Had the unique experience of entering into Utah where the highway speed limit was 80mph (~ 130 km) and had no desire to drive any faster than that, it was a very comfortable speed for that road and everyone was going about the same speed so it didn't clog up or get a lot of people changing lanes to adjust.

For a long time in Nevada there were no speed limits (prior to the 55 law) and we'd drive up 395 toward Reno at 80 - 85 mph which was just fine.

It seems like you just have to believe that making a faster limit won't ratchet people to 'limit + 15' where they are when it is 65.
Hi,

My name is Carl Sweet and I work for a company in Redwood City named Moka5. Your background looks impressive. I have multiple positions that may fit your background. Can you send me a resume to csweet@moka5.com?

Thanks

Carl
Ha, yes, good point :-) I didn't write about that, but I did take some pictures of failed attempts at that.

That's one of the first things I did, actually. After dumping the contents of the flash off, I went on Amazon and hit 'reorder' on the same SD card that I'd bought before. Unfortunately, it was not the same: in the picture [1], the left is the one I'd purchased this time, and the right is the one I'd destroyed. The deals that low-cost SD card makers get on NAND flash vary greatly from day to day, so they just manufacture based on whatever controller and flash combination they can get cheapest on any given day: even the same SKU is unlikely to stay the same internally very long.

I did also try soldering to the BGA pads on the damaged one [2] [3], but no joy: I imagine that there were some traces that went backwards on the board before going towards the controller (for instance, to meet the TSOP leads), and on inserting the SD card into my laptop, I still had no signs of life.

Generally, worth taking government reports with a grain of salt. I've participated in a few, and the standards are often much lower than peer-reviewed articles. That said, on a quick skim, I don't see anything that strikes me as being obviously wrong / overturned (FHWA was 1997).

But, I also don't see either source providing justification for driving faster. Both reports seem to accept this (in fact, this is about as close to pure physics you'll find in transportation engineering):

From the FHWA's report:

These requests are founded on public knowledge that crash
severity increases with increasing vehicle speed, because in a
collision, the amount of kinetic energy dissipated is
proportional to the square of the velocity. Simply stated, when a
vehicle is involved in a crash, the higher the vehicle speed, the
greater the chance of being seriously injured or killed.

and quoted by the BC report:

A driver’s choice of speed can impose risks on other road
users. Crash severity increases with increasing speeds because in
a collision, the amount of kinetic energy dissipated is
proportional to the square of the velocity.

Now, beyond this, there are some subtleties. Both of these reports state that crashes are more likely to occur when there is a greater delta between fast and slow roadway users. That's fine. They also talk about how speed limits are more likely to be exceeded where the roadway design encourages higher speeds. Emphatically agree.

So, now we are left with a policy question. Surely we agree that habituating people to breaking the law is bad. If people respond to a combination of law and roadway design (perhaps leaning more heavily on the latter), and we want behavior in line with law, what should we do? Ease the law or change the roadway design?

Normatively, for most roadways (especially those containing bicycles and pedestrians), I say we need to move more toward changing the roadway design to discourage higher speeds. On some highways, it might be appropriate to lift speed limits, though even then I'd tend to cast a cautionary gaze toward the Montana experiment that was referenced elsewhere in this thread.

Her point here was that its not necessarily harder being a girl ceo/ some things are different but it's a draw.

Her point was that these are minor details and that it doesn't change what makes being a ceo so difficult.

She wants to make it clear that being a woman ceo isn't some kind of amazing feat (though being a ceo in general is) and that she wants more woman to try it.
There would be a lot of evidence though. The fact that on multiple occasions items purchased with stolen credit cards were sent to you and you had not returned those items implying you were expecting them.

You'd have to come up with evidence to prove it wasn't you that ordered it and good luck with that.
fake?

The bit on privacy and nothing to hide put it over the edge for me.
I think her point is that the differences are irrelevant in comparison of the (common) challenges leadership positions generate, so it's not helpful to overemphasize them.

I didn't get this from the article, but are there no automated cameras in the USA? In Belgium there are tons (I pass 5 on the 10 minute drive to my girlfriend), but they're a joke. If people know the road they're taking, they drive however fast they like, until they get near a camera. They slow down until they're out of reach and then speed up again. Also only about 1/3 actually have a camera in them, but they get rotated every once in a while.

Actual policemen with a camera are rather rare - considering how much road we have - and they get reported to radio stations. Though they're not allowed to tell listeners where they are exactly, only which road they're on.
Exactly -- sure, you can still hide behind a truck and go 100 km/h all the time -- but most cars efficiency sweet spot is around 130 km/h, and driving at that speed leads to more dynamic, occasionally passing trucks, etc.

Ask HN: How to find a Manufacturer?
I'm a software engineer who is trying to find a manufacturer of game pieces for a Kickstarter project. The pieces are fairly simple, some acrylic with some printing. Unfortunately I know basically nothing about this type of manufacturing.

Is there anyone who has gone through this process that can give me a couple pointers on how to proceed?

Thanks.
> I have lived in a number of 'mental healthcare' institutions in the Netherlands for a few years. One of them was (supposedly) specialized in 'autism spectrum disorders'. My experiences do not match what you are describing at all.

I am not surprised in the least. If you're able to write then you're in a whole different (much, much more high functioning) class of disability than the people I was working with.

> By far the biggest harm to these people is done by the staff, who appear to be completely oblivious to how people actually think, and try to fit them into a 'treatment' programme.

Also not surprising--the facilities I worked at were very forward-thinking, and I witnessed some unbelievable behavior improvements through targeted autsim therapies, but in the past the state mental hospitals were notoriously abusive. Still, even with the best facilities, you're going to run into problems with staff when wages are less than ten dollars per hour (early 2000s, it's probably closer to 12 an hour now). Most staff at these types of care facilities could instantly double their wages if they got a job delivering pizza.

I don't know that those make a compelling argument for Yo, though. How many were worth that much money in their day, or would have become worth what they are without the cachet of the artist?

While it pains me to say it, there is case to be made for Yo as a work of art, if art can be accidental (I guess all real memes are accidental art in a way, and Yo's popularity seems memetic to me.) And perhaps the ephemeral nature of the medium works against it, but I seriously doubt anyone is going to care about Yo fifty years from now.

Damn that was bad design. I clicked the massive green "Try it now" call to action, fully expecting that to be the demo. Since that comes before the tiny "See it in action" link, and it moves me to a new page, I didn't see it. Next I tried just actually going towards the close tab button, but the demo wasn't already activated. At this point I would have hit the close tab button if it weren't for these comments.
Mentioned this in another thread and I'm still looking for researh around this topic:

A Dutch engineer once told me (back before 2004 I guess ) that they once raised the speed limit on the roads in Netherlands and found that counterintuitively, - average speed decreased.

His explanation IIRC was that

1. once people break the rules it doesn't matter how much

and

2. when speed limits felt more correct more people respected them.

this, according to him, meant that even if some people were driving faster a lot of those who used to break the rules now followed them.

I'd still love to know if anyone has any more pointers to research on this and I am fairly sure someone around here knows a whole lot. ( I got some unexpected input in the other thread already.)

Here are two blog posts I was able to find from companies who switched Mongo -> Cassandra:

http://www.fullcontact.com/blog/mongo-to-cassandra-migration...

The main selling points for Cassandra over Mongo are that it scales to more machines easier for handling larger workloads, and the write performance is better.
You have to be careful where you are when the boom ends. Dallas weaned itself off oil money in the late 80s/early 90s; ExxonMobil's headquarters is the only major holdout. It turned itself into a headquarters town, and is now turning itself into America's datacenter and a minor tech hub. Austin has entrenched itself as a second-tier tech hub. San Antonio is a major Air Force tech hub. Houston, while awash in oil money, has non-oil shipping, finance, and NASA. Only west Texas is so dependent on oil that an oil bust would be a major economic calamity.
Amazing work Jason!
What's up with your postings on semiotics/biosemiosis? Are you a theorist looking for discussion? Very few people are aware of the subtleties of the field, and it all too often becomes washed down. If you're looking for a really good, deep, introduction, which I feel doesn't dumb down the insight, consider John Deely's Basics of Semiotics.

Good luck and best wishes with your explorations.
As I said, to the extent that the article made the case for combining speed limits with roadway design, I agree.

However, the quote from the Lieutenant was clearly stating that speeding was not the problem. The whole article appears to have been either crafted or embarrassingly not crafted to muddle these two questions.
This might explain why introverts tend to think that everyone else is more extrovert than them, there's probably a lot more introverts than we realise but we're just less likely to meet them.

Just when I finally thought I would be technically ready for the kind of stuff I wanted to learn since I first heard of DEF CON (6th edition I think).

On the other hand I can totally understand how hard it must be to organize an event of such magnitude, fame, etc. and not going crazy in the process.

Farewell DEF CON.
I thought this was a decent parody of the corporate infosec mentality. DEFCON is hardly any different these days though, it's just good at maintaining the illusion.
DotCloud PaaS Joins CloudControl
Clicked to read how to increase the reliability of device drivers. Looks like neither one is an easy task.
Many of these properties no longer require the prefix for most browsers. For these properties having the webkit prefix only, without the non-prefix property to cascade to, is a problem. I recall many demos, examples, and live sites not displaying as expected in Firefox because the developer decided to use only the webkit prefix. If the webkit team were to start removing the webkit prefixed properties then those sites would have even more broken views.
I was involved in a migration from MongoDB to Cassandra at my last job.

We switched to Cassandra because of the control it offers over how your data is laid out on disk, and it's ability to not totally fall apart under load (in fact performing really well). It's also a lot easier to deal from an ops perspective.

I did a post about the migration here: http://blakeeggleston.com/migrating-databases-with-zero-down...
There are approaches. One is General Game Playing where the rules are given as a set of logic formulas that basically describe a state machine

http://en.wikipedia.org/wiki/General_game_playing

http://www.general-game-playing.de/literature.html

GGP is then about deriving knowledge about the game and its state evaluation using a) the rules directly, b) the represented state tree or c) past matches in that very game.

The other one I know of is a mechanism where you use reinforcement learning and assume one state in the beginning.
With more info, you start splitting the state into several states using decision tree split criteria, such as cross entropy, and you end up obtaining a game state tree together with the knowledge to play reasonably well. Problem: I don't remember how it's called.
The only device driver I wrote was in my advanced operating systems class in grad school nearly a decade ago, but I'll say amen to that :)
ECMP is used heavily in serving Anycast DNS worldwide; it's only the application to HTTP that's somewhat new. A high-end router can do stateless ECMP at 10s or 100s of millions of packets per second; it's hard to find load balancers that can compete with this.

BGP has heartbeats at usually 15 to 45 second intervals depending on configuration. If BIRD stops responding, the router will withdraw its routes.

BIRD can be controlled via a Unix socket. Usually people build a health-check daemon that does queries against the local app and communicates its finding to BIRD. Working through all of the failure modes here is tricky, but doable.

The ECMP hash is often implemented as something like a CRC-16 of (protocol, source IP/port, dest IP/port) modulo the number of next-hops. I suspect the trick to keep TCP happy is to try keep the number of next-hops (shards) constant for each route.

Interesting! Of course the Dutch are also leaders in highly designed shared streets that make the hippest of the hipster urban designers in the US swoon with envy. Unless we're talking about major highway facilities (and perhaps not even then), my hunch is that we're looking at some radically different street design.

Where are these slower roads though? If I were a cop, I'd be much more likely to pull people over for speeding in more residential areas, which tend to have these sub-55 speed limits.
I think it's pretty interesting that you advocate for narrower roads and short setbacks because you belive that on roads like this people are less likely to speed.

I don't know if people are less likely to speed on those roads; I think it is unlikely because growing up in a small town, people speed on backwoods roads all the time. Still, I'm not sure that this is the case.

What I do know is that roads like that are less safe, particularly if you DO speed.

So, unless you can show me that making a road less safe for speeding reduces the rate at which people drive, I'm going to keep thinking that that argument is like saying you can't give out condoms to kids because it makes them more likely to have sex.

Yes and no. Yes in that driving can be enjoyable, and a car can be an expression of one's personality or identity. (I for example own a MINI Cooper; make of that what you will.)

This is why, to successfully get all your nutrients from a plant only diet, you really have to understand the science behind nutrition -- at a very high level. Lots of book reading at the local organic food store and wikipedia articles is astonishingly insufficient.

Many of the health problems that this kind of diet createscan take decades to take do noticeable health damage and by then it's too late.

What's not fair about getting a speeding ticket when you are driving over the speed limit?
the article repeatedly mentioned: raising speed limits does not raise driving speeds on roads. humans are kind of strange in the fact that they drive at a speed they are comfortable with.

also, while that (faster = crash more) may be true, its not the only thing going on. it may be the case (and one argued in the article) that driving speed differences results in more crashes.
I'm afraid that you should have waited a phase or two before posting this on HN. I wonder if users will ever see your next phase. A tip for the future would be to better consider your moment of first introduction. All of the comments in this thread could easily be made by no more than 10 people outside your everyday test environment. Think about family, friends, neighbouring companies who haven't seen the product yet, etc. Just 10 and you might have altered your first introduction from not so much (except info) into a success.
Let's not forget that the speed limit was never about safety. It was about saving fuel in an oil crisis.

Where did I state that the OP should only determine present dollar value? I simply wrote "The OP needs to quantify what's at stake in absolute terms." Percentages are meaningless unless you have some idea of what x% of something is worth, whether today or tomorrow. As I wrote, it is possible to win a negotiation around percentages but lose money. I could fairly easily give you 25% of a company and structure the equity so that upon its sale, you netted next to nothing.

On this note, please recognize that figuring out what's at stake requires the OP to take an even bigger step back. The OP indicates that he was given a 10% equity stake in the company in the form of stock options when he was a contractor.

As a contractor, he would only be able to receive non-qualified stock options. The tax treatment of these is almost always less favorable to the recipient than incentive stock options, which can only be granted to employees. Now that the OP is an employee of the company, he may need to consider that the structure of his equity is sub-optimal. If there's justification for a negotiation here, the structure of the OP's equity could be just as important as equity amounts.

Further complicating matters is the OP's status, as it sounds like he's a nonresident alien. Cross-border tax issues can be very complicated and at a minimum, the OP should understand the implications of transactions involving his equity.

Bottom line: simply jumping into a negotiation over percentages is putting the cart way before the horse. The OP should seek the counsel of a qualified attorney and tax professional before he tries to address his concerns directly with the company.

I wrote a chess game on a PIC16c-something. It had 176 bytes of RAM and only a 8 level return stack. I implemented recursive minimax by managing my own data stack since the compiler claimed to not support recursion. Code size was IIRC around 2K. You could play it on a battery charge controller we were making via UART in a terminal program, it printed the board and accepted key strokes. It declared checkmate when it was a certainty but before it actually happened...
