Reading these comments tells me that the state of embedded programming is as strong and as fragmented as current web development.

My company uses VxWorks, MQX, Android, Windows CE and Linux. We're dropping VxWorks because it's costly and cumbersome. MQX is being replaced by whatever Freescale/NXP is pushing now, we put a lot of resources into the older version of MQX and aren't following them into their new incarnation. We use Android for special devices, but it seems to take a good amount of work to put it on custom hardware.

The OS that makes the most sense for embedded work nine times out of ten is Linux. It's widely used, documented enough, and has the most vendor support.

A good setup? You can get an AM335x EVM with an LCD, which is the same processor as a Rasberry Pi. I believe i.MX6 has an EVM with an LCD as well. Bottom line, you should talk to vendors, to see what they have to offer. Since it sounds like you have limited experience in this area, working with a vendor that will give you support is probably the most important thing.

Your developer tools are entirely dependent on your OS and chip. Ultimately, doing embedded work you're most likely going to use C/C++, but if you're on Linux or any modern operating system, then you have the ability to use a scripting language.
My GF swears by it. And I fully support her decision to use it. I'd use it if I was born with the bit and had the need.

Probably less of an option in rural India though as a sibling comment pointed out.

Hi, Author of the paper here. After seeing the email Spender sent me, I can say most of his fixes/recommendations don't change a lot of the core messages/points/etc, even on grsec related sections. I'll be releasing a new version soon-ish merging in some of his feedback.

I tried extremely hard to not be "partisan", and I don't think I am kind to any container platform, but it's hard to argue where Docker is vs Rkt in terms of security (apart from possibly hw virtualization in Rkt Stage 1). I agree some of the Rkt stuff is higher level, mostly because after a large number of container assessments at some major companies, I have yet to come across Rkt. Most of my research comes from my own brief analysis, and the analysis of some peers. Maybe a future version will cover it more in-depth.
It can be a good business decision to run a business for maximum profit and a quick exit. However when you do that with a major corporation like Intel, it tends to make people unhappy.

Intel will continue with the high profit margin right until the chips don't sell. And then Intel gets to go out of business.

Even in male dominated fields this applies.

There are pink hammers, pink calculators, and plenty of other pink tools that would otherwise not be gendered. A black handled hammer isn't masculine, it's gender neutral, it's functional.

I didn't read through all the papers, but didn't the testing labs measure the weight of the apparatus precisely before and after? If it's any mass being vented off, I assume this would show up, and you can make precise predictions about how much mass would be needed by calculating upper limits for the velocities these particles could be accelerated to.

So your counter argument should be pretty easy to test, and I'd be surprised if this isn't accounted for in these experiments.

In the example of FTL neutrinos there was only one non repeatable instance - here we have at least three.

Most of the times skepticism is good, but sometimes it can blind you - at the very least this effect needs to be investigated further because the implications - if it turns out correct - to both practical applications and physical theory - could be huge.
Unruh radiation itself is well established theoretically, though it has not been observed experimentally.

However, the theory behind Unruh radiation says one thing that creates an obvious problem for anyone trying to use it to explain something like the EmDrive or the flyby anomaly: Unruh radiation is felt by objects that are undergoing proper acceleration. That is, they have to already be experiencing thrust. And according to the theory, the thrust they are experiencing has to be very, very small, so that the wavelength of the Unruh radiation is of the same order as the size of the observable universe.

In the case of the flyby anomaly, the spacecraft passing by the Earth were in free-fall orbits--i.e., zero thrust. That means zero Unruh radiation.

In the case of the EmDrive, technically the apparatus was feeling "thrust", in the sense that it was sitting on the surface of the Earth and therefore feeling weight. (Weight counts as "thrust" in this connection.) But the weight of the EmDrive apparatus is many orders of magnitude larger than the small accelerations that would be required for the Unruh radiation explanation to work--the wavelength of Unruh radiation associated with a 1 g acceleration is about one light-year, much, much smaller than the radius of the observable universe.

So, bottom line, whether or not the EmDrive results themselves are valid (I am skeptical, but the whole thing is still being hashed out so it's too early to know for sure), it doesn't look to me like Unruh radiation can account for results of this sort.

(Btw, as gaur pointed out, Unruh radiation actually is a result of quantum field theory in flat spacetime, i.e., not GR, as the article claimed.)
Noted, I will update my post with that in mind.
It really was pointless anyway, nobody should care what I think of the original piece. I just get annoyed when I read something like this; I would rather just read the statements, but people want to make you think it proves their point.

Author of the paper here. Thanks. As for Jails and Illumos, I would be willing to bet it's people not looking, but I haven't looked, so I can't really say. I agree it's kind of a mess, but it's getting better!

There is a phenomenon where individuals with hydrocephalus, a condition where the brain cavity is filled with fluid, can still exhibit normal intelligence. I suppose the two broad explanations are that brain matter is either denser in these individuals, or that a brain can still compute well with less brain matter at least in some cases (possibly by sacrificing on some other not-easily-measured mental faculties)

Perhaps "trustworthiness" is not the best word for the concept. I'm not sure mechanical hardware is more trustworthy (mechanical stuff also fail often and can be unreliable), but their behavior is somewhat more malleable by the user (i.e. via extra force), as opposed to complex blackbox electronics/software.

I think we need a good term to describe this specific kind of trustworthiness.
That's scary, especially considering the controversy over a similar problem that also lead to unexpected shutoffs: https://en.wikipedia.org/wiki/General_Motors_ignition_switch...

> ... (McCulloch) proposes a constant term that modifies the acceleration corresponding to the inertial mass. He says torsion balance experiments can't detect it because torsion balance experiments measure differences in acceleration. But he's wrong because since it's a constant term he "predicts", it should manifest in the Eotvos parameter. Torsion balance experiments have gone well beyond the limit to detect this. But it's irrelevant because he completely misunderstands all the theory he bases this on.

In fact, after trying numerous approaches and trying to work through the car’s software controls, Deeter found himself driving to a board meeting with one hand on the steering wheel and one holding shut the driver-side door. “It wasn’t terribly smart, but I didn’t have time to call an Uber.”

Ask HN: EE going SWE, how do I get noticed?
This is a followup from my last question here:
https://news.ycombinator.com/item?id=9947816

I am now an entry level SWE, and have interviewed in person many places, including Google in-person. I interviewed around ~10 places via references and my school's career fair, but all ended up not working out despite going quite far in some of the interviews.

My question pertains to the fact that now I find it hard to get companies to even look at my resume, since I don't have any direct SWE experience, despite my knowledge. My project work is a bit lackluster since I studied algos and data structures primarily to be able to do well on interviews, and most places won't give me the time of day without a referral currently.

I have made a site, found here www.hectorramosjr.com (Let me know if I shouldn't post it here) and tried doing some quick projects, but to no real avail. What am I doing wrong? I would thoroughly appreciate any advice, as I currently can't get any further interviews, and I find it a bit depressing considering how well I've done on some interviews to not even be given the time of day by other companies.

Hi, author of paper here. Couple things:
- I agree the requirement of using Docker hub or their private hub is an unfortunate requirement, but I'm talking purely about the technical implementation. "Does not work for enterprises at all", well, there are a number of large enterprises that would disagree with you ;)

- For the table w/ SELinux row, Rkt is optional "scary" yellow because it only supports a single MAC implementation, it isn't very portable, and it's not enabled by default, vs LXC and Docker which both have quite strong MAC policies by default. Trying to parse all the info down into a table was honestly quite difficult (balancing being able to read it without a million footnotes for each point). Hopefully readers don't take all their take-aways from the table, and read the paper in full.

- I used Rkt for the name and rkt for the command. Seemed to help consistency.

Thanks for your feedback.
Amazon has front loaded cash signing bonuses.

What you call "signing bonus" I call "guaranteed raise if you stay"
I don't disagree, but it is worth remembering that purely hardware systems aren't foolproof either. I had a fuel pump fail on my old car (would be 15+ years old if I still had it), and it took out the brakes and steering at the same time (virtually standing on the brakes to slow down at all, and I ended up running the car off the road as I couldn't physically brake or turn the wheel enough to stay on the road).
Honestly, I wouldn't classify 8 forum posts as a "known software problem".

I think if this was as wide spread as you make it seem, there would have already been a recall made by VW as this is clearly a huge safety hazard.
That's deeply not true for at least 10 years. Amazon has worldwide coverage for oncall rotations, and VPN for access from home or anywhere with a cell connection
Cool idea but be careful about publicly admitting to using consumer licensed music (Spotify) in a business setting.

Because your company is playing music for your staff it is considered "Public Performance" and therefore falls under a different royalty rate.

"NYC hasn't produced a blockbuster startup, nor is there one in the pipeline."

Digital Ocean, Foursquare, Tumblr, Gilt Group, Genius(nee Rap Genius), SquareSpace, Etsy, Mongodb, WeWork, Kickstarter? I would say those are all pretty high profile successful startups.

Oh but they aren't worth > $50 billion dollars in funny money so they don't count? Nice arbitrary number too by the way.

Also Canary.is computers vision/alarm system - doing really well on Amazon and also available in the Apple store - a real physical product made in NYC.

Cockroachdb, InfluxDb, are also doing interesting things in datastores.

As for the established players, Google's second largest campus behind Mountain View is in NYC, as is Spotify, Twitter, DropBox, Soundcloud and Facebook.

Cornell University Tech is partnering with Google to open a campus on Roosevelt Island.

There is no hype in NYC tech just a lot of people getting on with the business of work.

You are either willfully ignorant or just a real dope.
My username gives away my bias however, I think you will find Jails and the work Joyent/Illumos have done with containers, to be actually engineered secure from the getgo. Linux, well, I think it's obvious the route Linux took. And none of their "container" solutions were ever designed with security as the starting point. It was always bolted on as an after thought.

Trust me people have been looking for kernel bugs in FreeBSD to exploit jails since it was created. The record their speaks for itself. It's not a lack of eyeballs.
Really ridiculous connection. SpaceX has spent years working on redundant safety systems for Dragon, testing them, refining them. That's a large part of why it's taking so long.

And if you haven't forgotten, Tesla reigns over all other manufacturers for safety ratings. Trying to imply their cars are aesthetic and not functional exhibits a level of ignorance on the topic that renders your contributions essentially meaningless.

And, lastly, are you inferring this from the fact that Musk spent 5 minutes explaining that the interior was actually pleasant and modern and well-designed? From that, you jumped to the conclusion that most functionality at SpaceX was taking a backseat to the interior design? I'm sorry, have you noticed what they've accomplished? Do they seem to be slacking on core functionality to you?
It's more than two: in between TechCrunch and WSJ there are four... which isn't much better.

Except there's also a statement from Tesla: "we believe the issues with falcon wing doors are largely behind us".

That sounds like a known issue.

Not to mention Tesla offered a loaner vehicle while these issues were being repaired...

"Yeah, your $140,000 vehicle is in the shop due to manufacturer issues. Here's a Chrysler minivan from us while we fix it." I don't know - that to me would be more than a little insulting.

The Tesla is not a supercar. It's a luxury car. Its competitors are BMW/Mercedes-type luxury cars. Just because a car is $150k does not make it a supercar.
Thanks for responding. I'm talking about the technical implementation, too. How is a feature hidden behind an environment variable a "strong default?"

And Docker simply screenshot the table, so noble goal, but...

I suppose I could remark upon MESOS, Rkt, and so on, and how getting names right is important because it characterizes the rest of your thoughts and analysis of the things you're studying, but I'll stick with the question I started with here.

> If anything Google needs more different minorities if anything, for instance Latinos and Blacks.

This is a much bigger problem than just the software industry in the US. I'm a Navy veteran, as a nuclear reactor plant mechanic. I remember being shocked in MEPS (the enlistment and entry processing center for all branches of the armed forces) by the number of black men enlisting in the Army and Marine infantry - it's much higher than the local population would suggest. But of the roughly thousand or so people I worked with as Nukes in the Navy, I can recall only one black man. The trend is just as strong in college. While I'm working as a software engineer today, my degree isn't in CS: its in Mechanical Engineering. The same trend applies there, too. I've worked with a grand total of one black engineer professionally, and he was an intern! There is a serious problem in this country with our failure to attract black and latino talent to engineering. Its pretty frustrating to see all the media attention focused on bringing women into CS, while almost zero attention is being focused on the lack of black and latino engineers.

I can't point to any single factor that is driving this trend. But it must happen in High School or earlier, since it's already totally broken by the time folks are graduating HS.
Just for the record I'd never do an embedded gui in html. Well maybe not never, but not until it's common. Sounds like a nightmare of layers and compatibility issues. If you run into a problem, where do you even start to look?

I've been doing straight opengl-es on my devices and like not being locked into a gui platform. It makes even more sense to do it this way when you've got external buttons as inputs, because you're not even able to use slots and signals, which is the most useful part of qt.
It looks like people worked hard to get offended by this. It's not even "blackface"...it just overlays Bob Marley's face on top of your face. It's similar to all the other dumb face filters that snapchat has, and was done with the permission of the Bob Marley estate.
It's a small thing, but between this and the properties syntax sugar (avoiding having to hand-write all the SetX GetX methods that litter Java code), it adds up for cruddy stuff where you end up needing to define a bunch of POCOs, for instance with EF or JSON REST APIs.

Ugh, in 2005 AMD X2's were wiping the floor with any desktop processor Intel had. The only reason Intel stayed in business was that being much, much bigger company than AMD, so they could 1) outsell AMD on availability basis and 2) ditch NetBurst and come up with newer architecture (which was a glorified version of their mobile/older architecture).
Japan is 72nd, and their biggest beef is "記者クラブ" (Journalist Club) were established domestic media gets precedence in press conferences.

It partly looks like political maneuvering to get more question time in them. I wonder how other countries do it. I heard there are "first question rights" and "first rows" in the US also, so old hands like Helen Thomas had advantage.
Who cares about $40MM dollars any more.
I can guarantee you that in one year neither you nor your friends who are working on it will think it was "once in a lifetime" idea--not because it's a trivial idea, but simply because there's so much opportunity out there and people who can come up with a good idea can and will come up with another good idea. Also, Anchor is hardly a success, it's just an illusion because they're getting lots of PR. PR does not mean it will be a success.

The root issue is clearly NPM's terrible performance, but it seems to have been exacerbated here by VirtualBox's terrible networking.

This is exactly the overreach I am talking about, inserting social issues into subjects that are not about them or have at the best mild correlation.
No it isn't. Physical distance change line capacitance and limits clock rates (or requires higher voltages, same thing). DRAM latency has always been completely dominated by precharge time inside the array; the whole idea of synchronous DRAM was to take advantage of that to stream data across many clock cycles (that is, get a very "wide" interface to that can transfer a whole cache line at once on a few dozen wires) as it's happening.
Agreed. Call an Uber anyway; no board meeting is worth risking your life, or someone else's for that matter.
Why? It seems true for some of the decent definitions of "material standard of living" although certainly not all. What they really lack (relatively) is social power, kinship tie quality, and many other more important things than internet access, smart phones, and technology (all of which may correlate with depression.
