"is dealing with tight performance concerns found in realtime and embedded applications"

I thought tools like Astree and SPARK have knocked this out the park. Copilot was also pretty good on runtime side given it works in embedded. Just gotta structure your program to use the tools. I think they should cover plenty of use-cases given stuff like IRONSIDES DNS runs in SPARK.

"For general-purpose applications, of course, compiler transformation with runtime fallbacks is perfectly acceptable."

Also true for many embedded apps given the remaining runtime hit can range from single-digits to 40% depending on scheme used. Even more combined with something like SPARK or Astree for stronger, static analysis than the minimal stuff academics usually use. Certainly a subset will benefit from or even need methods you prefer but many won't. It's just management or a consumer's preference to save a few bucks shooting them in the foot. ;)

Do shoot me an email, though, in case I get some free time to run some ideas by you. I don't know enough formal methodists these days. My mile-high perspective can only let me do so much as a generalist. Gotta have specialists to help me filter the chaff from the wheat. Then pass such recommendations onto more specialists as always. :)
The 747 is one of mankind's crowning achievements. It's not only a technical marvel but an aesthetic one -- it looks truly beautiful while an A380 looks like it just got punched in the stomach. Along with the massive network of airports, air traffic controllers, mechanics, regulators, pilots, engineers, forensic analysts, financiers, etc... I think that commercial air travel is a more impressive achievement than the moon landing and the 747 its glorious peak moment.
I think your naivete is as beautiful as the freshest spring rose.

I wonder what this move has to do with what phone manufacturers are doing in general: hiding away components like the battery that were once open to the consumer, making it difficult to do anything but buy a new phone if the battery alone dies out. One can't get more anti-modular than that, and the Nexus 5X has the same deal: https://www.youtube.com/watch?v=VYFbSpvSE-w&feature=youtu.be...
It is 2016 and a lot of people are still not very good with computers, let alone mobile phone components. We live in Silicon Valley so it might be hard to understand this very simple fact. I invite everyone to go to an Apple store and just sit there and watch the scores of folks come in and have to be sat down and explained, slowly, about the simplest concepts for macOS or iOS. I have mad respect for Apple Geniuses.

Now, imagine a phone that has all these components and imagine the overhead of supporting that. Now you might say it is for tech people..that market is not big enough to warrant the R&D and support. Right call Google.
and the other bit about the harder, narrower road: you don't get to really find out how good the team is, and their plans that you let them run with, until a year or two or more later.

But I don't think there is any better solution. I agree that a bunch of documentation without substance is a waste of time, and just corporate smoke and mirrors.
You may appear safe but you never know... Services like Google and Facebook are pretty proactive about making sure unknown users can't access your account easily -- meaning that if someone from Thailand tried to access your account when you usually use it in the US from an unknown device, it'll generally not allow the login. But other services aren't as proactive and may be compromised, so it's definitely better to be safe. The best way is to use unique passwords for every service (or use OAuth with a service provider you trust), and a simple way to do that is with a password manager.

I personally recommend 1password, because they haven't had vulnerability issues like LastPass and don't store passwords in their cloud, but they store it in "your" cloud, e.g. iCloud, Dropbox, and it works very well on iPhone. But at the minimum just using a separate password for everything is the best way to mitigate these kinds of issues.
I still use my iMac, but I can't ignore the massive fan noise that the computer creates if I use it as a target display. I get that the computer inside is "free" but I'd gladly pay extra to have the components separated.
You are mistaking a few conductors for a well-designed peripheral. The surrounding mechanics and size matters a lot for mass-market peripherals... especially if the aim is to seamlessly integrate them (semi-permanently) into any phone. This means things like size, volume, nearby mechanical connections, robustness, and industrial design. With OTG, you'd be plugging and unplugging all the time (every time the devices goes into your pocket) -or- building "cases" one a phone-by-phone basis. That's not a standard peripheral... that's a hack with a dongle.

An Ara-esque expansion slot could've created a real standard.

E ticket, is a reference to how Disneyland used to price rides. The most exciting rides like Space Mountain, required an E ticket; this was before the pay-once-ride-anything plan was introduced.

You don't just sacrifice a few dollars to have a Smart TV inside... It has security vulnerabilities, features stop working, etc... Especially with the "stick" format of Roku etc., I just see no point.

Unfortunately it triggers any site that it doesn't explicitly know wasn't affected by heartbleed, which makes it trigger that vast majority of my passwords. This renders it more or less useless :(
Scant justification written here certainly. Your example of the child is not a good one in this context because the child can only do it based on knowledge or based on 'they look different.' Well turns out black people and white people 'look different' but these days we now know that we are all members of the same species.

The examples I am more worried about are not knowledge based (or judgement based). The ones I am worried about are the stories we tell about the _actions_ we take, why we choose A instead of B. Answering these requires us to introspect our own behavior and that is exceptionally difficult. Take for example a question like "how did you know it was safe to cross the street?" Many people will tell you that they 'looked both ways and saw nothing was coming' but if you have them wear earplugs they will get run over because it was really the fact that they were listening for the cars. Or say you meet someone and you decide you don't like them, you can't really go back an undo that, but it might actually have been the case that you didn't like the perfume they were wearing because it was the same one that your ex used to wear, and it had nothing to do with the person themselves. Virtually no one can catch all the cases like this because we are trapped by our own brains and our own blind spots. Buying your brain's bullshit without attempting some independent verification (eg by asking someone for another perspective or doing little experiments on yourself) is a exceptionally common, and difficult problem to overcome.
Ask HN: Generating reports on time series data without killing performance?
I have an application which contains approximately 10 million time series records growing at a rate of 1 million per year. This application generates reports on subsets of the time series data. These reports have poor performance characteristics because for each record in a time series, another subset of time series data must often be loaded as part of the computations behind the report. Effectively this can lead to N^2 performance. The current workaround is to implement these reports as stored procedures in the Oracle database where the time series data resides. This saves network roundtrips for every time series record.

I've found the stored procedures to be insufficiently flexible to handle complex requirements compared to modern programming languages (requirements come in for new reports on a regular basis). I'd like to generate these reports in application code (C#) but can't see a way around the performance issue. Has anyone dealt with similar challenges and how did you work around them?
This seems like such an odd move to me seeing as Google has made a much greater effort over the last year in marketing the Nexus line of phones. Sure, the Nexus line still isn't exactly a household name, but I'm sure it's more well known than the Pixel line.

I've had the pleasure of using my friend's Pixel C and 2015 Chromebook Pixel and was thoroughly impressed with both from an industrial design perspective. I personally find the Chromebook Pixel even better looking than the MacBook Pro I'm currently using. The Pixel design team really seems to know what they're doing, which makes me disappointed that this year's Nexus(now Pixel) phones look to be heavily derivative of HTC's hardware rather than having a more original design as employed by the rest of the Pixel line.

I can see why Google wants to make a Pixel phone, and after seeing the other Pixel products I want them to make one too, but it seems strange that they would choose to rename this year's upcoming phones when they are following the usual Nexus blueprint of being heavily based on a partner's design rather than purely Google's own. This is of course assuming the leaks I've seen regarding the new Nexus/Pixel phones prove to be accurate.

Yes, all true.

I suggest no such thing.

a good quote from him (and the article) "“You know things are going to happen,” he explained, “and sometimes it’s going to be severe. You still should be able to come home.”
This doesn't surprise me. I feel like the concept is nice, but they have to do a kick-ass job as making sure everything goes together well and can't just randomly fail -- I would hate if my phone's data got corrupted because a piece of it randomly fell off my phone or accidentally spilling some water on it, which would not affect a normal phone but may seep into between a pair of component edges. But beyond that, and more importantly, it has to make economic sense. Would it have been cheaper than a random cheap phone, especially in the developing world?
Nice, thank you. gonna take this for a spin tomorrow.
Great decision unifying PC-BSD under TrueOS.

The real innovation lies in SysAdm:

A new way to manage your Server, Desktop or Cloud-based system. By exposing an API via encrypted REST or WebSockets, it is now possible to remotely control all aspects of your machine, including management of software, updates, boot environments, users, backups, and more.

> When doing a job for a customer, use that time to resell other people's stuff with an increased price and don't tell the customer about you taking a cut. Sounds shady!

What is this in regard to? I was always a product builder (I haven't done client work in nearly a decade) and if I could utilize someone else's product inside mine to not only save me development time but provide a better experience and charge more, I will do that ever time. There is nothing dishonest about that.

When you get a cab from point a to point b, you are paying more than just the gas/depreciation, you are paying for the fact that someone is doing something for you. Same with every product.
Could you elaborate on your last line?
1. House - get a roommate (or 3) if you're young and have no family living with you. They will be your main friend(s)

2. Get a secured credit card from a credit union to build up your credit

3. Take out a loan with said credit union after a few months (even if you don't need it)

4. Friends --- work, meetup.com, gym classes, sports leagues,
random bars if you're an extrovert. Go everywhere you are invited.

5. Job - Use consulting firms here to get contracts and work your way in. Look for healthcare mainly,but a job in a decent sized city so you can connect with others (after an ok salary of course)

6. Phone - Get a cheap prepaid cell

The suburban ones you're thinking of are actually too low density for that solution to work.

A more Japanese approach (as mentioned several other times on HN within the last year and probably more before that), is roughly to zone by the 'nuisance impact' and also to plan local commutes along slopes of density (nuisance).

So you can have a mixed commercial / high density residential district around the transit hub, and a casually walkable (for fit adults/kids) commute from there to lower density housing.
I think this is likely a really bad idea for 'side projects' ... by acting as the middle man here you are taking on a huge amount more liability than you would be if you are using the (non-managed) Stripe connect model where the your customer has their own processing account.

Sure, there is money to be made here, but it isn't free and you need to manage the extra risk and liability that comes with it. What if someone discovers your platform hasn't got the same anti-fraud/verification processes that the larger players can afford by virtue of being a larger player, and decides to take advantage of it?

So much happened in aviation between the Wright Flyer's first flight in 1903 and the 747's in 1969. Since then, at least from a passenger experience viewpoint, relatively little has changed.

Is that because most new technologies eventually reach plateaus? Or have unique factors -- like environmental concerns about supersonic travel -- held back progress in aviation?

No. What the parent is saying is that: if the script was loaded from an external IP address, it should be blocked from talking to an internal IP address. The browser knows whether it loaded a script from an external IP address, and it knows what the internal IP addresses are, so it can just ban something loaded from elsewhere from talking to ports on your local machine.

Yet another drug banned for no good reason, basicallly because it could be "psychoactive". Doesn't need to be proven harmful. However the addictive, harmful, indeed deadly tobacco and alcohol are protected by government.
again, if manufacturers engage in the most basic 'mine is bigger than yours' playground games then it's not surprising that the users, who love shiny things, are not making a decision based on fact, if instead of releasing a new shape box every year, they really focused on a consistent product line then they could delivery incremental improvements and show users over time why their product is the better 'viewing experience' which is what it's all about really!
It was an interesting idea but I could never see it working myself. It looked like a solution in search of a problem.

So you're meant to buy a phone shell and separate components to plug into this, where you can upgrade different components over time? Ignoring technical issues, wouldn't the shell get out of date quickly as well as the components (with some components being incompatible with other shells and components)?

It doesn't sound cost effective considering how cheap phones are getting and how often we are seeing physical hardware changes still (e.g. fingerprint readers, screen size, thinnest).

Either way, I never finished my studies and didn't really regret it. It's easy enough to get a job as developer without a degree and eventually your completed projects become more important anyway for prospective employers.

These days I am a freelance mobile dev and I seem to be a little bit better than average at least, but by no means a genius. I can find employment very easy. Through freelance work I managed to make nice savings. These savings have allowed me to work full-time on my side projects for the last half year or so from Thailand. When money runs out, I'll be back in Holland as freelancer. Certainly I enjoy my life and I don't think I missed out by not having a degree, but YMMV.

I think if you keep your skills up to date, and finish some side projects, you'd have an easy time finding a job. With or without a degree.
