The big problem with using the raspberry pi in industrial applications is the single source and short production lifespan gauruntee (6 years [1]) making maintainance or long term production difficult. Industrial machines (e.g. printing presses) will easily last decades, and you often hear of problems finding suitable replacement electronics for them, so basing your control system on a single sourced component is a bit dangerous.

Other single board computers or system on module offer 10 year production lifetimes from introduction, e.g Variscite. This is possible as the manufacturer of the SoC (generally NXP or TI) also gauruntee to produce the silicon for 10 years, and as (unlike Broadcom) they will sell to anyone, alternative boards are available with the same processor should one board manufacturer go bust. They are a bit more expensive, but a trivial percent of the overall cost for an industrial application, and the difference isn't that much once you add a case, protection, industrial power supply etc.

I actually don't reject the theory that accounts of Gods appearing and speaking to people could be actual mental processes, guided by culture. I find this more believable than it is all fiction or lies (or that Gods have physical existence outside the human mind). But I do reject the bicameral hypothesis that we either have Gods speaking or we have consciousness, and that shift happened a particular point in time around the eight century.

Having worked with remote developers and freelancers both in employment and on side projects. Most important thing is making sure your requirements are clear, this will take time and might take a fair bit of trial and error. Just remember the requirements are crystal clear in your head but might not be obvious or straight forward to someone else.

Oct 2018: BBC web pages which have been removed from Google's search results
> To better explain how it works, here is a description by Steven Strogatz of what I'm assuming is a comparable device. Built in 1949, nearly a decade and a half after Lukyonov's, it's called the Phillips machine, after its inventor, Bill Phillips.

In the front right corner, in a structure that resembles a large cupboard with a transparent front, stands a Rube Goldberg collection of tubes, tanks, valves, pumps and sluices. You could think of it as a hydraulic computer. Water flows through a series of clear pipes, mimicking the way that money flows through the economy. It lets you see (literally) what would happen if you lower tax rates or increase the money supply or whatever; just open a valve here or pull a lever there and the machine sloshes away, showing in real time how the water levels rise and fall in various tanks representing the growth in personal savings, tax revenue, and so on.

“It’s a network of dynamic feedback loops,” Strogatz further writes. “In this sense the Phillips machine foreshadowed one of the most central challenges in science today: the quest to decipher and control the complex, interconnected systems that pervade our lives.”
Hey zawerf, your right. 2 notes.

1) it's very difficult to find nsfw images especially a particular kind like gore or suggestive nudity unless you Google things (which indicates a bigger problem). Maybe the solution is to use Bing (maybe this would cause the same issue in compariosn) or DuckDuckGo. But honestly I think if DuckDuckGo indexed a page, I'm pretty sure Google did as well. You would probably need something off of non indexed website which makes the job significantly harder.

2) even though google has all the images it's still not the best performing NSFW Detector Nanonets is.
3MB is not enough to store the kind of data you’re talking about. In your example you were coping files from an SSD to a removable device; what happens if that file is 4MB big? Or 20MB?

Some program executables are multiple megabytes in size these days, your CPU cache is much more valuable storing that than it is storing a random 20MB XLSX file you happened to copy half an hour earlier. ;)

> You do. You show wrong info in the worst case.

Yes, I’d repeatedly said that myself. However I was making a case study rather than giving a lecture on how your tool should be written. Remember when I said “there is no right or wrong answer”? (You have ignored my point that you cannot guarantee the kernels / fs drivers cache isn’t also stale though. That does happen in some rare edge cases).

My point is you shouldn’t be so certain that you’re method is the best because there are plenty of scenarios when accuracy and low memory usage is more costly (eg the fastest file copying tools are those that buffer data - costing more RAM during usage). Plus let’s not forget that syscalls are expensive too. But that’s the trade off you take and that is what is advantageous for the perpose you’re targeting nnn for.

So there really isn’t a right or wrong answer here at all and memory usage is in fact only a very small part of the equation (which is what the other projects author what trying to say).

As someone who is looking for a new job, I share your experience: all the recruiters that contacted me insisted on doing it by phone. They also won't tell you the name of the company at first, for fear of you bypassing them and going straight to the company's website.

That said, all calls I've had were from actual, honest recruiters who offered me actual jobs that exist and may fit my profile. I'm assuming that asking for phone numbers is how they filter candidates who are not really interested and make them waste their time.

I work in chip design, and we certainly don't design for planned failure, but we do design for 20 year reliability. This means we over-design to ensure reliability up to 20 years. If a market does not need such longevity then it would be reasonable to design for less time, to ensure you are not over designing. Chip deign is all about trade offs - power, area, performance, reliability, flexibility, integration cost, high/low temperature operation, yield, etc - and designing for 20 years certainly impacts this trade off.

At the end of this post you will get a cheat sheet of the 10 common gradient descent optimisation algorithms.

Using more readable notations, I will walk you through how the vanilla stochastic gradient descent slowly evolved into the popular Adam optimiser and others. I also came out with an ‘evolutionary map’ of the optimisers to visualise this.

The motivation for writing this post is that there is a lack of simple-to-read equations for parameter update and a compiled list of these optimisers.

Hopefully this benefits the community.

> Some program executables are multiple megabytes in size these days

I have shared the figures from my system right now in my earlier comment. The memory required for the meta info is extremely cache-able.

And yes, let's call it a day now. In fact, I am happy we had a very informative discussion towards the end. This is what I expected from the other dev and you from the very beginning. I am always ready for a productive non-abusive technical discussion. And if I find someday `ncdu` takes comparable/lesser memory than `nnn` I will update that data verbatim as well. But I wouldn't take uncalled-for shitstorm in public forums from strangers lying low.
First: most common baking recipes use all-purpose flour, which is around 10% protein. This type of flour is widely available and is best for most cookies, quick breads, some types of cake, pancakes, waffles, etc. It's also acceptable for enriched bread doughs (because gluten development is going to be inhibited anyway) and for fatty/laminated doughs like typical pie crust or puff pastry (for basically the same reason).

Bread flour is 14-16%. It will be explicitly called for if necessary. It's more of a specialty product, but it's often available in grocery stores. You'll mostly find it in more 'artisan' bread recipes, especially lean European-style breads like baguettes, ciabatta, etc. Works fine for enriched bread as well -- probably better, but not so much that I'd run out and buy it if I was out if I had AP flour on hand. Useless/counterproductive in basically everything but bread.

Cake flour is a low-protein (8% or less) flour that is more finely milled and is usually bleached. It's suitable for cakes and for biscuits of the Southern variety.

Finally, self-rising flour is usually an all-purpose flour that has baking powder (chemical leavening) mixed in. This makes it more convenient to use for a lot of common American baked goods -- pancakes, waffles, and biscuits, in particular. But it also is unnecessary/harmful if you're using a recipe that doesn't call for baking powder. ('Pancake mix' is similar, but it also contains baking soda and sugar. Just add milk and eggs.)

That was long, sorry. Regarding your second question: jam is a common topping for biscuits, but clotted cream is not a commonplace food in the US. (More's the pity.) One would usually butter a biscuit before adding jam. Or honey, if you're me. Or sausage gravy.

while its nice to have the fact about why this article has a few slight issues namely to do with the articles need to reference samsung phones which are in fact not that popular in japan, from my experience the majority of japanese people have one of 3 phones, an iPhone, a Sony Xperia or a flip phone, the article then goes on to say that the galaxy s5 set the precedent for high end waterproof smartphones when it was actually Sony who set the bar for IP rated phones with the original xperia Z in early 2013

also the line which mentions the s5 is talking about non removable batteries, the s5 actually did have a removable battery but there was a rubber seal in its back cover (a feature i believe first seen on the galaxy S4 active) the s6 was samsungs first flagship to ditch removable batteries

Ask HN: Which (large) European companies let me work on Linux?
My current workplace cannot offer much in the way of progress, so I'm on the look for something in Western EU and Switzerland.

I detest using Windows 10 for eight hours a day of my life, and would prefer a company that uses Linux desktops/laptops, or offers their employees a choice.

Any ideas where to look, company names maybe? Targeted field is test automation (although I can get into data science too), and I don't mind working in huge firms. In fact, I've been doing that all my life.
But "filtering out" would just need to be reducing ad targeting, not suspending the accounts, so some level of false positives might be fine if you can get a low enough false negative rate. The goal of the companies in this hypothetical is to limit systematic statistical detection of ad targeting, not to suspend automated accounts. If a small enough percentage of human users' ads are less/not targeted, no big deal.
Why does this use all the mathematical function from scipy instead of the built-in math? Are there significant benefits to that?
This feature exists under linux as well, it's called `suspend-then-hibernate`. See [0] for more details.

> Zhima Credit’s algorithm considers not only whether you repay your bills but also what you buy, what degrees you hold, and the scores of your friends.

I think you misunderstood what this means. It means when taking loans, the algorithm takes into account your score as well as your friends. This assertion in itself I must say I didn't find from any other sources.

This, even if proven to true, is completely different from what you are suggesting (i.e. your friend's score affecting your score).

Also, this Zhima Credit is just a private owned, part of the system which focuses on financial well being of individuals, it's not linked to other component of the system. Other social score components might not have this network effect.

When I first read it, I felt he was trying to find a solution for a problem that doesn't exist, that of; 'given humans are conscious and animals are not, what mechanism could bring about an incredibly sudden evolution of consciousness out of nowhere?'

The answer being that there was not a sudden evolution of consciousness out of nowhere. Human conscious states may be greatly more reflective that other animals, with a greater proportion of our neurons experiencing memory than sensory data, when compared to, say, a squirrel. However, the fundamental aspect of direct awareness is a shared trait, we are just directly aware of a far greater magnitude of internal states than the squirrel.
Microsoft may have better products or cloud services, but I’m not sure what’s the takeaway here. $23 vs $26.7 billion... okay, interesting... now tell us what share Amazon has vs Microsoft. Is the difference enough that Microsoft is a little bit behind or at this difference rate, would it still take Microsoft 3 years or 10 years to catch up? Maybe help understand what’s driving that.

Author also wrote this article, which if you look at his list of insights on why Microsoft is positioned better, has no substance. It reads more like an ad.

But that’s what you’re storing in the system memory, not CPU cache. Ok let’s say the kernel does cache recently accessed memeory in the L2 cache, you’re still competing with everything else - particularly in a multi-user or multi-threaded system. So that is not going to stay in L2 for long.

You’re making so many assumptions about the host platform and they simply don’t stack up for the majority of cases - it’s just that most systems are fast enough to hide your incorrect assumptions.

Also your understanding of how file system caching works is completely off. Granted that’s not something most normal engineers need to worry about, but given the claims you’re making about nnn, I would suggest you spend a little time researching the fundamentals here.

Edit:

They are actually from numpy, scipy just re-exports them, so they work with numpy arrays which the built in maths would not. I guess the author writes a lot of scientific code, so is in the habit of using them.

Numpy arrays are much faster than python lists etc for maths and matrix operations, (e.g. multiply this 1000 element vector by 2), which are common in scientific and engineering code.

>There are people today who hear voices, but they are a minority and we label them as mentally ill.

The sane ones know better than to tell people that they hear voices.

>"Research supports the view that hearing hallucinatory voices is not by itself an indicator of mental illness. Estimates of the percentage of people in the general population without a known psychiatric illness who report auditory hallucinations vary widely. One review of seventeen surveys from nine countries found prevalence estimates as low as fewer than 1% to as high as 84%. Estimates of college students who have reported hearing hallucinatory voices have ranged from 13% to 71%. The wide range of estimates can be attributed in part to differences in definitions, survey instructions, and other methodological variations. Taking into consideration such methodological differences, some researchers estimate the prevalence of hearing voices in the general population to be between 5% and 28%, with 75% of people who report hearing voices to be psychologically healthy. Research suggests also that the prevalence of auditory verbal hallucinations varies by gender, age and culture."

Surely the hypothesis has be to rejected in all its specificity but what new hypothesis can be proposed in the negation of the previous one? Could it be that the shift happened but not in the precise time or not all at once or the shift manifested in a more individualistic manner instead of a collective manner? Precisely in Lacanian psychoanalysis the symbolic consciousness (language) emerges as the reaction to an external traumatic encounter with the chaotic impossibility of the real. The hypothesis of bicameral mind may not have much scientific value but isn't it interesting to coincide so much with structuralism?

Ryanair, Hamiltonian Cycles, and using graph theory to find cheap flights
Good question, it depends on a few factors - e.g. BTI is aging that alters the transistor performance over time when a transistor has a fixed bias, so if you've loads of margin for this it should not impact you, or you can mitigate by periodically altering the bias to recover. TDDB is an issue at higher than normal voltages, so of the environment is controlled this can be avoided. For high reliability situations older process nodes are usually used which are less susceptible to these failures, and the environment is well controlled. Space has other issues like much higher probability of random bit flips, so design for space is challenging. Note our 20 year lifetime also assumes worst case conditions, so I'd wager many of our chips would last much longer in practice.
It makes sense to me - public privacy backlash tends to be limited to what they can understand is happening, and for the most part that is only really concerned with what you are actually sharing rather than what they can link to you via metadata and other dark patterns. Hell a lot of that stuff goes over my head too - the general public just isn't aware of how this works behind the scenes.

People put personal stuff on Facebook, and are more guarded about what they put professionally on LinkedIn. People approach LinkedIn as more of more of a two way selling relationship. They have a better feeling they know what they're in for.

Space Infrastructure Servicing
Thanks! It's something I have planned for when the platform is bigger in terms of users. Currently it has 900 (close to 1K, insane for just 2 days!), so if I split the categories more, many would be empty, making it difficult to find users in general. On top of that, more categories means more work for the users to select their desired categories. Overall it doesn't seem worth it for me currently.

What are my future plans in this regard though? When the site gets past 1K users, I will start brainstorming and developing a new way for users to select their categories. Likely through a textbox vs multiple checkboxes, where people could type the areas they are into and they would autocomplete. I'd like to also let users suggest categories, eventually maybe even let them create their own interests. Could be exciting!
I'm not sure if they ever did a scientific study on this, but you can choose your accuracy by playing with the scale of the plot.
