This list, or rather lists like it, occur pretty often. See https://techcaption.com/deadly-linux-commands-destroy-comput... (from 2 months ago) and https://www.techworm.net/2016/10/10-lethal-linux-commands-ne... (from 14 months ago).

Thing is, I don't think the authors actually verified that all of these commands are as dangerous as claimed.

POSIX 2008 required a special check for "/". Userspace tools like those in Solaris, FreeBSD, and GNU coreutils had a special check before then. https://unix.stackexchange.com/questions/410759/since-when-d... . On a FreeBSD machine I get "rm: "/" may not be removed". Though I see that BusyBox 1.24.2 lets me do it.

When I try "mv / /dev/null" with Busybox I get "mv: can't overwrite non-directory with directory". On a FreeBSD machine it says "mv: rename / to /dev/null: Is a directory"
Since OpenEMR is open source and supported by numerous vendors, companies, and volunteers, it's very difficult to accurately collect this information. It's downloaded more than 4000 times per month, and the project is confident there are thousands of installations in the US and across the globe. There was an attempt in 2012 in this article to quantify the number of installations:

Awesome list of testing tools, had no idea Stoplight had a test product. Crazy how much faster prism is.
I looked at the next train they were selling a ticket, which was the closest I could come to the flexibility you get on a £182 ($240) London to Glasgow ticket that came close to the "$300" mentioned by the OP.

I've checked again for tomorrow morning, $295. Perhaps I'm using the site wrong: https://imgur.com/TnuOGt3

295/226 is $1.30 per mile.

I'm ignoring the slower trains, non flexibile, booking in advance etc, as that wasn't what was raised. There are slower options for London-Glasgow that are nowhere near the full price (for example £57 tomorrow morning if you go via Edinburgh - saving £130).

I've just checked my emails - last time I took this train (albeit from NY to Washington), in March 2013, it was $498 for 2 tickets - $249 each.

This is for a far less flexible ticket than I get in the UK. For my $240 I can travel London to Birmingham, have the day there, and then continue to Manchester, have a meal and stay in a hotel overnight, then get a train from Manchester to Glasgow the next morning.

Washington to New York is half the distance, and nearly twice the price, as London to Glasgow.
Two machines seems like overkill in this case - why not debug using User Mode Linux[1]? Debugging with two machines makes perfect sense if you are debugging a hardware driver, but not here.

Ask HN: What do you do to make your developers productive?
I've been in a lot of different types of shops. One thing I found in common across the board is no shop really dedicates any time to making sure developers are personally productive.

There might be read-me files and hints at setting up a development environment, but have any of your teams gone above and beyond to make sure that a developer can at least: Run, Debug, Install, Test any component without 1) A dependency on other people, 2) A dependency on a specific location or office or network, 3) A dependency on a shared system where your test data can be affected by others.

But I want to know more - what is it specifically that you are all doing to ensure developer productivity: are you asking them if X works for them? Do you test them? Do you hold training sessions?

I'm asking this question because of all the shops I work at I end up being the guy that makes the build, builds out the core code base, sets up the IDE environment files, sets up Git/Maven/Docker/Architecture/Test Data.

And I want things to go smoothly - it generally does, I think every iteration things are better, but I've definitely noticed most developers don't upstart like this. They don't try to improve, they don't attempt to make sure things are ideal.

Instead they code locally, have no way to test locally, debug locally, have no test data add log statements and commit - connect to a shared environment and see if their shit works.

Part of me wants the world of software craft to start at these basics and then work on the product - I believe our productivity gains would be through the roof, but instead I get to hear day in and day out how everyone is stuck.

So tell me, what does your org do to get this right?
You wrote:

If there was there would be a competing cartel as it is the case everywhere.

Providing two examples of where there are competing cartels is not an argument that this phenomenon occurs everywhere (emphasis originally yours). Your logic is off.
Doughnuts?
I agree with most of your points.

However, I'd like to start with two labor patches (in the same set).

1) Pro-rate all benefits (with 3/4ths of median 'full time' work hours as full time).
2) Eliminate that tip as part of wage 'loophole'.

Tips should still be allowed, but they should be for truly exceptional things, and not a hidden cost of buying something.

If you think heuristic contradicts “intractable” You don’t understand the meaning of the word.

Intractable problems can be solved sometimes, just not reliably or in bounded time. If we get to the point where self-driving cars depend on human-encoded rules for reaction, we’ll simply be trading one set of messy heuristic behaviors (people) for another (robots with bad sensors and limited domain awareness).

Will the automated systems be “better” with enough time and investment? Perhaps. But dreams of a fatality-free automobile future will remain science fiction.
Alas, it seems OpenStack is still in the gutter. :(

It's a mindboggingly strange mess. Yeah, it works, when it works, but it's so undebuggable and unmaintainable. Well, if you have in house committers from the core projects, then you can afford to run custom forks/branches. Oh and a few dedicated Infrastructure Wizards deploying it, upgrading the components as patches land, managing outages and simple gotchas.

It's almost easier to roll a new non-multi-tenant instance for each tenant than to try to make it multi-tenant as both Horizon and Neutron are bad at handling domains.

And it [one of the neutron linuxbridge agents] sometimes randomly eats IP addresses from host interfaces :o

Oh, and the docs and release notes are still generally useless on compatibility changes, upgrade procedure and so on.
So, mind showing me what firms are making multiples of that?
I'd like to also point out tig.
"Tig is an ncurses-based text-mode interface for git"

It doesn't have all the bells and whistles of a GUI, but if you need to look at all the branches, and commits to a repository. tig is an excellent tool. tig doesn't issue any commands though, its only a browser, you'll still need to know the CLI. (essentially a ncurses version of gitk)

I'm normally in a ssh session on a remote box where my compile & run cycles happen. tig is curses based, so no X11 needed, filled in a really nice itch of mine.

Then no one needs to map the road anyway, why bother?
I would say before algorithms started showing us different content even if we are subscribed to the same feed(s).

DRM is hardly a problem unless you're using a handful of products, unskipable ads were hardly a problem before smartphones and their market stores took off, and spam was there since the Internet started.

What is new is that Facebook, Google, YouTube, Snapchat, Instagram, and increasingly Twitter are all showing us different content, and our personal preferences (things we follow) are increasingly irrelevant to the information we're receiving.

This all happened in this decade, and this is the decade where we started to fix instead of improve the web. I would point the breaking point somewhere around 2010-2011, when Google, YouTube and Facebook all decided to personalize the things we see.
Doesn't really make the interface any less crap; though I've yet to see a GUI that didn't shell out to the command-line interface (which almost always makes them very unreliable).
It doesn't have to hydrate the parent object, just use .only('relation_id').

Span<T> is safer than ArraySegement<T> as it only allows access to a window of array, rather than full array with a "request" to only look at offset->length

Span<T> is better than Array as it also comes with ReaOnlySpan<T> for a view with readonly array elements; whereas Array is always read/write.

Accident site: just west of the Mounts Rd, Old Nisqually exit on southbound I-5 [1] and streetview [2].

Some additional facts, without speculating about cause: the derailment occurred in a left-hand curve -- running timetable southbound, map westbound -- with the latter portion of the curve situated on a bridge above the southbound lanes of I-5. The curve is at the end of a nearly 9-mile stretch of (freshly upgraded) track with long straightaways and gentle curves. The upgraded section of track ends just around 150 yards from this curve.

In the aerial footage of the scene, you can see the lead car and the carriages following it flew off, tangent to the curve. The middle of the train bunched up on the bridge, and the rear half of the train fell inward into the curve.

Yes I didn't mean that the disclosure was the problem. It's the incentivised reviews that are the problem because you really can't give an honest opinion even if you want to. You didn't pay for the item like a normal reviewer and you have an implicit incentive to give a good review so you aren't reviewing from the same point of view as the reviews people actually want.

It's the same reason many companies have policies that employees can't accept gifts. In theory they could have a rule "you can accept gives but don't let it affect your decisions", but people aren't robots. You can't turn that off.
It's not just fun, it's really practical.

Every time I have to wait days to transfer money between Robinhood, my bank, exchanges, etc.. I'm reminded of the value of crypto currency.

Wire transfers and moving money internationally has higher fees and is more complicated than sending crypto.

Also I don't need a bank account to store it. I don't need to go through middle-men like paypal, venmo, visa, etc.. to send it.

The biggest problem with crypto right now is not enough people/business are using it so we have to currently exchange it to/from USD, etc.. Also the crypto of choice (bitcoin)'s parameters aren't optimal so something like litecoin is more practical.

> I think anyone who uses the CLI is either trying too hard or hasn't realized the beauty of a git GUI.

Nah, it’s just a lot easier than you make it out to be. GUIs are fine too, but if you read the documentation and don’t just memorize a fixed set of commands there’s nothing dangerous, slow, or inconvenient in going about a standard workflow using the CLI.

And yes, lots of people don’t have time for this. Totally okay. Don’t generalize to “anyone who uses the CLI is trying too hard”.
Did you mean Hummer?
Not every way. Flat bottomed woks suck. Gas is much better for a wok, and a wok is a considerably better tool than most westerners realize.

Induction also is easily breakable. That's why you don't see them in commercial kitchens much.

Also I have several large cheap Aluminum stock pots that I love and would have to replace. Try finding a five gallon induction capable stock pot at your local restaurant supply store.
They are kind of the opposite of each other. Slow cookers are just that: set it in the morning before work, come home to a slow-cooked bit of meat and veggies. Instant Pot and pressure cookers in general rely on the fact that water under pressure boils at a higher temperature than at sea level pressure, so it cooks things faster. For example, lentils might take 45 minutes on the stove, 10 minutes in a pressure cooker.

In summary, slow cooker->I’ve got time to wait, make the meat fall off the bone; pressure cooker->45 minutes for lentils? Who’s got that kind of time?
I think there's something about the way you go into a tunnel, travel down it, and emerge somewhere else. They almost have a hint of magical matter transportation to them, ridiculous as it seems. That's what makes tunnels in particular more exciting than mere mines or caves. I can make a cave system immediately more intriguing if I tell you that if you go through the system of caves you can emerge somewhere completely different.
> Do people really believe that infrastructure is not the purview of the government?

Sure. Lots of people do. Japan’s railroads, subways, and many highways, are private. Water utilities in France are mostly private, as are most of its highways. Almost all electrical systems in the US and Europe were privatized in the 1980s and 1990s.

Would public internet infrastructure have been better in the US? Our internet speeds in the US are faster than our big EU competitors: UK, Germany, France, Spain, and Italy. That’s pretty much the only piece of infrastructure you can say that for. Our subways aren’t better. Our roads aren’t better. Our regional trains aren’t better. But our internet service is better.

It’s not a philosophical question, but an economic one. How do you ensure adequate spending on very expensive infrastructure. Japan does it for rail by making rail companies private and allowing them to use land grants to enter retail leasing markets. (Japanese railways own lots of the land around stations and are the landlord for the associated retail establishments.) Many European countries have the political discipline to ensure adequate funding for public infrastructure. Both models can work.

But we already know that in the US we don’t have the political discipline to properly fund infrastructure. Infrastructure gets attacked from the right, who don’t want to pay taxes. But it also from the left, who want to use infrastructure as leverage for social issues. For example, in Stockholm, the publicly owned (but completely privately funded) dark fiber utility took 16-17 years to cover 90% of the city. There was no mandate to build in historically disadvantaged neighborhoods or anything like that—build out was based on demand. That approach is completely illegal in most US cities.
Here's another video about the situation: https://www.youtube.com/watch?v=An8LJ_fv0mo

I think it was Atty. Kim's project. And while I think the piece has some valid points, I think the 'conservative' political bent does the work some disservice. I watched it with a Korean friend, who actually tapped out early.

Anyway, and this is key to my longer post above, Koreatown was viewed by 'politicians/the affluent' as buffer zone. As is shown in the video, the police didn't respond to the looting here-- because the hope was that the rioters would effectively tire themselves out and avoid the 'important' areas.

No one really cared that rioters pillaged their own areas...
There was moderate concern about Koreatown, but as it was in close proximity to the heart of the riots AND the concern of a group of political insignificance, they too were expendable.

'Divide and (keep) Conquer(ed)' is part of what social and urban planning is all about.
That's pretty much my take on the Kochs as well. They seem to contribute to things they believe in, which incidentally includes public radio stations and hospitals [0]. You may not like their politics--and many do not--but so far everything I have read or heard about them supports the notion they are sincere in their beliefs.

The problem is not so much the Kochs as the fact that we've permitted a political system to arise in the US that allows a disproportionate amount of wealth to flow to a relatively small number of people and to allow those lucky few an outsized influence on the evolution of said system. Those two things are not unconnected.

We use a third party in this case so from the accounting point of view we are receiving fiat currency. Regarding volatility, yes, we are exposed to volatility which until this point is less than the spread between the real exchange rate and the bank one. But obviously there is a risk associated with unexpected events.
I think you've put your finger on the schism of why so many git users prefer a GUI. The built-in porcelain is stupidly inconsistent and confusing. And yet, git's underlying model is so simple and powerful that I think it's worth suffering the bad CLI just to be more fluent and able to utilize git's power fully. The model itself is very easy to grok, it just takes some time to memorize the various random incantations and occasionally look something up, but I don't consider that a big deal for a core tool I use every day.
Right, so you're trusting the miners. Got it.

Sadly this problem /can/ only be solved by coordinating funding at the national level.

I'm still for localities experimenting with what the most effective use of those funds are, but when it's cheaper to ship the problem somewhere else that's what's going to happen.

People discussing Bitcoin's cons are typically downvoted away by the same people yelling "HODL" and spewing various unhinged, delusional predictions about how a single Bitcoin will eventually be worth more than the US GDP. Because there are so many greater fools buying at ATH then trying to create more of themselves to avoid being the last one off the bus, it's pretty difficult to find an internet forum where it's possible to have an honest discussion of Bitcoin's pros/cons.

Right. And the point of my test is to test fake spotting algorithm by finding product that is highly unlikely to have fake reviews.

Thanks for the list of resources--I've been struggling to find good information about whether to use swap.

As it stands, there are 16 links, and I'm anticipating slogging through them, with no idea what I'm getting out of it.
You’ve been able to short bitcoin on okcoin, bitfinex, bitmex either via margin or through futures products for years.

Secondly, newly launched futures products will have very thin liquidity due to the lack of market makers. There is no way a short/long position on CME will move the market in a meaningful way for a while.

I wish Bloomberg et al will stop repeating this “you can’t short” meme because it you can and you could for years.
