Ol’ Reliables

November 16th, 2009

I couldn’t tell you when I actually got my first computer. I can tell you that I first got an old used Tandy TRS-80 color computer from someone with loads of games and software. It came with a 5 1/4-inch floppy and an actual color ink-jet printer! I had the computer for a little while before it started to become difficult to load programs and then the thing just stopped working. I don’t know how old it was when I got it, but it was old.

My next computer was a used Apple Performa 400. My first computer that was really usable. It ran some version of System 7, had a geoport 56k modem, and a 15-inch monitor. The computer came with some productivity software (Claris Works, Pagemaker) and some games (Sim City, Myst, Doom II). The hard drive was 750MB. Although the thing never died (computer or hard drive) the system would just stop working from various System 7 related crap. I lost it 2 times in the year or so I owned it, and finally I let it go.

Macintosh Performa 400

As you can tell from the title, this post is obviously not about those machines. No, this post is just about systems I have had that never wanted to go. They never died, I never had major hardware issues, just the occasional software hiccup. I’m going to start with my first REAL machine. It was a no name brand custom PC purchased sometime in 1998.

My parents finally decided it was time for me to get a real system. After years of begging for a real computer our friend Rocco decided to put it on his credit card for my parents and actually get me a full, new, computer system. We drove to this computer store way out in the middle of no where and look around a bit. My dad and Rocco had no idea what to look for, but I did. I found one machine that stood out from the others; 300mhz AMD K6-2 processor, 32MB SDRAM, 56K modem, 8MB onboard VRAM, 52x CD drive, 4GB hard drive with windows 95, a beautiful 17-inch monitor, and even 2 USB ports! This was it. I wanted it, and I got it for $975 with a year warranty.

I was one of the only people on my block to have a 56k modem, and a computer that could play games and movies and music. I was one of the first people out of all of my friends with a new computer all to himself. I started eBay-ing at around 15 or 16, when I got my first job. With that money I started to upgrade my system. I upgraded the video to a Savage 4 PCI card, a Diamond audio sound card, I got up to 96MB ram, a CD-R (which was $300 when I first bought it), I added a 10GB and a 12GB hard drive for music and programs, and used the original 4GB Seagate drive as the system drive. I installed so many versions of Linux and windows it could make your head spin. I formatted it so many times I lost count. It was on almost all the time, hours and hours of intense (at the time) gaming, loud music, viruses, everything. I just worked that machine for everything it was worth and nothing inside it ever failed. Then I finally “upgraded” to a 450Mhz P3 Dell Gigaplex which was given to me from my old school library. I re-purposed the old machine as my own personal webserver (I had Cable internet in my house which another thing I really adopted first: getting the best internet in the neighborhood…before cable was DSL).

The old webserver lasted through most of my undergraduate career sitting in my bedroom at home (and then our house in South Philly) idling on my cable connection 24/7 for maybe 3 years. I used it to host various things (pictures, my former website, friends’ pics, class projects, etc). In 2007 or so I finally decided to take the server offline, and drop the cable internet. I was never home anymore, and my parents didn’t go online at all, it was just an extra $45/mo that wasn’t going anywhere. The system was still using the original 4GB Seagate drive, original USB controller, original RAM, and the original video card (not the Savage 4) and even the original power supply. All working when I took it offline. It was slow, the CMOS battery kept dying (which I replaced 2 times in its lifetime), and it was loud from the old drives and old dusty fans, but it still worked perfectly.

The replacement Dell I had was tossed for an upgrade I got in college, another old Dell Dimension XPS with 700mhz P3 (The old Dell wasn’t dead, I just traded it for the other Dell). It was an old webserver years before, and I used it as my computer in my dorm for a few semesters. Many papers and hours of movies and gaming occurred on this machine’s life in my dorm also. It’s now used as my parents only computer at home. It’s running XP, has wireless, 512MB RAM, 2 hard drives, and still works fine.

My replacement for that, a PowerMac Blue and White G3 is sitting in my basement in Philly. It has a G4 upgrade in it, a 20GB and a 40GB hard drive, a DVD-R/RW, 512+MB RAM. That computer is from 1999, and it still works. I got the Mac from my current employer who was throwing it out. The original 60GB drive died on it (which is only my second drive failure in my life, my other was my old Toshiba laptop 5+ years into its life) and the system needs to be reinstalled…but it still WORKS.

Blue and White G3

I have a lot of hardware like the the Dell and the Mac; my old third-gen iPod (still used for storage!), my old Toshiba laptop (needs new hard drive, screen hinges are breaking), and other various systems I have built over my life. These all still work fine. Is it something I do to my systems that make them last longer? I like to think so. I like to think that I do take good care of my systems and try to get the most life out of them. Maybe it’s also that I just don’t thrown systems out at all until they are completely useless to me. Whatever it is, I have surprisingly good luck with hardware. I’m going to be replacing the Dell at home with an actual new computer sometime in the near future, but that dell will be reused as a server somewhere I can assume.

I’m not saying I have the best luck with machines, older entries clearly state that that I don’t, but I do have surprisingly good luck.

So I wonder, why do people have so many issues with their new machines which they spent thousands on and I have almost no issues at all on older systems? Do they not make computers like they used to? Is hardware getting crappier? Or is it that performance comes with the high price of high failure rates? I can safely assume that a 10,000RPM 700GB drive will get much more wear and tear on it than a 300GB 7200RPM drive, but shouldn’t the failure rate be lowered as time goes on with technology? We have better materials, and better methods of testing hardware now. Should we just stick to old hardware because it’s “safer?” Or should we just accept the high failure rate because performance is worth much more? I wonder.

Issues with WiFi and Vista

September 18th, 2009

In my lab I keep a wireless access point active; mainly for students and profs using it to connect computer together for whatever. I used to use a WPA password for the system. WPA worked fine except that many people who were not supposed to be on the network were on there. Students would give the password out, and this annoyed me. That network is supposed to be for DM staff and students only, that’s why I have it separate from the schools wireless.

Over the summer I made a lot of changes to the network, mainly I changed it over to use WPA2 Enterprise with our RADIUS server. The logins are taken from our Open Directory LDAP (the ones people use to log into our machines, website, wiki, etc.) and thats how people connect. Works great in MacOS, I select the network, put my user and pass in and voila! Windows was another story.

My MBP has Windows 7 Ultimate; I was able to connect to the network after changing some WIndows defaults. It does ask for a login, which is better than what XP did, but it still had some issues. I had to disable the “Check server certificate against blah blah”, because it’s a self-signed cert it wouldn’t work. I also need to disable “Use windows login password to login to this network.” I understand most people using “enterprise” networks all use AD or whatever to login to their computer, but why make that default? Not to mention, to change both of these options it’s 5 levels down or so buried deep in the wireless preferences. It’s impossible to change if you don’t know what you’re doing.

Windows 7 connects fine now. No issues, it’s actually very stable. Issues arise when Vista users connect. Now, when I add the network for a Vista user it comes up as WPA2 Enterprise (good), AES (great), it even prompts for a user and password (excellent). No connection. I change those settings above again, because it’s by default, still nothing. I go into even more advances prefs by changing the authentication method to MSCHAPv2 or TTLS, PEAP, whatever works. Nothing works. I check all of the Vista prefs with my working Windows 7 prefs, they are identical. What is the issue then?

After a good Google search, and more and more searches, and stops to Apple discussions, and everything else I can think if, I see similar results. Apparently Windows Vista HOME does not work with WPA2 Enterprise. It just doesn’t work. It’s “broken” as some would put it, or “disabled.” Whatever the reason, my question is “Why??” Why do you put WPA2 Enterprise network prefs and even allow me to add said network to my computer when I can’t fucking connect to it? Explain that one, please! If you don’t want Home users to connect to enterprise networks, take the fucking thing out, don’t just make it act like it works and then not let it. How do I know it’s a client issue and not a server issue? Logs.

My server logs all RADIUS connections and attempts to authenticate. My server issues the challenge to the machine, but the machine apparently ignores it, or throws it away, or wipes its ass with it. It does NOTHING.

Now, I was having this issue with some other computers as well, Windows XP users. Their main issue was that they didn’t have updated drivers or settings were screwed up, but they eventually worked most of the time. I’ve also tried with some Vista Pro computers, and yes it works most of the time. The times it doesn’t usually work, I tell the people to get the software from their card manufacturer and use it, and then it seems to magically work.

What is wrong with WIndows wireless? You got me, but I finally told those people who couldn’t connect to either upgrade or deal with it and connect to a poly network. Hell, Poly’s putting N-Wireless in, I might just use it from now on also!

Battle of the Bulge: A Battery Story

September 1st, 2009

If you own a Mac laptop you know that the adapter has a little light on it; green for charged, amber for charging or bad. The light on my adapter (which is not the original adapter, but a replacement from Apple themselves) stopped working properly a long time ago: the light would not come on in most cases unless I jiggled the cable for a bit and then never touched or moved it again. If I moved, it went out. I thought this was a contact issue on the plug itself, I’ve seen many people have the same issue before. So I thought nothing of it. Not to mention, my battery was fine, 255 cycles after 2 years and I still got 2+ hours on a good day.

Last week this changed when I noticed my laptop spontaneously turning off at random points during use. Even when fully charged it would cut off, and not allow me to start unless I plugged it in, even though there was a 70% charge on the battery. Fed up I decided t was time to bring it in for service, again. The night before I was going to bring it in brought on a whole new issue. After placing my laptop on the table I noticed it was not sitting evenly. I look underneath and notice the battery is sticking out…maybe it’s not plugged in all the way? I pop the battery off and find it to be bulging outward!

MacBook Pro battery with a bulge...

This is a very dangerous thing to happen to a battery. So now I know there is an issue and my battery is not “just old.” I brought it to Tekserve the very next morning and after 2 hours of waiting and checking they determine that not only is the battery bad, the adapter is as well.

Why am I writing about my battery? I’m mainly writing to talk about how Tekserve tested and made sure there really was an issue. The woman who helped me took my laptop to the table behind her and popped in a USB stick with some sort of battery/adapter testing program from Apple. The test came up as both “Good” at first. She retested, both came as “bad”. She retested, one came ad good, one as bad, etc. She did this at least 4 times, and then tested with a known good battery and adapter, and came to the conclusion that “AFTER NUMEROUS TESTS I have deemed that both are broken and need to be replaced.” She found this out after TESTING what I told her to test.

So a few things to keep in mind here:
1. If your battery starts to bulge, please get it replaced and stop using it ASAP. It’s dangerous.
2. It might not be just the battery, get the adapter checked.
3. Tekserve tests their shit…as everyone should.
4. A new battery and adapter make me happy.

Now I have a 1 cycle battery for free:-)

Computer Repair is ever complete without…

August 6th, 2009

TESTING!

When I am given a computer to repair by a customer (or anyone to be exact!) I do my best to be quick with the job as well as do it RIGHT. I test everything about the computer that I changed/fixed/replaced. I do not want people bringing their computers back to me for the same issue, it doesn’t make sense for someone to have to bring their machine back after I just fixed it. Unless it’s something totally different.

Why am I writing about this now?

My MacBook Pro iSight seemed to stop working randomly one day. I tried to use it and it didn’t work. System profiler didn’t show it, something was wrong. I brought it to Tekserve first. They claimed that it was hardware but since I had a small dent on my computer (no joke) they wouldn’t cover the warranty because Apple would deny it. I found another place in the city which I was told would take laptops in almost any condition as long as the condition wasn’t the cause of the issue and repair it under Applecare. Sure enough they replaced my logic board and my iSight worked again. I got my computer back in 2 days time.

I get home I try to use my DVD drive and find it doesn’t work. System profiler acts weird saying it works sometimes….then it doesn’t….whatever. I open the laptop and re-seat the cable. It loads a DVD but when I start doing reading from the drive it loses it. Something is obviously broken. I take it back and explain to them the issue. They take it and call me 2 days later saying they cannot reproduce the issue and it seems to work fine. I say, well, if you say it’s working fine, I’ll come by to get it. I get my laptop home and sure enough, same issue. I bring it back the next day. They claim they put a DVD in it and it read it so they deemed it as fine. Really? You did exactly what I told you I did and didn’t think to read from the drive?

After a conversation I tell them to replace the drive ASAP; meaning get the part and call me when it comes in so you can install it right then and there because I’m tired of not having my laptop. They install it and tell me to come back because it’s fixed! GREAT! I go and ask “Do you have a disc I can boot from?” He hands me a Leopard install disc and sure enough the disc does not load at all. Mr. Tech then tells me “Oh you have a third-party boot software (rEFIt), it’s probably the issue. It wasn’t hardware, it was YOUR software.” I then need to explain to him that it was fine until they replaced my logic board. I also ask “did you replace the ribbon cable also?” to which I never get a straight answer for (No). The tech doesn’t believe me, so I uninstall rEFIt on the spot and boot. The disc gets loaded, oh my god! He then gets a smug look on his face and says “It was obviously the software, see it’s loading.” After waiting 15 minutes, it doesn’t load. This was about the time where I wanted to shove the guy’s face into a wall; he finally takes my advice and boots from an external drive, HIS DRIVE, and goes into system profiler. The drive is no where to be found. Thank you. Hardware failure.

Now, I am told that they need to send it to Apple for repair. Why? All you need to do is replace the god damn ribbon cable, and if that doesn’t work, the logic board is bad. It’s not difficult to diagnose!

So, after 4 trips to this place I lost my laptop for at least a week now all because the tech’s didn’t test the repair properly. If you install a new optical drive, or if a user says “something is wrong with my optical drive,” what should you do? Should you pop a disc in and say “Oh it showed up, it’s obviously not broken at all?”

NO!

You put in a disc, read from it, install something, burn a disc, ANYTHING THAT TESTS THE DRIVES OVERALL PERFORMANCE! NOT THE EJECT MECHANISM! NOT THE [does the disc load, software?] MECHANISM!

What have we all learned (except Digital Society apparently)? Test your repairs!

Choosing the Right Programs for a Lab

August 3rd, 2009

Sometimes it’s tough to stock a lab full of computers with software. You want to get the best software of course but that usually means the most expensive. Sometimes the expensive programs aren’t even the best either.

The lab is primarily used for video editing and 2D/3D graphic design. These are three very expensive fields when it comes to software. For video editing we use Final Cut Studio 2. We have a lab license which allows us to run 5 copies at any single time; this license costs us a one-time upgrade fee of around $2000. Of course we had to have Final Cut Studio before that so you need to factor that cost into it also. I’m not sure how much it was originally, but I’m guessing between 2 and 5k. Now, we don’t pay a yearly fee or anything, it’s installed, and it works. No fuss. Is there anything else out there we could use, something free? Maybe cheaper?

In short, no.

There really is nothing like Final Cut Pro out on the market. (And don’t tell me Adobe Premiere Pro because I’ll just have to punch you in the face) Avid is around, it’s been around, it will probably always be around; but it’s not FCP. Avid is a whiny little pain in the ass that doesn’t work if it doesn’t get it’s way, not to mention it’s about $2000/license. No thanks. So FCP is something we’re stuck with it looks like, no big loss. (I know there are open source editors out there, but they’re just not as good and intuitive as FCP is at all, so don’t bring that up.) With respect to Adobe, we do have 1 license of After Effects. It hardly gets used, but it’s really a good program from what I’m told.

Next is 2D graphic design. This one is a bit simpler. We use Adobe Creative Suite 3 (no, we didn’t upgrade to CS4) which comes with Photoshop, InDesign, Illustrator, Dreamweaver, Flash, and Acrobat Pro. We’ll ignore Flash for now because we really can’t use anything else that I know of. Photoshop is the standard graphics/photo editing software, the weapon of choice for graphic designers if you will. Without this piece of software your digital media lab (or in this case, my lab) is a laughing stock of the DM world. However, there are freebies out there, although they might not be as good they sure as hell will do the job well. GiMP and GiMPShop are around and have been for a long time. This Linux counterpart to Photoshop gives users who cannot afford the price tag from Adobe the ability to make beautiful graphics like the pros. It’s tools are almost 100% similar, and it’s interface can also be with the help of GiMPShop. I would show screen shots comparing the two, but I can’t seem to get GiMPShop to run on my laptop. (BTW, the two run with X11, not natively.)

InDesign and Illustrator are programs I am not so sure about replacing, I’ve never tried alternatives to them. I know there are a few out there though. Inkscape is one that looks like a promising Illustrator replacement, it’s free too! For InDesign we have Quark of course; although Quark is rapidly getting replaced my InDesign, and one called Scribus, another open source replacement. I’ve never used any of these so I cannot speak for them, but if you’re looking, try them out!

Dreamweaver is for web-development. It’s more of a helper for most new developers. It’s gotten a lot better over the years, but it’s still nothing that cannot be replaced by good ol’ hand coding with TextMate or whatever editor you prefer. These are all wonderful, some are free, some are not. However, for true web editing I have to give props to Coda by Panic. I’ve mentioned before that I love this program. I do. I really think this is probably one of the best code/web/css editing programs on the market, ever. It’s beautiful, and it’s functional. It’s also $99. Does this bother me? No. Each penny of that $99 is worth it. If you’re just doing web stuff, don’t go near Dreamweaver, get Coda, as a matter of fact, get multiple copies of Coda to give to friends. That’s how much I love it.

Look at this beautiful CSS editor! I can also edit the code of the CSS and ANY OTHER CODE WITH CODE HINTING!

Now we come to 3D graphics. Our choice program in the lab is Autodesk Maya 2008 Unlimited. Maya is the “industry standard” for 3D graphics, right with 3D Studio Max; both of which are now owned by Autodesk…weird huh? Maya comes with so much stuff that it’s very hard to find a comparable program. Some difficulties come up with licensing (you need to be running a license server if you have a set number of licenses, and you need to make sre you get Unlimited or Complete. The difference is just what kind of fluids or fur you get, whatever. I like Maya to a certain extent. it’s powerful and fairly easy, but it’s licensing is annoying, and it costs a good amount for upkeep. We need to constantly upgrade if we want the bugs to go away (because lord knows you don’t want to keep fixing your software after the first service pack which we paid a few thousand dollars for in the first place) and if we want service for the license we bought, that’s also more money.

Maya's starting interface.

To replace Maya many people opt for Blender; Maya’s open-source cousin from the Dutch. Blender is completely free, and it does a lot of the things Maya does. It really is an excellent replacement for Maya; however, it’s got a steeper learning curve than Maya. While Maya may still be considered difficult to grasp anyway, Bender is like a nightmare to some 3D artists I’ve known. So if you can learn Blender (which by the way has all documentation online free as all good programs should) you will probably be very happy with the results.

A random screenshot from Blender 2.4 from Wikipedia.

Besides these main programs I have taken liberties to find free versions of other programs for my lab machines as replacements to troublesome or other non-free programs. Adobe Acrobat 9 has a nasty issue with network users on Mac OS, it crashes…all the time. I’ve taken Acrobat off and replaced it with a PDF plugin for Safari and Firefox. If someone wants to use Acrobat Pro, which is VERY rare here, then they can ask me to install it for them, for now Preview works just as well. AppFresh is a free program that checks all of your programs for updates and allows you to install them at once. very handy for updating the lab machines. And I can’t forget my favorite free buddies Carbon Copy Cloner and DeployStudio, without these FREE tools I would have be dead trying to deploy the lab and backup systems.

So, if you’re on a tight budget and you’re looking for cheaper alternatives, try out some of these. They might end up being better for you in the long run. If you have any other programs to suggest, drop a comment, I’d love to try some new programs out. Just remember, sometimes you don’t get what you pay for.
