120 teraflops using INT8

Er, doesn't the F in teraflops stand for 'floating point'? Or has everyone been talking about flops for so long they've slowly forgotten what the term means? (Distinguishing so clearly between integer and floating point performance makes less sense now than in the '90s)

London app dev wants to 'reinvent the bus'

leon clarke

Small buses

Loads of companies introduced them just after bus deregulation. Strangely they seem to have all disappeared. If you want to drive an incumbent out of business, running loads of small buses make sense; you need to offer a more frequent service and actually carry all of the passengers. The cheapest way of doing that is to have loads of small buses. Once you've driven them out of business, you can stop wasting so much money on drivers by going back to an infrequent service with big buses, just like (or maybe not quite as good as) the incumbent used to offer.

IBM: Customer visit costing £75 in travel? Kill it with extreme prejudice

leon clarke

So...

No travel unless explicitly required by the contract. Suppose you're thinking of buying something from IBM, but you worry that (as happens on all big contracts) there'll be occasional times when a few misunderstandings will happen and need to be smoothed over quickly before the misunderstandings escalate and become a big problem. What needs to happen in this situation is that the IBM guy hops over and has a chat with your boss; it's all sorted out and the proverb continues to be true 'no-one ever got fired for buying IBM'. Now you know that the IBM guy won't hop over until your boss has sent in the lawyers and we might need a new proverb.

How 'real' are Sim-only RRPs

If I read the article correctly, they're comparing ebay second-hand prices to the SIM-free RRP. However, I've got the impression that SIM-free RRPs can be massively inflated. The manufacturers can 'charge' what they like because approximately nobody buys phones sim-only, so losing sales here doesn't matter. (They solve the problem of large markets like India where phones are sold SIM-free by introducing a very similar phone with a different name for a more realistic price) The reason for doing this is because the people will think the phone should be compared to a much more expensive phone (probably the iPhone) as the price is the same, but strangely it's much cheaper when bought on contract (because the real price that the operator paid is much lower than the published RRP). Hence customers flock to the phone as it's 'equivalent to an iPhone' but available on cheaper contracts due to some 'special deal' they don't understand. Or that's the theory; it doesn't seem to actually be working for HTC.

Love lambda, love Microsoft's Graph Engine. But you fly alone

leon clarke

What's interesting to me about Graph Engine

What you clearly want now is a 'database' which is scalable (throw more nodes at it when you need more space or speed), which stores things in RAM but properly persists them to (redundant) discs.

If you've got one of them, it's probable that the CPUs will be under-utilised (since they're mostly there to hang all the RAM off)

So the dream would be something that can do some compute on all those nodes. (Why copy data somewhere else for processing when there's an under-utilised CPU in the same place as the data)

That's what Graph Engine seems to be. And I think it's the only open source thing that ticks those boxes. OK, it's a graph database, but that probably fits real wold problems at least as well as SQL usually does when you've got your head round it.

What else can do that?

Did Oracle just sign tape's death warrant? Depends what 'no comment' means

leon clarke

It's pining for the fijords

There have been plenty of Oracle things (Java, Solaris) that are clearly dead, despite flat out denials. I'd say that 'no comment' is less positive than 'we're fully committed to X but we're re-jiging the roadmap a bit'. And we know that the latter really means it's dead but they don't dare tell anyone.

Re: Opteron killed Itanium

I seem to remember that the original Iantium plan was that it'd eventually totally replace the 32bit-only x86, even on desktop once desktop needed 64 bit. But AMD came along and screwed up that plan. After that, Iantium never really made sense as the desktop customers weren't funding all the development as they were supposed to.

A spanner in the works: Google's cloud database hits beta, gets prices

leon clarke

Re: Cool

It seems to me like it'll scale to really big distributed things, in the way that RDS doesn't.

If you need that, it would be worth paying for.

If you want the Google answer to RDS, that's Cloud SQL, and is priced about the same as RDS

Cool

I can't wait until Amazon or Azure has got something like that.

I really feel that we should be able to have 'have cake and eat it' databases, and we should have had them for some time. Right now, this is a really cool feature which Google has but the others don't have. But even if it's brilliant, I'd feel a lot happier using it when Amazon or Azure have something that at least almost competes. I know that changing cloud provider would always be a nightmare, but I'd feel happier knowing that there is another cloud provider that does have roughly the right building blocks.

And just because I want to have my cake and eat it when it comes to databases (and cakes) doesn't mean I think this is applicable everywhere; notably it isn't a viable foreign policy.

Inside Confide, the chat app 'secretly used by Trump aides': OpenPGP, OpenSSL, and more

leon clarke

I guess this app is being run on a stock android phone

It won't be on an officially hardened one as officially hardened phones don't let you install apps whose security hasn't been approved by the NSA. And their first tickbox is 'is the crypto FIPS140-1'.

So attacking the phones is the other attack vector for this stuff.

I'd be interested to read what mobile games are popular amongst trump staffers. And so would many other people.

Re: "Hate my life"

The challenge is simple to express:

He needs to say 'Mr President, you need to give me your Android phone, which I'm going to put in this metal box. You'll get it back after the 46th president is inaugurated, whenever that might be. Here's your new phone, which only has secure apps on. You'll note that these exclude twitter'.

Assuming Trump says 'no', and I assume there is someone in the White House competent enough to have made that demand, so I know Trump did say 'no', you can assume the president is carrying a bug around with him. In which case, the CIO has failed in the most important aspect of their job.

Google hardwires its Android app store into new Chromebooks

leon clarke

Not sure there's an anti-trust argument

Critical to the Microsoft case was that there was a thriving market for media players that was killed off by the bundling. Hence MS was using a monopoly in 1 market to establish a dominant position in another market. That's what's illegal.

Assuming we can define some 'market' such that chrome OS has a monopoly (e.g. the market for cheap laptops with an OS that's just a web browser), I don't see how you can argue there's a market for 3rd party app stores that would be adversely affected by the bundling.

Splunk: Why we dumped Perforce for Atlassian's Bitbucket of Gits

leon clarke

I really hate GIT

But it's better than all the alternatives.

Once you've got your head round it, it does the right job and does it very well, everything integrates with it, and everyone either understands it or knows that they have to put the effort in to understand it as it's an essential check-box on their CV.

But learning it is a complete git. And I can't help thinking that it would be possible to invent a distributed VCS that did what people want but isn't quite so confusing. But now, if they did then no-one would use it as a critical mass of people understand git.

US Supreme Court to hear case that may ruin Lone Star patent trolls

leon clarke

So if this goes through, everyone has to be sued in their state of incorporation

...assuming I'm following.

The interesting thing is that very many companies are incorporated in Delaware as that's the most tax-efficient thing to do. So it'll make matters better than East Texas. But not much better.

Until some state decides to have uniquely sensible patent policies (My proposed sensible patent policy:'NO') and everyone incorporates there, knowing that the tax is cheaper than paying the patent trolls.

Blu Vivo 6: Top value trendsetter marred by Chino-English mangle

leon clarke

Re: Come back, Nokia 3310, all is forgiven...

Getting phones with multi-day battery life is easy - buy any remotely modern smartphone and turn off wifi and mobile data. I find they'll last a long weekend if you don't spend too long chatting. The reason for the massive battery drain is 2 related things - the phone is constantly talking to the network get get all those wonderful apps to do all their exciting notifications, and you use the phone for rather more jobs than a 3310 was used for. Get a smartphone to behave like a 3310, and it's a perfectly reasonable substitute for one.

In fact, I suspect that phones will always have a battery life of just under a day - if someone installs a better battery, users will install more apps with more notifications until battery life decreases to the point where it becomes annoying, then uninstall the most pointless couple of apps, leaving battery life in an equilibrium state of not quite good enough but not really annoying.

Google's crusade to make mobile web apps less, well, horrible

leon clarke

60% of mobile data travels over 2G networks

..according to the article.

I'd love to see the source for that. It may well be true. I suspect most developers of mobile websites consider bog-standard 3G to be intolerably slow.

If it is true then far more than 60% of users will be on 2G as I'm fairly confident 3G and 4G users will use far more data per person than 2G users

I'd have thought that over 2G, the only chance of a decent experience would be to teach the authors of native apps how to obsessively optimise for really bad networks (a skill that's incredibly rare these days). Getting a web app to perform at that level might be possible but would be even harder.

Cyanogen mods self away from full Android alternative

leon clarke

OnePlus

Massively agree.

OnePlus is a lot more significant than their sales numbers suggest - among technical Android users it's the only alternative worth considering to a Nexus/Pixel. So its influence on important people in the Android ecosystem is massive.

If you were to assemble a team to do something like WileyFox, when you got them together to start work, half will have Nexus phones and the other half OnePlus. So everyone who matters will know about OnePlus's OS and consider it the right way to do non-Nexus android.

Punters want heart-throbs, not brains, when thinking wrist-jobs

leon clarke

Cheap smartwatches

I've noticed that the current generation of very cheap smartwatches sold on Chinese import sites look pretty good based on the website description - Bluetooth 4, reasonably elegant looks, claim to sync all phone notifications, cost around £40, take ordinary watch wristbands. I've yet to take the plunge and get one but I suspect that when the smartwatch market takes off, it'll be devices like these that dominate the market.

They tend to also have heart rate sensors but if I cared about heart rate sensors, I'd restrict myself to devices which have been reviewed by reputable review sites (which excludes all the cheap Chinese devices)

GearBest has a good range if anyone wants to know what I'm talking about. The previous generation now cost around £20 and don't do anything useful.

DCIG mid-market array guide: Why we left those companies out

leon clarke

One wonders about the relative positions of the cart and horse

Was there a secret list of vendors who ought to end up in the comparison, and then someone created a set of criteria that resulted in the right list.

In the interests of avoiding unproven insinuations of corruption, I won't speculate on how the secret list was created.

Private moonshot gets the green light from US authorities

Remarkably small rocket

I had to google the Rocket Labs Electron - it can get 150kg into a 500km sun-synchronous orbit according to Wikipedia. They're one of the bunch of companies going for the small satellite market.

Now I appreciate that a one-way robot trip to the moon will be a lot easier than a manned mission, but it's still impressive that a moonshot needs an exceptionally small and cheap rocket these days.

Questions

In creating a startup culture, where is the venture capital to come from. Surely that'd be helped by doing things that increase the amount of spare money sloshing around in the city, instead of scaring it all away.

Wouldn't startups also want a certainty of access to markets

What are the specific EU rules that prevent the UK from creating a more entrepreneurial state

What reassurances will be given that entrepreneurial high-tech companies will have access to the skilled staff they need? If staff are to come from abroad, how will they and their dependents be welcomed?

Would it be a good idea for a fan of democratic accountability to call an election after becoming leader of the ruling party, in order to give the best possible opportunity for the new PM to answer as directly as possible to the people.

Met cops shop for £150m IT system. Must have: Data centre ops

leon clarke

Re: why?

I've heard the explanation that the Met is the biggest force by a fair margin. As a result, everyone else expects them to go first. Once they've done so, Lincolnshire will discover they have the same requirements as the Met. So they sort-of simulate a national system by the back door. (However, the Met's recent IT chaos has meant some people have got bored waiting for the met to order lots of obviously-needed things and gone for systems that are only as good as a small force can afford on their own)

The other advantage (for politicians in the home office) of a decentralised approach is that the IT cock-ups aren't (technically) actually the fault of the politicians.

So, al in all, a central purchase would be better for the taxpayer.

Linux

A very interesting detail - the root fs is per-user

The linux root fs is contained in a user directory, which presumably means each user gets their own. This may have all sorts of fun consequences, such as allowing the set of mount points to be different between different users, as is possible on plan 9.

Of course I have no idea how Linux users relate to Windows users; if you do sudo adduser, will that create another Linux user in your own private root fs, or add a user to Windows?

Anyway, there are a lot of devils in details about how the 2 systems interact, but it is possible that Windows 10 actually has useful features as an OS for running Ubuntu on which Linux lacks.

The paperless office? Don’t talk sheet

leon clarke

Getting there slowly

Asymptotically slowly.

Now I've slowly got used to having 2 decent-sized monitors, I print out a lot less stuff. Like approximately none. I guess that a typical office now needs quite a small and cheap printer, and with time it'll get smaller and cheaper.

When I retire, I assume it'll be lower-spec than my current home printer. But will still exist.

Now can we kill office desk phones. In a typical office, everyone except the head of HR and the finance guy can't see the point in a desk phone as they just use their mobile for everything.

Spot pricing

One mitigation to the problem suggested is Amazon's spot pricing.

When someone suddenly want 1,000 servers NOW they don't take ones that were running idle; they steal ones from people who had put in low bids for spot pricing. When sensible people want 1,000 servers they don't say they want them now, but use spot pricing to wait until the bank trading floor has finished its 1,000 server 'must be run at 4pm' job then grab all the spare servers.

Encrypt voice calls, says GCHQ's CESG team ... using CESG encryption

leon clarke

CESG's hobby is promoting applications for IBE

(IBE = Identity Based Encryption)

This is an idea that was invented by CESG. It is regarded as secure. It is a very cool concept. It's probably CESG's biggest triumph in terms of academic crypto (ignoring rumours that they invented public key crypto before anyone else because inventing something and keeping it secret doesn't count as an academic crypto)

So CESG keeps on coming up with really cool protocols that use IBE. The only problem is that anything you can do with IBE can be done in a way that's slightly less theoretically elegant but more generally understandable using ordinary public key crypto. So that's what everyone always does.

TalkTalk attack: UK digi minister recommends security badges for websites

leon clarke

Re: Read the PCI DSS and weep

That falls into my 'more onerous than PCI' category. No-one will bother with compliance unless it's made mandatory, and if anyone suggests making it mandatory then some trade association will invite lots of ministers to their long conference in the Bahamas to convincingly explain why it's a bad idea. (The more factual aspects of this presentation will involve remaining competitive with economies that don't have excessive red tape. Funding this trade association's blatant bribery would be much cheaper than complying with such a certification)

I entirely agree that to offer any useful protection such auditing and insurance is needed.

Read the PCI DSS and weep

PCI is both an intolerable pain in the ass to comply with and completely inadequate at protecting consumer's interests. However, when you look at it, it's all quite reasonable, in the sense that if you're going to write a box-ticking assessment standard to prove a system is secure then PCI does about as good a job as is possible. There aren't absurd pointless requirements or obvious omissions.

So the question for any such kitemark is how does it compare to PCI. Is it more onerous, in which case no-one will bother. Is it less onerous in which case it gives no meaningful assurance of anything. Is it the same, in which case no-one will bother and it gives no meaningful assurance of anything.

Where will storage go over the next 15 years? We rub our crystal ball

15 year timescale

Over that timescale you have to assume some sort of technology like X-Point or some other phase-change memory will be developed. When that happens, its liable to be much more rapidly disruptive than flash was. I suspect that flash will look like a briefly-forgotten intermediate technology between disc and phase change. And things will get very hyper-converged very quickly - it's the only way to make use of the speed of phase change.
