RC4 crypto: Get RID of it already, say boffins

Re: WPA or WPA2?

Sounds like another scare story. While any encryption can be broken given enough time and sample data, the question really is: is it good enough to get the job done to an adequate level of security ?. For example, network stumbler here reports 20 to 30 ap's within range, most running wpa2, probably many hundreds just on this estate. To crack even one of those would take a very determined and knowledgeable hacker a considerable amount of time and for what gain ?. Streamed Coronation Street doesn't cut it. For any hacker with malicious intent, the balance is always how valuable is the data, or, gain vs effort. For most, other than as an intellectual exercise, it's really not worth the effort.

Only government agencies have the resources to do this and there are probably millions of wifi setups across the uk, so it's a big haystack and they would need good reason to want to do it in the first place. Afaics, they are welcome :-)...

Reg man inhales the smooth, non-cancerous, taste of USB nicotine

Re: Been using e-cigs since June

Agreed, I bought a starter kit last December (Jac Vapor) after doing the research and haven't smoked tobacco since. I was smoking 6 or 7 a day previously, years ago, a pack a day, but it was affecting health and lung function. The thing smokers have to understand is that it's not just the drug, but other factors, such as something to do with the hands, oral stimulation and social. Anyway, haven't convinced my other half yet, but feel no temptation at all to smoke cigs, even in the same room as a smoker. Better sense of smell, taste and stamina + save a load of money are good enough reasons for me, not to mention decreased risk of serious disease.

Study: Arctic warming at 'stunning' rate – highest temps in 44,000 years

Re: I'm Sorry

As a child, I regularly used to watch my grandfather up north eating tripe every Saturday, with raw onions and malt, not wine venegar, but I never liked either the texture, or the taste, though it is supposed to be very good for you :-). And, we were discussing energy, not all the peripheral green stuff, but even that isn't space technology, though there may have been a few spinoffs.

As for batteries, there is a lot of research and progress, but again no free lunch. You have to take into account the cost / energy use of extraction of raw materials, processing, manufacturing, limited lifetime and disposal, much of which is bad for the environment.

Anyway, rather than comment something rational, you throw toys out of the cot, diss and have a sulky ?. How can I take that seriously ?...

Re: I'm Sorry

Overall efficiency also includes the cost of manaufacturing the item, installation, maintenance and expected life time, as well as the the efficiency of generation.. Solar would be a great idea if it were cheaper, but at present, if you cover you roof with solar panels, in the uk, it will take 10 to 15 years to recoup that investment in terms of energy generated, though it may give you a nice warm green feeling. Also, panels don't have an indefinate life. 15-20 years is typical, from figures i've seen, so just at the point where you've paid for them, they need replacement. As for wind farms out at sea (nimbys don't want to see them in nice parts of the landscape where there *is* loads of wind), the initial costs are astronomical and the salt atmosphere means that they need regular, expensive (as in difficult to access) maintenace.

No free lunch i'm afraid and nuclear is the only relaistic option at present...

Are 2 places I check out regularly, but GOOGLE is a choice.....

That's very patronisingly good of you to suggest, but having done electronic design for a wortking life, software engineering since the late 1970's and mechanics / physics out of interest, I really ought to have some sort of clue. All I can say is that if the above two links above are the sort of places you go for scientific info, then i.m afraid you will end up misinformed. Most web sources are pretty lightweight in terns of fact, no depth etc and you have to go to specialist journals and websites to get the real picture. Still, all is surfaces and 2 minute attention spans on the web / social media, isn't it ?.

"What is high tech about solar panels, wind turbines, Low Power Associated electrical control, lights/appliances, most coming from developments in Space Industry ?, Systems used in Hydroponics, ( cause we be growing food indoors, soon ), Systems for Water, (because that’s what we may be doomed to fight over ...) Cheap Relocatable housing, may be a boom industry, as people may need to move to avoid issues, but they always do."

Absolute tripe. Sorry, 90% is just run of the mill electronics and engineering. While stuff like wind turbine blade design may have benefitted from aerospace practice, there's little else afaics. Space engineering ?, hilarious, you msut be kidding. :-)...

Re: I'm Sorry

"WHY is everyone thinking a green future is low tech, green is high tech"..

That's debatable, as neither solar or wind are particularly high tech. The conversion efficiencies are dismally low and they both very high upfront capital investment. The only one that is high tech is nuclear, but we have had that working safely in the uk since the 1950's, in case anyone has forgotten.

Perhaps if we got really serious and spent a lot more money on fusion research, we would have a workable solution that really would tick all the boxes.

Ok, so what do you see as high tech in relation to green ?...

I wouldn't take New Scientist too seriously either, unless you like pop science articles with gross errors of fact It used to be a good read and we (family) subscribed to it for years, but it just became too sloppy to take seriously.

Science is about questioning everything, especially the things you respect and trust the most, but i'm sure you know this already :-)...

Re: greenies are wrong about almost everything

BlueGreen,

There's so much virulent controversy over this issue, even after decades of research, from those on both sides of the argument. It suggests that the issue is far from resolved in scientific terms. After the initial hysteria and knee jerk response from governments, the pendulum at last seems to be swinging back to a more reasoned response and not before time. I'm all for renewable energy and even started a project for a small heat and power plant (chp) over 15 years ago, but the tco and general economics didn't make sense then and doubt that they would now. Same goes for solar and wind, which could never be reliable enough to provide base load for the grid. Now, i'm just skeptical about the whole issue. It's been done to death, headless chickens, at vast expense, with still no conclusive evidence that: we are on the edge of some kind of environmental disaster.

All the stiudies and controversy seem to suggest that even if there is warming, the signal is so far down in the noise that in engineering terms, it's unrecoverable and the statistical methods used to recover it can be tweaked to show anything you like. ie: not enough data and thus not real science, imho....

Re: Easter Is

Ok, but that still doesn't show or prove that mankind is responsible for it, the elephant in the room point conveniently ignored by the alarmist groups. They must be consumed by guilt and would have us all join them wearing hair shirts in a joyless universe.

I still have a nagging attraction to J. Lovelock's gaia theories which basically says that the earth is a self regulating system. If it get's warmer in one area, then it gets colder somewhere else to manitain the balance. As an example, many harp on about the arctic ice, but why has the antarctic ice been increasing for many years ?. Also, why has there been almost nil increase in average global temperatures over the last decade or more ?. Even the IPCC seem to have stubbed a toe on that one, if you read between the lines of their latest report.

Of course, I may be just as mad in my opinions as anyone else. As an engineer, not a climate scientist, but what is really needed is joined up scientific method applied to the problem and less hypothesis reeled out as fact...

Re: greenies are wrong about almost everything

I'm an engineer as well and what annoys me about the current debate isn't about who is right about the causes, but the fact that governments have already made up their mind and expect us all to wear a hair shirt, rather than strict calls for hard evidence that we are to blame. From what I can see, the issue is far from decided and even the most recent IPCC report has started to hint at doubts, though you would never know it, reading the media.

I think part of this is the easliy tapped into collective guilt of humanity about mankind's raping of the planet's natural resources (of which there is no doubt) and people are easliy led into thjinking "it's all out fault, we all deserve to die", when the truth may be quite different. You really have to read all the arguments and evidence, deniers and supporters, to get the big picture...

Netgear router admin hole is WIDE OPEN, but DON'T you dare go in, warns infosec bod

Re: SOHO = Garbage

Yes, older cisco stuff like the 515 is cheap on ebay, but the reason is that the asdm gui interface is really hard work and primitive. If you want a reliable and inuitive open source firewall router, try pfSense, a freeBSD effort. Have tried probably all the o/s router projects over the last 10 years or so, but pfsense just gets the job done and has configuration options covering just about every need. You can also install the snort package and all the tables, which gives you dpi that works for free. Coincidentally, cisco have just bought out the rights to snort, or similar, so perhaps not such a bad choice. Compared with the Cisco's Asdm, setup is a breeze and you can have something functional in less than an hour. You probably won't need to read the manual at all, other than for the more arcane details.

The only problem with building your own router is that older low consumption P3 and celeron class machines are all getting a bit long in the tooth now. The only way to get reliable and cheap hardware is via P4 or later class machines, but they do draw a lot of power. Solution here was to replace the (socket 478) 3GHz cpu with the 1.6GHZ version, which reduced the power consumption from 90-100w to 40w, with power saving enabled.

There's good stuff out there, if you are prepared to do a bit of work yourself and learn a lot as well...

Don't crack that Mac: Almost NOTHING in new Retina MacBook Pros can be replaced

That's because Apple are cheap consumer electronics quality with added hype, while Dell build primarily for the corporate market, where a down machine costs money. Same with the old Compaq machines - one torx driver to replace any part. Sure, they all use the same componts these days, but it's how they are screwed together. Having said that, gluing everything together in the case provides added stiffness and allows thinner plastic all round, so a win win situation all round, I guess ?.

I see no advantage to buy Apple, when a good quality laptop would have the same or better performance, easy replacement of parts and most likely more affordable apps. I guess you all must have seen this:

Euro Parliament votes to end data sharing with US – the NSA swiped the bytes anyway

Re: The unsocial terrorist network ..

Right. They may catch a few amateurs that way, but the ones they really need to stop, the most dangerous, are most likely just as intelligent as they are and would never use any kind of traceable public comms system. If you are doing something dodgy, you would have to assume that everything is suspect. Wasn't it Osama BL that used personal trusted couriers for communication ?.

All this snooping on the soft target of computeres and electronc communications suggests more than a whif of self agrandisement, justification for big budgets, illusions of grandeur and posturing and for what end ?. Reminds me of the old Spy vs Spy strip in Mad magazine. Seemed funny at the time. (Heck, did I ever read that :-). Yeah, i'm sure there are real threats, but submitting to all this just to stop the occasional bomb in a crowded shopping centre seems like a bad deal to me. There will always be those that get through the net and we have to accept that.

In the end, it's about the sort of society we want to live in: One in which the assumption is that most people are honest and have decent intentions, or the sort where everyone is always a suspect. The latter encourages paranoia, extremism and has a corrosive effect on all human interactions. Even Thatcher didn't turn this country into a police state after the outrage of the Brighton bombing, so why should we have to submit to it now ?...

Why Bletchley Park could never happen today

I was living in London, near Kilburn when the pub got bombed and was near enough to hear the bang. Compared to now, we had probably orders of magnitude more terrorist activity at the peak of the troubles, but we never allowed that to turn this country into a quasi police state, even after the Brighton bombing. Of course, this country always did bend over for anyone who offered enough cash. The NSA being the current client and gchq getting paid a tidy sum to proxy what can't be done legally in the US.

More cctv than the former E Germany and legislation (RIPA) that allows councils to snoop on citizens who are supected of filing bins too full, or "cheating" to get theri kids into a preferred school. Then, blanket surveillance of everybody by unaccountables and you are already nearly at Orwell's nightmare. Sorry, but it's not ok by any measure. As for "parliamentary oversight", it's a joke, probably because they know they are at the edge of the law and really don't want to know what they are up to. All this, just to catch a couple of plots being plotted every year. Not even good value for money.

As for privacy, some will argue that all this is ok because we live in a democracy, but what happens if we get an extreme right or left wing government in power, with all that "useful" infrastructure already in place ?. The last government presided over the most sustained attack on civil liberties and privacy in a hundred years, but will the country never wake up ?...

PC addict RM finally quits its building habit, plans to axe 300 jobs

Re: Sad day

No, i've not seen any of their products for ages either, but let's not get too misty eyed. Their products were underwhelming and overpriced. I used to buy cmos ic's from their Cowley Rd shop long before they started building computers. I thought their early Z80 boxes were quite good for those wanting to learn about hardware and asm programming, even if they were expensive and stuff like the ribbon cable bus system was a bit of a cheap hack. Suddenly though, it seemed like they were supplying all the schools in the county, when there were loads of other uk vendors building competent and cost effective machines. How did this happen ?. Dunno, but just felt they were in no way working for the common good at any time, despite all the pleasantries...

Again, ymmv of course...

Chris

Not exactly, I was the governor responsible for IT when the local primary school was being rebuilt. I got two quotes for the new server and infrastructure, from RM and one other. The other was cheaper by several thousand pounds, for what was essentially the same hardware config, but RM got the business because they had a monopoly on the software (sub licensed from a US company, iirc) and they got the business. There were various issues which I felt showed at least lack of due diligence, or worst. For example, an upgrade quote that included a fibre optic network card (500.00 ukp), when the whole network was copper and in fact, there was already such a card in the server lying unused. All efforts to query this were swept under the carpet by a bedazzled headmaster, at a time when we had to get rid of a teacher due to budget pressures. (I was on the budget committee as well) In at least one school that my OH worked in, there was an RM "advisor" governor, which I saw as a clear confict of interest, but apparently not uncommon, at least in the Oxford area. I would add that i've worked in IT and electronic design at various levels for 3 decades, do understand h/w and s/w, don't like flannel, which is what we seemed to get much of the time.

My overall take on it is that they only stayed in the h/w business for so long by charging top $ for everything and other thoughts that are better not voiced in a public forum.

Ymmv, of course....

Re: Permanent 4 wheel drive

We're a a two car family, 4x4 for the rough stuff, school run, shopping etc and tidy car for business. Land Rovers and Isuzu for the 4x4 and variety of 60's to 80's classic Alfas for many years. Looking round for a good value, strong car for a contract in Ipswich in 1993, 2k budget. Could have been an old Saab or Audi, but finally bought a 90 quattro with 130k miles on the clock. It was a revelation. At last, a car that never broke down, needed no oil between changes (The last Alfa, 1984 GTV6 = ~300 miles per pint when I sold it), actually steered around corners like it was on rails and not a squeak or rattle anywhere. Rarely needed parts / nor had to open the bonnet either.

Not much has changed - bought a 4 year old S2 coupe in 1998 which I still have. Nearly 20 years old and still capable. I mean, who needs a tail happy car ?. Just wastes power in the process of going round corners :-). What do I replace it with ?. The quattros will slide, especially in the wet, but only when really provoked, never in normal use.

Anatomy of a killer bug: How just 5 characters can murder iPhone, Mac apps

Re: -1 = Error ?

I think you are looking at this from the wrong starting point. It's poor practice to mix data and control / status inband within the same variable.. ie: A function that normally returns the result of a computation should not return an invalid value to indicate failure. Better to call that function with a pointer to the output , then use an enumerated status type to return success / fail. One of the fundamental things about programming is being fussy about data typing and for embedded work at least, you nearly always need to know and track the size and type of variables.

What was the title of that old s/w engineering book ?

Nothing wrong with the youth of today. They are just as rebelious and arrogantly (un)sure of themselves as we all were at that age :-).

The problem is that programming is now seen as easy, when it never was or is easy to design and build robust systems. While any fool can write a two page utility that works, designing systems takes knowledge of data structures, algorithmics, hardware capabilities and limitations to get the best results. I wonder how many web programmers that you meet these days have any clue about what goes on under the hood, in the hardware, have ever read a book on data structures, or operating system principles ?...

Chris

Re: Compulsory casts.

Ime, it's typical of modern programming idiom in some areas, where people are sloppy about typing and sloppy about algorithm design, or just plain cut and paste bad code from elsewhere. K&R and other programming texts actually encourage this by using signed types (char, int etc) as the default, but signed types should only be used where actually needed, ie, for arithmetic ops, with the default unsigned everywhere else. It's the same story with the original C standard library, which tended to use (signed) int or char for everything. There, the function typing is a real mess, but may have a historical context excuse..

Back in the days of assembler, it was quite common to find bugs eg: compare or increment / decrement op, followed by a signed branch when processing unsigned values. The bug was perhaps discovered much later when the value flipped the overflow or sign bit. If you do a lot of embedded work, failure to use of the correct type is something you ignore at your peril and standards like Misra specifically warn against this sort of thing.

Programming != Software engineering :-)...

Until we are absolutely sure who carried out the attack, what can we do ? and even then, why isn't the Arab League dealing with this ?. It's not our conflict and whatever we do, it's going to have bad consequences.

The first question to ask when trying to analyse any confilct in the middle east is: what is the state of israel's interest in this ?. The second is: Who has the most to lose and who the most to gain ?. Can't answer the first in a sentence, but for the second, it's obvious that the regime has the most to lose, while the rebels have the most to gain by pulling the west into the conflict. I agree that it's quite possible that the regime are responsible. but many military personnel have defected and some most likely with chem weapons experience, so how do we prove who is responsible.

Happy birthday MIDI 1.0: Getting pop stars wired for 30 years

Re: One really cool feature...

Current loop ?.

I worked in sound engineering / mixer design in London in the 1970's (shows my age, etc :-) and then went on to work on an electronic piano micro controller design for HH Electronic in 1979. It was an 8 note polyphonic design that used a 6502 cpu and various cmos logic to provide a touch sensitive keyboard. It also had a serial current loop interface running at 31.25Khz, that allowed coupling between two or more pianos, sequencer or other instruments, so that playing any instrument in the loop would play the others as well. The interface used a 25 pin D connector, frame oriented protocol with checksum and, iirc, optocouplers at the receiving end. Software development using a Rockwell AIM65, with the sort of single line assembler where you have to go back later to fill in all the branch targets.

Mike Harrison, the MD of HH, had plans for a whole range of instruments, but the company went into receivership later. Anyway, uk design and many, many years before midi hit the market and very similar in concept...

Re: I think I've spotted..

From the reviews i've read, not a bad product at all. As for the secure boot (EFI ?) and Arm processor, nothng that other vendors aren't doing. Arm was chosen most likely because it is becoming more widespead in trad x86 areas, is very good on power and anyway, Intel don't have anything with that kind of power envelope at all. Arm is also the most widely used cpu range in history, in just about every mobile phone, including all the Apple products, all the slabs that run Android, good development tools etc, so what's the problerm ?. Compared with the Ipad, which is completely locked down and doesn't seem to connect to anything interesting, unless approved by Apple, the uSoft product could be a valid alternative and will have more connectivity right out of the box, secure boot or not.
