I wonder if you could include all keystrokes like Ctrl-x in the screencast, maybe even a timeline of the keystrokes; I imagined it to be "running" along the screen like in Guitar hero. Nevertheless this is a great effort in distributing latent/implicit knowledge, which I think coding to be heavy on; for example, how would a terminal user know that Ctrl-R is reverse-search? (don't get me started on finding out about going back to a previous match...) I remember how I found out about Tab by accident... While being ignorant of these epistemes are not barriers, they do slow down/kills joy.
This to me is one of the fundamental problems (or challenges) of smart contracts - they remove humans and human judgment from the core, but they just push it to the edges.

You still end up trusting a human - an "oracle". You trust the weather feed, or you trust some exchange to give you the accurate price of some other asset. If that oracle is mistaken (bug, intentional misinformation), the smart contract can be manipulated.
Except the range of possibilities isn't ['works', 'doesn't work']. Rather, it's ['works', 'no effect', 'harmful', 'works and is harmful at the same time'].

A banal example: proton pump inhibitor drugs used to treat acid reflux will, over very long timeframes, cause nutrient malabsorption resulting in more brittle bones. They also have what's called a rebound effect, where dropping them cold turkey leads to a huge jump in stomach acid production and worsening of symptoms. So while effective to reduce stomach acidity, they also have long-term negative effects and a sort of withdrawal that makes the original problem worse. It's a weird and complicated situation, and certainly not the most intense example.
Aka, the status quo before AWS allowed you to dynamically scale certain parts of your infrastructure. It's not perfect for all parts of your stack, but do you have a better alternative for databases?
Literally everything I read about Ethereum that's written by Vitalik stinks of something I haven't been able to put my finger on. "Sokal-ish" nails it exactly. The writing is never straight-forward, and always appeals to mainstream idealogical preconceptions. It's liberally salted with economical-jibberish-nonsense that sounds good as well.

I believe blockchain technology is important and I think Ethereum is a strong contribution in its own right. But the more I read of Vitalik's Sokal-style writing the more I wish he would stop and let others handle it because he is making it sound like he's going to scam the shit out of everybody.
Halve the intensity for the next 6 months - you are probably just very unfit.

Or alternatively you are under a lot of stress - again cut back on the intensity and volume.
I read about it in the newspaper for the small town my parents live in, and I have a completely non-technical friend duped into a weird Bitcoin ponzi scheme. It's getting there.
ViaGen Pet Cloning Company
I'm sure you're only partly joking, but sadly it does seem to be one of the biggest first uses. Oh and lotteries - those are popular.

On the other hand, people will continue to run ponzi schemes as long as there are greedy/ignorant people to attract, so it might as well be done all visibly. At least then the guy running the ponzi can't just tell everyone "sorry, feds raided the bank, all the money is gone" when he actually just moved it offshore.
Leaks in general are not illegal.

Politicians leak things deliberately all the time. They get to call their leaks things like "trial balloons". The process is almost entirely sanctioned by the press, which refers to them with phrases like "an unnamed source close to the president".

Staff leak things too, including by accident. At the bar, "Did you hear the great fishing story Senator X told Senator Y in the meeting today?" could be a leak that X and Y had a meeting.

Improper disclosing of classified information is illegal. I think that's what you meant to say.

A fake leak could be an example of black propaganda. https://en.wikipedia.org/wiki/Black_propaganda . It may or may not be illegal, depending on what it contains. Slanderous fake leaks like http://www.snopes.com/mcnatt-racist-memo/ could result in civil prosecution.

In almost all cases it's likely covered under the 1st amendment. For example, Jessup's description of the purported Philadelphia Experiment is a false leak about a secret military project, but clearly covered under freedom of speech.
The world's first solar-powered train
File storage: Swarm, and several other file storage protocols getting integrated with Ethereum.

Computation: pretty much the whole point of the Ethereum VM, plus there are a couple projects that put proofs on the blockchain of larger computations than the blockchain can handle.

Prediction markets: Gnosis and Augur

Efficiency: at least developer efficiency, in my experience

Economic layer: because you have reliable currencies on the network, both ETH and roll-your-own.

It might sound like buzzwords but at this point it's all real code.
The website seems like pure marketing at this point in time. Account created today, with every post promoting the company.
I only looked at it briefly. Very cool idea: Is it practical for heavy compute jobs though? Suppose a rendering takes 10 hours. If I don't know where the bug/difference is and just binary-search it, then they have to run at least 5 hours of computation to verify (out of the 2^^48 instructions, I'll start by asking for the 2^47th step).

I guess that's solvable by requiring payment for verification runs and just splitting up your work into much smaller pieces.
That only affects the newer ones the ones even the phantom 3 basic can be flown without the app.

Also it's not that the registration is tied to a government issues ID at this point.

I have had a bad experience with an algorthmic topcoder.

The guy has a brilliant mind. But he doesn't understand the big picture or why his code would fail when integrated with big codebases.

He thinks his work is "done" when he has written his tiny little code with some queues and trees. Then he leaves it for someone else to integrate and thus really solve the problem.

The best engineers I found were the ones who took ownership of their projects and had the ethic to dig deep. Not the ones who could solve toy algo problems.
I hear that on every topic and have never found it justified. A high level explanation can illustrate the general structure of what you're explaining and then you can paint in details as necessary. It's always possible to find an "in between".

When I wrote understandingbitcoin.us, I explained it as a global ledger with mutiple versions floating around where everyone agrees to trust the version (out of the valid ones) with the most proven work invested in it. That provides the overall structure and allows me to dive into:

- How you sign transactions (public key crypto basics)

- How you know how much work has been invested in something (the guessing game and the crypto version with hashes and nonces)

- Why people invest work in it all (mining and transaction fees).

- Why people agree to follow these rules at all (dynamics that encourage people to follow vs reject a protocol and what effects that has for the network)

(I would like to see something similar for ethereum.)

If I were explaining the internet to someone in your example, I would explain what functions computers can perform, then introduce the concept of them communicating with each other and what that allows, and the flesh out the details of how the communication happens in a distributed way.

(The linked page also doesn't provide that kind of explanation.)
Does the internal charge back model for Dynamo work the same as it does for AWS customers?

If I understand the author's point, you _can_ get great performance, but it requires over provisioning. So it's not so much a technical failing as much as it is a poor monetisation of the capability.

I see that elsewhere in AWS: They require huge instance types for large EBS volumes with ES. For our workload, said instances barely break a sweat.

No offense but that sounds a bit terrifying.
Even if you override the natural instincts, you have to replace them with some other form of behavior. There is no ideal set of behaviors, unless you strip all humanity from a species.

Once you overcome the 'hurdle' of 'undesirable' behaviors, you just adopt a new set of behaviors, which could be, in the long run, just as detrimental as the ones we have now.

I think Brave New World describes this quite well. The world where everyone is happy isn't necessarily the one that wouldn't be shocking to us in its behavioral patterns.
There are several languages that compile to the EVM. Also there's a somewhat speculative project to transition to a restricted version of WASM, which would let languages like C and Rust be compiled into smart contracts on Ethereum.
You don't need them all to work together. You just need one federated one that is functionally better.

It seems to me that a big problem is avoiding feature creep. I don't want or need a full browser experience for everything because it will break any customization I have set up.
How so?

The effect of DRM is to prevent the user from doing things that would otherwise be technically possible, such as copying. Once the software has decrypted the media, it can do whatever it wants with it. It is just so designed that what it wants to do with it is not the same as whatever the user wants to do with it.

Free or open-source software give the right and the ability to the user to modify what the software does. So if a feature is missing (save a backup copy), the user can add it (or pay someone to).

I piece of software cannot at the same time:
* be able to decrypt a video
* be able to be changed at the users' will
* be prevented from doing certain things the user wants.

If you merely write a piece of open-source software that lacks the ability to save a copy, you merely have a missing feature that can be added by anyone who wants to fork it, you are not preventing copying.

If the decryption is done in hardware, the problem is the same, just shifted. If people have the ability to change the hardware, then we're back to square one, and if they don't, then it's not a free/open-source system.
Classy. I've seen too many situations where the old man wouldn't die or relinquish power but also wouldn't contribute anything but obstruction. There should really be more of a mentorship model rather than the assumption that a director will be around indefinitely.

Ever heard about Casascius coins? Gold + BTC... there are physical coins with 1k BTC (~$2.5M) inside

https://en.bitcoin.it/wiki/Casascius_physical_bitcoins
I think I wouldn't assume that, myself; at least not after my stint in VietMWare (PTSD from a prior vSphere/vSAN experience)

We had VMTurbo/Turbonomic and VMWare's internal DRS that would sometimes compete against each other to decide where VMs should be scheduled.

You could handle balancing from inside of k8s core, or not. All you need is to evict the pod on the over-provisioned node, and to arrange for provisioning of the replacement node before the original pod is fully evicted. It should be the same for Kubernetes, if I had to guess.
Why did you use MongoDB if your domain model wasn't suited ?

I just don't understand people who complain about a technology and say it is useless for all of these use cases when they couldn't even spend a few hours to do a Spike/POC or some basic data domain design. MongoDB has very clear documentation about what you should or shouldn't use it for.

MongoDB is unique in that it is one of the few document stores available today. So if you have use cases such as 360 Customer View or where you need to fetch a lot of nested information with a single id it is blisteringly fast.

If you have a relational data model than use a relational database.
Hey! I do this too on twitch.

I mostly stream myself doing algorithms though. Basically I do the Google Style interview questions, and almost run my stream like I am doing an actual interview.

The reality of the livecoding scene is that most "real life" coding is actually pretty boring to watch.

In order to be actually interesting, you have to be talking and explaining what you are doing the entire time. I am glad that other people out there are having success!

You are talking complete nonsense.

HBase, Cassandra, MongoDB, Riak, Couchbase etc all write through to disk with proper fsync flushes. And I've never heard of any database that has a model where it writes to a virtual file system - whatever that even means.

Please provide some specific examples.
Anyone know if the EFF plans to throw some of their weight behind this particular appeal?
As an alternative to landmines as an area-denial weapon, this is great. It's relatively simple to disarm (presuming you've added some sort of networking capability to receive control signals) and capable of far more targeted destruction while also being far more deadly.

But landmines are (fairly rightly so) generally recognized as being a war crime, and I'm not sure this is enough of an improvement.

The train only runs a return route of 3km on flat track. It looks as if the train is battery powered with the batteries being charged from solar panels both on the train and at the station. It seems unlikely that the train alone could hold enough solar panels to keep the batteries charged, even when factoring in time spent waiting at the station. Mains power can also assist in charging the batteries when solar is inadequate (which is possibly all of the time?).

This train was originally planned to be diesel powered but has now switched to electric, I'm guessing due to protest from the local community.

Second this or well third I have the 12/24/72 versions of this backpack (doubletap color scheme which is dark grey) and they are by far the best backpacks I've owned.

They are very convenient tons of storage space, everything is easily accessible, best back support I've seen outside of really high end trekking packs and they are durable as fuck.

I've had some expensive backpacks from the likes of samsonite, they look good but they tend to age very poorly (I might be abusing them too much) and they aren't nearly as comfortable to use at the 5.11 ones.

Please be specific. NoSQL comprises hundreds of different databases with very different semantics.

Technically PostgreSQL is a NoSQL database and it along with Cassandra for example have modes in which they are fully and atomically consistent.

I never was into sports but after high school I went to the gym and did for about 20 years. I got out of the habit when I started shift work and never got back except some cycling in the summer.

I miss the feeling after I pushed myself the warm feeling and the total relaxation no aches no stress. I hated the feeling of missing the gym I could feel the tendons in the back of my knees and crooks of my arms (inner elbow?) ache.

The problem was I never made any progress I must be what is called a non-responder. If I tried to do more I got tired and took more time off. Often I found I did better after taking a three or four days off.

But any exercise is like medicine you're only there you only exercise because you have to. I want to be active but not a march forced by the fear of death I want to be there because it's fun.
Exactly it is extremely unprofessional to do that when you see a co-worker for the first time, especially when they're only an intern and there's a major power difference
Yes, I think splitting up the work is a good idea.

The authors already thought about how to incentivize verification runs. It's really cool. Check out this informative podcast with some of the team members: https://youtu.be/QY0OUTaIWIc

A key word that had been disproven many times. The most recent example is Rust, which has a type checker that now type checks many previously unsafe C++ idioms. The other examples I listed are also quite practical, and have been used in high assurance systems.
I don't think this is really true.

Right now there are 300 live viewers watching people in twitch Game Dev.

And going to the website of liveedu.... well it is aweful hard to find a list of live streams ordered by number of currently active viewers. It almost seems like they are trying to hide the number of active viewers, perhaps because they are so low.

The closest thing that I found to a list of active live streamers shows me that there are 2 streams running right now, with a total of 15 users watch.

You can screengrab at the interface between the decoder in the monitor and the panel itself, using an LVDS capture card.

I believe they want to, but the appeals process is an untested one, and will be evaluated by the same people who made the original decision. Don't get your hopes too high.
It seems to me Frege understood the need in mathematics to talk about many different kinds of thing - numbers, truth-values, functions, and so forth - and to distinguish which kind of thing you are talking about; but not the necessity to use types (or other methods) to avoid circularity. Indeed, it is precisely the mistake Frege made in his attempt to axiomatise logic and mathematics and which led to Russell's paradox, that motivated Russell (and Whitehead)'s theories of types.

Frege certainly articulated a clear notion of what a function is, which is significant.
Amazon is limiting it to 5 operations per second per shard, not per customer. That is if you have 200 shards and 1000 write capacity.

It's a problem with how Amazon calculates your capacity units as it scales up Dynamo for you, if you have a particularly large data set with a few very active users.

I can see how that would work in smaller towns, but I just haven't seen that in LA--mostly because of sqft. The only exception is something luxurious in the 1920s is considered small today.

I was looking over all of the places I've rented since moving here 10+years ago. A studio built in 1947 (multi-unit apartment), 1br apartment built in 1961 (multi-unit apartment), 1br built in 1923 (house split into a triplex), 1br built in 1958 (multi-unit apartment).

When I was looking at buying houses in LA, one neighborhood I was looking at I was told most of them were middle-class Jewish workers in the textile industry when the houses were built in the 20s (I think). Eventually, they moved out east of LA for larger, cheaper housing. The 10 interstate was built, splitting the neighborhood in two and this was the seedy side. I guess that's an example of what you're talking about, there. Because of the train, the neighborhood was recovering and was already a bit much for me to afford.
I'm curious; what did you initially parse the sentence as meaning? I can't think of any other way to read it
