"I can see doing trades in baskets of orders entered in say 60 second intervals and processed in random order inside the interval. That prevents a class system where guys with access to HFT have a shot at the getting in or out first all the time and moves it to where anyone with an Internet connection, a E-trade account, and a willingness to sit with three or four of the major news networks on a few tvs has a fair chance of transacting on whatever securities they are playing as quickly as anyone else. That seems okay."

Except anyone (human) won't submit 1000's of small trades to even the odds. You put a trade for 100 shares in as well as 99 other people buying ~100 - it's fair. My (previously used for HFT) computer submits 1000 lots of 25. Suddenly I might not get the full 100, I need to start cancelling when I get my quota, but I'm more likely to get my 100. If the computer plays it right, it could adjust the purchase quantity against projected movements. Add 1000 previously employed HF traders doing the same. Humans have a nigh-on impossible chance of getting a single trade, infact we'll end up in the same situation we're in now, where a large chunk of small trades are machines competing against machines.

Personally, I'm all for a 60sec hold before being able to sell. Give people a chance.

Screw trains. Tell us why American cars' petrol tanks explode when all four tyres leave the ground...

Is it static, do you need one of those rubber strips hanging off every car? Should they be a requirement for police vehicles, especially?

It must be true, I see it on TV *ALL* the time!!!

No. We logged for investigation later.

We are talking about being able to either prove the student wasn't at that site, or provide evidence the site was visited for the school pastoral care staff to follow up.
Without monitoring, going back and determining a case one way or another is nigh on impossible.

Lastly, these are minors. There are government obligations to report illegal activities in school. Like proving a teacher was browsing porn on the school network.
"Think of the children" has a lot of traction with governments...

a) "we have not signed anything which would excuse it" - you can't. You're not able to sign enforceable legal documents.

b) "there was a root CA from the school" - it happens due to
        1) WPA-Enterprise and/or NAC relies on keys. Do you use your school credentials for wireless? If so, you require key exchange for it to verify each party.
        2) SSL monitoring systems rely on MITM to read the HOST headers. We couldn't give a rat's arse your bragging about banging Sally, however we do mind that it was to a website called HTTPS:// and both Sally and yourself are under legal age, it may have included a phone camera image, and it was all posted via the School Internet. Federal, State, and School pastoral care policy issues trump most whiny students objections.

c) It happens when at the start of the year. I would have twenty staff ask for different packages to be deployed in the first week of school, and your BYOD package may just happened to end up with a testing cert. Once had an antivirus package that hid all toolbars in Word and Excel - that ex-employee never applied a GPO at domain-level again.

All I'm saying is most school IT departments are asked to perform miracles of pastoral care because parents don't care and Teachers are busy trying to teach. We bare the brunt of school administration trying to enforce pastoral care not just for you, but all those in the school body
I'm sure if you had brought it to most IT departments attention in a courteous way, you might have been treated better.
Most schools have a tech-savvy student who is treated like an offsider, as well as one who has joined the Dark Side and ends up on the Watchlist. (yes, I've had "meetings" with Federal Police over a student's actions). Which one will you be?

The other downside is that strong radio transmissions can interfere with things including speakers, which might make them obvious if not handled correctly.

And people complain about the CirrusLogic and RealTek on-board audio buzzing because of bad grounding... Maybe the buzz isn't grounding at all...

I honestly don't know of any decent AQL optimisers...

I know MS SQL Management Studio has SQL Profiler, Index Tuning Advisor, and Database Performance Tuning Advisor.
But there's nothing in Aqua Data Studio that works with PostgreSQL, which means co-workers and I must rely on good looks and mad skillz (I'm only passable on both)

Besides datasets not fitting in to GPGPU memory, and I/O bottlenecks, I'm still seeing plenty of badly written SQL

A current contract has plenty of SQL work (not for me though), and the bulk of their time is cleaning up data exceptions, badly written report queries, and moving oft-used or large-dataset queries to stored procedures. GPGPU's will hide some of the rot, but if the SQL was written better in the first place, we're able to use parallelism and better use existing commodity hardware in clients virtualised environments.

I'm not dissing the prospect of GPU acceleration, just the priority TFA gives to it.

No. The backing companies promised not to use the patents this way, and then washed their hands when Rockstar said "well we didn't promise anything..."

They're a corporate hitman, giving the backers plausible deniability and no surface area to countersue (since they can't infringe anyone else's patents when they don't make stuff)

We've worked on minimal hardware routers and iptables can't keep up with pF on the same hardware.
pF also allows more flexibility, and can do funkier layer 2 than iptables.
The ALiX boards in the Yawarras ( are small, flexible, and FreeBSD supported.
We don't use them so much anymore since we run more VM host-based firewalls, and we've moved on from hosting various physical machines requiring firewalling between them (since a possibly compromised machine's firewall can't be trusted...)
