Creating RAID devices and rebooting twice (once to start using the RAID device, and again to stop using it afterwards) seems excessive here. I do this sort of thing with a script very much like lvmsync:

http://theshed.hezmatt.org/lvmsync/

except that it works on any block device, not just LVM.

If implementing your own script instead of lvmsync all you need to do is dd off the block device while the VM is running, shut the VM down and then dd only the changed chunks. This can be achieved by reading both the source device and the target device, hashing the chunks and comparing hashes to tell if you need to write the chunk again.

You don't care that the source device is changing under you as you're reading it, because all you're trying to do is get an initial rough copy of the data. The final sync with the VM shut off gets all the changes and makes it consistent.

I typically see single digit changed megabytes per gigabyte of active filesystem, so the final sync goes very quickly.

This also has the advantage that it works in any scenario you have a block device, so would work for OP's host connected to two SANs, but also when you have two hosts each with local storage. You can just do it over SSH.

Another thing you can do is to play with xnbd to put a proxy block device on the destination:

https://bitbucket.org/hirofuchi/xnbd/wiki/Home#!scenario-2-s...

That may be helpful if the storage is local to each host and is truly massive, as a VM on the destination host can use the NBD block device and be unaware that it is proxying requests back to the original host for data it does not have.

Eventually the data will all be synced across to the target host and then the VM can be rebooted to switch back to the non-NBD local block device.
Oh man, that reminds me of the 90s. You used to have this situation where certain games required a certain memory configuration (640K / extended memory).

So the first thing I did that ever resembled programming was a boot script that would give you a menu of which game you wanted to play. It would say "1) Beneath a Steel Sky 2) Dune 2 " etc. And they it would prompt you to put the right CDROM in.
Yes, that's entire point of the article.

Because it's their job not to. Lots of people don't want to be found but it's in the public interest to find them.

I'd argue the same goes for the creator of Bitcoin. It's in the public interest to find this person and see what they stand to gain from Bitcoin's continued use and value, and what they are likely to do with the money. You will respond that it doesn't matter, but it does.

What if Bitcoin came from Iran's secret service and it will be used to fund an enrichment facility?

What if it came from a drug lord?

What if it came from Michael Bay and he's going to make yet another Transformers movie with it?

All of these are in the public interest to find out and make people reconsider their adoption of it.

A decision void of context is necessarily an ignorant decision.
Ah, thanks, those threads are great reading. Yeah there's not too much new here, although I was surprised to read that some employees and customers got out, apparently in protest to the pay raises.

There are some interesting variations of the game, using a standard Monopoly set. One I've seen allowed things like Lynch Mobs - if enough of the players agree, they can send someone to prison, remove their assets, or even eject them from the game. You could also institute a rule like "90% tax on cash holdings" or "those with assets under $200 receive an extra $1000 when they pass Go". It sort of combined Werewolf with Monopoly, because it required more skill at the human level to persuade your fellow players to vote with you.
The massive discussion from two years ago is interesting:

Very likely the offer is contingent upon the successful completion of a background check. A thorough background check (criminal, education, credit) can cost a few hundred dollars, so firms won't proceed until an offer has been accepted.

Even though he was exonerated, his prison stay and other convictions may show up. He can explain, but a firm can rescind an offer for whatever reason they want (outside of protected statuses, which does not include criminal background). For a security position firms may want perfectly clean backgrounds.
Cool - data sets around Landsat 8, APOD, Near-earth Asteroids, Mars rover photos, the NASA patent library, even historical audio recordings. Hope they keep adding to it!

Wish they had something for the ISS for example - experiment feeds, positioning, historical activity etc - or is that found elsewhere?

Can someone post the TL;DR (uh....TL;DL?) from the podcast here? Looks like a decent discussion going on, but can't tell that anyone actually listened :-)

I'll cop to the fact that I'm just not going to spend the time, though I'm interested in the conclusion(s).
That's pretty awesome never looked at it that way...
I've had some similar anecdotal experiences in an education franchise, where I've found that it's very difficult to convince boys or girls that math, physics, programming, or computer science is fun or worthy. In fact, I have trouble convincing them that any intellectual pursuit is worthy. Kids tend to enjoy "science" more, but only in terms of what appears to them as fun experiment. When you try to explain anything behind it... it's boring. I'm sure it's similar for the robotics programs popping about.

I am also aware that I am just one more adult voice competing for any child's attention, a noise among a chorus of people all with their opinions about what's important. Boys and girls alike question the immediate value of these subjects. They see them as work forced upon them by adults.

Like you, I have also noticed that the boys and girls of today, at least in middle class areas, often have touch-screen devices as their first device. Those are just game machines with tons of advertisements. I am sure those companies know that they are advertising to kids. The kids love the ads because viewing it means an in-game reward. But that's an aside. The main point is that these devices aren't an obvious portal to software or technical interest.

I have noticed that many schools have a small cadre of children who, by some combination of successful grooming by parents or personal inclination, do enjoy technical subjects and technical mastery. I think at some point, the social reinforcement by that small cadre of children overtakes the importance of parental grooming.
Is there a reliable site for reviews of Chinese Android phones?

I'm tempted, but it's hard to know which are good and which are terrible.
That's not the direction it is taking. It will be more like 1 highly paid developer doing everything himself.

When I started working, it took a team of testers, a team of dba, and a team of sysops in addition of the developers to build anything. Nowadays, no only the development team is smaller, but the sysops, dba and testing are the responsibility of those developers too through automated tools. On the client side, there used to be BA and Testers, but nowadays, BA and Testers are often the same persons.

The tshirt from several years ago "I will replace you by a tiny script" has proven quite true. Old job that required qualified people before have been replaced by scripts, not "blue collar" worker. A huge amount a developer entering the market could lower the salaries, but any simplification to the developer role is going to be handled by automated tools, not human.
In Chile most of the people with power and money are exploiting the land, mining and building hydro power plants, destroying the planet for their own benefit. Douglas is a visionary, we are very thankful for his gifts to the future of the world. More people around here need to be like him. Hopefully his wife will continue his mission and legacy.
Don't bother. Non developers always end up resorting to Email.
Capital gains taxes are way more complicated than this and they aren't only calculated when the asset is disposed off.
Capital gains also are not calculated for individual assets but globally which also means you get tax relief for capital loss if any had occurred.

If you have any capital assets each year their value will be recalculated and compared to last's year calculations (some assets maybe calculated on a quarterly basis) the taxable value is then adjusted for any capital gains or
loss that was carried from previous years and the final amount is calculated so you get a tax invoice "your GC tax for year 2015-2016 is X).

You can pay that tax immediately or you can choose to carry it on depending on the tax law and assets you might have to pay a certain amount immediately you might also be allowed to carry the tax to the next year which also might incur a certain payment/tax on it's own.

If the tax law allows you to carry on loss or gains to following years there's usually a limit to this (e.g. you have to pay the tax every 5 or 7 years to be able to do that) different types of assets will also have different regulation regarding deferring tax payments e.g. directly tradable/liquid assets like bonds might now grant you deferral on yearly GC tax while non-liquid assets like property which requires registration and tax duty to transfer will.

Considering that Australia most likely has laws which will be quite similar to those of the UK (As it only achieved final independence in 1942 or well technically 1986 ;)) there is a good chance that the capital gains tax on BC should've been paid every year, and even if it wasn't and you could deffer payments you had to declare it and submit it for valuation each year for tax purposes because otherwise GC tax cannot be calculated. So no matter what was the value of BC when he made it if he didn't declare it properly especially after it was defined as taxable assets in Australia he violated the law, given his at least presumed intelligence (regardless if he's Satoshi or not) and the actions he so far has taken this was done quite knowingly and intentionally.
I use the plumber analogy all the time, but most programmers I know vehemently resist this notion. I find nothing wrong with being a plumber, and think many of my colleagues would do well in realizing they aren't high flying architects but actually just well compensated plumbers.
The relevant cost for container ships are fuel, not people.

Self-driving container ships don’t run on less fuel and considering the massive size of these ships. For example, Maersk’s Triple-E class ships are manned by 22 people (according to the German Wikipedia at https://de.wikipedia.org/wiki/Triple-E-Klasse).
When I was in NYC last month, Apple Maps walking directions were consistently better than Google Maps. It was shocking. Overall, it's still not nearly as good as Google but I'm much more likely to try both now and compare, than just assume Google is always better.

These accessories command relatively high prices and cater to a market not covered by Lego itself.
So? It's not like the people in Slovenia, Poland, or the Philippines are less intelligent or less well educated than people from Western Europe.
That sentiment might be jumping the gun. I was just a kid playing around with a DEC PDP-11 when the TRS-80/Apple ][/Commodore Amiga wave of personal computers hit homes (I wasn't exposed to the earlier, Homebrew Computer Club-era, MITS Altair/Apple I/Heathkit H8 wave of personal computers). I clearly recall IT staffing at the company where the PDP-11 came from heavily staffed by women. However, even the daughters of those women at that time who I got to meet, to the last one, had zero interest in anything having to do with computers. Except maybe for the occasional game that caught their fancy. Usually storyline-driven themes like On-Line Systems aka Sierra Entertainment titles and Pac-Man clones; they rejected all of the dungeon crawlers or shoot-up themes. I recall even as a youngster thinking at the time the displayed gender preferences very odd, as computers to me were neutral territory where neither gender had an obvious physical or social advantage at the outset.

I am guessing that the early marketers likely observed the same emergent social behaviors, and decided to market to where the money was. Meeting hundreds of people in the industry, it is vanishingly rare to find a woman who bugged her parents as a young girl for an early-era home computer; that story is so common among men it is a pedestrian trope. I'd dearly like to know from marketers who were involved in that era to chime in on what kind of market research led them to tilt the early marketing towards men and boys.

Really very odd graphs of both male and female students. I haven't seen anything that really explains the peaky total number let alone the ratio profile.

Interestingly the higher degrees seem to be pretty stable in ratio terms. Not sure what they may be indicative of though.

Very strange.

I'm not in a big city and not in the USA, and Apple Maps routinely sends me to the wrong place when I lookup addresses.
Maybe people shouldn't rely on it so much but I don't think the service is good enough for safe travel. Seems all that's changed is that it is now dominant. My perception of quality hasn't changed since the 'laughing stock' news hype when released.
I must say, this blog pops up on HN every couple of months and after subscribing for the first few articles I'm STILL not sure as to main crux of his argument.

I understand that he hates the "flat" design trend. I know he loathes the "Californian minimalist". But I still can't quite grasp exactly what it is he DOES like.

His blog posts include lots of images comparing iOS icons to pre iOS7 versions, mostly comparing images without gradients with those that have gradients.

Can anyone actually explain his point? As far as I can make out he seems to be arguing that users would benefit more from design that "pretends-to-be-like-another-thing" rather than "represent-that-thing-as-it-is"; y'know, the opposite of honesty in materials. For the life of me I can't make out if he has a point, or it's just the lamentations of someone who got really good at drawing skeuomorphic* icons and is now buggered because the fashion is now for flat monochrome icons.

* I loathe to use the word like this as I don't believe that many cases that type of design or interface is strictly skeuomorphic, more misplaced metaphor. e.g. stitching on a fake leather notepad=skeuomorphic, detailed drawing of a hard disk drive to represent a hard disk=metaphor
Visual Studio 2015 Community Edition is considered a top-notch programming environment... and it's free.

It would be the perfect place to put something with built in programming hooks into Minecraft.

And... there is already too many people putting too much garbage on devices that people don't need... last thing we need is being loaded down with crap - whether Python, perl or Visual Studios - on a default install of Windows.

(Why the F* is Candy Crap included with Windows 10 now? Much less Note and other crap that should be opt-in... not clean install > remove, remove, remove... /rant)
That, and for me personally also because i avoid Google products whenever i can since i will be paying (for these "free apps") with my privacy. I only resort to Google Maps if i can't find something in Apple Maps.

As far as i'm aware, Apple Maps is only usable for people who payed for Apple devices, which is why Apple doesn't have to sell my privacy to create a Maps app.

Google Maps however, is "free" for anyone to use.
Me too. Well, once per reboot. Even under very good circumstances, Emacs' startup time is worse than mg or vi. And having it run in the background, keeping its state, open buffers, shell history, etc. is very convenient.

What if knives had been invented by a drug lord?

Who cares? What's important is whether knives are useful to us or not.
If the inventor is a drug lord, then the problem is that he is a drug lord, not that he invented knives.

If someone invents something useful, then he should be rewarded, independently of whether he then uses the resulting money to save starving children or to buy Doritos all to himself.

If he does something illegal with that money, then we should come after him because he did something illegal, not because he was able to do something illegal (because he had earned a lot of money).

This was never "Hacker News", but rather "Bay Area Nerds Drinking Too Much Startup Kool Aid".

The only thing that has decreased over time is the number of Lisp related submissions.
Porting it wouldn't even be necessary IMHO, just adapting and stabilizing a few of the in-game programming mods.
I find the premise of this very strange. Is there any proof that the kind of design described really came from Eastern Europe? Or that the most of the authors are from there? From my (brief) visits to dribbble it seemed like that kind of work was popular all around the world.

This just sounds like "Us vs. Them" to me.

Angela Merkel – Person of the Year
Speaking as a developer and as someone who spends a lot of time configuring and using iPhones, this is is not surprising and indicative of nothing. The native Apple apps on iPhones have access to resources we as third party developer's can't touch, and integration with each other that no third party developer can even come close to matching unless we reinvent half the OS. Add to it that the only way we're allowed to make, say, a navigation app is to offer a service that a native Apple app does not (we're not allowed to "duplicate functionality," per the developer agreement) and stories like this mean absolutely dick to me. Of course it dominates the iPhone platform, but stick Apple maps on any other platform and it would fall on it's face.

Better than something like Mapquest? Probably. And the integration tools are great too, as are notifications on departure time and whatnot, but the actual app, judged by it's capabilities is nothing compared to Google Maps.
FileFormat.info probably deserves a mention, given that has pretty much the same objective: http://www.fileformat.info/format/a.htm

>Or rather technical effort and hard thinking were the only way to make that magical screen light up.

This is crucial. A lot of people seem to be suggesting that because it's easier to get into computers kids are missing out on programming. But in reality it's the other way around - only the people who were wired up for engineering could get into computers previously and nowadays everyone can use them - you can still get into programming and plenty of kids still do - and it's easier than ever (I had no internet when I started coding - only the F1 help manual of QBASIC and my below basic English - what I could have done if I had all these tutorials available today :( ) - they just aren't the only ones in to computers so they aren't as visible as they used to be.

Think of it like this - every kid probably had some electric toy car or some such toy in the last 20-30 years. But not every kid took that car apart to see what cool shit he could do with the electric engine and batteries.
Complaints like this were quite regular on the good old "Hacker News" so I conclude that HN is still "Hacker News"
This doesn't surprise me at all. If something's installed by default, that's what most people use.

In fact, I've found that the very idea of using a mapping app to navigate is still foreign to a large percentage of people. If someone is wondering how long it will take to walk somewhere and I suggest they check using Google Maps, I still get a confused look about 50% of the time.
In the UK I've found Google maps unusable for navigation. It will consistently fail to give turnings and exits until too late. On the other hand, the only problem I've found with Apple maps is the weird pronunciation of road numbers.

May I wonder if anybody is making a derivative of (neo)vim with a tiny core and just a few features including vi-keys-combos, auto-indent, searching, piping and unicode support?
The issue is the "maturity" of programming as a complete field. Not only is it a "young" (decades old vs say construction) but it's changing dramatically year over year - whats asked for today is different that 5 years ago... what's acceptable 10 years ago is a deathtrap today.

With that being said, how can colleges REALLY train? I got trained at my local community college a few years back (2008-2010) in VB and Cobol. How fast can most places REALLY respond to a moving target like this?

Also, a degree is no indication of programming skill... but neither is having a job. You can churn out code, hopping from one place to another, and still be a shitty programmer.

That's one of the biggest issues... How can you REALLY tell what someone is going to produce? There are no consistent certification processes and no consistent measure of what makes a good programmer.
So they're selling Alibaba, but doing it the other way around.
I actually make an effort to regularly use Apple Maps in order to fix their bad data, and it still hasn't quite replaced Google Maps for me.

Google Maps is still way better by every metric (accuracy, design, user experience, navigation, etc) except NYC subway entrances.
