That's not how that works.

To blind a security camera, you need to exceed its static range in the area of the CCD that your face occupies.

If camera optics were perfect, you would have to lighten or darken your entire face to the extent that your face either maxed out or minned out the CCD at its current exposure setting. (So having a "too well" illuminated face would actually help hide from a camera that didn't adjust to the brightest object in the frame, which includes most security cameras.) This can take a fair amount of light. However, security camera optics usually suck, and due to low-res CCDs and low-quality and dirty lenses, even a few small light sources near your face can help over-expose and obscure your whole face. The light incident on the camera from a small IR LED is often more than sufficient to do this, especially if the camera has an exposure optimized for dark or indoor conditions. The extra light reflected from your skin due to wearing IR LEDs is unlikely to compare to the light emitted directly from the LEDs.

If you have any cheap cameras, you can text this yourself. A single small IR LED on a low quality IR-unfiltered camera looks like the lens flare from a JJ Abrams movie.
Sure, you need that end!

I've been to the post office twice this week to check a po box, and both times I didn't notice any security cameras in the lobby. I'm surprised there aren't any, and it'd be perfectly normal and natural to have them installed without people thinking anything suspicious. Most people would just assume they are there for security. To me that seems a lot better and less likely to arouse suspicion than some secret camera nonsense.
Really cool, I'll give it a try soon!
A similar effort of introducing math/figures/refs into markdown is the `softcover markdown` syntax. It's basically markdown, with latex commands allowed:

https://raw.githubusercontent.com/softcover/softcover_book/m...

The beautiful idea in markdown is that it allows you to mix (non-container) HTML tags in with the .md and it just works. Softcover markdown is in the same vein, allowing the more readable markdown for main copy, and intermix LaTeX tags as required. Beautiful if you ask me. Or at least beautifuler than ```math ... ```math.

The "backward compatibility" of ScholarlyMarkdown with basic markdown is a cool feature as many tools/plarforms exist that "support" .md now, but to preview you'll still need something that renders the equations, so strictly speaking ScholarlyMarkdown is a new markup langauge.

Wow! Thats really expensive! Hard do access stuff often sparks creative ideas and solutions :) Keep on hacking!
There are multiple JVMs written in Java.

Besides the sibling post, JikesRVM is one of the most well known ones.
This is a fork because making these changes to pandoc itself needs a lot of consideration.

Internal referencing and attributes on figures are two things that are currently being discussed for pandoc. The discussion has been going on for quite a while though - hence people making forks.

That doesn't invalidate the scientific method, nor does it preclude having a best-known model that matches all the currently available experimental data. New data that invalidates a model will necessitate a new model, or a new model may come along with better predictive power.

And to use current rationalist terminology: any given scientific model has an associated probability estimate for being true, which is very close to but not equal to 1; any work built on top of that model will depend on the truth of the model; and invalidating a model in favor of a new one requires re-evaluating any work based on that model. The "giant shifts" you're referring to occur when a model lower down the stack, with a pile of things built on it, gets invalidated or replaced by a better model.

On a day-to-day basis, you don't typically re-evaluate the validity of Newtonian or relativistic physics. Most of us regularly use Newtonian models despite knowing that they don't exactly match how the universe works. And we know that relativistic models don't exactly match how the universe works either (notably on a very small scale), though we don't have better models yet that work on both small and large scales.

I created a similar thing for my personal website:

http://www.dllu.net/programming/dllup/

which handles math using svgtex instead of clientside MathJax for faster rendering. It also compiles to both html5 and LaTeX. However, dllup is overall less polished, missing some features (labelling equations, sections).
Respectfully, it is important to understand whether sort stability is as bug or not. Particularly since you seem to have experienced exceptions on Android, and assuming that the problem was in the sort stability may have mislead you.
Oh, yay, we can now get DOUBLE GC PAUSES!

But it works the other way, too. The soldiers might obey the current regime more faithfully (or at least more fearfully) if the government sits right behind their back and order them to murder people or be murdered themselves.

In any case, I seriously doubt any armed revolution would happen in Brazil anytime soon. It seems the nation has held popular presidential elections continuously since 1989. You can't persuade people to die on the street, when they can just wait four years and vote the man (or woman) out.

Most importantly is that many of those people shouting about the virtue of work are enjoying anti-work on the backs of those working harder than ever. I don't know if it's actually malicious, or just an echo chamber (there have been plenty of studies that show that the more money people have, the more they feel they deserve to be in the position they are [0] - this of course being a generalization and not an accusation of parent), but it certainly seems like a degree of Ostrich Syndrome when it comes to acknowledging how the efforts of many often benefit the few.

>From it, we derive some engineering discipline, which uses the theory to, essentially, make predictions about what will happen if we do this to that, with the property that, if the predictions hold true, we'll have something useful.

We actually use logic along with induction to get a lot of theories. The fact that it works is proved by the scientific method, not the other way around.
Cool application. I had read about FM-Indexes a little bit, I find succinct data structures fascinating. Reading up on the new BMI instructions [-1] and "interpolative coding".

I was wondering if something like, "ISDL: An Instruction Set Description Language for Retargetability" [0] would help? It would be fun to create a combinatoric instruction sequencer and then run them all in an attempt to find some sort of probabilistic heuristic about instruction costs and efficiencies. Something like FFTW, but it analyzes then entire universe of possibilities. Some of the research in synthesizing new instruction sets or operating on compressed instructions might attack the problem from the other side [1].

Stay Fresh!

Makes you wonder why it doesn't have an emulator built-in.

Hardware on a spectrum is very simple, one Z80 at 4Mhz, and a single asic doing video output. Sound is one bit, either on or off (cpu has to generate the waveforms). Super simple to emulate.

Screen layout was crazy though... 6kb monochrome framebuffer, split into 256x256 pixel 3rds (top, middle, bottom - 2kb each). Each horizontal line is 32 bytes one bit per pixel, first line is top of screen, second line in memory is line 8 on the screen, next is line 16, once you get to line 256 you are back up to row 1 on the screen...) Colour was an additional 768 byte block of memory, one byte per 8x8 screen pixels. One nibble for the foreground colour, one for background.

Makes me cry thinking about the time I wasted trying to write sprite functions in assembly.

Anyways once you have power, bluetooth, modest arm processor and a keyboard all you needs is your hdmi output hardware (and your emulator/loader software).
Maybe in the world of ubiquitous automation, those sorts of things won't actually be problems.

Then the dictator is missing the point.

A successful dictator is someone who can manipulate the masses of pedestrians to rush on the palace... to cheer the leader (and to stomp on whatever political enemy the dictator has). A dictator who has to hide from the people is a poor dictator, and the life expectancy of such a regime tend to be short.
Interesting to see this come up. I've been migrating a couple projects to babel, the emacs org-mode literate programming style. Starting with the hello-world of babel, my emacs config file.

Babel and Org have clunky syntax but the mode takes care of that. The combination isn't perfect but it's very powerful, in particular the ability to chain several languages together in flexible ways.

Coming up with more ways to combine pretty formatting with syntax highlighting is polishing a pretty smooth surface. I'm dreaming of a really slick syntax and operating environment, like babel if it wasn't tacked onto org. In the meantime, using what we have.
John MacFarlane (Pandoc’s author) is heavily committed to the Common Mark standardization effort of Markdown (in fact he’s the principal designer of the Common Mark spec).

Both Common Mark and Pandoc serve different purposes: the first is an initiative to counter fragmentation/balkanization of the Markdown ecosystem and in being so has to reckon with backward compatibility, consensus and adoption. The latter is a document conversion library, which, by design, needs to reckon with interchangeability between formats and may hence be hampered by the lowest common denominator as regards feature support. Internally, Pandoc keeps an Abstract Syntax Tree (accessible in json format), and defaults on its own flavour of Pandoc Markdown (featuring a Markdown superset of content element types).

Both the Common Mark community and John MacFarlane have made it clear their first and foremost focus is on standardization, not so much on extending the feature set. Yet, scholars and technical writers are in dire need for something more heavy-weight than the rather small set of features offered by Common Mark implementations or Pandoc Markdown. Hence the Scholarly Markdown initiative and the scholdoc reference implementation (Pandoc fork).

More on how Scholarly Markdown came about, can be read on the blog of one of it’s pacemakers, Martin Fenner; e.g. http://blog.martinfenner.org/2013/11/17/the-grammar-of-schol..., http://blogs.plos.org/mfenner/2012/12/18/additional-markdown...
This might be viable using Sass or Less, since they have support for variables, nested selectors, etc. Although I'm not really a front-end engineer, so I don't know exactly what would be involved.
It's all about what you say no to. For example, if it is something that will cause a lot of technical debt, as a developer, I push back until I get a concession where I have the opportunity to undo the damage afterwards. Otherwise the debt will increase stress, lower developer happiness, and potentially prevent the business from growing in the long term as developer retention becomes more difficult the longer it lasts.

If you're going to ask for something unreasonable from someone with domain expertise, expect to make a concession if you want it done since that person has a high likelihood of understanding the true costs of the request. It is all too common to see developers experience burnout from 60+ hour weeks in order to attempt to meet a deadline because managers were awful at planning.

I often take a more neutral stance through explaining that it would take [X] amount of time to build solid & tested pieces of functionality as designed, and then let the product managers assess the information to come to a decision to either scale back or if it is still pushed for, then push back for a concession. It doesn't have to be a Yes or No proposition, it is like bartering - you want to get to a mutual agreement so all parties are satisfied.

But now that we know it exists, you've doomed us all! You fiend!
Communist ethos? In seriously don't get the connection. The premise is uncontroversial, isn't it? Until we automated everything humans will have to do necessary work to sustain our livings and doing unnecessary work for the sake of keeping everyone busy is a dumb waste of resources. After that I really don't care. If someone is not into fairly sharing this necessary work, go for it, work long hours. I will happily work less and spend my time with stuff I love to do if you really want to do all the work. If you want to do work you don't like, I won't stop you. What am I missing?
Why not just use DCC?
It's really only "pi day" for a single country around the world that uses a notation that nobody else can understand (mediumUnit.smallestUnit.largestUnit).

I'm also surprised that US still uses two-digits for years, as in "3.14.15", I though the changes brought by on Y2K had been worldwide.
People who do this are simply bad people.
The way I see it, the main feature is being able to plug math formulas in, rather than formatting documents. It allows you to focus on your content (one feature of Markdown) while still being able to write mathematics.

It's way too heavy to easily move around on its own. Of course, my desk is an old, non-smooth finished wood desk, so there's no air-gliding on it.

That's mostly historical at this point - Gumbo passed a security review as of 0.9.1, has had several rounds of fuzz testing, and is used by a bunch of other libraries now. It's been struck out of the README at HEAD, though I think it was listed in several earlier versions' READMEs.

I've not had a cell phone for over 10 years, except for a period of time when my job wanted me on call, so they paid for a blackberry... even then however I very rarely used it except a way to check my email without having to get out my laptop.

In any case, I haven't found it inconvenient hardly at all, except in the occasional situation such as a car breakdown. I do find it inconvenient when traveling however, but I usually only travel once or twice a year so I usually just load some minutes onto an old tracphone for those occasions

It is not really a money issue for me because I could probably afford to stay up to date with the latest and greatest gadget if I wanted to, but it is more of a philosophical issue for me. It seems phones today are designed to command as much of your attention as possible, and it seems that most of the phone usage that I observe is not a necessity. There's nothing wrong with that per se, but I do believe it makes it more difficult to live a balanced life. It is essentially the same reason that I don't watch or pay for television and movies.

These days, I'm not even sure it is less convenient to live the way I do... with all of the security & surveillance issues that have been cropping up, I am glad that I have inadvertently sidestepped a lot of the issues that are being revealed.
Did anyone else think that the MS Robot was more interesting than the actual pull request?
Fight cultures are about establishing pecking orders, not about finishing someone off. The easiest way to find out if you are in a fight culture is to try fronting. If this gets you out of a fight, you are somewhere fairly normal, however if you are in a fight culture, you will be immediately jumped on by people who are overjoyed at finding somebody else who is up for a proper barney.

Nice site, well-designed; however, I do think it will face a chicken-and-egg type of problem unless you can scale very quickly though.
I've heard this is also true for Twitter and a few other social networking sites, so you could potentially tunnel your traffic through them too.

However, these tunnels are going to be relatively low-bandwidth (especially if they start throttling it) and high-latency, so the "unlimited" would in reality be "how much can you transfer continuously in a month?"
If you want to write scientific documents with markdown, beware that pandoc already supports inline TeX (math with $$ and TeX commands starting with \) when doing md -> latex conversion. That has been my setup for quite some time.

'No matter how much “karate” you know, someone else will always know more.'

As stated, there is always at least one person for whom this is not true. However, even for such a person it is likely the case that there are still people who know things they don't, and the rest of 3 continues to hold:

The standard of living we all enjoy today is due to billions of people doing things they consider work and not "antiwork".

If we can live in a world like ours where everyone is doing "antiwork" instead of work, that would certainly be better. But it's not at all clear from this article how such a world would function.
