I know it's not the same as urban street parking, but in a mall I just saw in Guatemala City, each parking space has a sensor. This lets them display realtime information on which areas in the parking lots/garages have free spaces. Each space has a red or green light, so as you drive through you can instantly spot an open space. Pretty neat.

Those numbers are bleak. I think it has more to do with "The enemy of my enemy is my friend." than with any sort of corporate respect.

It's really more about the freemium vs direct payment models competing with each other. Though I would say the device makers and application developers have already chosen which is why Microsoft is suing easy targets like Barnes and Noble to give other vendors pause.

Ask HN: Feedback on our "consumer analytics" startup

We are 8, 5 devs including myself. Not huge but still costly.

We do use open source libs (mit license), its the combinations which is quite unusual. But we could leverage some of them like web2py.

About mercenary coding, I am all for it as I know my team would do right and create a good margin on each project. What I wonder is how to promote a team like us.

Delegating the sales at the international level might be indeed the best option. Some of our customer are foreign and in bad shape but someone with more connections could be more successful than we have been.
Open sourcing (even partially) the product is also on my mind. The increased visibility is indeed something to consider.

Thank you for you input,

Chinese entrepreneurs see Apple's App Store as entryway to global market
There is not enough information in your post to offer any serious suggestions. What is the product you currently have in the market? Did it require special domain expertise? What happens if you decide to close the doors--how would it impact your current customers? Is there any potential for expanding your market? Why would someone want to buy your company? What is the company culture like? Could you could accept outside direction and management? Detailed answers to many of these questions are likely to not be appropriate for a public forum like HN. Your profile has no email address for contact.

A friend and I were discussing this once. I don't like horror films because of the gore. He told me that when he first started watching them, the gore creeped him out and made him uncomfortable. After years of watching them though, it doesn't faze him at all. To me, that's the very definition of media changing someone. Of course that doesn't mean he's going to become an axe murderer, but it had a noticable impact on his thought patterns. Take someone that is unstable to start with, and maybe... ?
I live in Slovakia and I find this article misleading.

Behind paywall are only some articles (e.g. not the daily news), comments and some smaller specialized site sections.

Thanks for asking. I have no problems talking about them.

All the opensource stuff listed here http://akash.im/code since Jan-2011, were according to the 1-per-week rule and none of them commercial. The arduino ruby gem was a little bit popular. When there's only 1 project in the month, you can assume that I've been working as a remote intern or have been doing my last freelance work :)

You can see that I clearly did not keep up with the 1-per-week expected results. Like I said, it was 2 per month in the end, but I still practice it. Along with it, since last month, I also make sure I read one-interesting-paper-a-month (was the Amazon Dynamo paper last month).

Yet to work on something this month. This month, it'll mostly be a scheme interpreter (R7RS-small spec draft#1) and a light-weight key-value store for fun and then (possibly) get a job as a remote full-timer at some startup (remote jobs are tough to get I guess).

Besides, what opensource stuff do you write? (just interested in stuff and trying to make friends to collaborate).

Tip: Point your customers to http://omgipv6day.com/ , now.

The site will tell if your Internet access will be fine on World IPv6 day. A positive answer means that you either have IPv4 only connection (no broken IPv6 DNS responses or routes), or have a fully operational IPv6 nameserver and route to the Internet. A negative answer means that your computer was tricked into using IPv6 while no actual IPv6 connectivity exists (and thus you are going to have problems on June 8th).

"We Are Going to Japan": Justin Bieber | NEWS 365
This is the oldest, yet often useless, criticism in the world. Statisticians know that when they are observing correlations they don't have statistical evidence for causation. That requires you to take a step back, decide what other variables could cause something, and test for that.

But here it's more than some vacuous claim to correlation.

Do you get unemployed as a BA first, or do you get your BA?

Econometrics is all about identifying causation in correlations in natural data (i.e. you can't run scientific experiments on people's lives, like telling random sample of people to go to college and others to not). Here, you just need intuition to realize that one thing consistently is a prerequisite to another, to realize that it's not just some statistical garbage.

There are three possible models to explain the correlation:

1. Something influences both one's propensity to get more education (E) and not get laid off (L).

2. One's education determines one's propensity to not get laid off

3. One's propensity to not get laid off influences one's education. This is nonsense.

In a Bayesian network, you can visualize 1. as features f0,...fi (say race, parents' income, etc) influencing both (E) and (L), with (E) also influencing (L) directly. 2. would be a set of features f0,...,fi influencing (E) but not (L), with (E) directly influencing (L).

So to conclude, "This chart only shows correlation" is a useless comment to make unless accompanied by an analysis of the possible probabilistic models that the evidence supports.
Anybody know what hardware those benchmarks were on? Is it actually durable? They mention problems with writeback caching, but are they at least durable from the OS perspective? How well does it scale?
replacement is a strong word when you consider that you are talking about:

get/put/delete vs http://redis.io/commands

How Google can prevent Facebook from taking over
I think maybe you don't understand what correlation means. That the variables of employment and education are correlated means that a change in one variable means that the other variable will change. That is, the two variable change together. It's not necessarily casual relationship but there is a relationship.
2011 Logo Trends
sure, dependes of course if you're using redis only for a simple key value store.
Note that this is not a database server, like Redis or Memcached. This is a database library, more along the lines of sqlite. In particular: "There is no client-server support builtin to the library. An application that needs such support will have to wrap their own server around the library" and only one process can access a database a time.
Unemployment certainly isn't the cause of education; Thus if there was a third variable causing both low unemployment and education it must be some intrinsic quality of the individual, such as "hard work" or "intelligence".

Thus it is still good advice to tell students to work hard and do well in school, rather than saying it's okay to be lazy and not pass exams because, well, "education is only correlated with employment prospects".
This is pretty neat, and different from many other "simple" KV stores, because it arranges things in key-order on disk, and permits forward/reverse iteration over keys. (ie, range queries are cheap)

edit: it's actually full log-structured merge, sstables, memtables etc.

Yeah, nobody ever outsources technical work. ;)

I don't think anyone is ever entitled to work, whatever the industry. Especially if someone else wants to do the same work for cheaper -- be it with a machine or in another country.

If you tell me someone lost their job and is having a hard time supporting their family, I do feel compassion. But the tool I reach for is charity, not a free job.

It's not like there's a shortage of opportunity. If your skillset doesn't support your desired income -- especially if you find yourself unemployed -- go get some new skills. Whether it's reading a book about PHP or learning to repair refrigerators at the local community college, someone can pivot in a few months' time. (I wish this were more of an expected fallback; it seems like simple common sense to me.)

In the mean time, the rest of us have cheaper products, and are that much richer.
Based on their numbers it looks slower than TokyoCabinet but still much faster than BerkleyDB. Would need to design a head to head benchmark.

I don't think Redis is a good comparison as that's an in-memory database so better suited for the 10% of hot data you'd need to cache. Whereas disk stores like TokyoCabinet and LevelDB would be great for storing the other 90-100%. If your use case involves a large dataset and you don't have terabytes of RAM lying around, that is.
The quote you cited was not an example of scientific collaboration or espionage. In this case, yes, the espionage probably endangered someone's life, given China's human rights track record.

I see your point, though, and agree that science collaboration is not harmful. However, I think that the article was mainly focusing on Chinese military advancement, as most of the attacks cited in the article were on our military infrastructure. Again, I would say that a more advanced military will endanger people's lives.
When reading this I feel like it's what I think about software. The only point where it doesn't work is the one entitled "if it has screws, they shall be turned", but still, it's a perfectly good metaphore.
Good points. I, however, am dispirited by watching comments devoid of value not getting subjected to the same sort of enthusiastic down-voting as comments that reflect exasperation at those very vacuous, time-wasting comments.

A culture that prefers polite nonsense to harsh truth-telling is a weak culture. At the very least, both should be punished, but I don't see that here.

I can't find quite that anywhere either, and in particular no movement from the cello suites starts with it or anything that sounds close to me.

The beginning of the first movement of BWV1023 (it's a violin sonata) isn't a million miles off, but it certainly isn't quite it and it's a violin rather than a cello.

(Are you absolutely sure it's Bach? Not that I have anyone else in mind.)
Ask HN: Making source code avaliable for commercial software
I develop a piece of commercial software. It is free for non-commercial use.

I distribute binaries, but many users have expressed interest in having the source code available. I would like that, and think it would be great if users could modify the source and distribute changes, as long as it wouldn't undermine the commercial sales (since this is what is financing the development).

I guess this rules out a "true" OSS license, but I would prefer using an off-the-shelf license if possible.

Some have recommended a CC non-commercial license, but CC themselves discourage using their licenses for software.

Does any HN'ers have experience with this issue? Under what licenses do you distribute your sources in commercial startups?
Entertainment industry people often collect unemployment between jobs, so my guess is they report as unemployed.

The article is trying to show causation from correlation, the reasons for the number of engineers in India have nothing to do with the Independence, Wars with Pakistan, ISRO, DRDO etc. A much better and plausible argument is Y2K, a strong domestic IT sector and herd mentality.
If you're trying to claim that giving Chinese youth student visas to study at elite western universities will create a more liberal, pro-western intelligentsia in China, you are flatly wrong.

The Chinese who come here (to the US) are part of the growing Chinese middle- and upperclass and tend to be the most nationalistic of all. Talk to them next time you get a chance; ask them what they think of democracy and freedom, and they'll likely spout PRC government propaganda about how the "Chinese people need to be controlled." We make them into scientists and engineers without succeeding, and perhaps without even really attempting, to make them democrats. We are potentially creating big problems for ourselves and our western and east Asian allies down the road by equipping China with the skilled professionals it needs to produce the weapons of war to threaten the free world.

As for protectionism, if it really bothers you, perhaps you should complain about China's "luxury tax" (import duty) and government-mandated technology transfers for access to their production and consumer markets. China is easily the most protectionist member of the G20.

Nah, it's not BWV1023. I could be wrong about it being Bach, but I definitely feel like it is, and when I asked my mother if she had any ideas she immediately went to "I think it's a Bach cello suite", so even if she was wrong about it being one of the cello suites, it's still looking fairly good for being Bach. Plus it's definitely Bach-esque.

And I can't bare it, I've heard it so many times, have definitely heard it in concert if not even played it myself when I was younger, just can't quite remember.
