Constantly near-saturating rpi2 cpu while doing effectively nothing last time I turned it on. (70%+ cpu time). This is why I'm thinking I'll wait for golang until I try again.

>Right now the protocol is relatively good

Couple questions:

- If I delete my server database, start anew, and join a room I used to be in, will I end up in a bad state, or are things more robust these days? I remember reading about it somewhere.

- Does the server _still_ solve a bunch of names and open hundreds of connections / server event interval or whatever it was called?
Well that's kind of truism. Good food, good education, good car, good house and so on, none of them have to be expensive, but more often than not they are.

Are you saying that conspiracy theories are all true?

> I'm not sacrificing truth to point out your mistake.

You are wasting 100% of your effort on arguing semantics instead of engaging with my actual argument, sounds like a tradeoff to me. And no, it's not a mistake, don't know where you got that idea from.
I mean, the article claims the first mention of it was in early 2011 on LW, so your timeline makes sense. Maybe it was on IRC or something else that you heard about it at all.
Python and Memcached: Efficient Caching in Distributed Applications
This echoes my experience during the mortgage crash so much it gave me flashbacks.

- Bank of America messes up my loan because the person doing my paperwork was a newbie. No biggie, right?

- Branch manager offers to fix the issue and prioritize it so that we can close in time.

- Branch manager is unable to fix it in time so offers to pay our closing costs and re-finance the loan afterwards.

- Branch manager leaves the company after our loan is completed.

- Don't qualify for re-fi because we owe more than the house is worth.

- Don't qualify for loan modification because we've never been late on our payments.

- Reported to FHA. Got in touch with local news station. Immediate response from BofA's Office of the President.

- Rep from Office of the President that was "assisting" quits 2 weeks later.

- Get another rep and they start a "forced" loan modification. Assign me another, lower rep and promise follow-up in 2 weeks.

- Repeat ad nauseum until I literally can't even and decide to foreclose because it's such a cluster.

Your last few sentences really strike a chord here. I totally feel for you.
I paid for some map updates for my older model of TomTom a year or two ago - I considered using a free alternative but I was about to go on a road trip and wanted to be sure I had the right maps for my device plus thought paying might be some guarantee of quality.

The "new" maps were out of date - road alterations which had happened 2 years previously in my home town weren't on there yet. We found various other places on our trip where it seemed the road layout had changed since the maps came out, too.

Maybe I did something wrong somehow but it wasn't a very good advert for paying for maps. I've never used OSM on a drive but it's very good for walking in my local area as it has pretty much every footpath/cycle path (unlike Google Maps, which is very road-based), so I'll try it next time.

As for that older TomTom, I replaced it with a newer model because the battery life had gone right down and the touchscreen was failing, but the new model touchscreen is also very unresponsive, it already needed constant charging even when it was brand new, and the interface and directions aren't as clear as the decade-old model. I won't buy TomTom again.

Oh come on, that post was very clearly made knowingly within that context.
Salting isn’t what I mean by random, I mean literally having the hash value have nothing to do with the item you’re hashing.

Either way, terminology is weird here, but it seems like in V8’s case the word “hashing” better describes what happens to the hash code when the hashtable algorithm decides what bucket to place the object in (likely a modulus operator or a bit shift), at which point the “hash code” isn’t a hash value at all but just a unique ID that’s a seed value for the real hash function... but again, terminology can be misleading.

Try working for TomTom for a few years. Then you'll have a different perspective about those accursed "personal navigation devices".

They didn't appreciate my proposal to develop the TomTomagotchi: a PND with a simulated personality that begs you to drive it all around town to various points of interest it desires to visit in order to satisfy its cravings and improve its mood.

Did anyone read the article? It’s going To be set up as an independent company without profit as the motive.

They know all their companies will earn more money if there is more money in everyone’s pockets. Look at how much some people are spending per year on healthcare. Someone in this thread mentioned $30k for his family in a year just for insurance. If he even saved a third of that, it’d end up being spent somewhere. A good economy benefits all those big companies. The losers in this are the healthcare companies.
It's actually almost always a post-hoc justification for scratching an itch.
It is one of those topics that crop up every now and then. What emerges from the picture is that few of the low skilled worker at the construction site where slaves in the way we picture slavery today with many in a social situation more akin to serfdom.

At what point slavery becomes serfdom is more a matter of semantic. Then again there were both actual slaves, i.e. prisoner and spoil of wars and skilled craftmen working at the decorations, detailing etc, because building a pyramid was not just the "moving rocks" parts.

Attempting to reduce something that complex to a single slave vs non slave structure is reductive at best, especially in a society with a caste system such as the Ancient Egyptian. Just think about the ideograms, those were written under the direction of the religious caste, even if indirectly.

Hacker Hostel 2018 – Hack in Jamaica, Trinidad, or St. Lucia This Summer
Hacker Hostel is a unique startup from
Jamaica with the goal of solving technical problems in the Caribbean with help from
companies like Google, Facebook, and Microsoft.

The programme’s goal is a hybrid of philanthropic efforts, providing job opportunities and tourism. Participants all have the opportunity to meet representatives from leading technology companies while gaining work experience and applying new technologies to solve real-world emerging market problems.

Hacker Hostel's four-week programme solves problems for Caribbean startups, NGOs, Government agencies and businesses who do not have the technical capacity to solve their own technical problems. Through our partner network, Hacker Hostel combines top graduates and employees, from the U.S, U.K., & Canadian. universities and companies, like Microsoft, Google, and Facebook, who then document and prototype the problems.

Local talent in each of these Caribbean countries is also working alongside the mentors and attendees throughout the program. When the prototypes are approved by the sponsor, the local talent is then employed to implement working solutions and provide support going forward.

CEO of Hacker Hostel, Akua Walters stated, “We believe the Caribbean will become the next great technology hub and we’re thankful to our regional partners such as the Government of Trinidad & Tobago, The Government of St. Lucia, The Musson group, Microsoft among many others who have donated over 100 hours of their knowledge equity. The exposure our participants receive have resulted in over 5 people gaining employment in our first year. Our top goal for 2018 is to further expand our hosting of Hacker Hostel in the Caribbean and offer more employment opportunities. People are encouraged to visit our website at http://www.hackerhostel.com.jm/ to find out where our next hosting will
be and register to participate.”

It’s useful for certain theoretical proofs in analytic math - or so I’ve heard. Not all math is well suited to be coded into reliable software.
Having recently received a reasonable fraction of a bitcoin, I am interested in what the optimal ways to cash out on it from a theoretical perspective are. Say I have some guess as to what chance it will have X value in Y years and have some quantified percentages of risk/security. How much do I sell now, how much should I hold on to "in case", etc? I feel like there is some mathematical advice here that I don't know. I feel like the best strategy should be something like "sell 50% every year" where 50% will be dependent on what I expect future performance to be.

Edit: and ironically, it's the inconvenience of selling it that has kept me from doing so yet! The opposite of the author's problem.
Reminds me of a controversial technique discovered in the TAS community. Start saving your savefile, then cut the power mid-write. Usually creates a savefile with a bad checksum, but with certain timing on certain games, can result in playable corrupt savefiles which can be used for a faster win.

One of the reasons this idea is so controversial is the TAS community always assumes games should be played frame by frame, but this technique would open sub-frame "gameplay" (timing when you cut the power with much higher precision)

Tony Blair stepped down under pressure from Gordon Brown with whom he'd already pre-arranged an exit and poor poll performance. Gordon Brown, who is his ideological brother, replaced him. Trying to characterize that as a deposal of Blair and everything he stood for is... oh, what's an appropriate phrase?

Ah yes. Intellectually dishonest.

Yes, it's true that not every policy Corbyn's 2017 manifesto had was unpopular with the PLP and it is possible to cherry pick many which they had no problem with. Their fundamental problem with it was not admitted to by the PLP but Blair did state "I wouldn't want Labour to win on his platform even if it was popular", maybe because he hates free school dinners. Or not. You tell me why he said it.

The rest of the stuff is more of an excuse to dig in to him. I don't think it's realistic to believe that members of the PLP who, on the one hand praise the success of the Chinese dictatorship at bringing people out of poverty, and simultaneously condemn Corbyn for saying the same of a Latin American democracy actually care about Venezuelans. They're grandstanding on a particular issue to try in order to try and open ideological rifts in the party. Ditto all that rubbish about Marxists and rabbles of trots.

>the party's poor performance in polls

The poor polling coincided with the PLP's constant attempts to undermine him and Labour's unpopularity peaked during the coup when they did everything they could to destroy him. The polling was entirely a self fulfilling prophecy on the part of the PLP.

They created the poor polling of the Labour party with the coup and he dragged them out of it with an unexpected strong performance in the election. It's amazing how well he can perform when knives are removed from his back isn't it?
It's not necessarily about corrupting the courts. It is about maintaining influence or outright control over police, prosecution, legislation or whatever body (very often a political body, as in The States) is responsible for investigating or prosecuting political offenses.

In failed rule of law states, it has often happened that former politicians were/are criminalized. This can make losing power, in practice, directly lead to losing life & freedom. This then becomes a mandate to maintain power by whatever means necessary.

It also opens the door to political purges of oponenets.

I'll take an example from the Middle East (my home). When Saddam lost power, he was hanged. Gadaffi was lynched. Mubarak was imprisoned, then released when his faction came back into power. This creative an imperative for Assad to maintain power in Syria. Losing power is a death warrant for him, and he is willing to kill even more brutally to preserve himself.

In Israel, Netanyahu is under criminal investigation. He has immunity from prosecution while in power, but not from investigation. This is very dangerous and many analysts (including US generals and spooks) are worried he will start a war in order to consolidate power. tricky stuff.

These are not rule of law states, and they do not have independant judiciaries. But the principle stand. This is why I found (for example) Trump's threats to Clinton so disturbing. If he had followed up, the entire american system would be in danger.

Realistically, the process in place is there for a reason. Small crimes (eg Clinton's emails or Trump's contact with Russia, if it doesn't turn out to be worse than reported thus far) are swept under a rug. Large crimes (Clinton's BJ?) should be investigated through some non-criminal (courts are OK, the US system is suboptimal here) system where life and freedom are not at stake, just power.

Courts cannot be subsidiaries of executive-legislative power (even in the states where it is explicitely forbidden executive & legislative are not really seperate) but the opposite also cannot be.

It is ugly the way it is. We should be doing better. But, there really are fundamental issues here with the stability of democracies at stake.
I'd be curious if you could find the source for that, and I mean legitimately curious - I'd be interested to see what kind of evidence that kind of a claim is based on. Egypt at least does have extensive written records, so that could be codified in a statute somewhere.

I'm sort of skeptical by default of archaeological claims that assert conclusions wider than what their findings directly show - too often it seems like they've gone in with a preconceived big theory that they are grabbing at straws to find support for.

I think what people feel sensitive about is the emphasis on slaves. It's like slaves are being retroactively disenfranchised. That probably irks people when they think in a modern framework.

Bringing the Sharing Economy to the Airwaves Will Boost Your Bandwidth
Objects in some programming languages (like JavaScript, but not like others such as Haskell) have an identity value. This is an abstract value. It's a theoretical thing. We pretend it's there but it's not like a usual value. It's not something you can actually see or calculate with. You can just compare them.

A hash function takes a value or a compound value and produces a simpler integer from it.

An identity hash function takes an identity value and produces a simpler integer from it.

Based on all these definitions, returning a random integer, as long as you store it and return it again the next time, is an identity hash function.

> you normally hash the id/content of the thing you want to store

That's what we're doing. You've said it yourself. We hash the id (identity) of the thing you want to store. You could call the identity the content of the object as well if you wanted to.

It's not about replacing the actual content on the object, because JavaScript maps are, by design and by definition (23.1.3.6, 7.2.10), explicitly identity maps. They don't want to consider the content of an object, except for this abstract identity content.

I'm not sure if you're arguing I'm mistaken, or the that the whole idea is wrong. But this is what many languages do and it's all very conventional terminology and practice.

You didn't read Martinez-Fuerte carefully, or the previous comments I linked to, which (amusingly) discuss Martinez-Fuerte in comparison to Almeida-Sanchez.

In short:

Martinez-Fuerte authorized stops within range of the border, but explicitly disallowed searches; what made the stop in Martinez-Fuerte lawful was that it wasn't a search. You can be stopped anywhere in the country with virtually no probable cause; it's what happens when a traffic cop pulls you over for a "bad lane change", or to check your insurance. When that happens, the police cannot then pop your trunk and rifle around in your glove compartment --- nor can they take and image your phone.
This is true for the most part. The majority of loops out there are still PID. Most mechanical systems are fast, simple and linearizable, and PID is robust and simple to implement. The control law is simple.

Advanced Control techniques like MPC are generally applied on complex plants such as chemical plants. In chemical plants, systems are slow but complex (highly multivariate with many interactions), so more complex optimal control techniques like MPC have a larger payoff. MPC has to solve an numerical optimization problem at every iteration, and requires more computational horsepower (not to mention prior mathematical modeling from step test data).

But even in chemical plants, the local loops are PID (actually, PI... D is rarely used). The MPC layer optimizes an objective function and sends setpoints to local PI loops to carry out control.
These companies collectively have hundreds of thousands of employees that cost many billions each year to insure. Large U.S. employers are what you call in the industry "self funded", meaning they collect premiums from their own funds + employee contributions into a big pool and pay out claims from this pool (i.e. they take on all the insurance risk). Any optimizations they can make to plan administration, healthcare utilization (i.e. incentivizing employees to choose less expensive forms of healthcare or get healthier), lower drug costs, lower administrative cost, etc. will save them many billions of dollars annually.

Saying this new venture is going to be free of profit-making is a bit like saying water is "sugar free." This is all about lowering their own cost of employing a massive workforce.
