated software installed, don't show off the software. Personally, I'd recommend booting into a Linux distribution - you'll prove to your interviewer that your project looks good in another platform and you'll avoid any unnecessary performance issues or errors that may occur in Windows (such as Acrobat Reader crashing on you) while you're running your demonstration. For aspiring digital artists, it actually makes sense to have high-resolution print outs of your vector or bitmap designs. Although your Canon or Epson inkjet printout on high-resolution glossy paper can never match the experience of looking at a PDF magazine, complex vector or CAD art on a big LCD screen or even a Retina display, it's something substantial the HR staff can refer to without having to open a browser or access your online files. For those who are planning to show off their digital animation or movies (or just want to demo their work visually and with sound), get one of those Pico projectors by Acer, Samsung, or ASUS.



These projectors may not have the highest resolution or the colors of a Sony Bravia, but it will make you look professional and ready at the drop of a hat. Finally, it also goes without saying that handing an iPad loaded with your work to the recruiter can be pretty impressive. I'm not an Apple cult member but an iPad displaying animated CAD designs and interactive digital magazines can wake you up during an interview. Don't discount a 7" budget Android tablet though especially if your code, web design, or art is for distribution - showing off your work on an Android device shows accessibility.

10 Reasons to Love Lubuntu 12.10 Part 2

Posted on 05:54 by Unknown
Category: Linux

Continued from 10 Reasons to Love Lubuntu 12.10 Part 1


6. Lightweight - Like most Linux distributions, your installed applications and how you maintain your system affect your performance more than your hardware. My poor man's older Core i3 and 6GB of RAM Lenovo Ideapad Z360 isn't a powerhouse system but with Lubuntu, the system boots up at a respectable speed and can convert audio (using Sound Converter), rip video (AcidRip DVD Ripper) and convert ebooks (using Calibre) like a champ. Unless I have to create illustrations using CorelDraw or Adobe Creative Suite (or run iTunes), I prefer staying on my Linux install rather than booting in to my admittedly long in the tooth Windows 7 (which hasn't seen a fresh reinstall in over a year). Although LXDE is advertised as a lightweight desktop environment, good maintenance and acceptable hardware can make Gnome 3, KDE4, and even Unity fly on your system - though I do prefer no-nonsense and no-frills LXDE over other environments.

"Did anyone say lightweight?" 
Spidey shows just how strong he is (and embarrasses the current inept Spider-Man writers) in Amazing Spider-Man #320 (1989). 

7. Works perfectly on the Lenovo Ideapad Z360 - Despite the infamous 1GB Nvidia Optimus graphics-switching chipset the Ideapad Z360 comes with, Lubuntu doesn't have to butt heads with any Nvidia issues. Whereas I lose some of the desktop experience when running Unity or Gnome 3 on the Ideapad, Lubuntu just loads a productive desktop where I can get work done on LXDE. You would still have to adjust brightness settings in Windows 7 prior to booting into Lubuntu (or switch off the Nvidia chip via the BIOS), but otherwise I'm free from the 3D errors I get in Unity or warning messages from Gnome 3. Ubuntu's exceptional hardware pedigree also makes sure that Bluetooth and wireless on the Ideapad works. For those who use Skype on Linux, the notorious audio issues (which occurred in my openSUSE installation) aren't present with Lubuntu on the Ideapad. Even my webcam and Wacom, two accessories I don't use very often, work well on this system.

8. Great for first-time Ubuntu users - In the old days when you wanted to convert a Windows or Mac OSX user to the penguin flock, you would show them Ubuntu's mainstream release, which ran Gnome 2. Nowadays, Ubuntu's mainstream desktop Unity is so divisive that when introducing Linux, it's not exactly the best showcase any more (Unity Lens anyone?). With Lubuntu's sleeker theme and frugal application set, it's easy to show off basic Linux features such as paging through virtual desktops (which Windows doesn't have), great boot up speed, performance, and a huge application library via Lubuntu Software Center or Synaptic Package Manager.

Lubuntu Software Center's non-flashy interface belies a stable experience.

9. Classic desktop experience - Ok, ok, I do appreciate the innovations of Enlightenment 17 and the improvements around Unity. However, at the end of day, I just want a distraction free desktop without too many settings, an accessible menu, and a malleable user experience. On occasion, I do open up Lubuntu's LXPanel, which is a simple reminder of my available applications and utilities. In the same way that openSUSE and KDE make an excellent pair, Ubuntu and LXDE also makes sense for the serious and productive user.

10. Teaching Linux - When teaching Linux, there's a reason to either go for Xfce or LXDE. KDE is great (I use openSUSE 12.2 KDE on two of my production machines) but teaching a student to navigate the occasionally overwhelming KDE configuration settings can be too much. Although Ubuntu is widely considered to be one of the more well-represented distribution releases globally, Unity isn't. Getting a new user to adopt it as Linux's "de facto" desktop environment isn't always a good idea. Lubuntu has the benefits of Ubuntu while making sure a student is flexible enough to understand the difference between Linux itself and the desktop environment. You can show them how to set up a powerful file, SQL, Nginx, or web server without having to worry about the graphical user interface and at the same time not scare them away by working solely on the LXTerminal (but you could do that too). You can even have a fast workstation for programming and practicing markup language. Demonstrating how the Internet works or how packets are exchanged on a network is easy on a Linux box. Installing educational programs is also problem-free with Lubuntu since it isn't heavily dependent on KDE or Gnome packages. With LXDE's low resource consumption, you can load Blender, Scribus, Inkscape or gaming engines like Steam or Humble Bundle without worrying about hardware resources or frame rates. Finally, if you just want to play a documentary or a foreign language video tutorial or access Google Maps for geography lessons, Lubuntu's got you covered with Java, Chromium, and Flash. As for multimedia players, the Ubuntu repos are all yours for exploring.  

6% CPU usage even with several productivity applications running.

Linux on Film: Antitrust (2001)

Posted on 05:38 by Unknown
*All screencaps from Antitrust (2001)

Long-time Linux users are familiar with Antitrust (2001), which was strongly advertised as a movie that would inform the masses about open source and Linux. I'll leave that discussion to archived forums and avoid the open source and Linux politics that came with this movie. Suffice to say, I enjoyed this movie when I watched it in the cinema way back in 2001 and I highly recommend open-minded cinephiles to give it a shot - Linux background optional but recommended. Wikipedia and IMDB both provide excellent summaries of this flick along with a brilliant list of Linux-related trivia so I won't retread that path (click on the links if you want some juicy details about ex-Gnome developer Miguel de Icaza's cameo).

The film, which was actually made in 2000 and released in 2001, features two very attractive young actresses, both of whom have gained a career resurgence of late. A young Claire Forlani before she was defiled by Death in the form of Brad Pitt (Meet Joe Black - 1998) and a shriveled Gary Sinise (C.S.I. New York) is the geek hero's girlfriend at the onset of the movie (if you could believe that!). Cutie Rachel Leigh Cook, whose hypnotizing doe-eyed stares can melt any icy-cold binary programmer's heart in a second, appears here as the geek hero's attractive co-worker. Claire Forlani (who appeared in 2011's TV series Camelot) and Rachel Leigh Cook (who is currently co-starring in TV's Perception) both seem oddly appropriately cast in the movie since they seemed spaced out half the time while all the "techie" stuff happens. This is perfectly fine since baby-faced Ryan Phillippe (the main protagonist) and low-key Tim Robbins (the main antagonist) both downplay their performance. After all, it's hard to get excited about code, right? Still, the movie does get pretty exciting towards the end even if you had no idea what Java instructions Phillippe is compiling during the climax. Antitrust even gets pretty hot if you watch the version with the deleted scenes (the lucky dog Phillippe gets to have romantic sex with innocent Cook and rough sex with scheming girlfriend Forlani).


Gasp! Someone's using a landline phone! (Hey, you're looking in the wrong area. This is not that kind of blog.)


Sigh. If only my computer lab partner looked like her . . .

Admittedly, Antitrust hasn't aged well from a plot standpoint. In fact, the idea of killing people for their code seems somewhat silly since you can do all of that a thousand miles away from your victim without leaving your seat at Starbucks and while listening to Sting and downloading a torrent of Downton Abbey. Moreover, villifying Bill Gates and Steve Jobs, which the movie does in the form of Tim Robbins, seems out of fashion considering that Bill Gates no longer heads Microsoft and is a respected philanthropist while Steve Jobs is venerated by millions of people around the world. In fact, some people will punch you in the face if you even say Jobs had a bad haircut (that's the Apple cult for you). The conspiracy of paying off people to stalk and influence genius programmers (which the lovely Claire Forlani does in good measure) seems a bit over the top. Antitrust did win some awards despite head-scratching fake scares like the homeless man that pops into Philippe's car. Another head-scratcher is the 3-minute screen time of Richard Roundtree - the actor who played the classic detective Shaft in the movies (Linux should have a Shaft theme song). Worst still, the filmmakers reserve the most frightening music when they zoom in to a plastic computer mouse outside a building (which the movie hinted 15 minutes in as the source of the company NURV's malevolent monitoring). The music gets even more creepy when Phillippe sneaks into the daycare center and accesses the cleverly hidden back up servers. I hate to admit it but the sight of programmers being monitored through a daycare center seems more insulting than horrifying.


Being watched by staff and the kids at the daycare is absolutely terrifying.


Beware of the mouse outside the daycare . . . it could be disguised as a broadcast dish.

Although Microsoft and Apple get indirect and direct references in the movie (a Mac is shown prominently in the end), the company which hires Phillippe's character, NURV, is actually more representative of Google, which in 2000 wasn't the juggernaut it is now. In fact, when Rachel Leigh Cook and Ryan Phillippe's character searches for media companies to help them, they actually use a Yahoo search engine (Oh, the horror!). Back to Google. Anyway, the very modern and comfortable NURV headquarters reserved for tech geniuses in the movie is remarkably prescient of Google's own headquarters. Keep this in mind if you end up in the theater watching this year's The Internship with Vince Vaughn and Owen Wilson.


Gasp! Someone's using Yahoo! Search.


Gasp! A PDA! And it's not colored!

Watching the movie again after more than a decade was extremely fun even though I knew the plot already. Part of the entertainment was hindsight, seeing black and white 8-bit cellphone and display screens, Yahoo! during its heyday, the utter amazement of Philippe's character when he found a suspicious piece of fiber optic cable in an apartment, the use of a Java compiler on celluloid, and the words "open source" being used in a movie. Although both IMDB and Wikipedia mention that an old version of Gnome is prominently featured in the movie, it actually gets less than a minute's screen time (I had a hell of a time getting a screen capture). In fact, NURV's vanilla-flavored security system and a brief segment running Unix commands on a terminal gets more exposure.


Synapse Java


Isn't that a bit melodramatic? These days we just go to Github.

Well-known open source and Linux luminaries do get a nod in the film's credits, but don't expect a full-blown conversion to Linux once the film ends. In fact, the only images you'll actually remember are of Rachel Leigh Cook and Claire Forlani's. Unfortunately, you'll also realize that girls like them don't always pay much attention to guys who spend too much time in front a monitor/keyboard and know several thousand Unix commands. Ryan Phillippe's character was irresistible because he was attractive, a genius, and lucky enough to have two lovely ladies conspiring against him. Only in the movies.


Look familiar Linux fans?
