I ride to and from work and at lunchtimes every work day. I probably do at least 30km a day with 500m climbing. Here's how...

Block out 2 hours of your calendar at lunchtime every day. That's a non-negotiable slot for your exercise. Do something you love (for me its mountain biking) that makes it easy to motivate yourself to get out (having a group of similar minded friends helps too).

Work to 6pm - there's an extra hour that takes you back up to 8. For me after that is home and family time. If I need another hour I can work 9 to 10 or 10 to 11 when the others are in bed. It's a good quiet time to get a lot done without interruptions.

But here's the thing, I don't often need that extra hour because, having got out and cleared my head at lunchtime my afternoon is so much more productive that if I was stuck in the office all day.
The difference being that the gold was put there by natural processes, whereas bitcoins are purely artificial. It's more like spending a lot of money to win an easter egg hunt.

It's a game theory thing. It's more efficient if we all shop during a limited time and the retail workers then go home. However, if one shop is open when the other is not then people stop restricting their purchasing times and go to the open shop, forcing the competitor to also be open all the time. End result is lots of retail workers wasting time while waiting for customers around the clock.
The Trouble with Titles
Yep, I just switched. I initially made the jump solely because of uBlock's performance claims, but I have to say, it already seems much better overall than the haphazard Ghostery + Adblock combination I had before.
It's obviously untrue that only Germans could have been fascists as we had Italian and Japanese fascists, among many others, and, moreover the did execute their fascist beliefs to the extent they could resulting in some horrible things.
The book claims that integer numbers wrap around. Thats not strictly true. According to the C spec the overflow behavior is undefined, how ever on all hardware known to man it wraps around. Why does it matter? Because some compilers may assume no wrap around ever happens and use this to optimize.
The feedback on these streams makes this a really incredible idea. I just watched one where users were constantly noticing syntax errors, etc. and alerting the dev in real time of them. A few people on these streams are learning languages (like Lua) for the first time and powering through these projects with aid from viewers/commenters. Love it.
In addition to those hyperref settings, the code typography could be much improved. It features multiple fonts, colors and weights. I would use a single monospace font, with only a gray/black contrast for highlighting. Easier on the eyes and would look more professional.

Isn’t this just saying that not all proofs are constructive? That is, just because you can prove the existence of an object doesn’t mean you necessarily have a method for identifying it.

Also, there is some vague appeal to a substructural logic here, since by mixing up the forgery with the genuine article, you’re destroying the information about their origins, which is what prevents you from identifying the forgery afterward.

I’m not up on my modal logic, but I think this can be expressed as ◻∃x.P(x) ↛ ∃x.◻P(x)—proving the existence of some x for which P is true does not imply that there exists any particular x for which P is provable.
Another issue is the USSR were our 'allies' so we could not immediately condemn them and as you imply they were part of the victorious party so they could make their own history, so to speak and ignore their gulags and the starvation of millions of Ukrainians.

another thing I think is important is the immediacy. Germans directly controlled our fate --if they won, we'd have been their subjugate, PRC, USSR, while enemies, were not the 'death of civilization' kind of threat, so who cared what murderous and genocidal things they did to themselves. Another thing is someone to have it a cause to propagate the story of the events. Those victims didn't have as great an agent to carry their story of genocide and suffering.
Interesting point at the end that tools focused on web applications might not find this vulnerability.

It only claims that for unsigned integers, which is true. It also correctly says that signed overflow is undefined.
The value of gold mining is gold, which has various personal and technical uses. The value of Bitcoin mining is to support the blockchain. The value of which is, honestly, still unknown, but so far appears mainly to be transferring money.

So if we're measuring ecological efficiency of Bitcoin, it'd be something like cents or watt-hours or grams CO2 per financial transaction. I've never seen a rigorous comparison, but I wouldn't be at all surprised if Visa and Paypal are more ecologically efficient than Bitcoin.

It depends on the area, available work places, available workers, etc.

In some areas it's going to be as you say - if you want you can close up on Sunday. In other areas it means that lots of people want any kind of work and huge retail places will offer it - of course you have to work extra hours and every weekend. They can do it, because if you don't take the job, the next person will, because they need to.

The interesting alternative I've seen is limited trading hours on the weekend for shops over the size of X m sq. So you still can buy what you need, just not at the mall.
Why is the idea of a state run bank disturbing ? Would like to see a state run bank with digital sovereign currency proposed here in California to help fund the commons and to provide consumers with checking accounts devoid of parasitic fee's like overdraft, monthly maintenance, ATM, etc( maybe credit unions are close enough).

I recently discovered it. You can be paid for working on open source code. In fact you are paid in % of the product not directly in money.
When the product makes money you gain that much % of the product you own. Read terms carefully though, maybe you disagree with them.
I don't want to live where I do because it's an expensive neighbourhood. I want to live where I do because it's where everyone I know lives. Living somewhere else would mean abandoning friends and family.

Fundamentally that's the only thing that stops me from leaving the UK this second.

You make it sound as if it's an innate desire to feel important by living in a fancy place.
> You can use a bunch of different ways, but they are pretty average by any measure.

They do significantly better than other utility companies and are significantly less volatile than most companies that provide the same ROI.

> Zero day license v. 6-9months after release.

Network programming is broadcast over the air for free from day zero, just by putting commercials in it, and for that $9/month Netflix is producing a fair amount of commercial-free zero day original content on top of what they're licensing. That's really not it.

The math on this is very simple. It takes some number of dollars to operate a data network. It takes some number of dollars to license content. If you add these two numbers together, people are willing to pay more than the sum to get both of the things. It stands to reason that if the content is instead sold by some third party who assumes the cost of licensing the content, that cost can be removed from the cost of the data service while still allowing both to be profitable.
I think the author is trying to say that there is a concept of knowledge that is inherent to words "perfect forgery". That either someone knows the origin of an object and therefore it is not a perfect forgery, or all such knowledge has been erased and now there is no way to say that an object is not authentic.

I think this is something of a straw man argument. There is an entirely satisfactory functional definition for "perfect forgery" which is that an object is a perfect forgery if it cannot be distinguished from an authentic object by someone with no prior knowledge of the object's origin. This is what I believe common intuition would determine the word "forgery" to mean. An object does not fail to be a perfect forgery because its creator knows it is not real. It is a perfect forgery if it can fool everyone else into believing it is real.

Making zero knowledge of authenticity a prerequisite for a "perfect forgery" is to neglect that there are multiple independent minds in the world with their own viewpoints. I can know "that is a perfect forgery" if I know it will fool anyone without my private knowledge. Such knowledge is not incompatible with the object being a perfect forgery, because the most sensible definition of "perfect forgery" is that it would fool anyone else, not that it has already fooled everyone including me.

Would I like to sack someoone after seeing them at work..... Not so much. It's hard to sack people you have met.

Good article.
> "two of KIC 5520878’s characteristic frequencies—with a 4.05- and a 6.41-hour cycle, respectively—had a ratio of 1.58, close to the golden mean, an irrational number,"

there are lots of things in nature - and everywhere - that are "close to" the golden ratio, but few that are extremely, tantalizingly close. 1.58 is not close; there's no story here. call me when it's 1.618*

I had an external Seagate hard drive that seemed to me that it had a high quality look -- it was a satin finish plastic, which resembled the plastic used on power tools. The next upgrade I got was a smooth shiny black plastic which I hated from the beginning, as it would get scratched up too much in my laptop bag. But guess which one most other people prefer buy?
Annotated code: Circles bouncing off lines
In the 56k days people could imagine sending audio one day, and dream about video. If we can't imagine a compelling use requiring gigabit, maybe there just isn't one.

I'm hoping that some experts here could clue me in, because with wired U.S. average according to Akami at 11.5 Mb/s it seems that a neighborhood wireless would be plenty fast for at least the near future, and much cheaper to build and maintain. Having fiber direct to the house would be better of course, but to me it just doesn't seem worth the cost.

Most of the proponents of Sunday shopping pitch it as a personal freedom: You should be able to go to the store and buy something if you want it.

However, it's not strictly a personal freedom since it involves another entity : The store, and all of the supply chain involved in bringing you that good at that time.

By saying one has the right to buy on a given day, one must also say that one doesn't have the choice to sell on a given day. I realize that an employee could just refuse to come in to work on Sunday in order to sell a product, but that's just not a choice in many situations.

Finally, regarding small businesses getting hurt: I don't see an argument that working an extra day will magically make them more profitable. If they're just barely scraping by selling 6 days a week, I don't think they'll do much better by working 7. In many cases, it could be argued that they're spreading 6 days of profits over 7 days... meaning that they work more for less.
3 year old diva performs Let It Go
Exactly, if we take this assertion, then we'd have to say that Germany had been very backward till recently when most stores were not open beyond 6PM[1] and people had to rush out of work by 4PM to buy their groceries. Thankfully, as far as I understand it, that has been relaxed over the last few years.

First Rule of VR: Don’t Break the Presence
Same goes with Doctrine.

You can write crazy complex hydrators, or use simple result set mapping for populating custom query results into objects.

Nearly all of my complex queries for some analytics software I wrote lives in sql statements that aren't inlined in the EntityRepository of a specific entity. ORM's are nice, but doing complex stuff in DQL (doctrine) or the other query builders is more hassle than its worth.

Oddly, they mention azithromycin, but I found this:

http://aac.asm.org/content/50/6/2042.full

which says:

"These results were compared to the inhibitory profiles of other antibiotics that function by inhibiting bacterial protein synthesis. Of these, chloramphenicol and tetracycline were significant inhibitors of mammalian mitochondrial protein synthesis while the macrolides, lincosamides, and aminoglycosides were not."

Seems like "doxycycline" would be more precise than "antibiotics"? After all, I assume this effect can not true of those "antibiotics" that are thought to increase the risk of cancer? (I am thinking in particular of metronidazole, and I put the word antibiotics in quotes because metronidazole is a very strange drug that is difficult to classify, and even though it is sometimes used as an antibiotic, it was not initially thought of as an antibiotic.)
The forging statement seems rather silly.
$20 -> $200 is still a pretty good mark up, plus in cheques or similar paper based money transfers it's normal to have the amount written out in words as well as in numerals.
Measles was declared eradicated in the US in 2000. Thanks to the anti-vaxers, it's back.
Well, as far as I know, Trotskyism doesn't oppose the Marxist-Leninist concept of the single-party state ("democratic centralism"), while maintaining an "inner-party democracy".

Trotsky himself had committed to the side of the Bolsheviks, and didn't so much oppose Lenin's ideas, but Stalin's, though he also disagreed with the former about the need to expand the revolution to other countries.

In general, Marxism-Leninism, Trotskyism, Stalinism, Maoism, etc are all more-or-less aligned ideologies with an authoritarian bent, and were opposed initially by the Mensheviks, and later by various Libertarian Marxist and Socialist movements[1], and of course by the anarchists.

I just sharpened the kitchen knives today with my set of Japanese whetstones. After you've done it often enough, you can tell a lot about the blade steel by the swarf it makes and how it feels.
Actually, due to the fact that my kids are grown up and out on their own, I am not nearly as concerned about getting top dollar (or climbing some career track) as I am about working on something interesting and having done something I can look back on 10 years from now and feel that my time was well spent.
This is actually a remarkably good point. The key concept here is that Bitcoin mining -- even at a "Forex loss" -- will essentially trade electricity for Bitcoins, which can be used to purchase other currencies. Depending on what the miner values their local currency at, this can still make financial sense.

As an example: suppose you are a resident of country X, and you have 1000 XUnits that are valued at 1000 USD, but there are capital flight restrictions such that you can exchange your 1000 XUnits for only 300 USD. And suppose that you need to exchange your XUnits to USD, for whatever reason. You then use your XUnits to buy electricity and mining hardware, and generate Bitcoins, and sell them for 750 USD.

Note that you could try to do the same with e.g. steel, barrels of oil, or widgets, but with hardware you'd be subject to import/export taxes, and the entire operation would have much higher overhead costs (comparatively, setting up a mining farm is pretty cheap).
If you want to amuse yourself, count the times you see people write things like "$10 dollars". It's quite common. Technically it should mean 10 square dollars, whatever that is.

Years ago an acquaintance of mine told me about a bad experience he had had with some cell company's customer service. It seems that the contract he had received had said that he would be charged for data service at the rate of ".02¢/kilobyte". (This was in the very early days of cellular data, so prices weren't well established, and I'm probably not remembering the correct number, but as you'll see, that's not the point.) When the bill came, he found that he was in fact charged 2¢/kB -- 100 times more than he expected. He called to complain, but was unable to communicate to the customer service agent that, correctly read, .02¢ = $.0002. The agent apparently looked at the notation ".02¢" and read it as "$.02".

One can understand the psychology of this. The notation ".02¢" contains two indications that the value 2 is to be multiplied by 1/100: one is given by the position of the decimal point, and the other by the use of the cent sign instead of the dollar sign. But if you read those two indications as redundant rather than independent, you get the interpretation used by the agent (and apparently also by the person who wrote the contract).

So I would suggest that the "$10 dollars" thing is not as benign as it appears. Mathematical notation is not supposed to have redundancies in it, and we should not get used to seeing them there -- particularly when money is involved.

This is very similar, if not the same, technology as Husk Power Systems. HPS had a lot of press around 5 years ago for going to villages in India which grew corn and burning their husk for power using tech from WWII. They were so successful that corn husk became a commodity in the villages they entered. A part of their model was also to train locals to become engineers and manage the machines themselves. Pretty incredible value add at many different levels.

The British put their currency symbol in front as well.

Malaysians write theirs like "RM8"; RM being their local currency symbol despite the ISO one being MYR (this happens because ISO puts the country first but many countries would write it out the other way around).

A bunch of other countries don't write any symbol at all, only the number. Some, like Indonesia, also have an implied thousands (000) at the end, since their base currency unit is very small. So you may see "8" but it means "8000 IDR."
Nope. In Latin languages the number comes before the period (2015 DC). That was a hard detail of English to learn...

But in about any language the currency symbol comes before the number.
I'm just starting to flesh out a new database system for an SF government related agency, ground level, replacing something almost 15 years old. If there is a single person or two out there that wants to sit in on a meeting, brainstorming, it would be much welcomed. 501c3 org. I'm not even a DB guy, more of a general tech solutions architect, but I'm curious (as others on here are) just how much waste is necessary with these kind of projects. So far we've spent about 20k on maintaining the current system, maybe even more over the past 2 years. Anyway, I could go on and on, but if you're in SF, drop a line for lunch/coffee on me, dan at sfpretrial . org

It is strictly a personal freedom. No one is forcing someone to sell. But if enough people want to buy on Sundays enough people will sell on Sundays.
Huh. I think a big point of things like tarot cards and the I Ching is exactly to short-circuit rational processes and let people come up with answers intuitively.
Thanks for the info+link, I'm going to stay away then. I agree, this is so important in the book.
