Really? I live in SF, with a car that I haven't touched in over a year. I mean that literally. Not for grocery runs, not for weekend trips, not for visits to friends' houses, not for drives to work. It sits in my garage, collecting dust.

For groceries, there's a Safeway two blocks from my place (and also Amazon Fresh or Google Express). For anything else, there's UberX, Lyft, bike, Caltrain, and BART. (MUNI is, well, ostensibly an option, but I'll leave it be and maintain my uneasy peace with its existence.)

There's no question that NYC has a much better, more extensive, and more connected subway system. No question whatsoever. But SF's isn't bad at all.

Granted, I am an LA native, so I am predisposed to think of the mere presence of some form of public transportation as magical.
You could also use this to paint over graffiti and just paint in general.

That's really interesting to hear (I live in Vancouver too). I think it maybe also speaks to our North American culture of drive to work, stay at work, drive to home, stay at home... though I've heard that Vancouver is quite decent (compared to other North American cities) for having a downtown with actual people living there... similar to NY.
It may already be too late but if MM is listening... (she must be on Hacker News, right?)

Step1: Fix the authenticating and POP/SMTP email servers NOW, their performance has sucked for close to a year. Read the comments to the article and every fifth one is complaining about email issues. Fix the security, Yahoo emails get hacked way too easily. I once opened a new Yahoo account and before I had even used the account it already had spam waiting for me.

Step2: Drop the zooming cars and flying coke cans on the home page -- have some respect for your home page, don't whore it out to the advertisers. Yahoo was my first home page and I miss it but when they started this crap I left immediately. Revamp the home page as it is too busy and get rid of the endless scroll of link-bait infotainment articles.

Step3: Your customers have spoken, and continue to be ignored -- they hate the webmail interface. Fix it or users will continue to move on.

Step4: Stand up to the NSA and the govt and make it a clear Yahoo policy to do so. We have a constitutional right to stop dragnet surveillance, don't cave in to the pressure. Given the situation you are now a political leader not just a CEO, if you can't handle the heat then resign. You can also make it a competitive issue, and state in your TOS that Yahoo won't read your emails (unlike Google) nor turn them over to the govt without a warrant.

Step5: (Here is the hard part) Come up with a grand, long term strategy (and financial plan) that will allow Yahoo to compete with Google, MS, FB, et. al. Good Luck, I think you can do it.

I did just that when I switched my server from ESXi (which used the same formats). For me, the vmware2libvirt command from Ubuntu's virt-goodies package did the trick.

Where did you get the footage of Epic Citadel used in the talk?

http://unrealengine.com/html5 seems to have been purged from the internet (possibly due to this year's UE4 announcements?) and I can't find any mirrors anywhere.

Slow, dirty, delays/missing busses, infrequent service where I live, did I mention slow?

I ride my bike as my primary way of getting around. It's way faster than taking the bus (MUNI average speed is something like 8 mph) and I can leave work after 7:30pm (the time of the last convenient bus).

Can someone briefly explain for those of us who are electronically challenged what the purpose of diodes in series is (D1 and D2)?

Googling on "diodes in series", I found some discussion about how you can do this if you need a reverse breakdown voltage that is higher than that of one diode, but aren't D1 and D2 always forward biased in this circuit?
What is physically stopping us from actually seeing this planet with visible light? Is it that we can't build a big enough telescope?

This looks great but given Facebook has entered geo social space with today's announcement, it may be difficult to get people to install this. It may help to think about what use case can this serve that Facebooks functionality can not.
Seattle has started experimenting with "Parklets[1]" recently. The city gives up the right of way, and the businesses that sponsor them pay to build them, but can't restrict it or turn it into an extension of their space. It's an interesting notion.

It's quite different from "real world stealing". For a hacker, he only steals information and sells it. The actual money is siphoned out further down the chain by the people that buy stolen cc numbers and actually milk them...

Most of these "hackers" are just stupid kids that think along the lines of "hey, I just stole these bits of data from there and then sold them to this other guy for profit". Some even do it simply for the "high", as an antidote for depression or other mental issues, they could probably make even more money by simply finding a decent job that matched their skills set.

These kids are 99% harmless to society because they would never commit any violent crimes like an armed robbery or even a purely financial crime that would involve directly stealing from someone they can identify. Now, put them in jail for XX years, maybe even parole them and force them to work for a lowest payed wage for gov agency ABC (cough, helping it spy on its own citizens, without the risk of "crying wolf" like ES did, cough) to keep their "conditional freedom" (though this probably only happens for the most skilled of them), and at the end of it you will have transformed them into pissed off anti-social criminals that are ripe to engage in real violent criminal activities or ripe for recruitment by teorist cells...

From society's point of view, this is like smoking harder in order to cure your lung cancer...
I think this is bad, not because I don't like open source other things, but the patenting and commercialization of genes is something that we cannot permit. Establishing the difference between regular seeds and open source seeds is a step in the wrong direction, as there should never be a time that that distinction is necessary.
I've gotten several interviews through them.

I believe that an actual human matches up job descriptions and resumes there, and you get an email every time your resume gets matched to a job. You're then given a chance to allow or deny the company to receive your contact info.

The experience felt like something halfway between a traditional recruiting agency, and a job board like Monster. You don't have a recruiter in your hair trying to push jobs on you, but you don't have the option of browsing all available positions at your leisure, either.

They're pretty good at filtering out the noise (they've never pinged me over a job that was an obviously bad match, unlike some recruiters I could name) but I'm left wondering how much signal gets filtered out as well. Getting bites for anything other than web development can be tricky.
"In her latest move, Mayer is now culling the board. Yahoo has announced that John Hayes, EVP and CMO of American Express and Peter Liguori, CEO of Tribune Company will be leaving the board. This now only leaves five: CEO Mayer, Chairman Maynard Webb, retired E&Y partner Sue James, former IAC CFO Thomas IcInerney as well as tech entrepreneur Max Levchin."

I thought that in a public company, the board of directors is elected by the shareholders and the CEO reports to the board of directors. So how can the CEO arbitrarily remove members of the board? (Yahoo board members own a minuscule percentage of the company's stock; most of it is owned by institutional investors and mutual funds.[1]) Could someone who understands corporate governance better than I do please explain how this could happen?

Hi-- Rufus Jones. Pleased to make your acquaintance. I live outside of Germany-- in fact, I live outside of Boston. There was a 3-year period when you couldn't pick up a computer magazine without finding a 1-page or 2-page spread on 1&1 Media, which is why they have 13 million accounts.

I have mine because they're less annoying than MS, Yahoo or Google, and I really don't need more for LivingSocial or Groupon,
Interestingly, I had the opposite reaction. I plan on running node.js applications on Linode, and as node cannot automatically take advantage of multiple cores (and even manually the support is experimental), the announcement of vertically scaled but horizontally contracted CPU cores was very exciting to me.

I think the OP may have been referring to the massive expected price declines in the storage market. Price cuts like this:

Dropbox would ultimately have to start matching them & then slowly starts a downward spiral. However, if they move into the applications layer, the pricing pressure is less intense.
Gliese 581g is huge. Its mass is 3-4 times that of Earth. The newly discovered planet is much closer to the size of Earth, which is what the headline is all about. (Of course, mass and radius variations in this range have little to do with habitability, since both planets probably have enough gravity to hold onto an atmosphere.)

Can someone (who is more familiar than me on this topic) comment on whether this is a by-product of Xorg running with root privileges.

The systemd-logind work on Fedora [1] is attempting to run Xorg without root rights (and Wayland/Weston[2] in the future) and I'm wondering if that is a much more effective fix than all this sandboxing ?

I use Treehouse for learning web dev and they have a course on business fundamentals e.g. what type of company to incorporate, accounting fundamentals.

I think that Synapse already provides a plugin architecture. I t should be trivial to use the Consul HTTP API as a Synapse plugin. All this does is bridge the information Consul has and setup an HAProxy instance locally. If you want to go that route, should be pretty simple!
Kind of funny that people in the embedded area use C, which has a very weak type system and the result of using C is usually unsafe (no matter how programmers try) - even though its supposed to be compiled with static type checking.

> "It takes a macro to write a decent loop?"

That's the usual way to introduce a LOOP. As most Lisp implementations are written in Lisp, most syntactic constructs are macros anyway - whether they are at the language or the user level. For many Lisp systems there is really no distinction between both.

> Dropping into a debugger is not an acceptable bug-handling strategy in my world.

For embedded programming Lisp can have a lot of problems:

* lack of compile time safety

* the need for Garbage Collection

* no low-level machine types

* more...

Since the nature of 'embedded' is changing, some of that might no longer be such a big problem. In some areas 'embedded' systems are suddenly actually full-blown connected computers.
Paris (55,000/sq mi) is twice as dense as New York City (27,778.7/sq mi) (numbers from Wikipedia). It's one of the densest cities in the Western world.

Edit: though I suppose if you consider Manhattan to be "New York" then that is more dense (70,825.6/sq mi) than Paris.
Marginally relevant - are ARM Chromebooks any good for development? I've been considering getting a Samsung Chromebook 2 when it comes out, but I'm concerned that important software won't be available for ARM.

Anyone running crouton on an ARM Chromebook care to comment?
Not everything is follwing a (func arg1 arg2) pattern.

For example a LET binding is following a (LET ((var1 binding1) (var2 binding2)) body) pattern.
Ask HN: Completed JS CodeCademy but still struggling.  Other resources?
I just recently finished CodeCademy's JavaScript track. I'm assuming this is a small % of the knowledge really needed to be able to actually build shit. I went on CoderByte (http://coderbyte.com) and tried some of their "Easy" challenges and I'm struggling with some of the basic ones because it is stuff that was not taught on CodeCademy. The 2nd question was to write code to return the factorial of a number. Is this really basic shit, or did I just run into a weird question that is not very common in real world programming? I haven't taken higher level math in probably 15 years so I was concerned about this going into this process of learning JS but numerous people told me it wasn't that important. Are there other resources I should be learning from? What do you recommend to improve in the early stages? I'm trying to learn enough to get into a program like Hack Reactor.
I once read a book called Rare Earth;
http://www.amazon.com/Rare-Earth-Complex-Uncommon-Universe/d...

and the authors argued that the Earth has many unique circumstance necessary for the development of intelligent animal life that such life is probably exceedingly rare in the universe. The Earth/Moon and its stabilizing effect on the orbit, Jupiter the gas giant that protects the inner planets from asteroids and the development of an oxygen atmosphere, etc. and much more.
I don't know how much Rich Hickey used Racket, but he used Common Lisp for several years and wrote some complex libaries for it. There is also a sketch of Clojure early on written in Common Lisp.

It's been kind of fun watching JS developers reinventing good chunks of computer science and operating systems research while developing node.

This talk has convinced me that their next step will be attempting to reinvent computer engineering itself.

You clone credit card (can be done with $10 worth of equipment), go to the store and buy something expensive. Sell it on craigslist or (if you are brazen) return for refund.

It's high risk process involving going to the store so most of the profits go to the mules. Credit card numbers are cheap - just a few dollars per card. There is black market for that stuff - you can google and find a bunch of articles about it.

"But what I found out at that meeting were that all factors of safety were gone."

Many catastrophic "accidents", and I use quotes because they could have been averted had people not cut corners w/o knowing the full context.

* Chernobyl (after hours test by an untrained crew with an inverted fail safe design)
* http://en.wikipedia.org/wiki/Hyatt_Regency_walkway_collapse (design change in the field, very similar to the citicorp flaw)
* 3 Mile Island (indicator that triggered on switch rather than valve)
* Fukashima (cost cutting on seawall and generator snorkels)
* Ariane-5 (code reuse, dead code)

If you want to look at good engineering, look at the Brooklyn Bridge[5] and the DC-3[6].

Too many people don't design with proper safety factors. You build it, you test it, you test it till it fails and you understand those failures. I would trust another citicorp wouldn't happen because we can do realistic wind model, we can do an earthquake model, an anything model. Maybe we can get to a safety factor of 1 when everything is automated, when everyone has an off-site backup of their own brain but until then. Safety factor 6.

Running a real business requires actual hard work and determination... not just brains. Sometimes the technical brains don't even matter that much because you can hire them. Also, in most parts of the world entrepreneurship is a much harder "career" to pick and there are more bureaucratic hurdles and social friction. Keeping your lazy ass parked on a sofa while you steal some info that happens to be cc numbers and then sell them is much easier...

> Also, the most impressive part was that the two hackers were able to actually get to the US :-)

No, it's not. Travel visas are easy to get in US-friendly countries (Romania is much more US-friendly or "eager to kiss US ass" than most other European countries). Also, if you read on... "He took the traditional route with Oprea. The U.S. government sought the Romanian’s extradition. It worked". They could've done the same for the rest, the Romanian gov would have just handed them on a silver plate. Also, if they had been trialed in their country they would have most likely gotten similar sentences - $40k is not enough to safely bribe your way through the justice system and the prosecutors would have been either fair or most likely quite harsh on them. Maybe they were unsure they got all the evidence to effectively prosecute them in the US or most likely they just needed the elaborate phishing operation to make themselves look cool and get more funding for their department in the future, hence the excessive media coverage too, wasting tax payers money while jerking off with this role-play...

It's incredibly easy to catch stupid hackers in pro-US states, what they did could probably have been done by a smarter-than-average sysadmin helping a regular us police detective at 1% of the cost of all this "elaborate operation"...

EDIT+: My point is that the ss guys just picked themselves a few very low hanging fruits, got themselves excessive media coverage for it and spent way too much time and money on this.
Reminded me of the design flaw of the Millennium Bridge in London, where the engineers accounted for all resonance modes but one, the one that can be caused by pedestrians:

> Resonant vibrational modes due to vertical loads (such as trains, traffic, pedestrians) and wind loads are well understood in bridge design. In the case of the Millennium Bridge, because the lateral motion caused the pedestrians loading the bridge to directly participate with the bridge, the vibrational modes had not been anticipated by the designers. The crucial point is that when the bridge lurches to one side, the pedestrians must adjust to keep from falling over, and they all do this at exactly the same time.

http://en.wikipedia.org/wiki/Millennium_Bridge_(London)
It has already been built. Bane's point is that why doesn't dropbox buy THOSE services and see if they can expand on it. For example docker.io is a paid service for the above use case. Dropbox might be getting a cut from them, but if docker has successfully demonstrated that there is a market for this, wouldn't it be better form dropbox to aquire them and push in that direction?
I would say more density would be mandatory.

That can't happen without massive (and forcible) population relocation.

For example, the UK has a smaller land area than Oregon, but has ~64 million people, compared to ~4 million for Oregon. France is smaller than Texas, but has 66 million people compared to ~26 million for Texas.

The idea of "just getting rid of cars" will never happen for a similar reason. The U.S. is too big and there are way too many people who live outside the range of any reasonable public transit system that's been devised so far.

Maybe it will happen someday, but I don't think so.
Step By Step Tips On How To Change Your Home Insurance Policies
D1 and D2 are normal diodes in forward direction[1], in series they drop 2⋅0,7V = 1.4V. R2 just pulls them down. So the cathode of D2 will sit 1.4V below supply voltage.

Q1 in this schematic is acting as a current source: If conducting a reasonable amount of current, a transistor needs a base-emitter voltage of Ube = 0.6V. This is a PNP transistor[2], so base needs to be 0.6V below emitter, hence the voltage over R1 will be U(d1d2) - Ube = U(R1) = 0.8V. The current then is of course set (to first order, ignoring the base-current contributing) to be U(R1)/R1.

Why such a "complicated" circuit and not only use R1 to bias D3? Because a current source has a much higher (theoretically: infinite) impedance: Z=dU/dI, but dI=0 (stays constant) whatever the change in voltage (dU > 0) might be.

-------------------

1) forward direction: A diode that is operated, like a LED supposed to light, will have a certain voltage drop. For a standard silicon diode, this is 0.7V, a red LED would have 1.6V or so.

2) PNP transistor: A transistor has three terminals, base is the cross-bar, emitter is the diagonal line with the arrow, collector is the other one. a NPN transistor runs on a base current (technical direction + to -) into the base terminal and conducts current from emitter to collector, a PNP transistor runs the reverse.

Edit: emitter/collector mixup
