Internal colo networking is mostly copper. Fiber-copper converters are used only for external telco links and only when absolutely needed. Why would you have extra piece of equipment sitting in the rack and degrading your reliablity?
I have switched to C++ exactly because overloaded operators allowed me to program transformation in parametric domain (think Fourier) in a natural way, like C = B*A. That's instead pascal's C=mult(A,B). Now imagine what D=(A*A+(C-F))/L wood look like if written with explicit functions and I'm sure you'll get the point.
LSE is not even big comparing to US equity markets. I would even say small. Their data flow is about one tenth of that of Nasdaq. The number of traded issues is a tiny fraction of number of US issues too. And yet they have absolutely horrible latencies of order entry interfaces comparing to what's 'normal' for US electronic trading venues. Their TradElect platform even lacks proper timestamps on Level2 market data messages. On top of that wire format description is afair ~700 pages long. Compare it to Nasdaq spec - 12 (used to be 4) pages for market data interface, about 20 for order entry. It's clear that LSE is one tangled mess - and the reason for it was a monopoly on trading British names and other listed securities. Now with MiFid EU directive in place they do not longer have that cushion. So do not blame Windows - blame inept management and their boneheaded decisions.
I'm surprised no one mentioned that platform yet. Take GumstixVX main board, BreakoutVX IO board that has bluetooth and IO pins, mount it on stock RC heli and connect gyros to the IO pins instead of standard receiver. You then got a test platform for under $500. And yes, it does run Linux. If you want, GPS and WiFi cards also available. You also can connect off the shelf accelerometer to it.
I've converted ESky Honey Bee 2 microheli to be remotely controlled from a laptop and ti's been a lot of fun.
"UDP lets you send non-linear messages of arbitrary size without delimiters." - as long as it does not exceed MTU, which is insufficient for a lot of apps. To combat that problem people built reliability layer on top or UDP (RMCAST etc) and end up reinventing TCP, poorly.
Having to serialize data structures into byte stream is a problem, though, that I fully agree with. But what is the other option?
You must be working for quite non-demanding employers all those 20 years. Let me guess, huge corporation, 10 level below CEO? In my line of work it's common to let under-performing programmers go. Few places even go to extreme with bell curves and 360 reports. Still there is no shortage of applicants - the work is challenging and pay is excellent. Actually finding out good people in the sea of mediocrity is tough part of the job.
From what I can grab between the lines the guy (Ponomaryov) wants to get a piece of russian bailout pie under pretext of creating "national os." This same line was played many times before in Russia, Ukraine, and China (Red Flag Linux.) Apparently Ponomaryov lacks connections with right officials so he does not know whom to bribe. That explains "lack of interest" from the ministry quite perfectly. If he eventually finds a bureaucrat who takes the kickback at best he would release CentOS with Russian as default language and modified splash screens featuring russian tricolor. At worst they would embark on translating bash to use Russian words for commands (PDP-11 translated and branded RafOS comes to mind.)
Including 30+ production servers. Love it for the driver support and all latest packages. Had very few problems over the course of 6+ years, mostly with packages broken upstream. Looked on few occasions at Fedora and Ubuntu but always came back. As for desktops, PLF (non-free codecs and libs like libdvdcss2) is a real kicker.
Just glorified accounting. So find something real to study during your post-grad years. That said, actually making money trading in many circumstances requires solid mathematical background and disciplined application of scientific method. The other alternatives are being a member of old boys club or go Madoff style.
Trading 'from the gutts' now is just asking to be ripped of by robots.
"And You? Where do you want to go today?" - me is going to insanely expensive restaurant to spend a fraction of profits made today using Linux and console apps.

Being former H1B holder myself I believe that on average the program is benefiting U.S. Sure, there are well known problems but the program largely fulfills it's purpose - to bring smart and energetic young people to America (unlike visitor visa H1B DOES imply immigration intent.) Think of billions saved on their education for starters.
However some big outsourcing companies have been subverting the program for years. They fill tens of thousand application only to bring their overseas employees temporarily, pick up brains and send them back after a year or two. Not only this violates spirit of H1B program but also denies other businesses a chance to hire overseas talent. That's what in fact brought about recent student visa extension.
P.S. Europe currently getting close to cloning H1B with their "Blue card" program. Probably because H1B suck so much? ?-/
They are only entertainers after all.
Uncontrolled greed of CxOs and mortgage brokers, focus on quarterly bonus instead of long-term business success - that's where roots of CDO/CDS debacle lies.
SEC tried to indirectly blame equity market participants by banning 'short-sellers' - and learned it fast that speculators reduce market volatility, not increase it. At least SEC had guts to acknowledge that by not extending short-sell ban further or not going back to tick-test (which previously was proven to have no impact whatsoever).

I've been using Mandriva since 2002 and never had a reason to go back. Right now I have it up and running on more than 20 desktops and servers, more than half of those running critical business apps (like in millions of dollars). Beside being an able server distro (with appropriate version of kernel loaded) it makes for a great desktop - just google for PLF.

What's really pitiful, LSE has just a fraction of data/trade volume of major US exchanges like Nasdaq or NYSE and still, their systems are regularly getting hosed, albeit not as much as today's meltdown.
Hopefully in coming years LSE will lose market share to Nasdaq/Europe, BATS/Europe, Chi-X and other electronic markets - that should teach them well.

You do not need to go on template circlejerk fest for 10 weeks every so often. Reading few books once would suffice.

Wake me up when MS rewrites windows in C#. Or Sun/Oracle releases JVM written in Java. I refuse to eat their dogfood until vendors do the same.
Cause one thing C++ sure doesn't have is enough features, right?
Some of us do not equal C++ to C with classes.
Every job that can be replaced by script (automation) should be replaced by one. This is how people grow productivity since stone age.

Nothing wrong, except one you mentioned does not exist anymore, another is merged with Euronext and renamed itself and new market places popping up and taking double digit volume percentages. Three markets are thing of past long gone so your initial statement is very far from reality. But otherwise I agree, nothing is wrong with stock markets per se.

Stick to your modern languages kidz, don't spoil the party B-)
A lot of people are talking here about "they can fire you at any time". Well, that cuts both ways: you can fire your employer at any time as well.
It's not easy to find _competent_ people, so they stand to loose as much as you if not more.
Keep your options open, hunt around and do not allow yourself feel bad about your job. It's better for your long-term health and self-esteem.
