Ask HN: Are there any valid psychometric tests used in recruitment?
I've seen Myers Briggs and DISC assessments but neither seems to have much evidence behind it.

Are there any reliable, valid, peer reviewed, and widely respected personality tests which may be of use to employers and employees?

Or is it all just bunkum?
Not saying there's a cost-benefit analysis to be done, but there's a pretty nonlinear jump from under 100% to 100%, however. In my experience existing tooling for static analysis on C and C++ tends to be it can point out a lot of bugs, but it can't prove that there's are not bugs (of a particular class). This helps me catch things I miss, but it doesn't free me up from worrying about them (X% safe doesn't been I don't have to worry about X% of the code, which would be great, it means all of the code has a (1 - X%) chance of containing a safety bug, which is far less useful).

This cost-benefit analysis also is substantially different between switching an existing codebase and starting a new one. The fact that Mozilla considers it worthwhile to switch an extremely large C++ codebase to Rust is worth noting.
Apple's iChat was an AIM client, until they dropped it for iMessage and screwed the existing users.

News publishers are subject to a certain degree of accountability.

When Facebook launched the real name policy and its limited scale ensured a certain amount of accountability.

These days with advertisement, constantly changing algorithms promoting user content and global scale spanning all types of legal frameworks and enforcement bodies there is no real accountability. Facebook is a tool with incredible power and access to the power is poorly guarded. Zuckerberg may be all powerful but even worse he is enabling anonymous bad organized actors to wreck havoc. An accident that was waiting to happen and of course it did.

The iMac is actually stupidly easy to open, I had to replace a fan on one recently - got the fan on ebay for very cheap, then used a plastic guitar pick to get the glass off the screen(it's held by magnets so you need to wedge something between the glass and the case to separate them) - then used a normal screwdriver to release the 8 or so screws holding the display itself and voila, the whole thing was open and easy to work with. It looks scary but actually it was super easy to repair.

Nobel awarded to three Americans for discovery of ‘clock genes’
I've noticed that posts tend to be more technical on Lobsters than on HN. For example you'll rarely find posts about gravitational waves or medicine Nobel Prize (to take some examples in the current HN top posts), it's more about programming, software, technical stuff.

Quality is good in general both in terms of posts and comments, so it's a good complement to HN.

A chinese register agent contacted me, informing they can register US company for me and open East West Bank.To open the account, I should go to their china branches and do necessary, and they can make USA account.Frankly, i don't know if they can manage the account 100% successfully, as i had bad experience in opening offshore account for my island company in mainland China. A very bad condition is China policy changes from time to time, making businessman insane... That's why I want to make a US company with US account.

Amateur extreme. Pro's need a machine that can evolve over time. More memory, larger storage as it becomes available, God forbid - a faster cpu. Remember the PC platform is inherently upgradeable. The LGA2066 chipset can be used with 8+ different CPU's. Pro's invest in proper tools to support their work, not in souped up toys. Without offense meant to my Honda bretheren, this in the same line as the $100,000 Civic mods. You certainly can, and it will be cool, but possibly not the best use of that money.

Its attractive because of the top end features. But they come in trapped in a disposable package. While that would not be terrible for $300 laptop, it is a piss-poor investment for what 9to5mac says will be a $17,500 top of the line box. Why? The instant one of the features is offspec,too little, to slow , you have an entire $17,000 machine that's too little, too slow.

And no mic input? Why? That's just silly. It cost them more to leave that out.

It belongs with Pro-Racecars, with prepacked engines and hoods welded shut, and with Pro-Lawn tools with no serviceable parts.

Great achievement to have read so much code. Honestly, I felt a little depressing for not having read this much code.

As an aside, how do you read codebases? Do you read every single line to understand what's going on? Or you get general idea about design/architecture? What are the proven strategies to read code bases?
Yes!

Who is hiring product managers? (October 2017)
There was some discussion on the very same for an Ask HN[0]. Copying my comment from there I've found the google/leveldb[1] source code to be immensely educational, authored by Jeff Dean and Sanjay Ghemawat. The implementation of leveldb is similar in spirit to the representation of a

Okay, looked a bit into this and this piece of code is only run if an unsupported browser is detected, which is one of three cases, Mobile or Safari or a non-WebGL enabled browser.

I guess if you're not on mobile or Safari, then your browser doesn't support WebGL and you wouldn't be able to run it either. Sorry!
What size images can it generate? I've used other libraries that can't go past 800x600.
Of course, you're right that what mathematical structures are the equivalent of the everyday terms we're talking about here depends on exactly what we're trying to accomplish. (Though note that the definition of trapezoid versus a square inherently makes use of lengths or angles hence implies we need to be working on geometric and not purely topological structures to be able to make any statement about trapezoids that are meaningful. I.e. a trapezoid can be the domain of a covering of a torus but only when we are interested only in the topology and not the geometry and hence only when "trapezoid" is indistinguishable from "square.")

Yeah coverings can't be isometries (unless they're trivial), but they can always be local isometries which is what we'd most likely want here. R^2/Z^2 is (isometric to) a flat torus, which is, I'd argue, the nicest (though not the tastiest) torus. (Though the question of which flat torus is nicest is another matter and many would say it's not the torus that comes from the square!)

I don't know of any general statement for you about what pulls back by coverings but in general anything you can describe as "local" pulls back. That's pretty vague though, sorry!

You can also build tiny (compared to the PCs 5-10 years ago) powerhouses thanks to the rise of enthusiast mini ITX boards and SFX power supplies. My new tower is small enough to fit in a backpack, but it can fit a full size reference video card, 4 2.5” drives, and the motherboard has two M.2 slots.
Which is why nobody really uses furlongs anymore but there are plenty of other units that are still in use. One example I think we're all familiar is the 'Rack Unit' for servers (i.e 1U, 2U) where 1U is 44.45mm. I don't think there would be any additional clarity gained by saying, "I bought a few 88.9mm servers".
Micro segmentation in the cloud native world
At that time, there wasn't much commercial interest in having e-mail fragmented. For messengers, no company wanted to give up their users and their things. For a while, multi-clients like Pidgin, Miranda or Trillian sort of fixed that for users, now we pretty much seem to be back to darker ages in that regard, thanks to tons of messengers being based on "one mobile device per account" models.

You see some of that with e-mail and development around it as well (webmail for more features instead of clients and protocols, ...)
I don't think we'll see the N64 classic for a while. What makes the SNES stand out even today is that it's home to some of the most well-designed 2D games out there. Games like Chrono Trigger and Super Mario World are still relevant today because on how on top of their game their devs were.

N64 on the other hand, doesn't have that. It very clearly shows that the N64 era was a time where everyone was still struggling with 3D. Few games have a decent camera system, animations are poor, framerate is choppy, fog everywhere, etc etc. I obviously can't speak for everyone, but I can't sit down and play N64 games for that long of a time, they just haven't aged well because of those technical shortcomings.
Elasticsearch learning to rank 1.0 RC1 released
I use gitflow because it helps split up my development work from others on my team that need a code base that Just Works (tm). I want them to be able to checkout master and have no issues. From this point of view, my colleagues are also my customers, and I use master as a release branch - this is beyond all else, most important for me.

Further, it makes sense to have separate 'feature' branches coming off of develop that can be experimental in nature and scrapped at any time instead of rewinding the develop history to a stable point.

EDIT: I mean to split it up for my colleagues because they are not in primarily code-related functions and don't need to be editing the source.

AI to Help Power Grids Resist Disruptions
Theoretically, for this algorithm, there is no size limit.

Practically, if you select something too high, your browser will die for lack of memory or you will grow old waiting for it to finish. My crappy 4GB RAM laptop can only handle around 300 x 500. Try setting the size to maximum, and if your computer can handle it, I'd be glad to guide you in using bigger images.

Show HN: Simple and efficient way to show information about Memcache
Linux is getting better as a desktop OS. I hope that continues so Apple gets some competition - Marketing an all-in-one as a Pro machine is just arrogant, I don't care whats under the hood the form factor is wrong.

I have been using mint 18 with cinnamon 3 and its a nice GUI and rock solid stable. It runs my dev env but also 24/7 servers and a few daemons. I just added some more ram for cheap (up to 24GB ) to run more docker containers.

Its hard to see how I could mirror this on OSX without spending a small fortune. I also own a macbook pro but due to donglegate its mostly for browsing the internet and light tasks (which i guess is what most apple products are designed for these days)
I think part of it is that the newer generation of developers seem to think in terms of frameworks etc as building blocks. Most of the time the solution is orders of magnitude simpler.

>> ... too energy intensive

This argument has become so triggering to me. When I hear this, two things become immediately clear to me about the speaker. They do not recognize the vast economies of scale of a network secured by proof-of-work. They also do not fully understand Bitcoin's value as not only as medium of exchange but also a STORE OF VALUE.

The total number of Bitcoin addresses is 2^160. Yes, the Bitcoin network is currently securing 1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976 payment addresses. That's enough for each person alive on this earth (~7.44 billion in 2016) to have 196,385,600,286,334,710,857,791,565,804,391,698,421.92 separate bank accounts that all fit in your pocket.

How much energy do people think it would take to build a bank (or group of banks) that could collectively account for and secure the wealth in 2^160 bank accounts? Don't even consider that it needs to be accessible from all over the world. It would take A LOT OF ENERGY! Now, how much more energy would it take to also run a payment network on top of it? It would take EVEN MORE.

What I want to know from everyone who cites this tired old argument is this. Just what is an acceptable amount of energy to secure potentially all of the wealth in the world?
Interestingly (and IMHO unsurprisingly) org-mode does this correctly[0]. Footnotes are identified by 'fn:' and a unique token (of course, numbers are unique tokens); they can be easily inserted with C-c C-x f, and can also be renumbered — including normalisation.

I reminded of this discussion from a week and a half ago: https://news.ycombinator.com/item?id=15321850

IMHO org-mode is, as the original author puts it, 'one of the most reasonable markup languages to use for text.' I suggest that rather than trying to improve Markdown, folks just use org-mode instead.

If setting up notifications is "real-time analytics" I need to rewrite parts of my resume.

If your notifications are issued based on aggregated metrics (e.g., the number of incoming cases grew 500% in the last 15 minutes) then you probably could. If your notifications are issued on someone’s action (e.g., user submitted a case) then that’s another level of complexity.
Wat. The Central-West region of Brazil which is primarily agricultural produces less than 10% of Brazil's GDP. I'd say given the possibly disastrous local climate consequences from destroying most of the Amazon, and similar total area, we could say that at absolute best case we might achieve a similar gain. Which would grow our economy by at most 10%.

Destroying the world's most biodiverse ecosystem (seriously, read some statistics on number of species in the Amazon -- it's mind boggling) to grow the GDP by 10% is not just incredibly selfish (supposedly exchanging a global treasure for national gain). It's not even the best for our own interests; it's myopic, greedy, inhumane. Even the actual direct economic value of scientific research with industrial applications such as biomimicry research, plants with applications in medicine and food industry, etc. would completely dwarf a one time 10% gain. And then there's the hardly measurable value of lost knowledge and natural richness.

Don't be the child exclaiming "But my brother was greedy too!". This is our treasure, and our responsibility.

This is a perfect example of the nirvana fallacy.

Advertising on Facebook is a specific, paid mechanism for delivering messages to an identified target audience segment, that is completely distinct from their social content sharing features. Heck, you might not remember it, but there was a time when there was no advertising on Facebook at all.

Regulating that specific mechanism is well within the purview of the FEC, and can be done without interfering with the ability of Facebook users to share content with their own network of connections.

Experimenters don't do their work just to verify theories. (Source: I'm a theorist, but used to do experiment.) They built these 'telescopes' because they want to observe the world via a new medium. They're going to be doing cutting edge astronomy with them for decades.
(I'm a Ph.D. student working on LIGO)

I think the author is missing the point a bit. LIGO is an observatory, and as it gets more sensitive, we certainly hope to see GW detections become normal!

It is already interesting and surprising that the universe contains so many intermediate mass black holes. This was unexpected, and our continued observation of them means that they are unlikely to be a statistical fluke.

Others have mentioned that LIGO also searches for other source types, like neutron star mergers, continuous GWs, and core-collapse supernovae. Assuming our predictions are right, these will be exciting to see, but eventually some of those observations will become routine.

However, you still gain a lot of information from routine observations! Routine observations let us start understanding the statistics of phenomena, which lets us figure out things like how common black holes are and when they evolve in our universe's history. It doesn't sound as sexy as a new discovery, but it's the kind of stuff you use to brainstorm and test new cosmological theories. You need it in order to do real science!

I'll also add that, as a new type of observatory, LIGO and Virgo are like an entirely new sense. It's like we can hear the universe all of a sudden, and our hearing is improving with time. What is really exciting to me is that we will most likely see things that nobody has predicted yet.

>These people care about expandable and replacable things

Apple likely has data that says there are enough people that don't care about these things to justify their production of this computer. I work in an office full of designers, illustrators, animators and developers and there are very few of them that have much of a passion for messing around with the hardware and would far prefer to just upgrade every few years (we also don't really have much of an IT infrastructure). We buy Mac's and replace them when they are no longer working optimally for our team. That said, we've had some iMacs last 4-6 years with no complaints from their operators. I will caveat that and say that I did go through and replace all the HDD with SSD's on the oldest round of iMac's before you could get the Fusion or SSD upon order for a reasonable price.
