Fancy a mile-high EARJOB? We've had five!

AJames

Appreciate the review, but it would have been nice to see a few specs or measurements as well.

Also, several inaccuracies on the first page gave me doubts:

1. Noise canceling headphones are always the active kind. Passive "noise-islolating" headphones may attenuate noise, but they do not in any way "cancel" noise. Please correct your terminology.

2. Noise canceling headphones do not make you "think" that you do not hear the noise, they actually apply energy to cancel the sound wave so that it isn't there any more.

3. You do not have to be out of your mind to wear noise-canceling earbuds during a flight. While most earbuds may be less comfortable for long-term wear, there are some well-designed ones that that can be reasonably comfortable. They can do an excellent job of passive noise isolation in addition to the active noise canceling, and they have the added advantage that on many flights you are allowed to wear earbuds during the takeoff and landing phases of flight (the noisiest) while you are not allowed to wear headphones.

Dead device walking: Apple iPod Touch 6th generation

AJames

Cheapest entry level to iOS

If there's one good reason to keep the iPod Touch around, it's because it's the cheapest entry-level iOS device. If you want to be able to use all those great iOS apps without paying for an iPhone or iPad, this is the way.

Of course there are a few significant drawbacks: the battery lifespan sucks: it will be practically dead in 2 years, and it's non-replaceable. And contrary to the comments made in this article, the sound quality of the iPod Touch also sucks (all recent models). It is distinctly worse than classic iPod models and the few remaining competing music players. I'm no snob about barely-audible differences in audio quality, but the iPod Touch is worse than it should be.

Nothing new for Neil Young

He's been ranting for years about the sound quality of compressed music. The current battle over streaming quality is just his latest opportunity to go public about it again. I'm sure he's sincere, but a lot of people sincerely believe things that are wrong. Could he pass this test?: http://www.npr.org/sections/therecord/2015/06/02/411473508/how-well-can-you-hear-audio-quality

Bloke called Rod struck by lightning for second time

AJames

Presumably the odds of being struck twice in a lifetime are 1 in 3000 squared, or 1 in 9 million. That would mean that it will probably happen to around 30 Americans.

Super Cali goes ballistic – Uber says it's bogus (even though its contract is something quite atrocious)

AJames

No surprise

When I was working as a morning newspaper delivery boy 30 years ago, a group challenged the newspaper over their poor treatment of the delivery boys under employment law. The newspaper claimed that they were independent contractors, but the judge ruled that the newspaper could not call them independent and still control the end price of the newspaper to customers and the delivery terms and conditions. Welcome to the law, Uber.

Hated smart meters likely to be 'a costly failure' – MPs

AJames

Missing a major source of savings

Here in British Columbia, Canada the local electrical utility BC Hydro told the public that they would offset part the cost of their $1 billion smart meter program by catching and shutting down more marijuana grow operations that were stealing power. They failed to explain how smart meters would help catch these illegal operators known for bypassing their electrical meters to steal power directly from the grid. Sadly their plan doesn't seem to have worked, and instead we are facing huge increases in electrical rates to pay for the smart meters.

ALIENS are surely AMONG US: Average star has TWO potentially Earth-like worlds

AJames

What aliens would say to us if they could

Among the many theories proposed as to why aliens aren't communicating with us, one of the most disturbing is that if they could, what they would say to us is:

"Shut up, you fools!"

We're like a lost fawn bleating in the forest for its mother. We're likely to attract the attention of whatever it is that has everyone else staying quiet and hiding. That's why there has been some criticism of certain experiments attempting to broadcast from earth to other potentially-inhabited star systems. Is it worth taking the chance? Do you want someone else taking that chance on behalf of all of us?

Go Canada: Now ILLEGAL to auto-update software without 'consent'

AJames

Re: Not bad

The problem is that it's worse than just futile. The last time they tried this sort of thing (i.e., their anti-spam legislation that required companies to obtain explicit consent to communicate with customers), all Canadian companies had to waste a vast amount of effort and money sending out emails seeking permission to continue communicating with their customers. People were overwhelmed with the volume of messages (hmmm, sounds a lot like the problem they were trying to solve in the first place), and probably missed responding to some that they should have. Of course real spam volumes were unaffected because almost all of it comes from spammers outside the country who don't care about Canadian legislation. It was pointless political posturing that ended up being worse than the problem it purported to solve, as usual. I suspect this latest legislation will be the same.

Mr President, is this a war on hackers – or a war on people stopping hackers?

AJames

With friends like these...

I have to say that Mr. Obama has been a huge disappointment to his small-d democratic constituency in the United States and internationally. Not only has he failed to deliver on almost every front that he promised, he has frankly shown a worrying expediency in accommodating lobbyists and a lack of commitment to the ideals he espouses in his speeches. Let this been a lesson for big-D Democrats next time they vote: ignore the speechifying and take a closer look at the man and his track record.

It's nice to see someone try to restrain the rush to implement a global police state. Certainly the Harper government here in Canada used the sad incident of violence by a single mentally-disturbed individual as an excuse to press its agenda of increased secret surveillance.

Yahoo! dumps! thing! that! made! it! Yahoo! and! told! to! bed! AOL!

Yahoo does have value

I've used Yahoo's email, calendar, contacts, and groups for many years, both at home and at work, and I've always been pretty happy to have all that functionality for free. Yes, Google and Microsoft have improved their offerings in recent years, and like everyone else I'm forced to use Google for some things, but I stick with Yahoo as my go-to choice. If they started charging a fee for business services, I would pay it. I just wish they would quit fiddling with the interface design. They keep breaking things while they are re-arranging them to no apparent purpose.

SanDisk Extreme Pro SSD – courting speed freaks and gamers

AJames

But can you rely on SanDisk's support

I have a SanDisk SSD on the system I'm using, which I bought because of the great performance specs. Only to find a few months later that performance was deteriorating rapidly because of a firmware bug in the Sandforce controller. It turned out that every SSD manufacturer was aware of this bug and had agreed not to mention while awaiting a fix from Sandforce. When the bug was reported publicly, every SSD manufacturer other than SanDisk acknowledged the problem, apologized to customers, and released the fix as promptly as possible. SanDisk stonewalled customers, refusing to respond. Eventually they caved in and release a bug fix for their product, months after all the other manufacturers. I suspect that they would have quietly let it slide if the issue hadn't become public. Draw your own conclusions, but I'm avoiding SanDisk products in future.

I have both iOS and Android devices, and it's pretty clear that iOS is still the champ when it comes to usability and reliability. My latest phone uses Android 4.4.4, and I often have the urge to bash it against the wall until there's nothing left buy tiny bits! Not the phone's fault, it's all Android and Google to blame.

What could possibly go wrong? Banks could provide ID assurance for Gov.UK – report

AJames

Re: Meh

Canada too. When I want to access many types of government business or personal service sites, I have a choice of signing in with my banking ID from certain approved private bank partners, or applying for a separate government web ID that takes several steps and several months to obtain (and no, it's not universal, various other government services require dozens of other unique IDs). I use the bank partner ID, but I'm not happy about it. The government leaks private information like a sieve if the history of the last few years is any indication.

Banking apps: Handy, can grab all your money... and RIDDLED with coding flaws

AJames

Not surprising

I don't think anyone is surprised by this. You could choose any random group of software applications and find the same thing. We could hope that mobile banking apps would be better tested than most, but I think we all suspect that they aren't.

From my own perspective of decades of experience as a software developer, product manager, and software business owner, I know it's really about the money, but I'd also like to point the finger of blame at two technical issues:

1. The C language and its derivatives. Biggest mistake in the history of computers. Every time you hear about a buffer overflow error in software, realize that it's due to a fundamental design flaw in the C language that leads to the same error repeated over and over. If civil engineers had used building techniques as flawed as the C language, our civilization would lie in ruins today.

2. The preferred modern software development method of "code and test incrementally until it doesn't crash any more". Naturally produces poorly tested software riddled with bugs. Reminds me of the early history of constructing railroad bridges: no need for detailed analysis, if it falls down we'll double the strength and try again.

Americans to be guinea pigs in vast chip-and-PIN security experiment

AJames

Americans are so funny

Yes, by all means let's have a vast chip-and-PIN experiment. Except that the rest of the world has been on chip-and-PIN for years. Next you'll be telling us about a radical experiment with a brand-new system of decimal measurements!

In any case, it's not so much about security as it is about liability. Concurrent with the switch to a chip-and-PIN card, you will get a nice little change of service agreement from your bank with lots of fine print which basically says that you are deemed 100% liable for any card transactions which they claim have used your PIN.

No more of those messy fraud investigations, the customer is responsible! Never mind those pesky cases where the customer claims that he was half a world away and has never shared his PIN with anyone. Never mind those cases where the it turns out that the bank lied when they claimed that the PIN was used. Minor incidents, nothing to get in the way of a great innovation in liabilityxxxxx I mean of course security.

Presto! After Supreme Court loss, Aereo says it's a cable company now

AJames

Disingenuous

The broadcast network lawyers are astonished that Aereo would offer a defence that appears to contradict their initial contention that they aren't a cable company? What law school did they attend where they didn't learn about "argument in the alternative"? Even I've seen that routine legal strategy in small claims court, as in "it wasn't me driving that car that hit you, but if it was, then it wasn't my fault".

Google kills its successful social network. Yes, we mean Orkut

AJames

Re: Well, that's annoying

I turned one of my Gmail accounts into a Google+ account, and I see that Google actually is smart enough to tell you which of your Orkut friends already have Google+ accounts, and it lets you link up automatically.

I had a moment's pause though when the Google+ setup asked me to agree that "I understand the changes that this will make to my Picasa Web Albums". Those changes turn out to be that your web photo albums that you shared with specific friends will now be shared with everyone on Google+ unless you restrict them.

Well, that's annoying

I have many friends in Brazil who I have stayed in touch with over the years using Orkut. Now I'll have to track them all down individually and get linked up to them on another service before September. I can see why Google can't simply transfer these links automatically - few people are going to have a Google+ account, and Google wouldn't have permission to set up Facebook links. But if they were smarter they could have provided some sort of automatic global notification, e.g., send out a message to all contacts saying "Your friend X is now on Google+, click here if you want to link up on Google+ [Create account]".

Redmond reinstates infosec mailing list after Canadian law panic

AJames

Another dumb idea

Another dumb idea brought to you by politicians who want to appear to be doing something.

Predictably it hasn't had any effect on spam, since almost all of the sources are outside of Canada have never heard of this legislation, and wouldn't care if they did. As noted in the article, most small businesses in Canada were unaware of it until recently, and have no idea how it would affect them.

The reason why everyone is aware of it now is that our mailboxes have been flooded with requests from legitimate businesses to confirm that we still want to receive important emails from them. In view of the confusing wording of the law, they all felt it was best to confirm compliance. As a result businesses across the country are spending millions of dollars going through a compliance process or just responding to all these requests. Another own goal by our politicians!

New MH370 search zone picked using just seven satellite 'handshakes'

AJames

Satellite data is all they have to go on

There was some doubt about the satellite data early on because Inmarsat wasn't releasing any details, and the aircraft flight path that it indicated was so unlikely that it was hard to believe without any corroborating information or any good theory of how it could have happened.

There is still no corroborating information, and still no good theory about what happened, but enough experts have gone over the satellite data in detail now to confirm that the flight path is almost certain to be approximately correct. It's not impossible to find other flight paths that could produce the same readings, but they are very unlikely. The problem is that there are enough unresolvable uncertainties in the calculation that the area of ocean to be covered is still huge.

We'll probably never know what happened until the wreckage is found - and even then it might still be difficult. Shattered debris from a high-speed crash into the ocean, scoured by currents for months or years, black boxes that would have recycled every 2 hours during the flight even if they can be found - they might not tell enough of the story. Unfortunately the best chance to figure out what went wrong would be if there's a similar initial incident on another 777.

SpaceX billionaire claims Air Force official 'likely' made job-for-spy-sat-contract deal

Understanding how the game is played

To understand this you need to know how the defence procurement game is played. Filing a protest and making Twitter comments is not done lightly, it's part of a carefully evaluated corporate strategy. Almost all major procurement contracts are ultimately decided by uncompetitive backroom deals that are years in the making, and a whole lot of people get paid off with favours to make it happen. It's understood that everybody eventually gets their turn at the next contract if not this one, as long as they avoid messy public protests. But once in a while things go a little too far, and it's time to make a big, messy protest. There is zero chance that the protest will be successful, and it's understood that the protesting company will be punished for it. But it's intended to give notice that the government side needs to rein things in and play fair in the future, or else their normally-tame bidder will blow them all up. For established companies it has to be done about once every 10 years, or they'll think the company is a pushover that can safely be ignored when they're doling out the procurements. For a new player like Space-X, they have to be more aggressive to muscle their way to the table.

Inmarsat: Doppler effect helped 'locate' MH370

AJames

Re: Truly astonishing amount of information stored

It looks like those first 3 data points after 2am local time are from a single ping message where the velocity changed rapidly throughout the ping, giving them 3 separate readings. They think it's because the aircraft was turning. How long does a ping take?

If that's the case, the Malaysians are correct in saying that there were 6 pings, and everyone has been wrong in assuming the pings were hourly. The interval appears to be slightly longer on average and slightly random.

0

AJames

I don't see how that would work. Knowing the satellite wobble can only tell you about the motion of the satellite, not the motion of the aircraft.

Perhaps it's more to do with the fact that if the aircraft flies to the south it crosses over the equator, so initially it is pointing slightly more toward the satellite as it approaches the equator and then slightly more away after it crosses the equator. Whereas on the northern route it starts out north of the equator and continues north.

But looking at the geometry here, two things stand out:

There are several key assumptions required about what the aircraft actually did in order to correlate this analysis with a real world path. One can imagine other alternative aircraft paths that could fit the data equally well if it didn't actually fly north or south.

There are few data points, and the random motion of the aircraft in the air has got to be almost on par with the small velocity differences that InMarSat is trying to read. Where are the error bars on this chart? Where is the statistical analysis of likely this fit is?

Re: Truly astonishing amount of information stored

Finally, some real information in the link from the article! Too bad it's still a pretty long chain from InMarSat through 2 other agencies to a Facebook page. I assume the Annex referred to is just the 3 diagrams?

But the chart raises several questions:

Why does the Malaysian release say that 6 pings were received after the aircraft disappeared, while the chart shows 7 (not counting the final partial ping)?

Why does the chart show measured data points that are clearly not hourly when all sources until now have said that the pings were on a regular hourly schedule at 11 minutes after the hour?

Reg tries out Google's Chromecast: Yep, we even tested smut sites

AJames

Tab-casting versus handover

When you tab-cast anything from your Chrome browser, your PC is indeed doing the heavy lifting. It has to transcode the incoming video stream to a compatible format and re-transmit it to the Chromecast. The Google Cast extension in Chrome that does this is not very efficient, and the video stutters, quite badly on slower computers. The WiFi connection doesn't really enter into it.

When you cast from the BBC iPlayer app on Android, it instead hands over streaming to the Chromecast itself. You can shut down your Android device entirely if you wish after starting playback on the Chromecast. In this mode you will find that the BBC iPlayer video streams smoothly.

Planes fail to find 'credible' candidate for flight MH370 wreckage

AJames

There are a lot of limitations to satellite surveillance that you wouldn't necessarily be aware of. The satellites follow a polar orbit that only brings them over a given point on the earth's surface every few days typically. There aren't ground stations everywhere to receive a real-time downlink, recorders are limited and unreliable, and orbital relay systems not available in most cases. There's a hard bandwidth limit that means you can have detail or broad coverage, but not both. There's a limited power budget which means the satellite may not be able to transmit all the time. That's especially true for Synthetic Aperture Radar (SAR) satellites, and the Australian images are clearly SAR (probably Radarsat). Considerable post-processing is required for SAR, so you aren't going to get images right away - hence the delay of days on the Australian images.

Re: BUT...

The ACARS on MH370 only transmitted data every 30 minutes. Somebody misunderstood that initially and started the whole "suspiciously disabled before the last radio transmission" theory. Malaysian authorities later realized the mistake and retracted the whole thing, but the damage was done. It lingers in people's minds that there was something suspicious about how the onboard systems were turned off that confirms it was an intentional disappearance.

MH370 airliner MYSTERY: The El Reg Pub/Dinner-party Guide

AJames

Re: The simplest explanation and confirmation bias

To be clear, the article we are writing is about the psychology of the investigation rather than the technical details, so we aren't attempting to decide which is the correct explanation based on the limited and often inaccurate information that has been published so far. However we obviously need to understand the technical evidence in order to understand how it has influenced the investigation.

I discount the military radar data because I am familiar with such radar data and I have a good idea what it does or doesn't show. For those who aren't personally familiar, I suggest you read the accounts of the incident where the U.S.S. Vincennes shot down an Iranian airliner by mistake. Although equipped with a very advanced AEGIS phased array radar system, they identified the Airbus airliner as an F14 fighter and thought it was descending toward the ship when it was actually climbing to cruising altitude. It was only 9 miles away when they decided to fire missiles at it. Does that tell you enough about the ability of military radars to identify unknown targets under ideal conditions of close range and no terrain clutter?

I have no doubt that the InMarSat engineers are very competent and are working diligently to clarify and verify their data. I also note that InMarSat has said nothing much officially since their initial hasty comments to the press. Why would I doubt their abilities? Here's a couple of things to think about:

1. I doubt that InMarSat's satellite ping data is identified as "Malaysian Airlines Flight MH370". It probably has a transmitter number assigned to Malaysian Airlines, and they are relying on Malaysian Airlines to give them the correct number from their records. Of course the aircraft itself is no longer available to verify that they have the right number...

2. Do you remember when NASA's Mars Climate Orbiter crashed into Mars and was lost because an engineer confused metric and imperial units? Engineers make mistakes, even basic dumb mistakes. Maybe like not converting time zones correctly when analyzing data in a way they have never been asked to do before?

I'm not saying that it's definitely a mistake. Just that we don't know until it's verified very carefully, and it's a lot to hang a very expensive investigation on. You would want to be really, really sure.

The simplest explanation and confirmation bias

The simplest explanation is that MH370 crashed into the sea near where it disappeared, and the rest of the shaky evidence and wild speculation is simply wrong (as much of it has already proven to be).

I'm working on an article to that effect with an associate who specializes in the psychology of investigators and the ways that investigations can go wrong (we don't expect the missing flight to be found before the article is published). This case is a classic, with all the signs. My associate doesn't know how to evaluate the technical details in the reporting, so I'm helping out as an engineer who knows a lot about air traffic control systems and satellite systems. While there is certainly some technical evidence of a flight diversion, I have to say that it has been very poorly reported, and I consider it at least as questionable as other evidence that has already proven false.

Most people don't seem to understand the need to evaluate individual bits of evidence independently in the early stages of an investigation to avoid "confirmation bias". One bit of questionable evidence leads to a theory, and suddenly everyone is trying to confirm that theory, adding more questionable evidence that isn't independent while ignoring other evidence that doesn't fit the theory.

There is certainly some evidence that the flight was diverted, and I wouldn't rule out that it might well prove to have been in the end. But extraordinary claims require extraordinary evidence, and so far there are only two bits of evidence that amount to anything in my view:

1. The wreckage hasn't been found in the area of disappearance. In every previous case of an airliner crashing at sea, floating debris and bodies were found within days. There are possible explanations, but I still think it's a key point.

2. The supposed InMarSat data. The problem with this is that the news reports are extremely vague and often inaccurate. It may consist of a single data point, and having never looked for such data before, InMarSat officials probably have no idea how accurate or error-prone it may be. Any number of possible errors could render it meaningless, such as a mis-identification of the transmitter number, incorrect conversion of the time stamp, or incomplete data stuck in a buffer being flushed out hours later.

The military radar data is nonsense.

It's not much on which to base a lengthy and extremely expensive search effort when common sense suggests that the original search area is more likely to be correct. Since it's no longer an emergency, the investigators should sit back, clear their heads, and go over the evidence again with fresh eyes and more in-depth analysis.

A startup could've made a better Obamacare site, says CloudFlare boss

AJames

Who's in charge?

I've been involved in a number of these government-driven projects in my career, and the problem is usually a few wannabee system designers on the government side who produce unrealistic specifications and want the contractors to comply with them. The contractors are happy to do so if their price is met, even when they know that the government spec is unrealistic. Example: the UK side of the North Atlantic air traffic control system that fell over on its first day of operation because there were too many aircraft. The contractor pointed to the capacity spec they were given and the fact that it was exceeded, making them technically blameless. How could a huge development and implementation team not know how many aircraft to expect? They did of course, but the government side set the spec many years earlier, failing to allow for growth, and the contractor saw their job as delivering to that spec.

Your kids' chances of becoming programmers? ZERO

AJames

Different style today

I learned to program in the olden days too (I hate to tell you how old!), and I like to delude myself that I can still bash out a decent program in any modern language faster than the development team of "kids" I have working for me these days. :)

The biggest change I've seen over the years is that developers today are totally dependent on interactive debugging to hack out a program by trial and error. They code and test incrementally until it does what it has to and doesn't crash any more, then they call it done and submit it for product integration. Of course their code then proceeds to fall over every time it's presented with a new variation in user input or sequence of events that they didn't test. I see this effect everywhere in the software that we all use every day, which I'm sure is being developed by the same method.

Four ways the Guardian could have protected Snowden – by THE NSA

What the spooks are actually after

I think we're missing the point on what information the spooks are actually after. The favourite tool of police and military intelligence agencies around the world is i2 Analyst Notebook (look it up). It's designed to track associations between people, events, and other things, and to show them in a nice graphical presentation. To some extent the tool drives the intelligence gathering. What it wants is the associations: the contact lists, the meta-data of who contacted who, who was at a common place/event etc.. They don't care so much about the why - they can make up that part for themselves.

What idiotic comments by Beer. Few countries have the plentiful IT skills that Brazil has, and does he not realize that the country extends into the temperate south where it snows in the winter?

Re: Doesn't Matter

I agree completely with that policy by Brazil. It's the only was to establish international respect. When Canada began requiring pre-arranged visas for visitors from Brazil, Brazil was quick to require the same for visiting Canadians. When Canada raised the price of a visa, so did Brazil. I am able to avoid the cost by using my British passport to enter Brazil, but that means I'm embarrassed whenever I arrive there shortly after some new outrage perpetrated by the British government against Brazil, such as killing an innocent Brazilian on the tube platform because he was wearing a backpack and jacket, or illegally detaining a Brazilian journalist.

Early hardware issues

Good article, and it's time some more thought was put into future video standards.

Historically there were some hardware issues behind those early decisions on interlacing and the power-line-frequency frame rate in addition to the ones mentioned. The key point about interlacing is that it reduces the bandwidth required by half, which was a significant factor in designing the early TV electronics and creating the broadcast channels. It was still a factor in the more recent switch to digital channels.

As for the decision to use the powerline frequency, it's true that one reason was to prevent visible strobing, but the other was that it was just easy and cheap to use the powerline frequency as a reference because it's so reliable and tightly controlled. Accurate crystal oscillators weren't always so cheap as they are today.

Windows NT grandaddy OpenVMS taken out back, single gunshot heard

Thanks for the history

There were a few bits in there that I didn't know.

I still think RSX11M was the best of the many operating systems I've developed software for in my life. The latest versions of Windows and Linux could learn a few lessons.

I used VAX/VMS as well, but the added layers of complexity made it less elegant an fun than RSX. Still, it was a viable alternative technology in the operating system world that's in danger of turning into a monoculture. I still remember the day that the DEC sales team came in to pitch their new corporate-mandated Unix message. Having spent years telling everyone that VMS left Unix in the dust, they seemed lost and confused. DEC never recovered from that.
