I agree with you on back-testing. Trying to model order book dynamics across multiple exchanges accurately is something of a fool's errand (especially in pro-rata markets). Running stuff in sim generally lets you iron out flaws and then you can just plug and play to see if it pays. Heh, I used to just plug and play directly with small size as a test rather than using sim since my firm didn't have a usable sim set-up at the time. Just put extremely limiting risk limits in terms of order sending rates on and then cut it off it loses too much in the experiment and move to the next one (yes, this did make strategy choice pretty path-dependent...).

RE rate limiter: For this dude's implementation I don't think it matters. He's using IB (a retail broker) for his data rather than the direct market feed. IB sends a sample of market data rather than every single book update and I think they do it at a rate slower than ~10ms so he probably won't run into problems. Heh, I remember some fun times figuring out the optimal way to handle getting spammed by the exchange. It is a neat industry, but kind of makes you feel a bit like a societal leech some times (I know, we're risk salesmen making markets more efficient and all...).
it should be fun for kids to start learning to code. but then, the move things around like that may do more damage than good on understanding multicore :)

The problem has to do with cross-section -- these satellites will each be small, a few hundred kilograms each. In comparison, cubesats are 1-3 kg, and big satellites, which are most of the existing ones, are a few tons of mass each.

Also, with satellites at 1,100 km, they'll be above all the crap in LEO.

My understanding is that the prevailing hypothesis is DID is in most cases linked to severe childhood trauma or abuse. It seems disingenuous not to mention that in this article.
This article is intriguing.

From what I have read, multiple personality disorder is most common in very intelligent women who were both sexually and physically abused from an early age, over a long period of time. I was abused from an early age, over a number of years. When I began therapy in my twenties, I would dream of six sisters, each was an age at which I had been particularly traumatized. Over time, some of the dream sisters melded together and I dreamed of four sisters. I eventually dreamed of conceiving a child -- conceiving a new self.

I was in my late thirties when I stopped feeling fragmented, when I finally felt whole. I never had separate personalities, but I suspect the abuse I endured stopped short of producing MPD. I wasn't splintered to that degree.

I have two special needs sons. I always told them their traits had good points and bad points. I did not communicate to them that they were disordered. I believe it helped them deal constructively with being different and helped them not feel broken or stigmatized. So I have sympathy for the point of view that multiples are just different and not disordered, though I feel clearly that my sense of having various personas was rooted in trauma and I feel clear that healing my trauma is what made me feel whole and unfragmented. So I find the idea that there are people who are multiple who do not view it as a disorder intriguing.

Some time last year I read a bit of Religion for Atheists[0] which touched on some of the same contents. I came away with a certain sense of being condescended, but also some interesting ideas along these lines. If you haven't read it, it may be worth looking up at your local library.

Basically. Though it is a pet peeve of mine that they refer to "Taylor Swift" as having done this, as if she was sat at the Spotify admin interface deleting albums. It was her record label that did it - a company that, by coincidence I'm sure, is looking for a buyer.
I think perhaps a better phrasing is 'write simpler code', code that expresses what it needs to as directly as possible, without unnecessary complexity.

This code does tend toward smaller more compact expression, but you're chasing the simplicity more than the literal absolute size.

Traveling? Ditch Your DSLR for Mirrorless Cameras
My first thought, here, was "Well what about the speed of light? Wouldn't that cause satellite internet service to suck, just like it does now? And isn't that why news correspondents are always delayed?"

But then I did the math:

Speed of light = 186 miles per millisecond. Satellites orbit at about 380 miles above earth (Source: Hubble).
So it only takes ~4 ms for a round trip to a satellite directly above?

I did not know that. Weird, wild stuff.

If someone knows specifics about why satellite communication is currently so slow (both internet and video), I'd be interested in the EL5 version.

I am not picking my numbers randomly. On a x86/x86-64 Linux kernel, one socket (one connection) will use at least one 4kB physical memory page. So if userland also allocates one or two 4kB pages for its own needs, you need at minimum 8 to 12kB per connection. That's why I quoted ~10kB.

The minimum theoretical memory usage is 4kB per connection: 1 page in kernel space, and nothing on the userland (eg. you use zero-copy to txfer data between sockets or to/from file descriptors).

At Google, our SSL/TLS overhead per connection is 10kB: https://www.imperialviolet.org/2010/06/25/overclocking-ssl.h...
I was thinking of just this for our 'send around' deck, and then if we were doing an actual in person pitch, then to use a pitch-deck.

Any chance you can share your infographic? I'd like to see how it wasy laid out.
It looks like the approach was different: instead of having several thousand of small and 'cheap' satellites, they were aiming for an expensive and big one.
Funny you say that. I just had a conversation about a meeting I was involved in a few years back when our EE's didn't understand why we thought it was a spectacularly bad idea to design our own Pentium-class CPU boards vs. just buying them off the shelf.

How Utah Became an Epicenter for Get-Rich-Quick Schemes
I bet they both started around the time CoffeeScript started to get big -- it showed there was a market for compile-to-js-but-almost-js langs.
First things first. It is possible to get off this shit. I was on kolonopin for almost 7 years, never at doses lower than 2mg as well as Xanax. The Ashton manual is invaluable. So is the Benzo Buddies forum. Be aware that most doctors don't know anything about benzos. In my experience, in the US at least, you're on your own. Even psychiatrists have no idea how to taper. Most have no interest in helping their patients taper because they also do therapy and hate to lose clients, especially on the west coast where these things are typically combined.

General practitioners or even psychiatrists have no business prescribing this for longer than a week without fully discussing the inevitable dependence and taper plans. Any doctor who does not do that is akin to a murder on my mind and should be treated as such. This has been my experience with over a dozen doctors in two different states in both coasts.

It's a horrible situation this, but it is possible to escape. Best of luck to everyone who is struggling with this. I was able to taper off in a few months with few side effects. That was incredibly rapid for benzo withdrawal. I'd definitely budget at least three to six months at a minimum with the idea that it could be a lot longer. There are some scary stories out there but it's possible, given time, to do it gradually enough that it's not horrible. It's now been almost a year and a half and I haven't looked back since. The one blessing is that after the taper I've had no cravings. I had to give up a life I had spent seven years building and return home with no money and no savings and no job to taper, but it was worth it to get my life back.

The "doctors" who prescribed that shit, I will forever wish they lose their job. In my opinion, jail would be the only proper place for them. But it's big pharma. Never going to happen while the profits roll on. After all, they are indeed the most ruthless drug kingpins out there.

Sounds like it's extremely well named, then. LispyScript is to Lisp as Javascript is to Java: an entirely different language with different syntax, semantics, standard library and performance characteristics, but with just enough superficial similarity to provide plausible deniability for the name.
My interpretation is that the water continues to accumulate, so the problem isn't only what to do with the existing contaminated water, but how to avoid having to build an endless amount of storage tanks.
Unless the content you're accessing is hosted on the satellite, it will have to jump several more times over a much longer distance for a complete round trip. Can you factor that in to your estimate?
Ah yes, the famous NIH syndrome. Why use something that can do thousands connections per second when we can pump our chest while doing it in node and falling apart in hundreds?!
I'm a bit confused by the question. On the one hand, it seems like it is targeted at users, since it's about annoying behavior. On the other hand, the options are technical and each of them is great when not leading to the user experience sucking and all of the suck when they lead to the user experience sucking.

My preference then is for software that doesn't suck and the way to get there is by testing implementations rather than picking a strategy based on personal bias. CSS should make for a better user experience, and that means that nobody should be aware of it.

Good luck.
If it's just tritiated water, is there a good reason it can't just be dumped into the ocean? It won't bioaccumulate, right?

Ideally we could also control the cooktop and at least on older electrical models it should be possible to hook into the circuitry that the knobs are attached to. Without automatic feedback loops such devices are less convenient but still enable better understanding and communication and prevent mistakes. In the salmon example, you might perfect cooking your fish, invite a couple of friends and suddenly fail because you learned to regulate the power output for a single serving, not for a more crowded pan and don't know how to adjust because you don't even know the temperature profile of your perfect fish. Of course one can learn to cook by sound, smell, heat, touch sight and taste and I value poetic recipes but that does not diminish the value of temperature controlled gear.
This is really cool, thanks for sharing it out!
Why You Shouldn't Emulate Silicon Valley Companies for Startup Success
We use stud for tls termination at work. It's because we can put it in front of all of our various http servers and get consistent tls support. Almost all of the services have the same stud config, just different certs. Stud is very amenable to running in a jail too (so we've limited the damage of the next openssl vulnerability), so the config references one cert path, and we just put the right cert for the machine when we assemble the jail. The only other usual difference is the number of localhost IPs to use, so the script detects that as well.

Haproxy would probably work fine too, but seems a bit overkill for running a local termination proxy.
Spacewalk: Free and Open Source Linux Systems Management
I think the biggest problem is that it isn't just a few tanks of water, it's a constantly growing amount. It's expensive and impractical to keep building tanks, it's expensive and impractical to filter out the tritium, and it's questionable whether just pumping it out to sea is acceptable (I imagine that if they were able to dump it far into the ocean away from any land it would be more palatable, but that would also be, you guessed it, impractical and expensive).
Here is a quick clone of this project for Linux using the STOP and CONT signals:

#!/bin/bash

currentProcess=$(xprop -id $(xprop -root | grep -F '_NET_ACTIVE_WINDOW(WINDOW)' | awk '{print $5}') | grep -F '_NET_WM_PID(CARDINAL)' | awk '{print $3}')

state=$(grep 'State:' /proc/$currentProcess/status | awk '{print $2}')

if [[ "$state" == "T" ]]
then
kill -CONT $currentProcess
else
kill -STOP $currentProcess
fi
Well, IANAPP but a quick google skim shows that the half-life of tritium is 12 years, roughly. That's a long time to store something to get down to levels where you could feel confident dumping the water out, or accepting the risk that it would end up in the groundwater.
That's what the article says but I guess there's still concern. The disaster has cost $150 billion.

http://rt.com/news/183052-japan-fukushima-costs-study
usually when you do this size goes up. the number of files goes up.
As they say in the article, tritium is usually not considered a health hazard, but organizations are starting to question that standpoint. It would, as they also say in the article, be politically unpopular to do so regardless of what the actual effects are.
Because, communication satellites are not currently 380 miles above earth but 22k miles above earth.

Is there no room for competing networks offering global internet access?
Well, there's two questions, right? The first is how harmful tritiated water is to begin with. It's a low-energy beta emitter and, because it mixes quickly and permanently with water, it's eliminated quickly as well. You wouldn't want to go out of your way to drink it, though.

The second question is, what is the environmental impact of dumping it in the ocean? No matter how dangerous it is, the ocean is gigantic. So you want to know: are there environmental processes that concentrate or amplify it?

Later: I had to leave before writing this last part.

Obviously, all things being equal, you'd rather TEPCO keep spending money to keep this stuff out of the ocean. But are all things equal? Is it riskier to try to contain it?
Ask HN: Help I'm building my hardest software project yet. Struggling
I'm building the most challenging software application I have yet built. I'm a one man band and I do everything from back end coding to front end coding to deployment.

I'm trying to do it right, which means learning and using technologies that I am unfamiliar with, but in the long run will make me more productive.

I have a full time job as well as children so I've got alot on my plate.

It's extremely rewarding emotionally because I love the project and I am learning alot and I believe it will be something useful.

On the other hand it's taking alot longer than expected (why do I ever expect anything else?) and I'm getting exhausted from the brain taxing range of new technologies I need to learn.

I am at the point that I have proven all the key technologies and actually done all the hard technical things that need to be done. Now I need to tie it all together into an integrated working application and get it out there.

Anyone got words of encouragement to push me through to get this finished and launched? I can feel myself physically slouching under the weight of the effort.

For those that don't know, varnish was always a bit reluctant to take on the challenges of TLS termination. They traditionally had more of a 'do one thing well' policy. Here's a good description of their reasoning around that:

https://www.varnish-cache.org/docs/trunk/phk/ssl.html
Look at your kids. If this would be a means to allow you to spend more time with them, then you know it is worth pursuing.
As opposed to current pipe dreams:

* gigafactory under construction

* freemont factory producing ~50K vehicles/year

* spacex successfully, repeatedly delivering payloads to orbit (and successfully demonstrating their crew escape vehicle recently)
Could you create robust, modular storage vats that double as interlocking elements of a sea-wall to hold back future tsunamis? I imagine it'd be expensive but you're killing a few birds with one stone. If containment in a single vat fails then the radioactive water is dispersed in a vast sea as opposed to a small land area.

I also wonder if you could blast pellets of radioactive waste with a very big laser like the one at the NIF [0]. I don't know much about physics so I accept this could be a disastrous or futile idea but if anyone can comment that would be great.

> The second question is, what is the environmental impact of dumping it in the ocean?

This is the wrong question. The relevant question is "what is the political impact of dumping it in the ocean?" and the answer is "devastating".

No matter how scientifically sound the solution, "dump it all in the ocean" simply can't happen.
> No matter how dangerous it is, the ocean is gigantic.

That's kind of a dangerous precedent to set. If we can dump radioactive water into it, why not oil?
