The networking field, as with the server hardware field, is seeing a movement towards commodity hardware. Custom network silicon is expensive to develop, and no longer is returning the investment that it did. This is cause companies like Juniper and Cisco to look at ways to expand their profits, while essentially making nothing on the hardware.

Cisco along with others are looking by at things like licensing the IOS to run on any device. So a company could buy 50 white box switches and slap IOS or JUNOS on them.

In the networking world OSs are even more religious then the Microsoft Linux debates of the past. I know networking shops that will never buy anything but Cisco because they only know how to network on Cisco and they refuse to learn anything else. That is the market that Cisco is going to target.

The software will run on inexpensive dumb hardware from whitelabel manufacturers such as Quanta computers. The secret sauce in hardware that gave Cisco big margins is increasingly replaced by software that is good enough (e.g. You can use SDN controller and a cheap switch hardware to replace very expensive Cisco stuff). The trend in Enterprises and telcos is to use cloud (AWS, GCE, Azure,...) and open source (aka Facebook Open Compute) so the hardware spending has slowed down. (in tier 1 carrier I deal with, all new deployments must be on Openstack that uses whitelabel hardware purchased in bulk). EMC, Oracle, Cisco, HP are facing the impacts of such decisions.

> an antithesis to its origins, where an email went straight to the machine of the final recipient, from the machine of the original sender —with no intermediates besides the DNS servers.

Wow, is that some historical revisionism. Emails used to look like thrash!cmu!ucb!vax!tedu which meant send it to thrash, who will send it to cmu, who will send it to ucb, who will send it to the vax, which will deliver it to tedu. If you had a direct line, you could skip a few hops, but very few people were talking directly to the machine of the final recipient.
I think you're conflating cargo culting with pragmatism though. The generalized reason that everything is messy is because it's too much work to gather all the knowledge and consider all the angles and do a big reset, and even when you do, you run into unforeseen issues that may end up being just as bad (see Gall's Law).

Consider a pet peeve of mine: The Turkish Problem. Specifically, when Turkish was latinized almost a century ago, they had the brilliant idea to use lowercase i and capital I as separate letters, and then introduce their counterparts İ and ı as new letters. This now means you can't upcase or downcase the letter i/I unless you know the language. Note that it took 11 years for Firefox to handle this correctly (https://bugzilla.mozilla.org/show_bug.cgi?id=231162), and even then you have fractal complexity if you're dealing with an internationalized site. I had the pleasure of working on a film site that was localized to Turkish, where I realized that it is not enough to know the language of the document, you must indeed know the language of every string in the site. In the case of film titles for instance, many films in Turkey are known by their English title, and in that case you must use normal capitalization rules, so now every film title has to have the original language flagged. This is not a small issue because if you are a Turkish speaker it just looks wrong if you don't get it right.

Why do I go into this digression? Because from a programmers perspective, this is insane. In retrospect it would have been infinitely better just to invent a new letter or use an accent or something that fit the alphabetical semantics of other latin languages. But they didn't. This decision went into effect in 1929 when the concept of character encodings was something only maybe a handful of engineers and mathematicians had even considered, and the concept of Unicode would have been beyond science fiction; it probably seemed a perfectly reasonable hack at the time. If we were to reverse it now in order to ease technical concerns think about all the fallout with all the existing documents and printed materials. It's just too big a price to pay. The world is full of these things, there's just not a big enough ROI to justify overhauling these old systems.

That's very different from the more actionable problem of people who go through the motions without ever questioning how they do things.

"the moon mission was happy with vacuum tubes on the ground and the transistors of the day"

That is not actually the case. The Apollo Guidance Computer was one of the first (possibly the first) computers to use integrated circuits (RTL).

One of my professors in undergrad worked on it. They built the whole thing out of NOR gates, figuring that it would be better to have one component and test the crap out of it than have several different components. It's possible to think up arguments either way, but in any case, it worked. :-)

Of course, as long as you have either NAND or NOR (or either AND or OR and an inverter), it's possible to build any Boolean logic function.

Does Time.now + 1.day return the time 24 hours into the future or does it return the same time (hour:minutes) but the next date? (it may be more or less than 24 hours from now if the UTC offset has changed for any reason e.g., due a DST transition). How do you express these different cases in Ruby explicitly?

These companies have nothing to do with the businesses that make Cisco its real money.

Growth in compute is from the cloud companies. They can purchase switches from ODMs like Edge-Core, Quanta, and Celestica directly. At the end of the day, because switching has largely converged on the same merchant silicon (Broadcom Trident/Tomahawk now, perhaps Barefoot Tofino in the future), they end up with a similar product at a lower price point. Either these companies are big enough that they have their own switch operating systems or they license one.

It's simply a different world than a few years ago.

Wait, so your logic is "Time travel is impossible and so anything that implies it is impossible"?

Where do you get the idea that time travel is crazy? Wormholes and the implications come from solid math (from what I understand).

Given that, GR and wormholes seem more similar than not.
Yes, that's exactly right. Ductility is measured by how far a metal deforms before breaking entirely. Ultimate strength is measured in terms of how much pressure can be applied per unit of cross sectional area. A metal that can be elongated 50% while under 1000 MPa stress absorbs lots of energy. If a metal is less ductile, it will break after little deformation and therefore stop absorbing energy.

Note that the metals under discussion here have very high strength (~1000-2000 MPa) and relatively little ductility (~10%), but are more ductile than other materials with this strength. On the other hand there are very ductile alloys that can tolerate 50% elongation and have strengths around 1000 MPa. These are achieved by adding basically a shitload (20% or more by mass) of manganese.

This is different because $GOPATH is a requirement of the language and in _other_ languages, you have to manually clone the repos in the correct root folder which you store all your code into.

Go allows you to do a go get reponame and it'll do the git clone stuff for you.

that is nothing short of amazing as far as code management is concerned. I love it.
buried under a thousand windows and widgets, or theres not enough RAM left for it.
On another note, I suggest you work around this limitation, you can write a benchmark in Go in the $GOPATH of your company or anything and then use `go install` to install it to the $PATH of your machine, so you can call the benchmark directly. This will separate the codebases.

Otherwise you can write the other language code in the $GOPATH itself.
Mehh, I’m glad this got dupe’d. This first time I read the article I found it interesting & the subject extremely valid.

That said, the article would be better if it alluded to real examples. The fictional ones are funny & they did get me to investigate … but I can where some creators or maintainers would be pissed at the notion they did include some of the cruft reported. There should be some mention of this or a link to each scrutized project’s repo.
This tutorial is much more basic and has much less practical statistical applications than the R tutorial posted last week (https://news.ycombinator.com/item?id=12264360), which itself is out-of-date relative to the R for Data Science book (http://r4ds.had.co.nz/)

I really am curious why anything "R" and "Tutorial" gets massively upvoted to the Top 3 of HN like clockwork nowadays. I might have to restart my R tutorial screencasts since there appears to be a demand. :P
There's a number of high-strength steels like this. Bisalloy [1] are an Australian group that produce Bisplate and SSAB [2] are a Swedish company that make similar products under the Weldox/Strenex/Hardox brands. As you mention, Nippon Steel also make a range of them.

That said, neither is quite like this flash bainite. Both are very hard steels, so manufacturing and fabrication techniques need to suit the steels at hand. For example, machining the steels I listed can be very difficult and murders tooling bits compared to machining mild steel. Welding can also be difficult and usually involves significant preheating and post-weld heat treatment processes. Flash bainite apparently has some benefits in those areas but to what extent is hard to quantify.

I'd love to know more about this flash bainite process, but their website is really scant on details. Other sources of info suggest that you weld the structure together then flash process it afterwards, which I'd assume is completely useless for anything with complex geometry or substantial size. A military report [3] of its performance shows that welding after FB treating literally halves its strength, as you'd expect since the heat of welding is basically like traditionally heat-treating it over longer durations. In that sense the ones I mentioned are better because you can more slowly heat treat them post-welding via more flexible methods that can deal with more complex shapes. This lets you get restored strength properties because those steels aren't reliant on a flash-style process.

Where I think this reigns is in its ability to be formed easily whilst still being strong. Forming those steels I mentioned is a nightmare. In that sense it would certainly have applications where you can fabricate via fastening (rivets, bolts, etc.) but it seems to fall short when you need to weld it into anything more than a small butt-weld of two sheets.

Certainly an interesting development and I'd love to see it realised to a commercial product as it'd definitely have some uses, but it's not the be-all-end-all holy grail of steel.

I've used it a few times. It's a cute way to make shallow DSLs which need to identify binders. It gets very annoying to do any work under the binders however making it scale poorly to many tasks important in more complex DSL implementations.
> One popular suggestion is that any causality-violating wormholes would cause a feedback loop of virtual particles to accumulate inside the wormhole and destroy it.

I would imagine a more likely solution is, wormholes either can't exist or can't transmit information.

> The best physical theory we currently have admits the existence of wormholes.

Just because the maths says it can exist in one set of equations, doesn't mean it can/does exist in our universe, especially lacking any evidence.

I'm not saying to stop researching the idea, but anyone sensible knows the outcome.

They will not be possible not matter how much you want them to be true. Just because something can exist doesn't mean it's either likely or not crazy.
I would guess that that would depend on the situation.

I would think that whatever method you have of moving a mouth of the wormhole, would have some interactions with the masses providing the gravitation.

Also, I'm not 100% sure that a wormhole would not have something like an inherent mass, because iirc there are solutions where a black hole mass is entirely because of the way spacetime is set up, without any particles needed? I'm not sure about that, but I think that is what I read..
It's scary seeing all of these lay-offs happening. I'd hate to be looking for a software engineering job right now.
Harvard is a notoriously easy school - once you get in classes are relatively easy. Grade inflation is rampant.

It's not clear in this case that what they've built is mathematically analogous to GR wormholes. This seems more on the "it's kinda conceptually similar" rather than "this works exactly the same as a wormhole under the proper translation of variables"

Who are the core that drive this massive, amazing ecosyssytem (yeah, please what's another word for ecosystem? Am I the only one tired of it to describe any system?). Here are some thoughts.

1. There are the leaders of the movement who often don't work full time it's for themselves or an employer that pays them to be them. A few examples of this group (I'm including both "free" and "open") would include Richard Stallman, Linus Torvalds, Bruce Perens, Eric S. Raymond, Tim O'Reilly, Larry Wall, Guido van Rossum, John Gilmore. That's obviously not a complete list.

2. There are the outstanding professional developers with passion for their FOSS projects. They always seem to work for themselves or always manage to find employers who encourage open source contributions.

3. There are developers who are learning or otherwise haven't yet started working full time.

4. The 1% (mentioned by several commenters) who have very busy lives but manage to contribute as much as they're able.

I may be off and I'm definitely over simplifying but I say thank god for all four groups and others. I feel gratitude every day.

Yes, the FOSS world is political and narrow at times, which is a shame but that's human beings anywhere you find them.
