Apple seem to have had real difficulty manufacturing the 7+, so if you wanted to walk out of the shop with a large Apple phone you got a 6S+; and it seems that most people who want an expensive new phone want a large one.
Complain publicly to @fitbit on Twitter, with photos, and they'll likely send you a new one for free.
I'm on my third.
The USA does this to an extent - if you hold the shares for less than a year, you pay income tax on the profits, whilst if you hold them for longer you pay a lower capital-gains-tax rate.
No, actually Cat8, twisted pair rather than twinax (40GBASE-T). Not sure what black magic they're using in the transceivers. The cable needs to be shielded and tested up to 2GHz, but it is a twisted-pair cable.
25Gbit can be run over a single fibre wavelength or (amazingly) over within-rack lengths of Cat8 copper; 40Gbit either uses four 10Gbit fibres or (more expensive) four wavelengths on a single fibre.
Putting on my pedant hat, ESA had been launching the Galileo satellites on Soyuz rockets owned by Arianespace and launched from their site in French Guyana; so Roscosmos got the money for the launch vehicle to pass through to the manufacturer, but was not responsible for the launch.
(the two earliest Giove satellites did go up from Baikonur)
It's not completely obvious that launching 675kg satellites four at a time on Ariane 5 (which can happily take six tons to the harder-to-reach geosynchronous orbit) is better than launching two at a time on a smaller rocket.
A competing manufacturer of annoying squishy expensive pavements says '5W continuous', so I think that particular problem is just a matter of a badly-written press release.
The problem is that a 5W generator produces £5.70 of electricity a year at retail price, and it seems wildly unlikely that the maintenance of the annoying squishy pavement, let alone the interest on a loan to cover the install price, is of that order of magnitude.
If they're trying to fit a petaflop in five racks for $3 million, the processors will just be sitting there driving the GPUs. My guess is that they're anticipating nVidia, who has quite tight links with POWER, producing a POWER-and-GPU box which might be more cost-effective than the current Xeon-and-GPU box.
($3 million is interesting close to what you get if you divide a petaflop by the current $129k 42.4TF nVidia DGX100 and expect a small discount for buying in bulk)
This is a comment guaranteed to not fill you with delight, but: have you tried the cable in more than one port on your switch? I have some cables that work only in ports 6 and 8 (and, accordingly, a bag of fibre transceivers winging its way to me from fs.com)
And switch vendors seem to think that 'doesn't work with some brands of DAC in some ports' is a problem they address by maintaining a compatibility list, or in the worse cases by mandating you use cables provided by them and made out of mark-up coated in a thick layer of dielectric expense, rather than by fixing their rassenfrassen switch hardware.
Mine's the one with the distress-purchase fibre transceivers in the pocket
Sadly the cheap server motherboards have integrated 10G with SFP+ connectors, and SFP+ to 10GBaseT transceivers don't exist because driving 10GBaseT requires more power than SFP+ is specced to provide.
If you're buying the network card, 10GBaseT is not a bad choice (if you're going to have the exotic cabling faff, at least go for 40Gbit Infiniband and have the extra speed); if it's integrated then you're screwed.
Since Conroe I have expected PCs to last forever. Builds have grown big enough that it's nice on a software-development workstation to have 2GB per thread and ideal to have 4GB per thread, but that's been possible since Haswell.
A problem is that memory controller IP, which is very black magic and comes from a very small number of suppliers, charges a big premium for each extra address line; so it would be a significant extra expense to make a phone or set-top-box SoC which happens to be able to support 16GB, and therefore you're not going to be able to make a nice 16GB devboard around a ubiquitous SoC.
So you have to stop offering really crappy free WiFi. Where's the issue? If your free WiFi is not making your coffee shop a fiver a day in custom, why are you bothering? When almost everyone in the coffee shop will be accessing your wifi using a mobile device which can happily switch to 3G, providing a service worse than 3G is a waste of time.
And Gaia watches them move and measures how far they've moved, so two million of the stars are annotated with velocities already and about a hundred million will be by the end of the mission.
The researchers did do the obvious experiment to see whether any velocities were changing over time, because that would be an exciting result, but didn't find any convincing examples - it turned out simply to be an excellent way to find one category of mistakes matching up stars in the fifteen-year-old Tycho catalogue.
Hipparcos data analysis is a really hairy problem - van Leeuwen spent a decade inventing new data-reduction techniques and re-running the whole analysis, the fact that the satellite was stuck in geostationary transfer orbit because its apogee motor failed to fire didn't help.
Gaia's estimate for the position of the Pleiades is in one of the free-access papers published today, and is unsurprisingly absolutely bang in the middle of the results from Earth-bound telescopes or from astrophysical arguments.
The error in this data release is 0.0002 arc-seconds and the intended error at the end of mission is 0.000007 arc-seconds. Star positions to an accuracy of 7 arc-seconds can be achieved with a DSLR and a reasonable telephoto lens, no need for a two-billion-Euro mission at the L2 Lagrange point.
I think that's a Master, configured to use DFS rather than ADFS at boot
Or think of it as a collection of bits all arriving at the same time and selected so that you didn't have to go and order another PSU and wait two further days for it to turn up, plus a £15 donation to the Raspberry Pi foundation.
It seems you have changed 'BCE' to 'CE' throughout. The Assyrian eclipse was in 763 BCE, we are reasonably confident that the foundation of Rome was 753 BCE, the first year of the Gonghe Regency, after which Chinese chronology is apparently pretty well-known, is 841BCE.
This means the last three paragraphs of the article, which I suspect are commentary inserted by the article author rather than extracted from the source publication, don't make much sense.
The Miyake event was in 775 CE (during the reign of Offa, king of Mercia, and at the end of the reign of Constantine V, Emperor of Byzantium), not 775BCE (around the time of the first Olympic Games in classical Greece, and well before the invention of either Mercia or Byzantium). The other one is 993-994CE (reign of Ethelred the Unready)
Trivial complaint, but '8 x 512GB DDR3L DRAM' clearly ought to read '8 x 512MB DDR3L DRAM' - really very implausible to have more DRAM than Flash in this appliance!
There seems to be some Enterprisey over-engineering going on here; I rather like the idea of a card with a PCIe switch and four or six M.2 NVMe slots on it, so I can run software RAID0 across six cheap Samsung half-terabyte NVMe cards. IDT make a switch chip that would be perfect for this, which costs about $200, so I'd expect a competent Guangzhou shanzhai to make a profit selling the card for £250.
Renishaw is not privately-owned: FTSE listed (ticker RSW), a member of the FTSE250, no sign of an unusually major shareholding by directors. Not a bad company, one of the super-exporters whose stock has soared since Brexit
One's MH370, to which your comment regrettably applies, and the last one is Asiana Airlines 214, which was landed so incompetently at San Francisco that three people died and the plane was destroyed by fire.
I hadn't realised that BA38 (the short-landing at Heathrow caused by ice in the heat-exchanger) had written off the aircraft.
That's exactly what they did; they looked at theyworkforyou.com and then asked the people who designed that to tell them what they needed to do for the Parliament Web site. Seems a pretty decent approach to me.
Ethernet can be over copper or over fibre; it's just a way of wrapping up frames.
"NVMe over Ethernet" I suspect just means that there are 16 bits reserved for queue-number and 16 for position-in-queue in whatever secondary wrapping they're using
That's hardly recent, and it may well be an aspect of culture clash - it's an important plot point, breaking down the relationship between backwoods American boy and outback Australian girl, in _Beyond the Black Stump_ in 1956.
The first transatlantic flight was in a Curtiss seaplane, and stopped at the Azores
We're not building enough houses. The reason for this is the ridiculous post-war imposition of the Green Belt. Abolish planning permission for a couple of decades and we will replace the housing problem with some easier problems to do with public-transport provision and building primary schools.
Why would you bother looking for work in Poland? This is the era of capital; take the money from selling a two-bedroom house in Zone 2, buy an apartment block in Krakow with half of it, stick the other half in UK-based investment funds, and you get to live the rentier dream. Settle down with a nice Polish girl somewhere where you can actually live off the interest.
And that's the case for an awful lot of situations. There are an enormous number of objects for which the total size of the market is smaller than the minimum lot size for the most efficient manufacturing processes.
Being able to move away from using standard parts which aren't quite the right size but are produced efficiently in huge volume by some commoditised supplier, to using parts which are exactly what you need and are produced efficiently-enough in the volume you need is super.
Because there are still an awful lot of poor people in India, and paying people directly to minister to them works better than trying to convince the Indian government to change its fund-allocation priority.
I'm guessing around $2.5 billion, since the article indicates that they reported $0.6G on the $2.6G quarter.
But when it comes to 'price for the smallest thing big enough to do the job', SSD is already winning; the smallest SSD you can get is big enough, and is cheaper than the smallest HDD you can get.
There were a couple of years when I had compute nodes with the OS on 8GB USB2 sticks; I don't recommend this, they do wear out and reinstalling the OS even on a compute node is never as painless as you hope (CUDA drivers :().
I think the author of this story hit the lede: that analysts who presumably know what they're doing have reckoned that there won't be an explosion in data-storage demand from the cloud companies, that they'll keep buying discs at the rate they have been rather than continuing to grow demand at 20% a year.
"Big Data Won't Be That Big" seems a perfectly registerian headline ...
People don't record much video, because taking photos that look sort of about the same category of as good as professional photos isn't terribly hard, but doing that with video is really quite challenging.
The restriction on numbers of photos taken, even with good DSLRs, stopped being SD-card capacity a couple of years back - I'm a pretty enthusiastic photographer, took three 32G SD cards on a three-week trip to South-East Asia and only used half of one. People realize that they don't bother checking through the nineteen shots of a badly-posed monkey that they took by holding the button down, and move to pressing the button once.
If you sell aspirational stuff that lasts, then your customers are delighted that they can sell their iPhone 4S on for a hundred pounds when they buy a 6S+, and the person who gets an iPhone 4S and otherwise would have had some lowest-end Android monstrosity is also delighted. If you're lucky then the second-hand customer will get richer and start buying new.
"It's a far cry from the richer CyanogenMod that burnished the OnePlus One – but OnePlus has had to rebuild from scratch." confuses me: could the article author explain *why* OnePlus had to rebuild from scratch?
And at least one Cupertino-based vendor has; if you want gigabyte per second filesystem access, a Macbook Pro is the way to go.
His vision is highly-trained people. But there is a lot of time in the evenings in which you can read whatever you like, utterly independent of the training you have in how to drill teeth, remove spleens, diagnose common diseases of the kitten, weld two-inch-thick copper plate, cut three pieces of wood so that they fit together into a beautiful corner, write C++, read Danish, design an injection-mould ejector which actually ejects the pieces, locate a sewer pipe two metres underground, convince a CIO that your product meets their needs, or whatever makes you money.
That's the point of reading books. Which you can do happily whatever else you do with your life, and which you will find yourself with a great deal more comfort to do if you have a well-paid career in computing.
Doing a liberal arts degree is expressing a very unusual opinion as to the best way to spend the price of a decent BMW; the difference between reading the books in order to write two essays a week on them, and reading the books because it's the evening and that's what you do in the evening, is not worth that much.
At the current unusually low prices, it buys you five hundred million barrels of oil, which is a little more than the amount China has so far burned in 2016.
Yes, really high-end tech skills have a substantial market value.
But this means that, if you train people up in-house, they will notice that they now have a substantial market value and they will leave. Until someone developing a billion-item million-transaction-per-second system for HMRC gets paid the same as someone developing such a thing for Tesco, there will be a flow of people from HMRC to Tesco.
Yes; you need to devote a modern computer to being a filter between the scanner and the world. Scanners are staggeringly expensive and modern computers very cheap, so this isn't a terrible problem, but IT organisations seem very resistant to models which treat the symptom when they think that merely by wasting vast amounts of development effort they can treat the cause.
The powers-that-be appear to worry much more about the confidentiality of the data than about its availability.
Frankly I don't care if the consequence of any ambulance-operative in the country being able to discover instantly that I have blood type B is that every hacker in the world also knows my blood type.
And that's why I'm proposing putting the USO on Openreach. They're big enough to absorb the cost of the USO and efficient enough that they can keep charging the same price as Virgin while doing so; and having satellite broadband available as an option to satisfy the USO means the last 0.1% cost Openreach no more than the £1800 per year each to settle their satcom bill (obviously in reality less, since Openreach will have a bulk arrangement with the satcom provider - sadly I suspect the economics doesn't work out for Openreach buying and operating its own satellite)
What is the point of a subsidy which covers the cheap part of the installation and not the expensive part? Give Openreach a full-service obligation without differential pricing, so they have to absorb the price of the ground station and the satellite bandwidth for any place that they're not willing to run wire to, and look how suddenly they will become more willing to run wire.
Planned maintenance would be the problem there; guaranteed breakage, whilst most kit will just keep on keeping on without worrying about maintenance. The servers at a previous place of work went down mostly because of UPS preventative-maintenance or bugs in the device that attempted to determine whether the chiller cabinet chiller had stopped working.
The mains is much more reliable than your average UPS.
Is there anywhere still on a three-year refresh for desktop computers in general? It's just about worth doing for software developers, but for general call-centre users five years ought to be fine and I imagine people are heading towards seven. Laptops wear out more quickly and the good-enough moment for laptops was more recent.
