It should be enough to copy partition table and boot loader only once. After that, it's safer and probably faster to backup with consistent btrfs/zfs snapshots. Copying raw blocks from a writable mounted filesystem will lead to inconsistent backups.
The Kate Greenaway award recognises excellence in illustration in children's books. I made a list of most of the winners here:

http://danbc.neocities.org/index.html

The official list is here: http://www.carnegiegreenaway.org.uk/greenaway/

Some of these are out of print. Some are definitely showing their age.

Once you know the winning illustrators you can find their other books; or the other books of the authors; or the other books of the publisher.

Sadly these are just books in English. I'd be interested to know if there are equivalents for other languages.
Yup. I seriously do not understand why electric utilities do not do variable pricing to consumers. Do it, and the 'problem' of electric surpluses will go away.
Lesson for government: Software is not a typical infrastructure project (e.g. bridge). It is almost impossible to specify all requirement upfront. That's why waterfall methodology is prone to spectacular failures.

Training government officials how to manage those project can help, but I doubt it will make a difference. It can rather give false sense of "fixing it" without actually fixing it.

I would rather focus on hiring competent ppl and give them freedom to do that right. Such as: https://www.whitehouse.gov/digital/united-states-digital-ser...

Interesting. It reminds me of how (simple) compression schemes save disk space and speed throughput on modern database systems. Moving data around the memory hierarchy is the bottleneck in all systems it seems, from registers, via cache, RAM, (soon x-point,) SSDs, all the way to spinning disks and indeed offsite storage. Some form of space optimisation seems to pay off both ways across this hierarchy even if it is more compute intensive. It was not always so: in the 90s and earlier, compression tended to have had a speed tradeoff.

Agreed that it is preferred way, after raw dd with unmounted filesystem. But I need to be prepared for that: I am a human, I can forget some steps. Here command takes only two arguments (src and dst) -- simplicity is reliability against humand mistakes. Some data will be corrupted, but with journaling filesystems or something like ZFS this is not dangerous (unfinished transactions will be ignored).

I wonder what kind of CA-related worker would think "yeah, google.com is a good test domain". You have to be really not paying attention to think that makes any kind of sense.

Looks like they should look at who stole the money.

Even a very generous 100 engineer team paid at 300k/year for 3 years only costs 100 millions.

He makes some excellent points, particularly this one:

> And so, in the face of a relentless race to the bottom, users are taking control, using a sledgehammer to block them all. It's not easy to develop a white list, not easy to create an ad blocker that is smart enough to merely block the selfish and annoying ads. And so, just as the default for some advertisers is, "if it's not against the law and it's cheap, do it," the new generation of ad blockers is starting from the place of, "delete all."

It also slightly reminds me of what happened with NSA's mass surveillance. The NSA wasn't content to just spy on dangerous targets. It decided that if it's easy enough and cheap enough to just collect it all, then they should just do that.

Now that people are finding out, the government's "encryption kills children!" argument is falling on death ears (as it should). Now people want not just encryption, but end-to-end encryption that make it impossible to do mass surveillance anymore (which is really what they're pissed off about - they have plenty of other means to do targeted surveillance by hacking people's devices so E2E encryption putting a stop to their legitimate investigations is a lie).

well I take 'written in go' is more than a warning than a bonus at this point, especially after looking at some similar tech and finding all this https://github.com/syncthing/syncthing/issues/9 (ended up using glusterfs in the end)

besides, this lib only cover one sync scenario and only one and does it only on demand. might be fast because it stores the hash somewhere, but that also means you'll run in issues if the mirrored slow drive content changes by any mean.
For home customers?

There's usually some cost differences for night/day time (or winter/summer) depending on your contract

Now, to have variable pricing for home customers I think the complexity outweighs the advantages (as in, limited capacity to enjoy momentarily cheaper prices)

I built a game around this recognizer ("Magic Touch": https://www.youtube.com/watch?v=Ze9k0lseb-8 ).
It's a very neat way to do shape recognition in real time. It's very well suited for mobile devices although it's far from being perfect. The interesting bit was to make the recognition lenient enough but still good enough to recognize the shapes accurately. Think about the difference between a 'V' and a 'U'.
Anyway I would love to see more real world uses of this clever recognizer!
It sounds like the people hiring the contractors didn't exactly do their due diligence.

> unclear who is really in charge, sometimes it's no one

> vague deliverables from people who don't know what they're talking about

> tons of cash, regularly, with no end in sight

Sounds like an incredibly profitable and easy contract. It's an ethical grey area, but it's not surprising that companies took advantage.

While this isn't exactly unreasonable, I don't see why it's such a slam dunk compared to "whoever is supposed to look into it is lazy" or "there is no one who's supposed to look into it".
So true! Give us some comparisons as to what these large numbers actually mean. Otherwise it's just jabbering.

Well, a good PC case fan does 160 CFM. A $200 Honeywell air purifier can do 300CFM. So a million cubic feet/hour (16,666CFM) is 55 of these little purifiers.

Furthermore, it's recommended that air be changed a few times per hour, even for residential use[1]. MSG is 10,800,000 cubic feet, so you'd want over 30 of these towers to keep the air lightly clean in there.

Amazon has an eletrostatic purifier that does 1000CFM, so 1/16th of this tower, for $330.[2] 30-1/4 by 24 by 12 inches, so probably still doable in the same volume as the tower.

But this tower looks a lot cooler, making it worth an article I guess.

Ask HN: New Research Papers on Data Structures and Algorithms?
Hi there, I was reading lately the EPFL papers on Array Mapped Tries and HAMTs (Hash Array Mapped Tries), and I become really curious to know more about new researches in the topics of Data Structures and Algorithms. Where can I find such papers and related discussions?
Actually, now that I checked, they don't have one. They apply the DMCA though, so if you think that my reading your comments here is violating your IP rights, you can ask them to take those comments down:

Besides that, [1] applies.

Regarding ad-supported websites, they have their copyright policies and you should respect them (if you care about having their rights respected as much as you care having your rights respected, of course). If you choose not to respect them, it's your free choice to do so and bear any possible consequences - as it is my choice when I don't respect copyright laws, which happens frequently enough, but with my full knowledge that I'm actually violating the rights of the original content creators, and also, in that case, breaking some laws...

I agree, compression becoming 'free' or 'better than free' is counter-intuitive and yet it can be a performance improvement. Perhaps we may see another change in priorities in the future though, as systems optimise more and more for power consumption over raw speed...

(There are SSDs that do transparent compression/decompression. I wonder if there are RAM chips out there that do the same thing for performance?)

To be fair to ARM, their original decision to stick to fixed size instructions was probably correct at the time, when the limiting factor in performance was entirely CPU, and memory speeds were not so much a bottleneck.

Seems like a very different situation here in the Netherlands. Most people live somewhat close by, within 15 minutes of biking, and its not at all unusual for everyone to show up with some drinks or snacks. This takes care of two of the main reasons the article claims Americans are not having a house party.

At one point in the article someone said that only have a 400ft space, and can only host 5-6 people before it gets crowded. I was just at a gathering yesterday in a room of less than 16m^2 (172ft^2) with 12 people without a problem.

It can be set to change when the price is cheapest (on a short timescale, not just an off-peak price) and also to try to minimise the carbon used. It does depend on the local utility offering rebates, but it's often in their narrow financial interests to do so, so the incentives work out.

See also Ice Bear (and competitors) for air-con that stores cheap electricity as ice.

This generally falls under "smart grid" and "demand management" and well designed electric grid markets like in Texas enable these companies to respond to the market price signals.

I find it highly unlikely they'd make much impact outdoors. 1 million cubic feet/hour is 16,666CFM. Wikipedia says a Manhattan city block is 264 by 900 feet. So even if we assume 10' ceiling (so 2.3M CuFt) and little airflow, we'd still need several of these towers to clean it. Except outdoors are higher than 10 feet, and even light wind (avg in NY is 9MPH) will replace the air several times an hour.

More realistic are small filters like this one[1] where you have a relatively limited semi-enclosed space the air flows around. So perhaps in, say, small pavilions and seating areas in a park or something, it might be slightly useful if the surrounding area is rather polluted. But sticking a few in a "filthy rich neighborhood" isn't gonna accomplish much (apart from making money or making people feel smug).

Maybe on a city-scale, using real industrial-strength devices all over would work. But one would assume that cities with smog issues must have already looked at filtering systems and there must be some serious limitation or they'd be deployed already.

Usually how this is done is that you get a cheaper tariff and give up some level of control, e.g your air-con might be shut off for 5 mintues (along with 100 of your neighbours) to respond to a demand spike elsewhere.

Majority of AWS us-east-1 down/having issues, Heroku included
DynamoDB has been down for about 25 minutes now and has taken other services with it, like Lambda, Cloudwatch, EC2, ASG, SQS. I'm assuming the 503's on Medium, TheNextWeb and The Guardian are related. Lots of people on Twitter confirming.

AWS has updated their status page to say they are looking into increased error rates on DynamoDB and increased APIs errors on EC2 as of 3AM PDT.

Full list of services affected:

* CloudTrail

* Cloudwatch

* CodeCommit

* CodePipeline

* Config

* Directory Service

* DynamoDB

* EC2

* Elastic MapReduce

* Lambda

Sorry, I meant that CRISPR is helping people design much faster. Hopefully it will open the door for more people to design and use it, but I don't think DNA synthesis is the real technical bottleneck for new ideas here. Current cloning techniques seem to be fine tools, but I'm unaware of immediate research questions blocked by printing huge amounts of DNA any faster than current methods.
Variation and unpredictability are two different things. It varies by geography, but often wind is stronger at night and in the winter but that is different from minute by minute variation, which is what can be reduced by building lots of distributed wind farms.

Solar, for example, could be said to have infinite variability since its not available at night, but its actually fairly predicatble if it is spread around geographically.

We're seeing the same problems with DynamoDB... it started around 2:20 AM PDT (1 hour ago). We're not having any problems with EC2—what kind of problems are you seeing? I hope it's just affecting the API and not running instances.

Side note: Medium posted an article last week about how most of their data is stored in DynamoDB, so I'm sure the Medium outage is related.
Well… there's other issues than just making code smaller, the idea with having a fixed length instruction size is making the decoder simpler.

Decoding enough instructions to feed a wide issue machine is really hard on x86 and can require loads of power due to the ISA, while if you have fixed or semi-fixed size instructions (like thumb), it is much easier.

You can design ISAs that are made for wide issue, cheap decoding, and compact encoding at the same time, but unfortunately it required asking questions that just was not available to the MIPS/ARM/x86 designers. Out of order execution superscalar processors just weren't invented yet.
