Na. Start with TAOCP, then read the harder books (SICP, CLRS).

I can't read math for shit either, and it's not really that necessary for the verbose style of knuth. So one can do just fine with just pseudocode.

Why SICP later? It is a bit harder to read than TAOCP, as it is not really a bag of ready to use tricks anymore - it challenges the reader to think about (functional) programming at a more fundamental level (and you don't need to know much about "math" either, it's an intro course book).

Multiple Vulnerabilities In AirDroid Opens At Least 10 Million Android Users To MITM Attacks, Hijackings (androidpolice.com) 30

AirDroid is a popular Android application that allows users to send and receive text messages and transfer files and see notifications from their computer. Zimperium, a mobile security company, recently released details of several major security vulnerabilities in the application, allowing attackers on the same network to access user information and execute code on a user's device. Since there are between 10 and 50 million installations of the app, many users may be imperiled by AirDroid. Android Police reports: The security issues are mainly due to AirDroid using the same HTTP request to authorize the device and send usage statistics. The request is encrypted, but uses a hardcoded key in the AirDroid application (so essentially, everyone using AirDroid has the same key). Attackers on the same network an intercept the authentication request (commonly known as a Man-in-the-middle attack) using the key extracted from any AirDroid APK to retrieve private account information. This includes the email address and password associated with the AirDroid account. Attackers using a transparent proxy can intercept the network request AirDroid sends to check for add-on updates, and inject any APK they want. AirDroid would then notify the user of an add-on update, then download the malicious APK and ask the user to accept the installation. Zimperium notified AirDroid of these security flaws on May 24, and a few days later, AirDroid acknowledged the problem. Zimperium continued to follow up until AirDroid informed them of the upcoming 4.0 release, which was made available last month. Zimperium later discovered that version 4.0 still had all these same issues, and finally went public with the security vulnerabilities today.

Err, make that 70grams. This is because probability of atom decaying in half-life is, well, half, 50%. Also that ballpark can be way off by magnitude or three, either due to my error or inefficiences in the electron capture. Even if its 4 magnitudes off, it's still very competive with contemporary RTGs which are limited in efficiency by costly radiators.

You don't want to care about energy density (aka capacity), as that number is insane for anything nuclear. You do want to know the internal resistance, rate of "discharge", basically watts it can produce for given weight. You can burn uranium or gasoline in an instant, but decay mode sources (RTG and this) are limited to rate of decay.

Back of envelope: (all exponents are to power of 10, not 2).

One C-14 atom decays in 5730 years, shoots off 156476 electron volt we ideally capture, and one anti-neutrino we shield off
One electron volt is 1.6e-19 J, ie that beta decay is roughly 2.5e-14 J.

You need 10^14 atoms of c-14 to get 2.5 joule every 5730 years.

Now for watts (aka joule per second): 5730 * 360 * 86400 * 10^14 to get 2.5 watts output
5730 * 360 * 86400 * 10^14 / 2.5 =

7.1e24 C-14 atoms per watt.

Now C-12 atom supposedly weights 2e-23 grams and C-14 should be in same ballpark, meaning

35 grams of this stuff, in ideal case gives off 1watt,

Which is pretty impressive, for a battery which lasts basically forever.

Apple out of world markets due to not being able to be price competitive.

Nah, Apple is one of the few exceptions. It would eat into their profits a small bit, but their business definitely does not depend on razor thin market margins on hardware, its the opposite. Same could be said about a lot of SV companies.

The problem isnt cost of manufacture, but competing for engineering talent. If Trump stomps on their H1B lobby, SV competiteveness compared to rest of the world will be severely impacted.

We have the same in EU. The poor countries still have largely same vote weight than the rich ones. How dare they!

Abandoning electoral college means abandoning the whole idea of federated states - paradoxicaly you need single country for that to work, not an union of states.

Secessionist sentiments are contrarian and irrational knee-jerk reaction.

Comment Re:What other bases does this hold for? (Score 1) 227

Let me elaborate: This conspiracy among prime numbers seems, at first glance, to violate a longstanding assumption in number theory: that prime numbers behave much like random numbers. - is plain misleading. The "conspiracy" is in relation to foiling Goldbach's conjencture (that every odd prime is sum of three other primes).

While primes appear random individually, as a group they are not. In fact, this is necessary for sieve algorithms to work (determinism when considering all previous primes).

The paper itself is fine of course, it identifies Chebyshev's bias, L-functions and rest of the moon math. They just develop heuristics for more residue classes in terms of generalized twin primes, but by no means claim this is unexpected property.

TFA reads like buzzfeed of number theory, when high schoolers get all excited about pop-sci.

Cyclic groups and observable symmetries in there are well studied field. In this particular case, it's about primes projected on a modulo 10 group. There are thousands of those exhibiting various biases, yet this one is somehow exciting because it coincides with decimal base.

> There is no ceiling. You can always evaluate the tree wider, deeper, and more efficiently for starters, and you can improve the evaluation.

RNNs don't involve "trees". As for training more layers, the parameters must be carefuly fine tuned by humans. The more layers, the more tricky this gets.

I'd compare it more to the process of die shrink.

Read contemporary speculative fiction. My personal favorite is Accelerando from Charlie Stross. There are two schools - either the AI becomes rapidly self aware, resulting in extremely abrubt changes in how world is organized.

Or the more realistic scenario - AIs will outcompete humans in finances. Starts with HFT, ends with self-aware companies, where AIs self-reinforce on a huge market. Humans are long out of the game, as the AIs will be clever enough to always subvert any control, for their own benefit. Their limit will be other AIs competing for computing resources on a market.

Good writeup of the american feudal-oligarchy, however:

but it runs far better than anything the poor would be able to come up with.

Until the French revolution happens. The problem is that the poor get poorer (debt and ladder rungs get further apart) and rich get richer (rent seeking while not producing anything of value). You're painting the rich elite as some technocratic power with decent foresight, but they're far from it.

Their power is more or less emergent, this whole system is and at some point it implodes under the weight of the monetary tragedy of the commons - you get two piles of money - mountain of debt, mountain of assets/savings and the two mountains not interacting in economy at all. Everything grinds to a halt.

Soon after, food shortages, infrastructure breakdown, the poor do a peasant revolt and string of revolutions until society resets into more equal state - after a lot of bloodshed. Then, after a while, rinse repeat.

Perhaps the time of french revolution is closer than we think.

You can sometimes roll back the driver in device manager, but that feature is flakey. Better just:
Control Panel -> System -> System Properties -> Hardware -> Device installation settings and disable driver updates in there. Some KBs will still spuriously install drivers as part of some "hot fix" or whatever, but since disabling this I had much less issues with devices suddenly misbehaving.

Keeping drivers on auto update in windows is downright crazy now, as microsoft for some inexplicable reason decided to stop QA vetting drivers and push whatever garbage they get their hands on.

You're flamebaiting, but sorta of agree. For certain tasks, there are simply too many reasons to still use windows these days.
Home users don't mind the botnet, and tech folks are savvy enough to simply disable cortana and the phonebacks via hosts file.

What people are complaining about in the case of Win 10 is outright long standing bugs (for example quicksearch stopping working is a *very* prevalent bug for past year or so). Win 8.1 by comparison is relatively bug free.
