Re: short term benefit
I tried one of those too, but it was like watching a rsa key fob tick.
And yes, it had no clue about power factor, so it thought laptop power brick eats double what it really does, and idling wallwarts were overestimated by a factor 10 or so..
Re: Its about time 2G was dropped from coverage maps / statistics.
What good are fines, if operators aren't allowed to build coverage anyway?
How about maps of "We've set aside money to improve coverage here, but unfortunately we haven't received permission to do so"/"blocked by nimbys"
Re: Poor Oisin
JC in anger management therapy? Now that's a tv show I'd watch, especially if it includes segments such as "staying calm driving behind pensioners in caravans".
I don't think any other country equated smart meters with remote control, everyone else is doing "advanced meter".
One directive I don't see mentioned on thereg though, is the one requiring damages and refunds for power outages. It has caused a building boom in Sweden and Finland atleast, with grid operators hurrying to bury electric cables underground so they don't need to pay out so much compensation for outages during storms.
Re: Capacitors - caveat observer!
Also, grounding yourself seems like the last thing you'd want to do.
Intel's graphics is the most popular graphics choice for PCs, makes sense to integrate it in their mainstream offer.
AMD moving to 16nm wont make you happy, by that time Intel will be measuring node size in atoms rather than nm. Both companies make CPUs that are "good enough", anyway.
Re: Mobile and Communications segment saw its revenues plummet by 85.3 per cent.
I have a atom android tablet, and I must say the performance isn't as bad as I thought Atom would be. With performance I also mean batterylife. My Haswell-Y, however, is a bit disappointing.
Intel's kit previously had a price disadvantage, but now that that's fixed (temporarily?), intel is.looking useful.
Iris Pro is the top end Intel graphics. It comes with 128M L4 cache, absent from other intel cpus.
Currently not available as a socketed processor. This is the news, socketed iris pro.
Disappointingly only at 65W TDP, I bet lots of people, regardless if they use the graphics or not, would have loved to have a "full" i7 with L4 cache. Oh well.
On my asus transformer from about the same time era, chrome (and to a lesser extent firefox) spends much of its time writing to the slow emmc. I believe the N7 was also plagued by an extremely slow emmc with around 1-4 WIOPS performance?
This issue is something that has persisted with browsers for a longer time, across platforms. firefox was notoriously slow on Linux, due to the way it wrote cache and browsing history with sqlite. This issue is amplified further on flash based storage, where each tiny write triggers a 8 megabyte read-modify-write cycle. sqlite, being a database ish thing, is paranoid about dataloss, and makes sure the data is on physical storage after each step, with the end result that appending a new url to browser history, to a storage medium where every write request regardless whether it's 50 bytes or 8 megabytes takes on the order of 1 second to complete, you're looking at several seconds just to add to browsing history, let alone disk cache for images etc...
Ever since flash storage started appearing, programmers stopped caring about how they write stuff to disk, because "no moving parts, it's instant so I don't have to care". SSDs only started working like that, through the use of large Arm cores and massively complicated firmwares (that still today occasionally mess up), around the era of Intel M-25 and ocz vertex. Today if you're not careful, you'll get an emmc that still behaves as poorly as the one in N7.
Probably the only company that pays any attention to the issue is Motorola, with the use of f2fs, a filesystem which tries to make life easier for the emmc, boosting performance.

Am I the only one who never swaps sd cards?
I put in a card in my phone, and it stays there until it is obsolete or upgraded to the next faster, bigger, affordable version.. The old one's data copied over and never used again.
Re: MS Might Share Some Blame
I recently discovered the hard way, that restore usb media created in windows refuses to work on empty harddrives, ir if the partition table is corrupt. In other words, if HD is screwed, you're screwed.
However, to my delight, I discovered hidden deep on Microsoft's website a tool which creates Win8 install media battery downloading from ms. You have to pick 32/64 bit, language, and edition correctly, and the resulting usb key will install W8 on a PC with the correct W8 key in bios.
Bye bye per cpumodel benhmarks is already a relity for low power intel CPUs. They're primarily limited by TDP, as in actual power use and not overheating, and the PC maker decides if they want to limit CPU to 4.5W or 11W, or anywhere in between. Add ontop of this efficiency variation from cpu to cpu too.
Also for desktop CPUs, overclockers were buying many haswell i7 from different places, hoping to get one from a "good" batch known to overclock well, and returning if batch lottery didn't play out well. All of the CPUs meet (and exceed) the performance promised by intel, but some exceed it with huge margin.

Re farmers using technology that works.. Couldn't agree more. As part time tech support person, the most complex networks/LANs I've encountered with farmers. Recently one told me "I really regret not signing up the cow for fibre optic internet when I had the chance".
He has fibre to his own house, and a point to point 54Mbps wifi link to the building with the cows some 200m away. There's a "visitor/casual" wifi and lan, and a "infrastructure" LAN, plus home lan+wifi. The infrastructure part of the network is where the milking robot, feed silo management, and god knows what sits. This is, of course, available to him on his smartphone and PC realtime. If a cow gets in an argument with the robot, his phone buzzeds and he can look at the situation and have the robot shoo the cow or bribe it with treats or whatever.
.. But it'd work much better if it wasnt behind a 54Mbps bottleneck.
As for government services? Dump all the paperwork and receipts with specialists that can decode and speak governmentese..
I totally ignore SSL warnings for some sites. Example: I don't care if 4chan connection is secure, wether cat photos leak to third parties or not makes no difference to me. And, if I was posting something more sensitive and less legal than cat photos, SSL is still useless, as it's permanently broken and insecure.
Did their survey take into account these "User's level of safety isn't changed by the use or nonuse of a proper SSL connection"?
As a C guy wrangled into automation, I can onky concur with what people have said before. When I first encountered it, it was a bit like finding a tribe of cavemen in central park.
Siemens came out with a new version if the software I have to use. Haven't tried it yet, but I heard it now takes less than a day to convince it to jnstall on windows other than XP SP1 32bit. The actual install, obce it starts, still takes 6 hours, as the installer consists mostly of a wrapper around a few thousand .bat scripts. Woe if you accept the install directory proposed by the installer, because the installer can't actually install properly if destination directory contains spaces or any other "funny" chars.
The installer itself is distributed in half a dozen .zip files. Not split inti individual components, you have to recreate the proper directory structure and unzip each i ti the correct directory.
Their "cheap" stuff is actually less bad, with
both linux and windiws versions, and $150 piece of hardware with inputs and outputs, ethernet port and built in webserver that apparently does something useful. But, despite being able to run a webserver, you're still limited to the equivalent of 400 lines of code (let's say python level of density).

I thought it was pretty clear to everyone now, that kickstarters are high risk investments, a bit like venture capital, with the exception that if things turn out well, you get minimal return on investment (i.e. just a trinket or gizmo, or tshirt), and if it turns out bad, you lose all your money and get nothing.
(i participated in tge kickstarter, but never downloaded any if the alphas, betas, and didn't download the game. Didn't like where it was gokng, saw no point in downloading it. Not complaining though, it was always a risk frontdev would make a different game)
Re: Not pirates - just because you don't carry along a CD player anymore...
Initially this levy was set up to "compensate" lost revenues when people were using this newfangled gizmo called tape recorder, ti record radio broadcasts for later and feared repeated playback.
This was later extended to casettes, vhs and beta casettes, writable CDs and DVDs, harddrives in PVRs, eexternal harddrives (but not internal hd when bought separately, and nit empty external hd cases), etc.
It's still known as "casette levy" in Finland.

Liithium-Ion polymer batteries are in the form of a soft pouch, often surrounded by a hard case for extra protection, though devices with non-removable batteries use the device casing itself for that.
"Regular" Lithium-Ion batteries are cylindrical metal cans, where instead of the polymer keeping the components pushed against eachother, the metal container exerts mechanical pressure on its contents.
Cylindrical cells are the most common type used for laptops, with the 18650 size being the most common. (18mm by 65mm). Yiur typical laptop battery has somewhere between 2-9 of these cells, in various parallell and series arrangements. A battery management, protection, and sometimes, "tell laptop this is genuine expensive battery"-chip complete the battery pack, which is then encased in hard plastic.
When a laptop battery fails, it's usually because one set cells in series arrangement has died. The entire pack is limited by its weakest participant. I recently disassembled a dead 6 cell battery. It was arranged as 2P3S, that is, 2 cells in parallell, 3 of these pairs in series. 1 pair was totally dead, had leaked, and its mechanical protection had severed its internal connections. Must've been running hot! Anither pair had so-so performance, and one pair had excellent performance.
Now, laptop battery recycling already takes place in China. Enterpresing people obtain dead laptop batteries, crack them open to harvest the cells that still function a little bit, and reuse them to make "new" laptop batteries. Thesd are sold on ebay, at significantly lower price compared to official genuine packs. The plastic casing, labels and holograms cost cents to make, and are not reused.
The cells nit reused for laptop packs, are given a new shrinkwrap, a fantasy capacity label, sometimes a circuit board is added, and then sold on. There's a significant market with e-cig users and fancy flashlight users, for cylindrical li-ion cells. It's remarkable that such a market exists, considering that no reputable manufacturer willingly or knowingly sell "bare" li-ion cells, thry always require the cells to be either built into a device, or buolt into a battery pack, and measures in place to prevent charging by anything except the designated charger. As such, one can consider all "lose" cells for sale a bit dubious.
Unless your laptop has a 386 or 486 in it, it's almost certainly Li-Ion. The only recent exception to this is OLPC, which had several different options.

Re: Sorry, I can't get excited about NASA's 'new' 1960's Mercury/Gemini/Apollo Space Program v2.0
In terms of actual rocket science, they're keeping the actual good bits of the space shuttle, the SRBs and the space shuttle main engines.
As they don't need to fly any single-orbit missions anymore, they don't need huge wings anymore. The buge wjngs of the shuttle were needed so that on a single orbit polar mission, the shuttle could use its wings to compensate for the earth rotating underneath it, so it could return in a single orbit to its launch site. The air force wanted that, but no missions were actually flown.
Without wings, they can place the orbiter ontop of the rocket, and not have piece of foam and ice smash into it on take off.
The first SRBs to fly will actually be reused from the shuttle, and have flown before. They don't plan to reuse them anymore. If it doesn't pay off, don't do it.
The space shuttle main engines are phenomenal still today, their fuel efficiency is 1.7 times better than that of Saturn V.
Of course, politicians will probably cancel the SLS, which is the most useful bit of all the associated projects...
Have a 1920x1080 IPS windows machine wirh detacheable screen myself. I find myself using it more than my android tablet these days, after google killed 1080p youtube on android.
(I live outside UK)
I remember when men from "the mobile phone company" came survey the local geography. As this is quite a small town, word of the strangers quickly got around, and soon there was quite a crowd, some with their moose hunting rifles "just in case".
When the strangers explained that they were looking for a good site to erect a mobile phone mast, everyone was quick to put their knives and rifles away, shake the hands if the strangers, "I have a hill not far from here you shoukd come look at" - "My hill is the tallest hill in town, it would obviously be mich better", and so on.
Eventually they placed it on my neighbour's hill, not because neighbour had a taller hill, or wanted less money, but because it had easier access.
Anyway, what never quire became clear, was which company was building the mast. There were 3 operators, and stories about whose mast it was varied monthly. Eventually, years later, I found that it was none of them. A small regional ISP had branched out into mast building. They had a line of fibre going i a straight line through the region, and towers placed at intervals along the fibre. To both sides of the fibre gateway, they placed towers that they linked with microwave links. Space in the masts and capacity on their backbone was rented out to any operator.
Re r&d costs, are they saying it takes more effort to make winpho work on different SoCs and with different hardware?
I could sort of believe that, Qualcomm and others happily write android drivers for you. Not so sure about windows drivers..
Well, Nasa pioneered skip aerobraking. Kerbals and ESA use skip lithobraking :)
I'm not a biologist, but the article's mentikn if decoded genome seems weird. In a compsci analogy, i thought the HGP was about reading out the 1s and 0s, into one long string, in the correct order. Except DNA is ternary. I was also under the impression that we know sequences create different yproteins. So perhaps we could say it's it's the equivalent of ibstructions to write values into registers on a computer. What we don't know, is how execution flow is controlled.
So basically we have the program code in executabke form, and we know opcodes that do things like 'write value to register x', but we don't know what each register does, and execution flow, conditionals, etc, are all part of the black box manipulated through registers?
So one big reverse engineering problem, made worse by the original author having poor coding style, nk sense of structure, and winner of obfuscated c contest. Oh, and we dont know how the cpu and its peripherals work either.
This board seems much the same as every other ARM based board that isnt Raspberry Pi: Much better hw for less or same price, but awful software support.
On paper, with somewhere around 8 times the compute performance, twice the ram, and vastly superior bulk IO, one would be could crazy to buy raspberry pi. However, not having to build your own operating system makes rpi win.
Raspberry Pi is in a strange position with regard to future direction. They're more or less stuck with the particular and peculiar Broadcom GPU. Powerhungry GPU designed for set top boxes, with a tiny CPU as coprocessor for displaying the tv guide.. By now there's so much effort put into modifying software to work with the nonstandard drivers and APIs, that switching to another SoC will be starting from scratch. Rpi foundation possibly only entity capable of it, if they can get their users enthusiastic about it.

Buying a drilling rig to just make one hole is very silly.
As someone living in the Nordics, where groubd source heatpumpd are now withib top-3 modt popular heat source for new or newly renovated houses, i csn tell you the hole doesnt cost that much.
Roughly speaking, changing to gshp is a 15kE investment, of which roughly 5k goes to the dude that comes over and parks drilling rig in your yard and naps for 2days as the machine works away.
Oil heating running costs on the order of 3-5kE annually, electric even more.
Wood fired central heating needs something on the order of 3-5ha of forest for comfort, and 2-4 weeks of work put into it, to harvest and process the "free" fuel.
Rules of thumb for renovations or new houses: 100cm of rock wool above and below, same or atleast 60cm on walls. Forced air ventilation with heat exchanger (or even a heat pump), and underfloor heating. Underfloor heating allows system temperature to be kept at around 40C instead of 60-80C as with radiators. Lower system temperature boosts overall efficiency considerably.
For me, Verified by Visa asks me for user/pass (static), and a one time password (always different, pick up new list of 200 at bank when I run out), my bank's favoured authentication scheme. Occasionally I also need to enter a code sent via sms. That feature was opt-in though.
For my friend who's with another bank, it asks for the digits displayed on some small plastic keyfob thing with the letters "RSA" on it. The digits seem to change every few minutes.
Usability is different things to different people.
For the nongeek non nerd, you want a flat menu structurd, because hierarchies are confusing and scary, and the nongeek gives up, because the choices on screen are all interpreted as verbs/commands. i.e. "Why press file, i dont want to file, i want to print".
Additionally, on touchscreens, the touchscreen illiterate needs to be given buttons atleast the size of a thumbprint, because that's how they try to interface with it. Say 3x3 cm buttons. This also helps with the computer illiterate's typical eyeglass scantup, which gives them a reading distance that is further away than their arms can reach. The lack of tactile feedback makes the read first, then push button blind strategy unreliable at best. As there's typically no clear feedback whether a command has been accepted either, the user will try pressing harder and harder, or move to alternative approaches such as punching and stabbing, sometimes with implements..
Everyone who claims something is easy to use should be forced to spend a week with these users. :)

I cant wait until the day Steam games are all kn the cloud. I wouldnt have to worry about constantly upgrading the gaming rig, wouldnt have noise and heat problems in the gaming room, the gaming room could be repurposed.. And, best of all, I wouldnt need to get out of bed to play a game if it ran on, or was streamed to a phpbe, phablet or tablet device..
Around half the people I know of that have bought Win8 machines can't figure out the current authentication system, and thise that do manage to get past the first boot questions are shocked and surprised after the first patch-tuesday enforced boot. "Why do I need a password, this is *my* computer!". Of course they don't remember whatever random keyboard mashing they did a week/month ago to clear "strange questions about my facebook".
Locally in Finland, Stubb has come under criticism for using twitter.
Doesn't matter if it's "aww, look at this cute kitten!", or "difficult negotiations again. please bring coffee", or "just ran marathon, excercise is good for you", mainstream media always interviews political analysts about the "statements by the prime minister" (tweets)
On one hand, "the social media pm" has brought unprecedented transparency into government.. On the other hand, people are quite confused as to why the prime minister declares to the world that the kitten "snuggles" is the cutest kitten ever...
I too find it hard to believe he meant it any other way than <technological progress> makes <old inflexiblecompanies and industries> die. And I don't even vote for his party.
Even with ludicrous fuel tanks, the chances of being able to rendezvous or intercept a target not targeted before launch is unlikely.
Re: Do not write off the low-cost Series 40 featurephone platform
Part of why Nokia failed, was that they did not realize quickly enough that calls are no longer the primary purpose of phones, and that call quality and battery life arent that important either.
1) Bundle win8 with classic shell
2) Call it Windows 9
XP is the only named one that was not a dud, and every second windows is a dud. For that reason, using same methodology as technical stock analysts, a named version in the good slot in the sequence is asking for trouble.
Re: Crap Battery
I bet you nonzero amount of currency that the real reason is novelty wearing off, and you doing less power intensive tasks on it. Or no longer blocking antenna with hand, or your operator boositng coverage.
Re: Battery Life
Roughly first half of the noughties, Nokia did the opposite with the battery meter: full bars until 50%, and then vaguely linear dropoff from there to 1 bar, which was whatever threshold their engineers felt the algorithm could reliably predict there'd be enough power left for orderly shutdown.
This "show full until half" was a neat trick, in a day when users' metric was "check out my new phone, got it 5 days ago, on my first charge, and it still has 5 of 5 battery bars!"

The problem with real world is that conditions are random. The problem with background apps is that they perform random crap, through the random quality network environment, and everyone has different set of crapware installed.
Real world example: At home, on my desk, where even IRDA to celltower would work, standby life without background apps would be on the order of weeks.
Out at sea on an island, with closest tower being a solar/windpowered byuoy, standby time is on the order of hours.
There's already massive power use within the fairly wide "full signal" indicated range, let alone when operating with less than perfect signal indicated...
The only purpose of the batttery life ratings is to compare with other ratings. (and hope they use same methodology across models).
As a sidenote, and as someone who doesnt use apple, I have to say I'm rather envious that iphone brightness goes as low as it goes, and that the volume can go low too. Most devices these day feel like getting stabbed in the eye at lowest brightness, and bleeding eardrums at one step above muted..
Then again, I see other people discussîng max screen brightness and volume, as if they actually want even more , to me, ludicrously high levels... Again, shows that one person's real world can be quite different from another's.
Mostly, li-ion fires can be divided into 2 causes: impurities introduced during manufacturing, and bad battery management systems.
Unfortunately, batteries seem to be poorly understood by most electrical engineers, so the amount of flawed battery management systems out there is rather huge.
Still, the 'rules' are pretty simple: Don't go below 2.80V, don't go above 4.20V. Ever. Not even for a millisecond.
Our clever cost-aware EE will then think "I've got 3 in series, so that means I need to stay between 9V and 12.6V. This is wrong, he needs to monitor all 3 cells individually. There will never be cells matched exactly enough, and stay matched throughout their service life.
So, each cell must be monitored individually. On discharging, the device must shut off when the weakest cell reaches the minimum allowable voltage, or sooner. On charging, the charging current must be reduced when the fullest cell reaches maximum permissible voltage. Preferably you have a circuit that can bleed off some charge from the fullest cells, so that all cells can be charged full.
The EE that reads the datasheet closely enough, will notice that samples if cells are put through overdischarge and overcharge testing, wherd they are taken outside of the permissible voltage range, and demonstratedly don't explode, smoke, or emit excessive heat. He will then make the assumption that the limits are more of a guideline for best cycle life, and the worst that will happen is that the battery dies a bit sooner, and the customer needs to buy a new battery or device sooner.
While it's true thay li-ion cells must withstand such tests without failure, they only need to do it once. That is, one test is performed once, and the specific cell in question is never used again.
The reason for this is that every deviation outside the safe range inflicts accumulating damage to the cell. Accumulating meaning that while a 'small' deviation from the safe range might not cause problems the first time, it could cause issues the 10th time or the 200th time it happens.
At one extreme voltage, the copper inside the cell starts dissolving. If this process reverses, you get conductive copper in random places, potentially causing short circuits, or a string of thin copper might carry current, cause heating, and ignite the cell.
At the other end, the battery evolves metallic lithiun, which is the equivalent of the petrol in your car turning into nitroglycerine. Ungood.
Ghus is kinda similar results to similar research in LiFePo4 cells, where it was found that extremely fast charging can reduce the wear and tear on the cell.
Re: Green Prince of Darkness
High cycle life.
High power density / fast charge
