Write something.
Here's a tip.
Write a paper for a trade or online magazine. It doesn't have to be a doctoral thesis. Just a simple "Hello World" article will suffice. Be sure it's a topic that hasn't been beaten to death and be sure it's a topic you know cold. "How to" articles are always in demand at places like IBM's DeveloperWorks or JavaWorld.
You will be surprised how impressive even the simplest article will make your resume look. Being an author makes you an expert in the eyes of your typical HR resume reader, especially when compared to your typical "C/C++/Java/Perl/VB/PHP/......" resume.
Good luck!

General information on spintronics
For those (like myself) who have little idea about spintronics, Wikipedia has a general article that seemed to explain it to me quite well. Of course, I'm not a physicist so I have no idea whether or not it's accurate although I'm tempted to find out more from the referenced article. PhysicsWeb has more of the same. Apparently this will have far-reaching implications on RAM and cable bandwidth.

GPL incompatiblePostfix is covered by version 1.0 of the IBM Public License. The Free Software Foundation says:
IBM Public License, Version 1.0
This is a free software license but it is incompatible with the GPL. The IBM Public License is incompatible with the GPL because it has various specific requirements that are not in the GPL. For example, it requires certain patent licenses be given that the GPL does not require. (We don't think those patent license requirements are inherently a bad idea, but nonetheless they are incompatible with the GNU GPL.)By the way, that same FSF page says the same about IBM's other open source license, the Common Public License, used in Eclipse.
I hope that a future version of the GPL will allow LGPL-style linking with code covered by GPL-incompatible "free software" licenses in cases where no proprietary software is linked in or perhaps that a future version of the GPL will address software patent problems in a way that is compatible with the IBM Public License and the Apache 2 License.
In the meantime, to me, the advantages of Postfix are less than the disadvantages of the obstacles to future code recycling. If the incompatabilities could be fixed by a change to either the GPL or the IPL, and if enough of the hype about postfix proved to be real, I would probably switch to postfix.
I know I am a statistically insignificant sample, but there are others, mostly developers, who care about being able to copy code between free software projects in general and GPL compatability in particular. So, Postfix gain that much more usage and support if and when this incompatability is resolved, such as, for the short term, by adding some exceptions for the GPL, as the CUPS project did.

Re:High level of skill?Ok, I'll bite. I agree high level of skill is a relative term -- but I think he was implying that his skill level is high relative to the general populance, not the rest of the developers out there. I've found more idiots applying for programming jobs without CS degrees, than with though I agree there are idiots a plenty in both categories
Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning. -- Rich Cook.
All I really know, is that the people who show up with a degree in English, and want to code, rarely work out.
If you don't mind the advice, I think the problem may lie in how you interview. It's hard to do a good interview for a programing job, especially for those of us who still consider ourselves coders, but the preperations will pay off.
I ask the usual character questions -- do you like Star Trek? Could Superman beat up Darth Vader? Do you think it's ok to put mustard on a Roast Beef sandwich? And so on. (kidding of course).
I also do a whiteboard test of language neutral tasks. Using an OO language the interviewee and I make up on the spot (syntax only of course) we build a program that can, given a list of all the flights in the US, tell you the fastest way to get from point A to point B, at any given time. If they actualy understand the math, that's even better, but I'll settle for us making progress towards a solution, and seeing their designs. I also do a Meta-language example, where we, on the whiteboard , build a Turing machine (though I don't call it that during the interview, we just talk about rules for our machine) that will be able to recognize certain things. I also will frequently run Robocode and then looking at the API with the interviewee, ask about the robot they would make.
I agree that this sort of stuff does give the CS grad an advantage -- they've probably had discrete math, and ougta understand nodes, edges and the pumping lemma. But I think that these concepts are generic enough that a person with no "formal" training can still arrive at good answers. I also think though that this reveals the CS students who can parrot what they heard but didn't "understand." I find these sort of thngs very valuable in revealing CS majors who can talk the talk, but can't code their way out of a wet paper bag. I'm not saying I've never hired a dud, but I can say (knok on wood) so far I've avoided the "negative work" employee, who is so bad it takes another developer to fix everything this 1st guy broke. As for the entry level positions, and salary, I wrote some thoughts about essential skills. If you have the skills I describe, you should take the job, and start working -- you'll get promoted quickly. And none of that has to do with a degree -- it's attitude.
in fact, like backov, I'm wary of too much education --if you have a BS and an MS in CS I'm wary of you. I'll want to know why you didn't go work right away with a BS. If you have a BS in CS, I'm gonna want to know what programs you made for yourself, for pleasure, and not for school. You should have a simple website somewhere too. PLEASE have a web site somewhere. If you don't have your resume available from your home page, along with a few other docs, you won't do well in this field. And if you're just out of college, you should have a student web page right? Finally, you probably know if you're a star or not. If you are indeed a star, take the job if it's cool, and don't worry about the money. Learn from the greybeards around, and realize that you're gonna fly the coop soon enough anyway. Most developers get their best raises by constantly switching jobs. If you're not a star, friggin RECOGNIZE that, and embrace your roll as a "behind th

Five Computers quoteIn fact, Babbage once said there was only a market for five computers in the world.
Wikipedia says it was Thomas J. Watson who said that in 1943. This was shortly before Thomas J. Watson Jr. came home from WWII and began promoting computers heavily within IBM. Other web source seem to agree. IBM doesn't seem to endorse it in official material though there is a presentation sitting on one of their sites that mentions it.
Whether or not it's true, the lesson of the quote is that even (especially?) people on the brink of a tipping point may not recognize the huge impact of the disruptive technology they are working with. Works the other way, too. Often those promoting some cool, geeky technology assume everyone will want one, when in fact they don't; at least not yet. Look at the many early attempts at "portable" computers or the many attempts at handheld devices and runs at tablet-style PCs. Ultimately, some of those technologies caught on (and tablets still look like they might) but at a much slower rate than anticipated.

Re:She looks halfway decent at leastGNAA Press release:
GNAA claims responsibility for kidnap of Olsen Twins
By Gary Niger
Lindon, Utah - GNAA (Gay Nigger Association of America) this afternoon announced one of their loyal members was responsible for kidnapping the twins inside a popular New York Club, Vudu Lounge (Websites).
In a shocking announcement this afternoon, GNAA representative rkz revealed that he was the mistery gunman who penetrated high-security defenses of the Vudu Lounge and injected viral gay nigger seed deep inside the Olsen Twins, was indeed a full-time GNAA member.
"This is serious," rkz began. This is a first event of such magnitude since GNAA opened its doors to new members in 1996. Until now, we were gathering new members by announcing our group information on a popular troll website, slashdot.org, but this is a whole new era. By injecting our holy gay nigger seed right into human females, we will be able to immediately collect thousands of members. "Make the most of the next six weeks," he added. "We will grow in numbers more than you can possibly imagine".
Insertion of the GNAA collecting penis into their tight little vaginas came right between the consideration of Justin Timberlake to buy out the entire early saturday morning disney entertainment show's cast, and will most likely positively affect the decision. By adding all the gay niggers working for Timberlake with the gay niggers developing Mac OS X kernel source, GNAA will be all-powerful and will begin plotting our next plans to penetrate "backdoors" into the next favorite teen pop star Kelly Osborne.

Re:Java?
Most of your points have been addressed, but I think this one has not:
Although Java is a little bit nicer than C++, one error Java programmers often do is that they forget to assign null to pointers. This has a big consequence: the virtual machine does not free unused objects as soon as possible.
You don't need to set variables to null to have them garbage collected. In fact, sometimes it's a bad idea.

People's Republic of California: power cords> # Offtopic, Inflammatory, Inappropriate, Illegal, or Offensive comments might be moderated.
I always read that as:
# Offtopic, Inflammatory, Inappropriate, Illegal, or Offensive comments might be moderated +5
Dumbest warnings I ever saw were on a laptop's power supply:
FOR USERS IN CALIFORNIA:
And no, I'm not making this up.WARNING: The power cord on this product contains lead, a chemical known to the State of California to cause cancer, and birth defects or other reproductive harm. Wash hands after handling.
Of course, there's no word on whether the lead in the power cord is transmuted to gold when I cross the border into Nevada, or whether or not residents of other states need to wash their hands after plugging things in or not.
(The background is that a bunch of twits fell for the junk science on PVC softened with lead phthalates. Consider that if studies on intravenous bags with the stuff are questionable, it's Not Bloody Likely that failing to wash your hands after you plug in your laptop is going to kill you. But since when did science matter to the granola-crunchin' hypesters of the People's Republic of California? It's to protect the chilllllldren and the enviiiiiiirunmennnnnt!

Re:Any neural net people here?
I've been curious if there has been a hyperelegant neural network solution that can do everything from recognize handwriting to faces. [...] Are there any real (not patent or such) related reasons this doesn't exist?
Aside from the fact that about a third of the brain (if I remember correctly) is dedicated to visual processing and that the brain has a hundred billion neurons, each neuron firing at up to 1KHz and with thousands of connections to other neurons? :)
It's an enourmously complex task to be able to do this reliably. Recognizing a straight-on photograph and matching it up with a corresponding mugshot is a whole lot different than seeing the side of a person's half-shadowed face from slightly behind them and recognizing that as the same Alice who held up the convenience store on Tuesday.
Handwriting recognition is orders of magnitude easier to do, since it's a lot easier to recognize similarities between a sample of writing and previously analyzed samples. In fact, there's a lot of research into this already. Facial recognition is slowly getting there, but people are still stumbling over the same mistakes that were made decades ago -- attempting to formalize facial recognition by defining a set of rules and matching to those rules. Much like spam filtering, this works to a degree until the differences between the one you want and the one you don't no longer fits within the rules.
Neural net + genetic algorithms/programming to refine the net's connections and behavior is probably a good approach. Finding a means of populating, storing, and computing hundreds of billions of nodes in the network is the real challenge I think. Of course, take everything I've said with a huge grain of salt as this is a subject I'm fascinated by but have little practical experience with. -

Re:Your Bluetooth desktop?
But what happens when I set it next to two or three computers?
Put a NAS frontend on it and let clients mount it. A little too "enterprisey" for the hobby crowd I know, but a solution nonetheless. Instead of saving up to buy one of these, I could just put a hard disk somewhere in my computer room and have clients map the drive space. Also comes in handy during those pesky FBI raids when your data drives are actually installed in the attic or inside the walls themselves. -
Re:Broken link, java jab
Regarding #3, that is not generally true. Check out Brian Goetz's article, where he points out:
Object pooling is a straightforward concept -- maintain a pool of frequently used objects and grab one from the pool instead of creating a new one whenever needed. The theory is that pooling spreads out the allocation costs over many more uses. When the object creation cost is high, such as with database connections or threads, or the pooled object represents a limited and costly resource, such as with database connections, this makes sense. However, the number of situations where these conditions apply is fairly small.
In addition, object pooling has some serious downsides. Because the object pool is generally shared across all threads, allocation from the object pool can be a synchronization bottleneck. Pooling also forces you to manage deallocation explicitly, which reintroduces the risks of dangling pointers. Also, the pool size must be properly tuned to get the desired performance result. If it is too small, it will not prevent allocation; and if it is too large, resources that could get reclaimed will instead sit idle in the pool. By tying up memory that could be reclaimed, the use of object pools places additional pressure on the garbage collector. Writing an effective pool implementation is not simple.
In his "Performance Myths Exposed" talk at JavaOne 2003 (see Resources), Dr. Cliff Click offered concrete benchmarking data showing that object pooling is a performance loss for all but the most heavyweight objects on modern JVMs. Add in the serialization of allocation and the dangling-pointer risks, and it's clear that pooling should be avoided in all but the most extreme cases.

Re:Can you multithread your application?
What Cray's rightfully pointing out is that for most business applications, however, distributed computing is not a viable option. When processing on a transaction basis, the transactions often need to posted in the exact order they were recieved, which means they must be taken serially.
The veracity of that depends on a few things, including whether or not the database behind the app is single- or multi-threaded. For a database like Universe, performance running on a cluster wouldn't differ all that much from performance on an IBM or Sun or HP risc box of the same processing power. The downside of multi-threaded databases is that, aside from dealing with a sharp increase in the number of users, you cannot make aggregate processing any faster by adding CPU's, you have to add memory, or move to faster buses or faster CPU's.
The cluster isn't the solution to everything. Nor is the supercomputer. You've gotta think about the job, then figure out which tool is right for the task.
It's all a trade-off of one sort or another, and yes, you have to have the right tool for the situation at hand. But let's not forget that there are a variety of non-traditional solutions for traditional situations that often result in a much lower Total Cost of Ownership. We don't read more about these, in part, because it's not in Vendors' best interests for us to do so. -
Re:Just because we love Linux....As far as I know if you're deploying a large database it's still advisable to have a big huge IBM mainframe or a Unisys box or a Sun 10k instead of 4,8 or 16 clustered 8 proc machines.
nitpick: These are also not generally considered HPC.
But anyways, where do you draw the cutoff? Would you consider something like this an HPC or an HPCCC? Technically, that's an HPCCC, but I don't see how you could really call it anything but HPC. Clusters (with a good interconnect) are every bit as HPC as Cray.
Now, that doesn't meant that they're always better. There are still jobs that a Cray is more appropriate for, but for a large number of HPC jobs, clusters are very appropriate (and cost-beneficial).TZ

Re:Uhh... IBM's had a Pervasive Computing Lab...
I agree. The article (not the slashdot post) seems quite 'arrogant'. Pervasive computing has been around for about 25 years now (also overlapping with ubiquitous computing).

Re:Python's dirty little secret
It is clear you do not know anything about Python. You are not a long-time Python developer but rather a troll. The first hint is that you misspell Guido Van Rossum's name.
The second hint is that you cite a page from 1999. A Python developer would know that that was before Python had cyclic garbage collection. Here is an article from 2001 that describes how the issue was fixed.
The third hint is that you point to a page that describes how to avoid creating a memory leak by appending an infinite number of items to a list. Guess what: appending an infinite number of items to a list causes a memory leak in Java, C++, C, assembly, Scheme, sh, Perl and every other programming language in the world. If you ask the computer to store a continually growing list of items, it will do so...in any language.
If you think that Python can leak memory in circumstances where other languages would not, post an example program and we'll all test it out. -

Aha!There's the long-awaited IBM G5 blade server! I knew it was coming, and now it's here.
Specs, as stated on IBM's page:
Modular blade server optimized for the BladeCenter enclosure
Two PowerPC® 970 processors at up to 1.6GHz standard
512MB standard/4GB max PC2700 ECC DDR memory
Up to two IDE hard disk drives for 80GB maximum internal storage
Two Gigabit Ethernet controllers standard with load balancing and failover features
$2,699How disappointing. For the sake of perspective, here's the Xserve G5 Cluster Node:
Dual 2GHz PowerPC G5
512MB DDR400 ECC SDRAM
80GB Serial ATA drive
Mac OS X Server (10 Client)
Dual Gigabit Ethernet
$2,999OK, so the IBM server is slightly cheaper. But look what you get:
slower processors: 1.6 GHz vs. 2.0 GHz
slower memory: 333MHz vs. 400MHz
slower storage: ATA-100 vs. SATA
no storage in the standard model: 0 GB vs. 80 GB
less expandable storage: 80 GB vs. 750 GB
less expandable memory: 4 GB vs. 8 GB
That being the case, I'd say this is a disappointing product. Why would anyone choose it over the Xserve?

It's free. IBM has a program for Linux developers who wish to test their application(s) on a genuine mainframe. You get a free z/VM-hosted Linux image for 30 days.
Which gives an idea of how many concurrent VMs mainframes can handle (and at what cost if IBM is giving them away to developers). Note that you have the whole image, root login and all. -
Try the IBM Journal of R&D
There's a pretty good zArchitecture summary here describing the RAS (Reliability, Availability, Serviceability) aspects of the z900. Be sure to back up and visit the G5/G6 RAS features (linked in the article), because those still apply. Note that the z990 added a couple new RAS features.
This journal article mentions something called Parallel Sysplex, and it's worth highlighting. Very interesting stuff, that. -
Re:CICS sounds similar to Unisys TIP and HVTIP...
TIP is probably closest to TPF.
IBM went toe-to-toe with Sperry and Burroughs (now Unisys) and beat them in most markets. The companies fought to a draw with the airlines, with Sperry and IBM roughly splitting the market. (I think Burroughs was stronger in banking and finance.) Unisys still has some customers, still running TIP, still on ClearPath mainframes.
