The reason why is crypto RNG are much slower than something less secure. It really depends on the application, but in the code I wrote today a significant fraction of my application’s time was spent in the RNG function. By replacing the RNG I managed to speed up my code by a bit over 2 fold. I am not doing crypto work so this is great.
I done something similar some months ago. Maybe this helps someone though it should have same content: http://nbviewer.ipython.org/github/bodokaiser/data-science/b...
Your point is valid but not a reason to downvote - on HN downvotes are supposed to weed out aggression, trolling and other unwanted behaviours, not to express disagreement.
Have a look here: https://en.wikipedia.org/wiki/Orbital_mechanics

The short version is - for the most part these trajectories can be calculated with a decent degree of accuracy with relatively simple equations. Rocket engines tend to give acceleration in short bursts (which simplifies the computations a lot as well), so New Horizons was launched out of Earth orbit at about 16km/s and since then has only fired its own engines for short correction burns.
>As I type this my comment sits at 0 points, as does every comment I make even remotely critical of bitcoin and the blockchain. Why does HN hate people that are critical of bitcoin?

No offense, but you don't appear to understand these subjects very well and you seem to have limited knowledge of them, yet you persist in commenting on them and thereby spreading misinformation.

Possibly you believe you understand the subject better that you actually do? You're not the only person falling into this trap, and I'm sure you intend no malice, but this may be why you get a few downvotes.

I happened to notice this a few days ago, when you made a statement about bitcoin that a few seconds on Google could have shown you was poorly-informed. That's OK, everyone makes mistakes like this sometimes, but when I pointed out the error, you unfortunately tried to divert attention with an extremely weak strawman argument, and then just stopped responding. It's tiresome.

There are many, many criticisms that you could make of blockchain technology and bitcoin, not least of which is that nobody even knows for sure if they will work as intended as they scale up. There's no need to leap into the debate with such poorly-informed statements
Thanks :-) Glad you enjoyed it.
Are Delaware appraisal rules being applied, and interpreted under Delaware law, in the cases discussed because Ancestry.com and Dell are both Delaware corporations, or because the entity that actually owns the shares is a Delaware corporation?

While many big public corporations are incorporated in Delaware, there are also quite a few that are not. About 36% of the Fortune 500 are not. Some prominent tech examples are Microsoft (incorporated in Washington) and Apple (incorporated in California).

"One of the great missions for the 21st century could be FOCAL — a space probe sent to the Sun’s gravity lens some 550 AU out."

For comparison, the "straight line" distance from Earth to Pluto recently traversed by New Horizons is about 31.9 AU. Thats about 3 billion miles, and took nearly ten years.

550 AU is a long walk.

When people call taxi they don't hope to see interesting human to talk with, they need a car to move them from point A to point B. This driver expects his clients to be wondered about him or his life, when they don't expect it and often don't want to spend their time to be somebody's psychotherapist.

It's sad he is so lonely, but taxi is not that place which should fix it - maybe dating sites.
I'm kind of with you on this. 6-8GB RAM for modern development has been more than enough for most requirements for at least 5 years. From my point of view, 2GB on an android smartphone seems to be a similar amount.

Some interesting points raised above about heaps.
> Why not? It's perfectly valid to use a secure RNG for non-secure purposes.

It's much slower. Yes, in your application it was a fraction, but they are still much slower than non-secure RNG's.

The US was able to ramp up the shale / fracking oil boom and nearly double production in just seven years. It's a key that can be turned at any time if oil goes above a certain level. Exploration isn't an issue, they know where the oil is, and can tap into it at any time. Take for example the Spraberry/Wolfcamp field in Texas, it's almost entirely untouched, and is one of the world's largest oil fields.

Natural gas has a massive, perpetual domestic demand basis. That isn't going to change unless the price of natural gas goes up three or four fold from here. Coal plants are being shuttered, coal has gone from ~45% to ~30% of US energy production in a decade, while natural gas has become the #1 energy supplier in the US.

The US has essentially infinite natural gas, as far as consumption in the next hundred years is concerned. It's a non-issue in any direction.
What Happens When Struggling High-Schoolers Take College Classes
Looks like a very good and fast PRNG. How could it possibly achieve higher statistical quality than a secure PRNG? I guess that depends on how you define quality.
One of the benefits of a PRNG is reproducibility. If you are doing a monte carlo simulation, then you can get good results while still starting runs from predictable seeds. (e.g. [0,1,2,3,4,...])

This gives you both good quality random numbers during the simulation run yet lets others reproduce your results and expand with more results if required.
> So, let me ask you a question, you prefer a browser where stuff is disabled by default and you enable them at your own will? Can you give me pointers into what about discovery of said features?

> Thinking the other way around, what about a browser where features are enabled and then you disable what you do not like? Why is that bad in your opinion? The customize menu that allows you to reorder and remove features is not enough for you?

Not sure if you understood me right. All I stated was that if it had been an extension that shipped with Firefox and turned on by default, it is easier for the user to turn it off or remove it than when it is a part of core Firefox. Please see my above comment for details. I did not talk about browsers with features turned off by default.
Maybe someone wants to unite to build something bigger. We have awesome quality messaging, but it is nice to have voice/video. Also for voice/video it is good to have messaging too. Maybe someone building encrypted email provider? Or just email provider? Email and Messaging are good together. File sharing? Aero FS? We can integrate messaging in any service, and it can look like "chat heads" of Facebook. Imagine, from any task in Issue Tracker you can open conversation with an author of issue/comment? Nice! No one has done this yet.

"Actor" is named after Actor Model, where Actors are small valuable pieces of code that can integrate with other Actors of different kinds. The same idea can be for services, build deeply integrated experience of tools that we are using.

This is dreams, but i have not evidence that they can't be true.

Considering the definition of a plutoid is effectively "a planet further away than neptune", I'm inclined to shun the plutoists and agree with him.
I disagree.

I do mainly Python / Django stuff these days, but if I have some syadmin type tasks, I will happily switch to Perl. It has better build in syntax for quick stuff, like renaming a bunch of files. Built in regexes are so much easier than farting about with object based regexes. Text processing is better. Stuff like file gobbing is built into the language.

Its easier to shoot yourself in the foot with Perl, so I'll choose Python for stuff that is more long term. It really depends what you want to do.
Neither you nor I nor the original author have hard numbers about who knew what, so all of this is conjectural. But I was addressing a different point, which was my difficulty in reconciling the author's position that "a developer from 1975 could ... feel pretty comfortable" with modern programming languages because the underlying techniques existed already "in some form", while also implying there would be no developers from 1975 who would feel comfortable with version control control and library ecosystems "in some form."

It's surely true that not all programmers now know about closures, just like it's unlikely that all programmers in the 1970s knew about them, so this isn't a universal claim. Nor did I think it was a universal. Rather, I think the author's point is that those with interest and experience in programming languages would have known the topics. That is undeniably true.

My response was to point out that those with interest in software engineering techniques would have known about version control systems and library ecosystems "in some form", because I can point to people who were SCCS, and people who were involved in library ecosystems.

"Python isn't suitable, or at least is arguable a poor choice, for some tasks."

That inarguable. Java isn't suitable for some tasks either. Nor is the statement that the C standard library is smaller than Java. But why is it that Java's standard library "really kicked off the trend of wide scale reusability"? What was the size magic threshold? Why did previous languages with a large set of standard libraries (I suggested Object Pascal, eg, from Turbo Pascal 5.5) not kick off that trend?

"There also wasn't a good way to distribute"

Again, I don't think you are discussing the same point I am. The author wrote "The magic part is simply that open source licenses like Apache and MIT lower the friction to trying out a new library."

My point was that in the 1970s that magic part wasn't relevant. Instead, and I agree with you, the "magic part" for a 1970s developer is instant network access, and not open source licenses.

I think licensing is much less magical... and even in the 1970s there was already ARPAnet, email, and UUCP, so again it's more a diffusion process than something "magical" or unknown in 1975.
Just wonder how long they will manage ? Their competition is fierce and cloud storage is indeed an additional feature of their competitor products.

A bit like standalone digital camera losing out to smartphones despite obvious quality difference. In this case, dropbox does not even have an obvious quality benefit: syncing is a bit of a lemon market and in any case it works perfectly for most people the majority of the time.

I'm both an iCloud and a Dropbox customer. The fact that I chose to pay for iCloud despite paying for Dropbox is my anecdotal evidence of the perceived value of iCloud "other services" (which I admit is Apple ecosystem prison - just sweet enough a prison you don't want to break free). I trust Dropbox - but I know that eventually, if iCloud does not betray me for a while I will be tempted to save some money on it.

"Many who work in tech are living their lives as if it's the carefree Roaring 20s, while I'm more or less stuck in the Great Depression."

Of course, the roaring twenties were themselves times of relative inequality, and that name only describes the excitement, culture, and affluence of the urban rich of the era. The author seems to be describing the modern day euphoria over the power of the tech industry to make a new world as similarly one-sided.

Is it true that, at Google, product managers have to convince engineers to work on their product?

For context, this answer on Quora[1] suggests that the product team does not report to the product manager and don't have to do anything they say, so the product manager has to convince people if she wants to get things done.

The very important difference is that at a job you get paid regardless. You can even shift your mental model such that "it's just a job" and start leaving the crap 'at work'.

In a startup (esp if it's your own), the psychological and emotional stakes are significantly higher. Also, there's no reason that politics can't find their way into a startup you're running. You just might not notice it because you've positioned yourself at the top of the tree of monkeys.

>the only color system produced entirely from measurements of human color perception

What is CIE LAB then? While Wikipedia states that it was influenced by the Munsell color system, I don't think it was directly derived from it. Also I would argue that it is in common use.

On the other hand these measurements measured the local distance between colors (based on distinguishability) but nothing guarantees that the space of perceivable colors is Euclidean in this metric. So you can fabricate an Euclidean space of colors where the Euclidean distance is close to the perception distance, but it may never be perfect.

Side note: there is no perceivable color space to "rule them all", even if you can fabricate a perfect one. For upscaling images it could make sense to use a perception based colorspace for interpolating pixel values, however for downscaling you should use a linear colorspace (note: sRGB is NOT linear, almost all desktop software downscales wrong [2]). It causes kind of a hassle that distinguishing colors of large areas is happening with a strange metric, but if you are looking at objects with fine structure (like your LCD monitor) then the color mixing happens in a linear colorspace.

Is the conclusion just that: when implementing a TLS stack, some people call it 'done' when they can get HTTP over TLS mostly working. You will find implementations in the wild that omit any (or all) of the code that is required by the spec for security but not for interoperability.

This is like the idea that the C source code found in the wild is anything that was accepted by some compiler at some point.

I wonder if it'd work better with a leaky ReLU. Somebody wanna try? It's a _very_ simple mechanism. [1] Basically, instead of a sigmoid, let f(z·w) be the activation due to inputs z and weight w, then a(z) = z·w if z·w > 0 else 0.01 * z·w. Sigmoid for activation have several problems, most notably they suffer from vanishing gradient problems with bigger networks.

OTOH the whole appraisal process is a Delaware thing (and arguably encourages nuisance lawsuits) - by incorporating in another state you could avoid the process entirely.
I should note that I am over 40 and overweight but am losing weight on a fairly regular basis. My goal is within another 2 years to drop down to a manageable weight and hopefully reduce my intake of metformin altogether. High-blood pressure runs in my family, so I think its unlikely if I lose a lot of weight, that my use of high-blood pressure control medications will abate.

I start every morning as follows:
1. 2 800mg Nootropils
2. 1.5 Wakalert Tablets
3. My diet pills from the doctor here in Thailand
4. 1 Herbessar for my high-blood pressure

Wash it down with a cup of coffee.

Then an hour or two later, I start drinking iced green tea with no sugar and eat a breakfast with carbs, then I take:
1. 1 Hyzaar pill for my high-blood pressure
2. 1 Prenolol for my highblood pressure
3. 1 Metformin of my diabetes

Then, I have a yoghurt.

I sometimes have a snack of whole wheat crackers and hummus

Then, I eat dinner that is 2/3 veggies and 1/3 meat

My sleeping and work schedule are as follows:
1. I wake up between 10am and Noon each day
2. I go to sleep between 2am and 4 am every day
3. My workday starts between 11am and Noon
4. I take a break from 4pm/ 5pm to 8pm/9pm each day
5. During my break, I hang out with my kid, watch TV, read books, write, do strategic thinking for my businesses/ jobs, eat dinner, and take a walk.
5. My second shift starts 8pm/9pm to Midnight/1am
6. Then I read, play games, watch tv, etc... until I go to sleep

Then before I sleep, I take the following:
1. 1 Metformin
2. My nighttime diet pills

I work 7 days a week between 6 and 10 hours a day, mostly around 7 hours.

Nootropics are just a small part, but I consider them a very important part. Since, I do lots of academic editing, I find the quality is much higher under the influence of nootropics then not. But, my use of nootropics integrates them into my lifestyle.
