If it's single address space, I wouldn't call it Virtual Memory. That sounds more like what the Blackfin had. I'm going to watch their memory talk today (when I can get a free 90 minutes).

[edit]

Reading the Memory page on the wiki, it is indeed SAS with an MPU. Obvious difference from Blackfin is that you have 2^28 times as many addresses available.

It would also be interesting to see how much smaller a PLB entry is compared to a typical TLB. TLB misses are responsible for a surprising amount of performance loss on some workloads as L2 caches have gotten so much larger, so if they can have e.g. an order of magnitude more entries in the PLB it would be a big performance win.

[edit3] It just occurred to me that your PLBs could be as slow as your L1 cache with little impact on performance. This can also let them be physically larger than your TLBs.

Assuming the ISA is designed for efficient PIC/PID a unix-like shouldn't be too terrible to port from that difference alone. I know there have been SAS unixes before.

I have run into the 46-bit userspace limit on linux AMD64 (think mmap), so I'm somewhat concerned 64-bits may not be enough in the future as disks get bigger, though that's a long way off as you have 2^14 times that room under this scheme.

[edit2] It's a 60-bit SAS, not a 64-bit SAS
That's a whole lot of words to say "they took our jobs".
Then again, as long as the big pharmaceuticals still have a profit margin of 25% or so I don't think they are the victims here... Point is that there are two sides to this coin: the pharmaceuticals charging way too much for their medicine and the Indian companies copy-catting/piggy backing on the US R&D
Which is a good thing I think. The sad thing would be if it had no reaction at all because it was dominated by trading algorithms which don't panic. Then I'd start to wonder whether or not it was a market at all.
In case anyone else is looking, here's the story source for the last picture:

I don't think they're questioning the business efficacy, I think they're questioning the need for protections for the industry.
Very little; which is why pharma research is such a problematic industry. We need to seriously rethink the way we develop drugs:

1. Research does not get funded unless there is a commercial market for the drug. This leads to overfunding of maintenance treatments of chronic diseases like diabetes, because they are widespread and never really go away. Meanwhile, the system does not incentivize investment in things like antibiotics (because the next wide-spectrum antibiotic that gets developed will likely be force-licensed for public health interests).

2. For the vast majority of life-threatening diseases that anyone is likely to catch, the most effective drugs are already off-patent. Unless you can significantly improve outcomes, how can you compete with a generic that works 95% as well as your new drug?

3. The only country currently willing to pay sticker price for pharmaceuticals is the US. Every other country negotiates prices down to a fraction of what the US pays. The idea of a month worth of pills costing $400 is unheard of outside the US. So US citizens are either directly subsidizing the cheap drugs for the rest of the world, or we're getting taken for a ride.

4. The majority of the cost of developing a drug comes in the clinical trial phases. This cost is the same for any drug -- and most of this is marketing budget. Studies are designed to have specific outcomes so they can be listed as bullet points on information sheets given to doctors -- doctors are smart, but they're busy, so if you can do a study saying that "outcomes in high-risk patients were improved by 30% over the leading treatment", the doctors will never look to see what high-risk patients means, whether the study was done correctly, or even what an improved outcome looks like for those patients. Never mind you may have done the study 8 times and this outcome was only observed once.

Pharma is broken. Our current pharma industry is geared towards "lifecycle" drugs that alleviate symptoms rather than fixing any underlying problems.
But up to what point ? What happens when investing into research becomes too risky ? This is a tough problem.
Do people typically put qualifications from a Coursera class on a resume? The credibility of a college education in the professional world can't be replaced as easily.

I've taken a few Machine Learning / Big Data courses using MOOCs and done enough homework such that I get a certificate. But I'd never put it on a resume because that would imply mastery of the subject, and no MOOC is as sufficient in coverage as a normal college curriculum.

I took the MOOCs mostly for context in areas where online tutorials are terrible; at the least, it'll help lead to some sweet blog posts. :)
"The U.S. water recycling system produces... slightly more than the Russians [because] NASA takes Russian urine... 'collect it in bags, and then the crew hauls it over to the U.S. side,' Carter says. 'We don’t do 100 percent of the Russian urine. It depends on our time availability.'"
All projects have the stuff that's exciting and fun, and all the other stuff that's boring and dull, but needs to be done. I try and handle some of that boring dull stuff early when I have lots of energy, and try and save more of exciting stuff for later.

I've had trouble launching things when I've left that boring stuff till the end, and boy does it drag on getting that stuff done.

I'm not surprised it made no sense. It's from a school of writing that uses poorly defined dramatic terms like blood-letting and secular bull to make it sound like the author knows something. If you read someone like Buffett who actually makes money trading stocks you get a completely different take and vocabulary.
Saying that in face-to-face conversation does not make it civil.
Singularity evolved into a few other projects, some of them now on .NET.

The compilation of .NET to native code on Windows Phone 8.x with MDIL, and its successor .NET Native, can be traced back to Bartok. The Singularity's AOT compiler toolchain for Sing#.

Microsoft research then went on to Drawbridge, Midori (still classified) and now IronClad.

Then as programming languages that grew out of it there the M# which was mentioned around two years ago and not much more, and Dafny being used by IronClad.
I like Coursera, but I've been waiting on a class to happen for the past two years and they keep rescheduling it. I really wish they'd address it by either canceling the listing or actually making it happen.

> great if you want to extract money other's productivity but not so great for the market as an economic structure

No this is not correct. Options are derivatives that are traded on a secondary market. When you buy an option (or two options - call and put - in the case of a butterfly spread) you are buying from someone who is selling the option(s). Hence you are not "extracting" money from others, you are engaging in a voluntary bet with another person.

Derivatives are very important tools in a modern economy. They are frequently used by businesses and individuals to hedge their exposure to volatility and uncertainty. For instance, if you are close to retirement and still own some stocks, you could hedge your downside risk by purchasing put options. This behaviour has no negative effect on the primary market.

> If you extract wealth without improving the market itself how are you a participant?

You are a participant in a secondary market, not the primary market. You only gain wealth if you bet correctly - you still have risk like any other traded asset.
Effectively bypassing kptr_restrict on Android
Um, no, people aren't paying to be surveilled. They're paying to have an internet-enabled entertainment and information device in their pocket. Any surveillance is a side-effect, and one I think most people would not agree to if it doesn't provide any benefit to themselves.
I call your hypocrisy.

Drug trials are expensive and the ROI is not stellar at all. Without the prospect of copyrighting the result there would be way less efficient yet safe drugs for all of us. As a fact pharma companies - despite the conspiracy - are nowhere the biggest or richest companies of the world (Pfizer roughly #48). So why did you decide that actually pharma companies - and not for example YOU - should sponsor the treatment of the poor of this world? Do you equally expect Nestle to feed the hungry for free because it produces food?
Honestly, I think that's the best way to learn. A lot of great programmers/entrepreneurs end up taking an autodidactic approach to learning whatever they need to learn to become successful. I always use Sean Parker as an example: https://en.wikipedia.org/wiki/Sean_Parker

I don't buy into the belief that the only way to learn something is by taking a course or getting a degree. I can buy the same programming book or the same physiology textbook used in a course and read it on my own. The only problem is that, unless you really do something outstanding to prove that you know the material, its not something you can put on an application/resume.

Statistically, all matter on the scales we're used to is only found away from earth since the universe as a whole (including dark matter) is something like 10^30 times less dense than earth.

So if dark matter is found independently of matter* there'd be on the order of 10's of mg of it in the whole earth which would seem impossible to ever measure via gravity.

* Probably a huge if, it's just a thought experiment
Not only that, the title is outright wrong. They have two water systems up, yes. However they already HAVE agreed that the silver-ion system is preferrable and NASA plans to switch to it.
> Online surveillance has better arguments against it but 90% of Internet surveillance is by permission (possibly given by people who are not fully aware they are giving it). It is not as bad as this hyperbole makes it out to be.

No it isn't. Please read up on GCHQ and their pals NSA and what they do, e.g. 'dragnets' and other mass surveillance which absolutely isn't 'by permission' but is happening at a massive scale.

Also, you can claim you're one of the most paranoid people you know, but your whole post sounds like a post written by one of the 'I have nothing to hide so nothing to fear' group. If you'd be even a little bit paranoid, you wouldn't be ok with whatever surveillance, CCTV cameras etc.

MIT Course 'to Inspire Next Generation of Bitcoin CEOs'
Unfortunately, Tom's analysis is biased towards EKR and Salter being uncorrupted, when is too big an assumption. And if you bring it up to him, you are treated with mockery and derision for even thinking about it, because once you question one crypto expert's motives, you're obviously on a witch hunt.
Drug companies do a great job at developing drugs, but then turn around and spend twice as much marketing them. Doesn't it seem like it would be a better system if government(s) set up drug development bounties, and pay the bounty in exchange for the patents? Drugs immediately gain generic availability, and the drug companies no longer need to sell their shit with Super Bowl commercials in order to make a profit.
But that is still far away from the '84 doctrine of "watching everyone all the time".
How to make your GitHub profile seem active
Command line use. You grep some files, and think, "man, this really needs this ONE LITTLE FILTER". So, you pipe it to `perl -e "..."`, and soon have a very short program that you iterate on a few times to make sure you have right, and then you pipe it through the rest of the toolchain.

I don't write Perl much anymore, but that was far and away my __favorite__ way to use it. I love coding in Python now, more than I ever liked programming in any language (except perhaps lisp), but I still don't feel I can use it on the command line that way.

In the context of a Python program, I can't see the value of a Lovecraftian lambda (unless maybe in code golf comments?), but I found this article very appealing mainly because it's quite a feat. Doing anything nontrivial in a lambda is a pain in the ass, so the fact that someone wrote a tool to do it is awesome.

I've only taken a couple courses from one of these mini-degrees. I did feel like the quality was iffy, but I don't feel like I've seen enough to make a call on whether the problem was the instructor or the mini-degree.

The main problem was that the course was unfocused and rushed. It felt like the instructor was trying to touch on every single thing a person might learn over the course of a graduate level course. But since the class was shorter both in terms of number of weeks and time students could be expected to spend on any one week, it just resulted in a lot of very shallow treatment of an immense number of topics. Some lectures were barely more than a recitation of paper titles.
> That's the whole idea of patents, isn't it? Just like you can't import medicine that infringes patents you also cannot parallel import iPhones or start making jeans and attach a Levi's tag to it...

That's not a good analogy. one could make an phone that has the exact same specs as the iphone or jeans that is the exact replica of a Levi's ,without the brand and the logo on it and it would not be an iPHone or a Levi's Jean.

it might not be legal but it wouldn't be shocking. The fact that you can't reproduce a formula ... TO SAVE LIVES ... is shocking.

US government prefers people dying because they can't afford meds rather than violating something that has nothing to do with the free market, ie , patents. We're not talking about phones or clothes here , we're talking about medication people's life depend on.
Case study: 124 percent more prospects by running FB and Twitter ads to Email list
The basic design of the A4 engine in the V-2 was a sound concept. The reliability of wartime production was held back by the deteriorating conditions and post-war testting was held back by the aging of the captured components. The US and UK used nothing but captured parts, preferring to iterate on the original design rather than build new components for an old rocket.

The US took their testing data and combined it with the fruits of Operation Paperclip's R&D to create the Redstone program. The Rocketdyne A7 engine was a direct successor of the A4 and was reliable enough to put the first US astronauts in orbit during the Mercury-Redstone program.

In short, an A4/V-2 would have been reliable enough to serve as the foundation of a British space program as long as it was built to spec without the material substitutions carried out due to wartime shortages.

What a fantastic overview of the past, present and future of UI flow and structure! There is a real need to step back and consider the available architectures and to build forward to a more natural and synergistic solution like Cycle.js.org.

I Really like the third diagram in the Nested Dialogues section and where it says "The wiring of Observables between layers of Dialogues is a data flow graph". This reveals that interactive event flow is primary and is what drives a UI, weaving through components like the nervous system does in the human anatomy.

In the diagram we are looking at an emerging and clear way of defining app flows and structures. There is potential here for a drag and drop IDE editor where the over all app can be architected and generated.
Doctors told me I need to move around a bit, to get blood flowing etc. 30 minutes sounds like what the doctors said.
I love JSX because all it is one big javascript expression. I disagree with the statement

For some reason, React’s JSX make this unnecessarily complicated by not being able to use if statements inside code blocks.

Using if inside an expression isn't javascript! It would be some shitty templating language, and I'm grateful it didn't turn out that way.

I got my CS degree in 1984 and did programming on my own from 1977. I'm still in development so I can be your time traveler. Yes and no? If you've taken the GUI, drag & drop components route I think you'd have trouble. Another big sticking point would be if you've only worked in languages with automatic garbage collection. My opinion is you need to have malloc and free, or the equivalent in assembly etc. ingrained in you to get it right, to make sure your routines free up memory no matter the exit points. Of course you could be a modern Linux C programmer using vi and you'd be their ninja rockstar on day one. Comparing the two eras I'd say you could do a lot less back then but you were expected to do a lot less. Standing up a database, using a connector to it in your language, getting input from the user to put in the database; 1-2 days now, weeks or more back then.
The <aside> styling was an experiment, since I'm really not sure how to style those nicely.

Unfortunately this doesn't work well at all on screen sizes small enough that the aside half fits.

The article says "Instead, the spaceman (and only a man was considered) would have been launched on a parabolic trajectory some 300,000 metres above the Earth."

I think that's a mistake. The V2 had a range of about 300 km ("For the V-2 rocket, just reaching space but with a range of about 330 km, the maximum speed was 1.6 km/s" - https://en.wikipedia.org/wiki/Sub-orbital_spaceflight#Speed.... ).

The BBC article goes on to quote “Megaroc was essentially the Mercury-Redstone.” From https://en.wikipedia.org/wiki/Mercury-Redstone_Launch_Vehicl... we see that Mercury-Redstone didn't quite make it to 200 km altitude.

According to http://www.planet4589.org/space/jsr/back/news.526 , there have been no suborbital flights above 192 km.

EDIT: Nope, I'm wrong. Megaroc was supposed to get to 304 km (one million feet). http://www.bis-space.com/what-we-do/projects/megaroc . Indeed, it appears that the name is short for "Mega[foot]roc[et]."
Basically it's just propaganda. They're using complicated econospeak trying to confuse you into thinking that everything is alright.

In reality, nothing has been fixed since 2008, and Western economies are in shambles behind the scenes. It's a confidence game. At this point, investors are close to losing confidence, and when they do, a big crash will happen.

Yes but that fact doesn't have any scientific basis, it's just pure coincidence. There's no reason why it didn't happen other than the fact that it didn't. The stock market on the other hand, indicates the overall health of the country. It's not a coincidence that it keeps going up as the wealth of the nation goes up.

Recently in baseball, all 30 teams played on the same day, and all 15 home teams won on the same day. That hasn't ever happened before. Why hasn't it happened before? Not because of how unlikely it is. It hadn't happened before because it hadn't happened before. Because it happened now doesn't mean it's more or less likely to happen in the future. It doesn't mean baseball is changing. It doesn't mean anything. But a long term downward trend in the stock market? Means death for a nation's economy. Even a short term downward trend does significant damage.

Football and the stock market are not as closely related as you may think.
