To keep track of your position using inertial measurement you need two types of sensor - gyroscopes, to work out which way you're pointing, and accelerometers, to work out how fast you're going.

An IMU in a smartphone would be subject to 10 m/s/s acceleration at all times under gravity, 50 m/s/s on a rollercoaster, and 100,000 m/s/s if you drop your phone on a hard surface.

Let's say we don't mind losing your location if you drop your phone, so we pick an accelerometer with a maximum range of 50 m/s/s.

Now, how accurately can we measure acceleration? The raw image setting on a fancy digital camera is 14 bits, which gives 16384 levels. CD audio is 16 bit, so it has 65,536 levels. Assume you can come up with a design that offers a 32 bit range, for a full 4 billion levels.

That means your measurements will be precise to 0.0000000116 m/s/s - pretty accurate, right?

The thing is, after 24 hours your phone will have an inaccurate estimate of its speed (0.0000000116 m/s/s * 24 hours = 0.001 m/s) and after 24 hours with that inaccurate speed estimate you'll have an inaccurate position estimate (0.001 m/s * 24 hours = 86.4 m) and the longer you leave it going, the bigger the error can get.

TLDR: You need super-precise sensors to do dead reckoning that stays accurate for long periods.
Did you all read some of the problems which arose? In one crash report, the drone took "off without permission from the control tower". In another, "an armed Predator suffered an electrical malfunction that sent it into a death spiral." A third was partially due to a "melted throttle part." A forth started when "[t]wo minutes after takeoff, the engine failed."

Another concern is that air control gives "priority to passenger planes and order[s] drone pilots to keep their aircraft circling overhead even when they are dangerously low on fuel."

Yes, some of the problems were human error. But from the statistics given, UI errors and improved navigation support give at most a 30% reduction in the crash rates. While what's needed is several orders of magnitude improvement to make it match the commercial crash rates.

Actually, that's not being cynical. A lot of engineering brainpower goes to the oil industry since it is so big. Almost any engineering company has oil and gas companies as their biggest customers. In comparison, hydroelectric is mainly maintenance and upgrades since most of the waterfalls have been built out.

HAHA, whatever happened to Intel pledges 80 cores in five years? (article from 2006) http://news.cnet.com/Intel-pledges-80-cores-in-five-years/21...

I'm currently in a Computer Science University program that I'm doing Online and it pains me to see so many high grades.

For instance, on one of the C++ homework we had, the median was 100%. It's fun to have good grades when deserved, but sometimes they feel thrown away and the only to not get good grades is to willingly not do as asked. (Oh and by the way, in this class, A+ is given for the 90-100% bracket.)

What the article should say to keep the 79% number in place is that '79% of the price was overpayment'. What you are saying is that 'they paid 482% of what they should have'. If they want to keep the structure of what they have written, I think ghshephard's formulation is right. They overpaid by 382%. Aren't percentages fun?

Firstly you need to look at the commercials of what you're working on. How big is the market and how much money can you make from it ? - can you grow from your current valuation 10x in the next 3-5 years ? - as that's what an investor is going to be looking for.

To start with I'd look at how many modern board gamers there are (also the rate at which that market is growing/shrinking), what percentage are going to be in your target market and at how much they'd be willing to spend on your product (assuming it's saas, if it's ad driven do the similar calculation based upon ad views).

Angellist has a lot of categorization data on angels so I'd recommend exploring that for angels that might be a good match with you. Starting the conversation with the fact that you've had an acquisition offer but want to looking at raising funding as an alternative will probably help you get attention.

If you want to remain independent you should also speak with your potential acquirer and see if that would be an option for them (i.e. either they fund you or alternatively acquire you but let you continue to run as a completely independent company.)

It depends on how you calculate the percentages. "Percents" are only useful as a tool for small numbers, say less than 10%: 90% is not far from 1/110%, so no matter how you calculate 10% loss or gain, you'll get numbers that don't stray too far apart.

Probably the author means that 79% of the money they paid (8.8/11.1) was thrown away, thus it was only worth 21% of what they paid.

Stating they paid almost five times too much is much clearer.

EDIT: We now know what you mean and have added to the list! Thanks!
The main stream languages currently do not offer enough abstraction for developers to make use of hardware parallelism effectively. Threads do get the job done, but nowhere as elegantly as I would want. Until that happens, we won't get to reap the full benefits of multi-core systems.

All the projects that I have done were incredibly flexible in terms of hours and billing. The usual process was that I would work on my own time as long as I was sending commits on a reasonable basis as outlined in a contract / discussed with the person contracting me.

There's something I always wanted to know, but was too lazy to look up myself (I have a CS degree (or will, in a year) and have taken microprocessor, assembly, computer architecture and courses like that, but none of them talked about multi-core, so I don't know anything about them).

When you have lots of cores, I think your bottleneck would be cache and to a lesser degree, memory bandwidth. You can't have multiple cores manipulate the same memory address simultaneously.

Am I right?

Little Inferno: How to unlock all 99 combos
The photos do not show up on my iPad (o, the joys of website with an iPad optimized experience), so I cannot see what the issue with the connector is about, but I would guess chances are that you will be able to buy third party connectors in short time.

For the iMac Mini, that is possible, and with such a connector, one can install a SSD as second drive in it (took me a few hours the first time round, but if I had to do it again, I think it would be an hour or so)

Of course that connector is hideously expensive (I guess iFixit would give it a BOM of $0.10 or so. I paid around $15,00, excluding shipping), but that is another issue.

Albert Einstein is attributed with a great quote:
“Everything should be made as simple as possible, but no simpler.”

I would argue that in the case of Git it's not about a single design decision. The whole design is very simple and easily understandable. Thus everything can be derived from the design decisions.

The design decisions also have clear rationales.

"Why something is better" and "why something has "won"" are of course different questions that deserve different answers.

No, no, theyre fully aware of that. The people behind this are the Halden Reactor Project, they already operate this small nuclear reactor that was (don't know if it still is) used to power a paper mill. The whole thing is just for some clout in world research. Leave it to the Norwegians!

nanoc, middleman and nestacms. i really like that you can push static markdown to the server it'll be exported to html automatically with static file caching as an added bonus. More elegant and easier to manage then a CMS or WebApp with Varnish.
If you're doing lots of reads, the L1 and L2 caches help things a lot. They are an order of magnitude faster than main memory access, so as you add more cores, this helps in the overall performance.

"But rising fees and increasing student debt, combined with shrinking financial and educational returns, are undermining at least the perception that university is a good investment."

Of course it's not ALWAYS a good investment. It depends on what you're investing in. That's like saying investing in equities is a bad idea, because poor choices lead to poor returns.

Why do all of the ballooning student loan conversations lump "college degrees" together? Area of study has a significant impact. I know of very few engineers who are being crushed by student debt. Of course if someone chooses to spend over $100k obtaining a bachelors degree in art, and has problems getting a job out of school, this has somehow become the fault of the university, or the United States, or society in general.

British Airways to Run Inflight Films During Takeoff and Landing
Culturally speaking, America does not necessarily incentivize merit as much as Germany (and Europe) for that matter. We are a nation of marketers and salespeople, which means: (1) personal networks are key and (2) ability to sell is key. Our cultural is built on the ability to control hyperbole and attention fulfillment (bureaucracy) as opposed to hard work (meritocracy). The skills you learn in personal networks (mostly social) in American universities are much more valuable than the ones attained from apprenticeships. In the HN/SV bubble view of the world, this is may not seem true, but largely outside of that bubble it is.

Therefore, what you are looking to do is make a massive cultural shift, not just fix a system. The best way you can fix our system is to continue to make yours (Germany) better. Competition breeds motivation to do better.

note - I respect that some of my comments are very much generalized. And while I'm from the US, I do live in the UK and have lived in Germany.

AMA Capital trades billions of dollars per day in the currency markets.

We are all engineers, and we all do a little bit of everything. We design and implement our own trading strategies and infrastructure, down to the networking code that ties us in to financial markets. We are a very small team (I am the only employee) and are looking to add one or two engineers who will focus on strategy or on infrastructure.

No experience or specific knowledge of finance is required. However, you do need to be at least interested in financial markets and to be able to implement your strategies carefully in C++.

nanoc [1]. It takes more effort to set up the basic rules for your site, but it's incredibly powerful. For example, my blog [2] can generate archive pages for my articles by year, month, and tag, with the generation handled entirely in "user space," without any undocumented hacks to the system or extenal pre/postprocessing. Another site I created using nanoc has the ability to take recipes that are specified only in the YAML content metadata, and expand them into full-fledged HTML pages - again, entirely in "user space."

In general, I find the ability to use code to control the site's generation very refreshing - the static site generators I had used beforehand (for example, Webgen) rely on configuration files to determine the rendering process, which for sufficiently complicated sites can be hard to trace. By contrast, nanoc's Rules file allows you to see and control exactly how a given file will be processed.

The code is also very well-written (it resists using the hard-to-follow Ruby magic that Rails and company tend to use), although were I Denis Defreyne, I would have written some sort of plugin manager by now.

Why is it far too dangerous?
You are somewhat right. You can't manipulate the _same_ memory address concurrently, but normally in multi-threaded programs your not doing that. Consider a traditional matrix multiplication program. You will pass each row/column pair to a core each pair occupying its own memory space ( or an address to a common memory pool that's read only), the core will perform the multiplication then it will pass that back to the parent to aggregate the result. The limiting factor in that situation is. Either the speed of the aggregating core ( you can sometimes parallelize that away by having multiple aggregation steps ) , or the amount of time it take to get all the data to the cores.

Being highly dependent upon acceptance by others is probably not a desirable trait in when it comes to writing for public consumption.

Most blogs aren't outstanding. Half are below average. That doesn't change what you have to say.

I've got three blogs I've started. I've got about half a dozen journals. Sometimes the gaps between entries in any of them will be a couple of years. Think less of me as a human being if you wish.
"We noticed early in the Stack Overflow beta that users desperately wanted to reply to each other, and were cluttering up the system with "answers" that were, well, not answers to the question. Rather than chastize them for doing it wrong – stupid users! – we added the commenting system to give them a method of annotating answers and questions for clarifications, updates, and improvements."

This is excellent advice not just for online ventures, but for business in general. Too much time is spent making rules and regulations to prevent customers from taking certain actions, when a lot more can be gained by understanding what your customers are trying to do naturally, and finding a way to support that.
For all our supposed good policies, we are still subject to mob rule and completely uninformed detractors.

People started caring a lot about power and mobile, combined with AMD basically shooting themselves in the feet repeatedly in the server space. AMD has delivered a large number of cores (you can cheaply put 64 in a box), but even for embarrassingly parallel applications, you'll struggle to get the same performance as a modern 16 core (real cores; 32SMT threads) Intel box due to smaller FP pipeline, slower clock speeds, etc. (note: not speculation; we have both types of machines in our labs)

Obama made the following statement in 2009:[1]

“I ask every American to commit to at least one year or more of higher education or career training,” Mr. Obama said in February 2009. “This can be community college or a four-year school, vocational training or an apprenticeship. But whatever the training may be, every American will need to get more than a high school diploma.”

The problem is I haven't seen any concrete initiative to do such a thing. That being said, the system is ripe for it's inevitable crash. Which in my opinion is a good thing. What the US needs is to crash and hurt. That will ultimately force change.

Yeah, this is why functional languages are so appealing for multicore programming.

Already in the middle 90's there where some HPC research with Lisp as the main language.

Functional languages have the ability to work similar to how SQL does querys, by abstracting how the DB engine works.

Of course we are seeing this type of language constructs come to the mainstream languages as well, because you really need to have some kind of inteligent runtime to fully explore parallelism.

It is a bit like assembly programming vs compilers. Sure clever programmers can beat most compilers when targeting simple processors, but when you level up with out-of-order executing, multiple instruction pairing, multiple level caches, NUMA, and so on, the compiler optimizer usually wins hands down.
This is almost exactly how it's already done in the UK, with exception that the loans are not provided by the university, but by an external loans service (The Students Loans Company).

You pay for your tuition by having x% of your salary deducted from future pay packets.

This does not “fix” anything. All it does is make the cost of education higher for those who earn less, like teachers and nurses. Why? Because they take longer to pay off their loans than Engineers, Lawyers, and those in Finance.

An let’s not even get on to the point that Universities are really there for research as well as teaching. We shouldn't be incentivising them to solely churn out future Software Engineers, etc...

In the UK there is a service called ByBox. They started out as lockers that field engineers could use to pick up spare parts. But they now also handle consumer deliveries.
Years ago we want to do this and I didn't know any tool for it. I develop the application internally and we used wget mirroring to statically deploy it.

Initially I thought it would suck but turns out wget is way better than I thought. With the combination of ssh etc. We build a simple script that deploys takes mirror of the website and deploys it.

After about 5-6 years, it's still in production with no issues. Internally it's a wiki style, simple database model home grown ASP.NET application.
