I'll never forget my banking and financial markets class while getting an economics undergrad degree. The teacher said something close to "I know when you're reading the Wall Street Journal, it seems like just about everything we're teaching now doesn't work, but I promise it's real. The world is just weird right now."

This was during the early days of Quantitative Easing, the Federal Reserve and many other nations (notably from the lesson I'm thinking of, Japan's National Bank) were flooding money into the market, so QE wasn't working properly.

There is a serious problem with economics on the larger scales, and I've yet to hear anyone talk about it.
The important part of the book isn't the swearing, it's the science and engineering. This isn't William S. Burroughs.
Having higher power density is very convenient, but not exploding is a great characteristic of NiMH batteries. Charging mishaps can happen with those as well, but I've never heard of a cascade failure overtaking NiMH while just sitting there.

I've had young programmers sneer at me about my continued use of NiMH AA and AAA batteries, but there are some advantages.
I believe that constant swearing is inappropriate. As a matter of fact, in that book it decreased believability for me. An educated astronaut, faced with a possible extinction, would want to leave a worthy testament/diary, and not an expletive-riddled notes.
As 'dpark noted, you can't delete a comment once it's been replied to: I believe this is to ensure that there aren't dangling comments. If the comment is still new enough (less than 2 hours old, I think), you may still edit the comment. For example, in this case you could chose to include your note about missing the word new in that comment itself.

Thanks. This can explain the situation where most people are struggling to replicate a neat result in a paper.
I think lateral stresses (from people's feet, etc) did mine in. The seams failed, and things quickly deteriorated after that. A lot of Ikea stuff is designed with zero redundancy or design margin, so if any part fails or weakens the whole structure is compromised.
> Marriage means legal changes. Being married means that someone can hold you accountable for your spouse's debts. Being married means the joint ownership of property. Being married means next of kin status. Being married means legal presumption of paternity. Being married means survivor's benefits when one spouse dies.

Why do we tie those to sexual relationship status, though? The only one of those for which that makes any sense is a legal presumption of paternity, which we don't need now that we have accurate genetic tests (save for identical twins).

Why shouldn't my brother, or my best friend, or members of my yacht club, be able to hold joint ownership, or be my next of kin, or get benefits through me?

Secular marriage is just the husk of religious marriage, sapped of what actually makes a marriage marriage.
Any confirmatory lab would have to be licensed in order to get grant money for it. Just like CPAs who do an audit. Sure there is some corruption and drift toward hiring more lenient firms, but it basically works.

Side note: it is weird to me that everyone talks about whether researchers can afford to pay for confirmation, but researchers never pay for anything, grants pay for everything. The granting institutions might even be excited to try a confirmation process.

They're not arguing that government should get out of the marriage business. I've seen that sentiment before and it's totally consistent. I might even agree with it. But these people here are arguing stridently for government-endorsed traditional marriage, and against same-sex marriage, all while having that tagline at the bottom of every page.

Those things already have very little space tolerance because the most important feature of any 'premium' laptop is that is as thin as absolutely possible and it is thinner than the previous model. All else is secondary. This would mean an even further thinning of the battery itself.
I work on Mender, so I can tell you how automated rollback works there.

The update is written to the inactive rootfs partition, uboot is configured to boot from it and the device is rebooted. Using the bootcount feature of uboot it is possible to roll back automatically if booting fails. Once the mender daemon comes up it will try to report the success of the deployment to the server. If this fails it will also roll back. Only after successfully reporting the success to the server Mender will "commit" the update, meaning configuring uboot to persistently boot from this updated partition.

Mender already does compression, but you are right that there are optimizations that can be made for application updates, e.g. delta or other types of updates. We are planning to implement this as well. The first priority for Mender is to make it robust, i.e. make sure the update is atomic and that you can always roll back.
But one of the interesting parts of the paradigm of hierarchically-threaded online discussion, is that only one subthread/reply to a given thread has to be a "productive conversation" (i.e. to continue the thread in the "obvious" way); the other subthreads can be tangents, and tangents do not "derail" in the same way they do in a flat-linear-threaded forum.
> Yet art is insanely expensive.

You'd be surprised how cheaply art students at your local college would be willing to recreate pieces for you. These people are already quite skilled by their 20s and it's no problem for them to make a copy of a piece. Their original pieces made for class can be found for next-to-nothing.

Second-hand shops are full of wonderful pieces for cheap.

Photographs and digital art are extremely cheap to print and frame. My local UPS store will do huge prints for a few bucks.

Mass produced art, like that from Ikea, is usually less than $40 a piece, a lot of it is less than $10. Homegoods and Hobby Lobby is another good place to shop for cheap mass-produced pieces.

You can do-it-yourself for the costs of materials. You don't need much skill to toss some colors onto a canvas.

Art can be cheap and it can be found everywhere. It doesn't need to be some hand-painted master piece. A printed picture or photograph in a frame will work just fine. Or a simple vase with some flowers.

Yeah I'm gonna need an explanation too. Even with hashes hardened against DOS attacks, the lower bits tend to vary with the input far faster than the upper bits.

For instance, several popular hash algorithms (of the form 31 * hash + value) will have the same upper bits for any two strings of the same length, up to about 12 characters in length when the seed value finally gets pushed out. Unless you're still using 32 bit hashes for some reason and then it's most strings under 6 characters long.

Multiply by prime and then add or xor the next value guarantees that the bottom bits are less biased and so fits with any hashtable function that uses modular math, even if the modulus is taken by bit masking. Getting the upper bits to mix would take a different operator or larger operands.

I know I've encountered at least one hash function that uses a much larger prime (16 or more bits) as its multiplier, so it's not unheard of, but it's certainly not universal.

People put experimental digital blocks in ASICs all the time, it isn't necessarily that expensive. Its a bit like taking an extra pair of shoes on holiday - in general, I'm a bit concerned about reaching the airline's baggage weight limit. If you ask me to add your shoes to my bag before I start packing, I'm going to say no. If you ask at the end, and I've got some space left, then fine.

However, he's probably talking about an FPGA implementation. That'd be sufficient to prove the concept. Once you've gone that far, you can normally do some simulations to predict the energy consumption on a real chip.

>> People really need to be educated on battery chemistry when they buy battery operated products.

Or it should be illegal to sell products that can catch fire/explode. I admit to knowing nothing about battery tech but if there were suddenly massive penalties for exploding batteries I don't think it would be long until we had a workable solution. It should not be up to a consumer buying a phone/laptop to learn about how their battery works and how to identify a potentially dangerous situation.

It's unfortunate that this was the experience you had. I imagine whomever you talked to was under the impression that hardware can't be taken that isn't accepted as part of a Genius Bar appointment, and didn't know the severity of what could happen would the battery fail. A training failure on Apple's part. That said, my cousin took a similar era MacBook to the Apple Store for swelling, and was able to see a Genius that afternoon and got a battery swap.
In this case he happened to handle it pretty well. Educating people that this CAN happen will allow them to handle it when it does happen. Most people probably would not handle it this well.

Actually, the touch pad tends to pop up when the batteries start swelling. It may not have in this case, but it's common enough that people get _some_ warning.
To be honest, I was actually distracted by the the swearing because it really was unnecessary writing. Like there are places where as an editor I would have told him to cut it too. --E.g., when he finds out what re-runs his crew member has and immediately follows the sentence with some cursing. It just would have been better with a lot of other literary devices.

Although some books will lose something if you subtract the harsher language, this is not one of them.
Most of the H1B folks who are here for 3yrs don't live out of the bag for 3 yrs. If this attitude remains, the smart folks will avoid US entirely.

This would make most Americans really happy. We don't want H-1Bs.
So that makes it OK to use expletives in an educational setting? Sounds pretty unprofessional to me. Now, they may have overdone it in this case, but in general, I think that expletives should remain outside of professional settings (classroom/workplace/lecture hall/etc.).
All popular devices will have a few that have this happen of the lifetime of the device. The Note 7 and hoverboards were exploding at a rate far higher than should be expected -- that was the news. For example, there was a video of an Inspiron exploding a few weeks ago that new made its way to HN (that I saw).

That does not sound like a coincidence.

Did the constant change when the universe was smaller? Or does the light speed depend on the size of the universe?

True, but it's also standard for HN users to flag rhetorical advocacy pieces, especially ones with sensational titles.

My gut feeling is that more users are flagging this one because they think it's off-topic for HN than because they disagree with it, but that's just a guess.

Kids need models of appropriate behavior. They don't need models of inappropriate behavior -- they've already got it.
My fiancee's older Macbook Pro (non-unibody) had a battery swelling issue. The bottom cover of the computer popped off in the middle of the night from the swelling. We went to the Apple store, and were told "you charged this battery too many times, we will replace it for $99." The computer was about 5 years old at the time.
Sorry! I'm not trying to, but I'm also not sure how else to interpret them. As I said, I'm willing to believe that papers occasionally slip through the cracks (the arsenic life thing from 2011 could have been caught in review, for example), but the idea that a decent number of papers papers just slide through the peer review process is totally unlike the experience I've had with my own and my friends' and colleagues' papers.
Yeah this wouldn't be allowed in UK schools because of the swearing. "Crap" would be allowed, and "shit" might be in the context of a piece of literature being reviewed in an English class, but in a science class there's no need for it and it is considered inappropriate for children. For context, saying 'the f-word' or equivalent in earshot of a teacher would usually result in punishment.
This is done, to mainly deter people planning to jump visas. People show fake experience to get a visa. We have a mini industry in India supporting such jumpers. Though the numbers have reduced.

Hello HN! This is a ridiculously long but thorough guide to building your own hardware on a budget. Turn Touch is a small wood remote that controls your smart home.

I built it because I wanted it to exist and I was tired of waiting for somebody else to build it. And because I believe so heavily in open source, I wrote up detailed instructions on how to build each phase of the process: the PCB, CAD, wood machining, and laser cutting.

Turn Touch is also on Kickstarter, which is the culmination of 3 years of learning and work. I'm a solo indie developer and if I can learn to build this, so can anybody else.

Do you think asking a question sarcastically was the best way for you to add value to the discussion?
Mender should be pretty immune to power failures in the middle of the updates -- even if second partition is only half-written , it is still not activated.

OSTree seems to rely on underlying filesystem to provide protection from power failures. This is, in my experience, is not a very reliable mechanism, especially when the SD cards are used. Thus, it is likely that if you have a device using OSTree updater and someone yanks the power cord at the bad time, your device may become unbootable.

> Historically marriage has always been a religious ceremony.

For most of history it's been both a religious and a civic institution (marriage is an institution, a wedding is a ceremony commemorating, or effecting depending on the model, the entrance into that institution), both in nature and effect, with the civilian/legal effect regarding property rights and inheritance arguably most often the predominant aspect; the idea that the religious and the civic domains are fundamentally separate rather than deeply linked is a relatively modern innovation, along with which came completely separate religious and civic institutions of marriage in the places where that separation between the religious and the civic domains has been given effect.

The fundamental law of road congestion [0] states that you can't build your way out of a traffic jam.

This is because adding a new mile of road creates new supply X while simultaneously inducing demand Y, where Y > X in almost all transit markets where anyone wants to live. In e.g. the Seattle area, Y >> X.

As the name suggests, this is the most salient fact about highway construction. Yet it is widely ignored in urban planning circles.

It would be interesting to find out whether Apple's safety mechanism is part of the OS or the firmware.

The firmware on my PC will detect that it is running too hot, and halt. Presumably it will halt to catch fire since it seems as though the only thermal management at that point are the fans, but that is another story.
Okay. Your consciousness doesn't exist. Plz go away you scary philosophical zombie!
Of course that estimates are useful. But when you use proxy data such as cars to infer demographic data and present these as the result of a census, you can see why it's problematic. You're basically using the number of pick up trucks to estimate the degree of education in the neighborhood, then you use that same number of pick up trucks to evaluate the wealthiness of that neighborhood, and then you draw a conclusion on the correlation between wealth and education, which is the very input that's hidden in your AI model.

You may use census data to train a neural net to draw some conclusions, not to produce brand new census data.
That's ridiculous. My 2015 MacBook gets warm/hot as a matter of course during the normal use of software. How am I supposed to know whether it is a precursor to an explosion or just normal usage?

Apparently there is no way to know, and it is a matter of luck whether your <insert lithium charged device here> explodes.

As a society why are we selling these things (not just apple) that can explode during normal usage. If a car manufacturer had an equivalent such design, the manufacturer would recall and fix said problem for free.

And yes, if there is no "fix" then they should not sell this technology at all. I suspect that the tech-industry lobbyists would not agree.
I think "amateurish" is overly harsh here. He sets out a very professionial plan of measuring and testing. It is a nice post.

Yes, probably true that requiring a non-broken hash function is strictly better than his preferred prime modulus workaround. Okay, so? If you notice, the whole post keeps comparing a power-of-two version of his hashtable as well. Other than the one graph showing pathological behaviour of dense_hash with in-order inputs, everything in the post applies assuming a reasonable hash function.
