Re: The problem isn't C
Yawn. 2005 called and wants it's performance-based objection to Java back.
Choosing performance over correctness is what got us here in the first place, no?
Re: The problem isn't C
Sorry, I am struggling to see how this could happen in Java. Really. There is no way (*), in a correctly functioning virtual machine, for a byte array to contain uninitialized data (or, rather, data from elsewhere in the heap). You would get zeros, an ArrayIndexOutOfBoundsException, or it would fail to compile.
* Excluding native code malarky, but then it's not really Java.
"... their feelings of inadequacy as parents by telling the rest of us what we can or cannot do..."
I'm afraid you do't need Mumsnet for that - the moment you have one child, you automatically get enough knowledge to advise anyone else on theirs. Sometimes it even works if your sister/colleague/neighbour has a child too, it's that powerful.
"one to one relationships and one to many relationships and many to many relationships"
Gosh, that does sound complicated. I simply can't imagine how you could represent that in SQL.
If your first sentence isn't QOTW I will despair. Excellent summation.
Several problems with this article
Although I agree the Tobin tax is a very, very good idea.
First, you haven't touched on one of the main issues described in ther NYT article which is the banks opaquely trading in their own "dark pool" before releasing the order to open market, something which wouldn't be possible without HFT. This strikes me as pretty important.
Secondly, the front running issue isn't a "bit naughty", it completely undermines your second argument which is that the reduction in spread resulting from HFT is good for the market - perfect information, flat market, good for everyone. Frontrunning doesn't flatten the market, it distorts it, and like naked shorting should be illegal IMHO.
Any finally, your HFT providing the flat market is an economist utopian ideal which doesn't exist. In the real world the banks making the market are also playing the market - the game is rigged, and tools like HFT, insider trading (did someone earlier really suggest this should be legalized? really?) and the "POS" attitude by the banks mean that this perfect information is not available to the market. It's available only to the banks, who profit, at the expense of their customers, who lose.
All of this comes down to your idea that an unfettered market is a good thing, which I flat out disagree with and cite... well, large chunks of the last 100 years as evidence.
Heard of this happening many times. The switch to alternative medicine is always doing wonders for them and they feel much better right up until they drop dead, sometimes from a curable illness. It would be funny if it didn't happen to real people.
Gotta love Apple
Judge for yourself, here's the Unicode reference for the "Emoticons" range - horrors, there is one.
Not seeing a lot of colour in those sample images, and not seeing a lot of racial profiling in the descriptions either - for example, U+1F60D is described as "FACE SAVOURING DELICIOUS FOOD", not "WHITE MALE FACE SAVOURING DELICIOUS AND INHERENTLY SUPERIOR NON-ASIAN FOOD AFTER CONQUERING AN INFERIOR PEOPLE AND TAKING THEIR OIL". Probably an emoticon you'd use a lot of.
Perhaps they're still smarting from having their Apple logo banished to the private use area, or worse.
Colour me U+1F632.
Re: Wet fart while she was spooning worked for me...
Come back amanfrommars, all is forgiven.
Re: Java on the desktop is dead
Applets? Maybe, but not for much longer. And I say this as someone who develops them - I can not in good conscience recommend them to my clients any more, as we can't guarantee they'll run from one release to the next due to unpredictable changes in the security model. Applets are dead.
Re: Another interesting hypothesis
Completely obliterated? What do you think hit it, the Death Star?
And in related news
The average life expectancy of a contributer to the BBC's "Have You Say" comments section was reported as 48. Only slightly higher than their average IQ.
For that effort alone BBC3 should be lauded to the heavens for all eternity.
Mongrels was also a gem, although boo for axing it. Yes, I watched season 2. It was still good.
Re: Ah yes, Colbert. Another unfunny guy.
Old skeletons? The citizens of at least Bangladesh, Indonesia and Chile would disagree with you. Although to be fair there are rather a lot of old skeletons as a result of his, er, diplomatic efforts.
No, blowhard, a thousand times no to your Terrorism idea.
There's too much shit categorised as terrorism already - going to protests, carrying bags, wearing coats in summer, being irish/asian depending on the decade. The police have more powers under the prevention of terrorism act, so suddenly everything is a possible terrorist act. I'd like to see LESS stuff categorised as terrorism. Shoot someone while shouting something political? It's murder. Don't let them dress it up in a cause.
Anyway, using your argument, as you're clearly damaging the economic output of the country why not just go the whole hog and call it treason?
That LRB piece is a fantastic read
Well worth it.
Re: Yes we know you...
Given our recent behaviour, I'd be surprised if the UK was invited to join any pan-european data warehouse...
Re: "we were able to make a live demo of Computrace hijacking"
+1 for that link, it's a good read and hard not to find for Kaspersky. It's clearly vulnerable to an arp or DNS poisoning attack. And WTF is up with the obfuscation, given it's apparently installed willingly by its users?
Don't encourage them
You underestimate NMEA0183. It's ubiquitous, simple to implement, easy to parse, is not necessarily limited to 4800bps (some devices can be switched to 38400, easily giving you 10hz position updates), requires a minimum of one data line (plus ground) to connect and although originally a closed standard has been reverse engineered so everyone can play with it. Some of the sentences are a bit clunky, but so what? Show me a 20 year old protocol that isn't.
The replacement (at least for marine use) is NMEA2000, which is a binary protocol based on CANbus, requires particularly expensive cabling and equipment to use and the purchase of the specification to implement. Google CANbus-usb converters, there aren't many.
As for battery life magically draining when your GPS is on, typical power draw for a GPS receiver is 20mA. Oh noes, GPS is eating my batteriez!!!1!!!!
Re: It's a good idea, but...
And that's not how it's done. I know someone that does this (in NZ) and the process involves many small devices positioned around the site, which have their strength/position adjusted so that they're blocking just enough and not interfering with the area outside the prison. That's the theory, anyway.
Re: Can you say "sample bias"?
This article is a summary of a study, not the whole study. The errors bars on the graph indicate that it's a small sample, but it still looks statistically significant to me. For the rest of your questions you could, you know, read the study itself.
XBee have a range of piddly little chips that can allegedly get that sort of range. Yes they need an antenna to do so, but I imagine you could piggyback on to the wireless antenna - you've got physical access already, right? As for RF, sure it would be if you're looking for RF. So set the device to only transmit when the laptop is at the owners home, not when it's in the TEMPEST protected room at the office.
And USB devices can present themselves as multiple devices - they can mimic a hub, for example, or they can can present themselves as a dual keyboard-and-disk if they want to. If that disk has an autorun script which immediately unmounts itself, you'd never notice it was there.
I totally agree a bit of scepticism isn't unwarranted here, but technically it's quite possible.
Re: A lot of bored/dissapointed people out there @Tom Welsh
Tom Welsh, you're veering into David Irving level bullshit. There's no requirement to "praise the jews", a ridiculous statement - how is this diktat enforced, pray tell? Two minutes of cheering every day after breakfast or 30 days reeducation? There is a requirement not to glorify the Nazis, not unreasonable given their history and I think you'll find the rest of Europe had no problem with this policy in 1945.
Free speech is not the ne plus ultra of human rights, not in any country even your (presumed, I think safely) native US. Google fire in crowded theatre if you have trouble with this concept.
Re: Psion - "an arrogant bunch of tossers"
I chortled to myself when I saw that quote attributed to Alan Sugar. Sweet irony.
Graham the blind squirrel finds a nut...
Graham, you've got some odd opinions.
RC6 is not proprietary, it's algorithm is public. It's even on Wikipedia. Encryption can be applied to UDP or TCP equally, and in fact a block cipher lends itself fairly easily to UDP - although I have to admit UDP is an odd choice, as the strength of a block cipher comes from block chaining which isn't viable with UDP (lose one packet in the middle and you lose the ability to decrypt the rest). How amusing if the NSA were not doing this, intercept enough of their traffic and search for a plaintext crib and you could find their key...
Identifying a UDP packet encrypted with RC6 is not easily detectable: it is, in fact, impossible on the wire, as it will look like a packet with noise in it. Because of the encryption, you see. Identifying the cipher used to create the noise is statistically impossible for any well functioning cipher, almost by definiton really. To identify the use of RC6 you would need to disassemble the code generating the packets and identify the algorithm by it's "footprint".
However in all your bluster you've asked one very interesting question: if you're tapping an undersea fibre to copy all the data, where do you route this data? On the same fibre? This implies complicity from the backbone provider, and in that case why bother to hack it in the first place? Or do they lay another cable out?
I have seen a lot of shit cloaked in class hierarchies and inheritance.
As for HTML & JS, I'm not saying I'd write a kernel in it but when done well it's unparalled for rapid development (and ease of deployment) of UI. Horses for courses.
Re: Interesting POV.
For avoiding bank fees on international transactions I have to recommend CurrencyFair - no affiliation but a very satisfied customer, and if I have any complaints it's that they didn't exist a few years ago. I've have saved a small fortune in shit bank fees and considerably shitter exchange rates.
Re: But how long until TOR is made illegal?
A more interesting question is how long until someone running a Tor router is prosecuted for distributing $BANNED for something passing through their hardware?
Re: Its all about the drugs
I'm sorry, but what? Do you mean molecular assembly, as seen on Star Trek? Or is there a condition that's cured by consuming coloured plastic?
If you're sober enough to remember to do that, you don't need to do it.
Re: Image hash database
I would imagine that's very unlikely - a sysadmin finds a file matching the hash, does he a) report it to the police and watch machine he manages get confiscated, or b) delete it because "Timmy isn't that sort of chap, must have downloaded by accident".
Another +1 from me, a good read.
Re: Over excitement much?
Apple? Feck! Arse!! No wait, it's about extrasolar planets. Back to sleep, Eliz.
(Jesus, a car analogy already. Hello, Slashdot)
Many familes have a car too, but a 12-yo with a vague inclination towards mechanics isn't going to disassemble it to see how it works: it's too expensive, and the family need it to be in running condition. But give said 12-yo a beat-up old 1960's mini and express permission to tinker, and in ten years you might have a skilled mechanic (*). I know a few people who've done just that.
Yes there's plenty of hype (from third parties), but I still don't see many articles that say "this will spawn a generation of programmers". However I think "this might spawn a generation of programmers" is accurate, especially given the opportunity for most kids to learn these skills in ICT at school or on the family desktop at home was pretty much zero. So it's undeniably an improvement.
The difference between a computer and a computer you have permission to destroy and rebuild is quite a big one.
(*) there are other possiblities too...
Re: A little more back ground (What no anti-fox protests?)
That's it people: irony, it's officially finished. It's over. Nothing can beat "A lot of us listen to fox because we are more likely to get information instead of bombast."
Hooray, another person who things it's someone elses responsibility to keep them safe. How about a bit of personal responsibility AC?
It's not like they're saying "don't go outside, you may be shot by a sniper in a random act of violence". They're showing you (well, trying - I can't ge the video either) how to use your own initiative to prevent a crime from occurring. How can you possibly have a problem with that?
Re: Even Win 7 is iffy
Have a downvote for not knowing your old-school memes. You'll be saying the plural of Vax isn't Vaxen next.
Re: Intel didn't seem to know what they were building
"The recommended output rating of the power adapter is 5V, 3 Amp." - from http://www.intel.com/support/galileo/faq.htm
I'm aware that what it draws is - usually - likely less than 3A, but in my experience if you design a system that supplys 500mA to a device that the manufacturer recommends should be given 3A, you're in for a nasty ride.
Re: Intel didn't seem to know what they were building
Oh, and it needs 3 amps! I don't know what does the equivalent Arduino Due uses, but the Beaglebone Black is under 1A and the Arduino-alikes I use (Atmega or Arm based) are all about 25mA excluding I/O.
Proof, if you needed it, that Intel don't do embedded well.
Re: Nothing will make airships viable.
This lot disagree with you, and so presumably do their main clients, the US Miltary:
My mates working for them - pretty impressive stuff, from what I've seen.
Slightly fruity comparison
I have to point out that for your banana analogy to be correct, the entire world's banana consumption would need to take place in a half-acre block. Suddenly this doesn't sound so safe, and not least from a biohazard point of view. Plus the fruit flies would be unbelivable.
Re: I swear
You really stop reading when you see the word "misogyny"? How did you write the second part of your comment? Did you close your eyes? I suppose it would explain why you misspelt "women".
Re: all-in-one iMac
What is this "DVD/CD" of which you speak? Is that, like, vinyl or something?
Lies! Damn lies!
I'll give you two feeds - one of random data, the other an AES256 encrypted stream of bytes from an initialization vector only I know. Lets see if you can tell them apart.

Re: My 3M wi-fi thermostat doesn't do ANY authentication at all.
Given the bulb has to be on the wireless network, I kind of wondered why they bothered?
Instead of half-arsed security that was always going to be broken and which certainly took them non-zero effort to create, why not just take out the security altogether and add a warning to "secure your network properly". Passes the buck neatly passed to the homeowner, it's less expensive for Philips, and it would have saved them a bad headline.
Re: Microsoft FAIL
Ironically WIndows 95 (which was the fashion at the time) was never vulnerable to the Ping Of Death - it was mainly big iron. Don't recall the details on Windows NT, I think it was OK as well.
