When you encounter people who don't respect your judgement as much as they "should", I'd suggest it may be because "how well it scales" doesn't guarantee "appropriateness". In most real world situations, the specifics of the chosen stack are rather inconsequential - both MS and *nix stacks perform more than adequately. In my opinion, it is unwise to take the advice of zealots who refuse to acknowledge this reality.

So is that not an impressive solution - if Alice wants to move 100 USD to France and Bob wants to move 100 USD out of France (let's say both want to buy a new textbook) then one could envisage a peer to peer money transfer system.

A site allows bob and Alice to find each other, agree a shared amount to transfer, agree to which end point they will onwards transfers (hmmm this might be the breakdown point) and then record that in the block chain

I think oddly there is still an enormous amount of trust involved - trust that Alice will complete the final important step of giving the money to Bobs silver haired grandmother or whatever

The alternative is to have them formatted as paragraphs, but that makes it hard to group together. Hacker News doesn't really do single-spacing well, or any sort of formatting. I wish it had a real Markdown implementation, but, well, that's the cost of writing it in a language with no libraries.

So this is an interview question, apparently by a senior manager. The obvious reply should be: What do you mean by faster? Do u mean writing this code is faster? Reading this code is faster? Compilation is faster OR may be you mean execution is faster? In case you meant execution then could you please mention the kind of computer on which the execution will happen? By the way it seems that both the code will run forever and ever, you can't figure out who won a race until the race ends and here it seems the race is going on forever.
Interesting, they did a talk at Education City in Qatar and I had no idea about it? Very disappointed, and surprised they had talks with these kinds of experts on this talk (censorship avoidance is not looked kindly upon there).
Patent litigation and Patent Examiner's experience
For a long time synchronized clocks was the networking code's equivalent joke to Regular Expressions ("Now you've got two problems ...") That said, having implemented a 100ns accurate clock using the PPS on a $30 GPS module (Adafruit) and a Beaglebone Black (multiple) these days there are some interesting alternatives. It would be interesting if the Open Compute folks would specify a 1PPS GPIO input as part of the spec, you could easily deliver rack level 1PPS accurate signals throughout the data center pretty cost effectively (a few wires, a transmitter, a TDR tool. Not that it will ever be a 'solved' problem but it certainly makes some transactional protocols safer.

You can buy GPS receivers and install antennas. Those are pretty good but expensive.

For S2, it can be configured to never jump. Instead you can just the time manually (run the equivalent of 'ntpdate <server>') at boot perhaps. Then don't start your software until ntp has been synchronized. Then maintain a watchdog that will alert you if you drop to a too low of a stratum.

Don't have an answer for S4 and S5. But I have heard that chrony is a good replacement for ntp (same network protocol but different discipline, faster conversion).

http://chrony.tuxfamily.org/

For a whole new other thing there is PTP (https://en.wikipedia.org/wiki/Precision_Time_Protocol). This is good if you want to synchronize machines to each other to withing a couple of hundred micros (maybe more with special network cards and switches).
What I do is I generate an inhouse CA for uses like these and hardcode its certificate into the clients: the key used by the API server can then be changed whenever necessary, just as if it were signed by a commercial CA.

Ask HN: Is home irrigation a good target market?
I'm talking about sprinkler systems for lawns / gardens. ASP is substantial, overall number of units is large, upgrade cycle is... well that could be tricky. You don't want to target only new construction.

I'm not sure how large the irrigation market is, but in general if you can save people money by buying your product, and even save the environment while you're at it, it's a good start.

I can think of all sorts of tweaks you would want in a decent irrigation system. All the way from system design, coverage, level of control and adjustments, to usage stats, performance tracking, etc.

Maybe I'm just a little over-sensitive to making sure the system is operating at its peak, but there's a decent amount of actual work involved in maintaining these systems.

There's a lot I think you could do with just some Bluetooth LE flow meters that can be attached in-line at various points. Maybe next step is building them into the valves. Bonus points if they are self powered by the water flow, but probably totally unnecessary. Ideally no swapping batteries.

Is anyone targeting the residential market here? Is this Google Nest's next target market?
Probably not. The power switch was at the back because that was were the power supply was.

IBM didn't put much thought into safety. You could blow up the early IBM's if you turned on the monitor (screen) before the CPU box.
I've used PTP with special timestamping hardware (network cards) and could synchronize machines on a LAN pretty well. Now that doesn't guarantee global sync just sync between machines.

GPS NTP server can be obtained for as low as $600 or so. So those are becoming not as exotic now.
> Although the standard does state that Strings with textual data are supposed to be UTF-16.

No, it doesn't. It states that they're UTF-16 code units, a term defined in Unicode (see D77; essentially an unsigned 16-bit integer), which is not the same as UTF-16. A sequence of 16-bit code units can therefore include lone surrogates, which something encoded in UTF-16 could not.

As soon as you have any kind of highly-distributed system, accurate clocks are usually very important. When events can start on one machine, and end on another, it's important to have some kind of consistency (knowing that one event occurred before another). Probably the most famous paper on this is Lamport's "Time, clocks, and the ordering of events in a distributed system" - http://dl.acm.org/citation.cfm?id=359563.

But to give a practical example. On something like facebook, if you receive two comments on a post within a millisecond, how do you determine the order that they appear in the list? Each request may hit a different datacentre in the world, yet somehow the machines determine the ordering, and every request sees that ordering from then on. You can't just have a single server, because that couldn't handle the load for the entire world. These kinds of things require very strict temporal ordering, which is why time is such an important thing. This leads to the CAP theorem, and distributed systems in general.

I've seen quotes that suggest the missiles cost between 20 and 100,000 dollars. How is it suitanable to continue using the Iron Dome at such a high cost?
Being a pilot, this technology reminds me of "Mode S" transponder systems transmitting to SSR and ADB-S to identify a civil aircraft by its call-sign and exchanging various other information with the recipient (e.g., to avoid collision). Here's the ICAO specs http://www.icao.int/isbn/Lists/Publications/DispForm.aspx?ID...
The only way the Iron Dome works is as a propaganda tool for Israel.
There's no evidence to speak of in the article--just calculations speculating that the success rate should be low. At best, it calls for Israel to produce evidence that the system is indeed working.
I've heard about it, and it does have an interesting feature set, but I've also heard negatives.

The comparison with git is very shallow, seemingly based on misunderstandings of how git works.

On branches they describe the Linus/Linux workflow, ignoring the fact that a more traditional workflow can also be supported by git. In fact "git flow" is a recommended workflow, and it's pretty much exactly what Fossil does (only with more flexible merging options).

Sharding vs. Replication turns out to be a matter of defaults; otherwise there's no material difference.

The web interface is cool, but I use GUI tools locally that are nicer and faster than any web interface could possibly be. Speaking of, there are a plethora of GUI tools available, free and for pay, for GIT.

Rebase is one of my favorite Git features; they claim it's a feature that it doesn't exist in Fossil.

Complexity is a good point, and git has famously bad command-line UI. I'm sure Fossil does a better job there; Mercurial and Bazaar certainly do. But git has the features I need, which isn't true of Mercurial or Bazaar, and git has a user base of a sufficient size (compared to Fossil) that I don't worry that I'll hit some corner case bug and lose data.

Zed Shaw used to be a major fan of Fossil, for instance, but then he lost a repo irretrievably and swore off using it. His old site with essays seems to be down, or I'd link his posting about it. Having everything in an SQLite database means that SQLite usually will be safe, but if something does go wrong, well, you're screwed.
The electric drive motor is about the size of a watermelon and weighs ~70lbs. Its easier to pull it and swap in a new one than to tear it down on-site.
Interesting analysis. If the Iron Dome is mere security theater then it makes it makes sense that the IDF won't simply sit back and let Hamas fire away until they run out of rockets. Enough property damage may make Israelis' behind the Iron Dome realize that it's only the shelters that offer real safety.

I'm curious about Hamas' choice in rockets though. Would larger rockets present as easier targets for the Iron Dome? If so, then the Iron Dome does indeed serve an important purpose by limiting Hamas to rockets small enough to be harmless to shelters. If not, then why would Hamas not use rockets large enough to penetrate a shelter?

Finally, let's assume the ineffectiveness of the Iron Dome was commonly known. Given the sharp increase in IDF casualties after the ground invasion started, would it still have made sense to invade if there was no fear that Israelis might lose confidence in the Iron Dome?

Its funny you mention Baltimore. I researched the issue extensively because I'm moving there in a month.

Baltimore's agreement with Comcast is non-exclusive for television service: http://articles.baltimoresun.com/2004-09-21/news/0409210094_....

The reason Verizon doesn't offer television service in Baltimore is because it doesn't have a cable TV franchise from the city. The reason it doesn't have one is not because Comcast's contract is exclusive, but because the city won't give Verizon one unless they agree to build out FiOS to the whole city. Verizon won't do that because it makes no financial sense to build fiber everywhere in a city where a quarter of the population is at or below the poverty line. It dramatically increases their cost per actual subscriber, which is already iffy for FiOS to begin with. Verizon hsd built internet service only to a few high end communities, something that doesn't require a city-wide franchise.

Google won't enter Baltimore for the same reason Verizon won't. Google does not agree to build out requirements for Google Fiber. They demand the right to only build fiber in neighborhoods where enough people sign up to justify it: http://www.oregonlive.com/silicon-forest/index.ssf/2014/05/g....
Better to step down to 12v at one high-efficiency DC-DC converter than try to build accessories that can handle hundreds of volts.
In the USA, a human life is typically valued (for risk analysis etc) at $5M or so.

Break even happens if a single missile would prevent a death 2% of the time. That excludes the psychological costs, property damage, and other possible negative results.
>there's no reason large companies couldn't open BTC accounts at Chase or Wells Fargo and accept them directly

It is important to consider that Hamas doesn't have much "choice" in their missiles. They just use whatever they can get their hands on.

These are not restrictions. At this point you DO NOT own a game yet, it is still packaged like an unopened box wrapped in plastic wrap. It is essentially the same as if you buy a new phone or dvd and without doing anything to the box simply resell it to a different person.

Toying with gifts the way you mention may get you banned, there are certain restrictions as well which may result in you not being able to launch a game since you are not in the specified region (ip check) and vpn/proxy use is against ToS so it is a gray area, you keep doing it and you get banned eventually.

When it comes to TF2 items each player has a choice whether he invests time or money to get the resources to craft items, i'm not an expert on this but since resources are made literally out of thin air there is mostly supply/demand.

Getting everything on a laptop supported is definitely hard, so any help you can give is appreciated.

When it is supported, there are different outcomes. The individual board pages on the wiki can offer more details. The X60 is especially well supported because of a combination of factors:

1. Lenovo was actually pretty helpful

2. Lots of coreboot hackers have worked on the machine for years

3. Lots of other linux hackers have also worked on various parts (which improves the support for all the devices)

So without doing any research, my understanding is that the X200s and to a lesser degree the X230 cannot achieve that level of support, mostly because it would take the coincidence of all that work coming together. But it's not all bad: the Chromebooks are getting that work done by a group of paid engineers, and there is a recent addition to the supported laptops (not fully open, but close; not amazing hardware, but decent) - the HP m6-1035dx.

I got an HP m6-1035dx on ebay, and my experience is that everything works fine. I suggest throwing away the mini PCIe wireless card it comes with and putting in a better one, but I haven't brought it up on the coreboot mailing lists because it's not really coreboot's fault. HP just built a cheap laptop and so it has a junk wifi card.

Hopefully that helps? Cheers!
I'm not a fan of the way that argument was phrased, but the obvious difference is the physical difference between how a physical object is "stolen" and how a digital work is "stolen." It just comes down to property rights, which are subjective and change over time. Under my own subjective impression of property rights, someone breaking into my house and taking a sculpture I made is a violation of my rights, but if I sell a CD to someone and they give away a copy of it, I don't feel like there was a violation.
First, it sounds like Tesla service is pretty great. All that work at $0 cost, done in 1.5 days, is pretty incredible. Good maintenance should bring a positive ROI.

Yes, there's a downside, which is out-of-warranty cost, and ultimately resale value. It's both a science experience we are funding here, and a public company. I would love to have seen some hard numbers from the stated financials about warranty costs, and expected future warranty costs.

I think it's a good question to ask -- is the longer term service cost of the car understood? Maybe we're just starting to get to that point, but I'm not sure the data is really out there. I do expect of any company that Tesla would be the best at predicting their long-term performance and costs.

It's one thing if the car isn't perfect, it's another if it becomes a maintenance nightmare. That could happen only outside of warranty, and not even directly impact their expenses, but it ultimately does impact sales. I would expect if there's an issue that Musk has discussed it at length already. This clearly isn't new.

I don't like the scaremongering about the cost of this repair. Did they even ask Tesla how much the repair would cost, and they refused to answer? It certainly doesn't say that they even asked the cost. I doubt it would matter, but I'm sure there's a law that they have to disclose the retail cost of the repair.

I know car reviews rarely quote the CEO, but for this specific issue of drive train, I think it's worth getting a quote from the company in the article.

Comparative Analysis on Modeling and Implementing with MVC Architecture
I have a co-worker who has a 4 day a week - 112 mile commute into work (Sacramento into Redwood City) - by avoiding rush hour he does it in a little over 2 hours each way, he puts almost 50,000 miles/year onto his vehicle. I thought that was the most insane soul crushing thing I had ever heard of.
Most of the car's internal electronics (lights, airbags, ignition, touchscreen, instrument cluster etc.) are based on traditional components that require a 12V connection. The 12V battery in the Model S also powers the high voltage contacts that transmit power from the main battery to the motor.
Ask just about anybody with a 1-hour (freeway) commute. For example, anybody who lives in SF and commutes by car to Cupertino.
From the first sentence:

> Over in Atlanta, not too far from Chattanooga, the public sewer system has major sections dating back to the reconstruction after the civil war, and dumps untreated sewage into the Chattahoochee after a big rain overflows the system.

Wow. Just wow. You do know that Atlanta privatized its water, right? The private company, United Water, failed to deliver on it's contract. The city took over water duties again after finding fraudulent billing and lower water quality delivered by United Water. Since the city took over in 2004, they've reduced sewage overflows by 97-99%.

That's a really terrible example to use for your argument.
