> I mean is electricity free in the US?

No, but it's a lot cheaper than gasoline.

The average cost of a kilowatt-hour is something like $0.11-$0.12 in the US (some places are much higher, some are lower).

The highest-capacity model with an estimated 300-mile range holds 85kWh. Tesla claims >90% charging efficiency, but let's just say 95kWh to charge.

95kwh * $0.12 = ~$11.40 per 300 miles.

Right now, a gallon of regular gasoline in the US averages $3.601.

300 / 50mpg = 6 * 3.6 = $21.60

300 / 40mpg = 7.5 * 3.6 = $27.00

300 / 30mpg = 10 * 3.6 = $36.00

300 / 20mpg = 15 * 3.6 = $54.00

300 / 10mpg = 30 * 3.6 = $108.00

As a point of troubling comparison, the Model S gets compared to a BMW M5 a lot, which apparently has a 16mpg/24mpg city/highway rating.

Another useful comparison is to a basic Prius, which has a 51/48 rating, but is substantially smaller, lighter, and less performant than the Model S and M5, but the Model S still beats it by a large margin.

When Tesla gets around to a Prius-like EV, the numbers are going to be even more ridiculous. The "fuel cost" of commuter EVs will simply be noise in the typical family budget.
I always install sl because it helps me. If I'm frustrated from typing too quickly/angrily to even get "ls" right, the little train breaks me out of my fugue state and I have to laugh and shout "choo choo!" in the office :D
Yeah, so why not just go after those extreme cases rather than broadly and generally defunding public education and ruining teachers' old age?
If you actually read the article simple questions like this will be answered.

Slight correction, ISP or Corporation can run a HTTPS proxy. In effect, your 'HTTPS' connection is to the IPS/Corporate proxy only.
Why do state employees enjoy the privilege of pensions and free healthcare? Why can't we force them into the real world of shitty insurance plans, financial responsibility for their own retirement supplemented by social security checks, you know, the life style that private sector employees are "enjoying"?

Why not broadly improve compensation packages in the private sector to keep up with productivity, which would increase the tax base and allow each individual's tax burden to take a smaller share of their income?

Well gather up all your money + several hundred thousand more and burn it. All cause you didn't read the EULA of your scanner, the patents in question, or have a clue about US law.
This reminds me of an obvious-yet-not-that-obvious trick when it comes to quoting for new features using an unknown technology:

Be honest, ask to sacrifice a couple of hours to throw at a proof-of-concept, and then you should have a better idea of how long the full feature will take to implement.
We have a similar problem in the UK - some public sector administrators seem to make vast amounts of money for jobs that seem secure and rather undemanding to me.

What I find particularly annoying is that people at the "sharp end" of the state (rather than administrators) often seem poorely paid for the responsibilities they have. A recent Royal Navy recruitment advert pointed out that you can make up to £95K serving on a submarine - to which my reaction was "that's all the commander of a UK Trident submarine makes?".

NB In the case of UK Trident submarine commanders this seems particularly bad as they (and their crews) have far more freedom than people in equivalent positions in other navies. As far as I know, only the UK Trident submarines have the power to launch without any authorization from the PM or anyone else [there were good reasons for this, at least during the Cold War]. So we really trust these men and women.
I do not believe Yahoo Mail's assertion here. I have a Y! Mail account (which I do check once a week) and almost 80% of mails are spam. So they are not doing a good job at it (vs. GMail which is the other email provider I use) and thus their metrics here look skewed to me.
Given the nature of the hobby, I get the feeling that few people have paid for it. That said, the older IDA Pro 5.0 has been released as freeware: https://www.hex-rays.com/products/ida/support/download_freew...

I winced at the last sentence -- "You’re not a teenager leaving your homework until the last minute. Professionals go hard early."

I'm a graduate student who still leaves homework for the last moment sometimes. This mantra of going hard early can also be applied to a few of my assignments and academic projects.
Well, but there IS something to be said for letting the idea simmer. Isn't that where ideas come from?

The problem with the US government is a tragedy of the commons (ie the district-by-district and state-by-state pork barrelling).

The original intent of the Founding Fathers and the view held by libertarians and traditional conservatives (rather than the neoconservatives and religious conservatives that dominate today) is one of limited Federal government for specifically this reason. A minimal government is one not worth buying. A big and intrusive government is one totally worth buying.

You were doing so well until you veered off into right-wing proprietarian ideology!

If the US government is subject to a Tragedy of the Commons due to its mode of subdivision, then eliminate the subdivision. Amend the Constitution to shift to a Mixed-Member Proportional parliamentary system.

I see no reason not to solve the engineering problem rather than declaring that having the government do more than enforce private-property titles is immoral.
Another data point. A dog in the office destroyed my productivity and shot my stress up through the roof for the best part of a year. Loud animal, barking all the time.

Dogs in the office aren't always a good thing and are about as far from a professional working environment as you can get.
Even normal selection "stuck" funnily; I could tell there was something between the clone and the rest of it. Again, possible to mitigate I'm sure.
Under UK law, if you receive money in error, you have to have a good faith belief that the money is actually yours. To claim that you thought that the bank was deliberately choosing to give you more money than you asked for (rather than it simply being an error) stretches credulity a little too much.

See, for example, a family who were jailed for exactly this:

I'm confused as to how what you're saying or what parent is saying would work. The trusted CAs live on your computer, and should not be susceptible to tampering by your ISP. And how can your ISP or corporate network set up an HTTPS proxy like you're suggesting without triggering a warning to the user that they are not connecting to the SSL certificate's specified domain?

Is there something about SSL/TLS that I'm fundamentally misunderstanding?
In regards to getting outside, don't do it regardless of your mood, do it because of it. Getting depression under control seems to be helped with a regular stint of outside. I don't know why, but give me a tool, preferably power driven, and I'm sorted. I might be mentally tired but Im rested and relaxed and will sleep.
I don't believe you actually have to use a thing for the thing to be in violation of patent. Just having created the thing (connecting network to scanner with 1 click scan to email) is in violation of patent.
yeah, I haven't had any problems using it to run various programs completely sandboxed.
I always paste my things inside Chrome's Omnibar. It trims surrounding spaces and associated style.
I agree completely. There are also some great small communities that aren't socialist dystopias. So, yes, I would like to be able to take my pick.

As long as the power of Chicago's socialists is limited to Chicago, you can escape the dystopia that emerges from their absurd policies by escaping their jurisdiction. But if all (US) power can be centralized in Washington, then the same people who produced socialist dystopias in Detroit, Chicago, or San Francisco, will impose them on everyone in the country. I will no longer be able to take my pick by leaving their jurisdiction, and that's what they define as "progress."

It's interesting how different peoples experiences of that are. I have an "ancient" Yahoo Mail address that I don't use much but that receive a massive amount of Spam, and pretty much nothing gets through.
I believe ISPs can not have a transparent HTTPS proxy without the "invalid certificate" browser warning.

When SMS first exploded in popularity back in the day a friend of mine worked at BT (British Telecom) and pointed out that the entire network's SMS traffic was handled by 3 mid-range sun sparc servers.

Since SMS was originally designed to use management channels it was already built into the general infrastructure, they just needed to up the server count to 3.

SMS was (and maybe still is?) almost pure profit for at least BT and I imagine other carriers.
git staged

alias for

git log remotes/trunk~4..HEAD --pretty=format:"%C(yellow)%h%C(white) %ad %aN%x09%d%x09%s" --date=short | awk -F'\t' '{gsub(/[, ]/,"",$2);gsub(/HEAD/, "\033[1;36mH\033[00m",$2);gsub(/master/, "\033[1;32mm\033[00m",$2);gsub(/trunk/, "\033[1;31mt\033[00m",$2);print $1 "\t" gensub(/([\(\)])/, "\033[0;33m\\1\033[00m","g",$2) $3}' | less -eiFRXS

Shows condensed log of unpushed changes with colours and truncates HEAD/master/remote to initial letter.

Add to config with:

git config alias.staged '!git log remotes/trunk~4..HEAD --date=short --pretty=format:"%C(yellow)%h%C(white) %ad %aN%x09%d%x09%s" | awk -F"\t" "{gsub(/[, ]/,\"\",\$2);gsub(/HEAD/, \"\033[1;36mH\033[00m\",\$2);gsub(/master/, \"\033[1;32mm\033[00m\",\$2);gsub(/trunk/, \"\033[1;31mt\033[00m\",\$2);print \$1 \"\t\" gensub(/([\(\)])/, \"\033[0;33m\\\\\1\033[00m\",\"g\",\$2) \$3}"'

Although I've changed it a bit since I worked out the above. Here's what I currently have in my config file:

staged = "!sh -c 'git log ${1-remotes/trunk~4..HEAD} --pretty=format:\"%C(yellow)%h%C(white) %ad %aN%x09%d%x09%s\" --date=short $2 | awk -F\"\\t\" \"{gsub(/[, ]/,\\\"\\\",\\$2);gsub(/HEAD/, \\\"\\033[1;36mH\\033[00m\\\",\\$2);gsub(/master/, \\\"\\033[1;32mm\\033[00m\\\",\\$2);gsub(/trunk/, \\\"\\033[1;31mt\\033[00m\\\",\\$2);gsub(/$USERNAME/,\\\"\\033[0;33m$USERNAME\\033[00m\\\",\\$1);print \\$1 \\\"\\t\\\" gensub(/([\\(\\)])/, \\\"\\033[0;33m\\\\\\\\\\1\\033[00m\\\",\\\"g\\\",\\$2) \\$3}\" | less -eiFRX' -"

Perhaps more importantly, getting feedback early on your progress is incredibly important. These curves are all in 2 dimensional space, but you could very well be flying off into oblivion and not to your intended destination.

Check in with mission control (customers / clients) regularly to make sure you're on the right path.
Looks neat. :)

It would be pretty nice (if I may suggest that ;)), if you added add branch support so the patches are saved into a refactoring branch or maybe individual branches?

Yahoo Mail has been really slow these past weeks. Like in "worse it has ever been"

So much I'm considering alternatives (and yes, I use gmail, yahoo is for 'second nature' emails, I use a 3 tiered approach, gmail for the serious/can't miss stuff, yahoo for important but may be subject to annoyances and another one for a throwaway email for non-important stuff signup)

I spent a lot of time with the elderly as a kid due to my community structure. Somewhere into becoming a teenager your interests change and playing checkers isn't interesting anymore but I still consider those who are alive as good friends and still visit when I can. I have often grown angry seeing the modern community detach the children from the aged, as doesn't it seem that we developed as a human society exactly with the help of our elders to take care of children, as the youthful were gathering/hunting/building? Some of the most functional families I know live closely with the grandparents who are secondary caretakers. Of course a time comes when one's age doesn't allow you to chase 2 year olds, and that's where I don't know how modern society can 'resolve' this without care facilities as we're not willing to expand our family sizes, large families being who traditionally cared for the elderly.

No real quality control from outside (How many administrators aren't former teachers?) and really, really high switching costs. If you want to switch schools you can move house or pay for the government schools through taxes and private school in fees.

Not that I think the evidence suggests there's much easy improvement in teaching quality but parochial/charter schools suggest you can do it for a lot cheaper.

Ask HN: What happened to your first few projects?
I've worked on several side projects over the last year or so, and I keep seeing ideas that're practically the same as those I'm working on having been fully implemented a few weeks after I've started. I'm not losing heart, and I'm taking this as a positive sign that I'm going in the right direction (albeit a little too slowly) - but it's made me interested in how common this is, especially among people who have many successful side projects a few years on.

How did your first few projects fail (if they did), and do projects still fail for the reasons I described above?

Implementing a "free market in local governments" has the massive negative externality of entirely destroying people's capacity to build roots and communities by staying in one place, and effectively turns the population into permanent ideological/lifestyle/economic migrants.

Romanian software and hardware developers, challenged at Raspberry Hack
Hackathon.ro, a community which gathers the Romanian programmers through regular hackathons held in Bucharest, announces a new event dedicated to technology enthusiasts. They are invited to compete at Raspberry Hack, a 24-hour marathon of hardware and software development on the smallest computer in the world, Raspberry Pi. The competition will take place on April 20-21 in Bucharest and will include prizes totalising 3,500 Euros.
Participants will develop hardware and software projects, within whatever theme they choose. The only condition is to use a Raspberry Pi for developing their project.
Raspberry Hack is the third competition in a series of events organised by Hackathon.ro to stimulate and support the activity of the main communities of programmers and hardware developers in Romania. The first hackathon took place in June 2012 and was dedicated to all open source fans. In October 2012, a new event took place. Over 200 programmers competed at Hackover, the second edition, in order to develop Mobile, Cloud Computing, Web Dev aplications. The value of the prizes awarded within these competitions has amounted to over 5,500 Euro until now.
The Hackathon.ro community was set up aiming to bring together the programmer communities in Romania, to stimulate the communication and cooperation between them and to encourage programmers to make the most of their creativity and skills. Software competition will be organised by Hackathon.ro at least two times a year.
Besides hackathons, the community intends to run other activities dedicated to programming and technology enthusiasts, such as workshops and trainings or start ups for great ideas.
You can find more details on http://www.hackathon.ro/en and on facebook.com/hackathon.ro
