The post you're replying to does list compensating transactions (a form of rollback)

One gotcha that is not covered by Sagas (I could be wrong) is when one or many of the network paths involved in the distributed tx become unreachable (network partition event) and you have no idea of the state of that part of the tx. Do you re-try that part and risk sending the same instruction twice (ok in some cases but not all) vs risk of having sent no instruction? If I had to implement a distributed tx I would first verify my mental model using TLA+ and use a (persistent) transactional messaging system with at-least-once delivery as the backbone, and make other accommodations for such scenarios.

Depression is diagnosed based on clinical symptoms, not brain chemistry. Read the list of symptoms from the DSM V and compare- "chronic ennui" as defined in the article would get you most of the way there.

COM brings back a lot of fantastic old memories.

When I was a kid, I used to make VB6 applications, and I'd be able to get custom widgets from the Internet, and import them into my VB6 project seamlessly. It was truly amazing, and mind-expanding.

The JS/React/etc web ecosystem doesn't come anywhere close, in terms of the ease-of-use that VB6 had.

Agreed 100%. The product, as best as I grok it, is totally garbage. But, that wasn't what was being said. What was being said was "Urbit is Nazi trash" and "Ubrit is feudal in nature and therefore bad". This kind of totalitarian thought policing is what is bad.

The nature of Reddit is very much so Feudal in all the same senses as Urbit except that Urbit is much more explicitly limited in the number of polities that can be created. Subreddits are inherently feudal in the exact same way in that some set of lords (moderators) have control over what happens in their domain (subreddit). Who can become a lord (redditors with X amount of Karma) is limited and so are subreddits, thought the limit is so large it's not really a practical limit. The principals are the same, still, so arguing against Urbit for being bad because of this nature is mostly if not entirely wrong. The reality is these arguments are more about moralizing than the actuality of what is presented.
I second this. To OP, background checks are often a lot less comprehensive than you think.

And how long have you been an engineer? And how did you prep? Would be a dream for me to get a job there one day.
Apollo 8 and 10 both went to the moon without landing, doing that on a multiple year mission does seem wasteful. However, there are a host of things to test.

From an engineering perspective going to mars orbit means far less sunlight which means a host of new problems. An engine and fuel system to get there would be new and could also be used to send a lander for future missions.

IMO, the Moon might be closer, but Mars is a much better target for long term colonization due to an atmosphere, shorter day, higher gravity, etc.
re. 3), are you kidding me?

Anomaly Detection as a Foundation of Autonomous Monitoring
Yes, it does... something similar enough.

Accounting has been doing that for centuries already, so it's not new by any means. It's also not free, it imposes severe restrictions on your system's architecture and the kinds of problems it can solve.

> the social networks that universities provide students and alumni are valuable

Colleges say this, but does anybody ever really find it to be the case? I suppose if you went to Harvard or Princeton this might be true, but as a representative of the other 90%, I've never interacted with anybody I went to school with (including a year abroad, a four-year degree, and a master's degree) in any way.
Also dropping from search appearance, maybe that's why they changed the beta.
When people ask why the stock market isn't in the dumps when it feels like the whole economy is stopped, this is why. Small business isn't on the S&P, and out of the businesses in it, a large percentage of the market value is concentrated on the tech giants who aren't getting nearly as affected by the current crisis as everyone else. If they don't actually benefit from it. Still super impressive results.
This is spot on. I'd add to it this way:

Humans have not been successful in identifying an explicit objective function for society and then building social, political and economic mechanisms to support/enforce those. We point to the Former Soviet Union, Great Leap forward etc... as failed experiments in authoritarian enforcement of an objective function.

As a result we have defaulted to the random walk and iterative nature of capital markets as the way of communicating, aggregating and forecasting individual objective functions into a collective function.

It's clear however that, for a lot of reasons, this system optimizes for short term rewards and not for long term planning.

That would make sense, since in effect the system is aggregating short time horizons and lack of capacity to plan long term. It's also fairly easy to hack parts of the system (marketing, arbitrage etc) for individual gain.
I wonder what amazon’s report is going to look like. Only half an hour until they release
In California, at least, it used to be that(still may be, but my data is a couple years old) you could get about 2 years of your prerequisites done at a community college and then use that to funnel into the Cal-State schools.

That was a significantly cheaper option for most students. And the classes tended to be smaller and, often, much better quality.
That's what they called "going native" (vs. using .NET).
I don't see Microsoft doing much EEE on their modern non-cost-centre platform (Azure), though. Amazon is a much clearer example these days, with AWS having "embraced and extended" Postgres into Aurora, Redis into ElastiCache, and many other examples. (I don't know if AWS has ever gone all the way and "extinguished" any of the cores they've built upon, though?)
IANAL, but it strikes me as pretty obvious that the owner of the NN is the owner of the copyright on any works created by the NN with the important qualification that training the NN on works copyrighted by others could possibly be considered by the courts to be infringement.

If you need some visualization going beyond ASCII characters, I co-developed bra-ket-vue, a quantum state & matrix visualizer in Vue.js. A working demo here:

It uses a different engine https://github.com/Quantum-Game/quantum-tensors, supporting arbitrary quantum states, not only qubits.
ACH is only a thing in the United States with our garbage-fire banking system though. In most countries you can do person-to-person transfers instantly with almost no fees. This is a non-issue for most people and crypto is solving it poorly.
Good eyes, I definitely glossed over the linkage in the parent article. Nice stance they're taking with all the transparency about their decisions. Pretty level headed public response.

It may be free but fewer people attend university in European countries (apart from wealthy Luxembourg) than in the US. So essentially, the “free” university is a tax on everyone that mostly benefits the rich. I don’t think Americans want that.

And part of the problem with asking "what's the best lecture on x" is that the replies often come from people who have seen one prestigious lecture, and recommend the one they are familiar with. Popularity breeds popularity. There's a much smaller sample of people who sat through 20-30 of the same lecture series, for the same course, from different professors, and know which parts are the best from which person.
It seems clear to me that they have no interest in targeting average consumers at this point.
The Intel x86 Microarchitectures Map [pdf]

It's probably a mix. Plenty of people have children and want to provide them a safe and strong launchpad, and "cut back hours and enjoy life" won't do that. Consumption and status symbols are part of the game, though I don't think it's really a question of buying a new car every few years for average people, that's out of reach for a large part of society.

You don't need to play the game, but being inside the game also provides security. Humans are very social, the odd outlier that prefers his own company and is happy to trade comfort and safety for simplicity and freedom really is an exception.
> William Shakespeare is widely regarded as one of the greatest authors of all time and one of the most important and influential people who has ever lived.

I see some hype just there. Is there any study on what the world will look without William Shakespeare influence? Or it is Shakespeare so famous like the Mona Lisa is (It has its merits and place in history, but, not the one that the press has given)?

> An online exhibition, due to be made available in early May 2020, presents 3D-scanned artefacts recovered at the site of New Place. These objects, some of which may have belonged to Shakespeare, have been chosen to characterise the chronological development and activities undertaken at the site.

A part of the voyeuristic and quays-religious approach to the exhibition, the increased interest in archeology that this kind of projects can create is welcome. As, much as I am skeptical about the trendy obsession on certain authors or pieces of art, the general public awareness and funding for high-tech 16th Century archeological techniques is welcome. It is not the first time that spectacle and science empower each other, and I hope that is not the last one if we want the science to keep rolling.

I understood from the start that this data was for fraud protection. At the time of my initial article, Stripe had not clearly disclosed the extent of their tracking nor stated any limitations on how they would use the data. I tried hard to avoid accusing Stripe of nefarious behavior, so if there are specific sections in my post that failed to do this, please let me know.

Regardless of Stripe's intentions, I believe there needs to be clear agreement about what data Stripe collects and what limits they'll observe in using that data. If we blindly allow Stripe to collect whatever data their JS library has access to as long as their intentions are good, we put ourselves at risk if that data falls into the wrong hands.

I think Stripe shows a serious commitment to privacy and security, but there's always an inherent risk in storing copies of data with a third party. The more data that Stripe collects, the greater that risk, so clients should have a say in whether that increase in risk is worth the improvement they receive in the accuracy of Stripe's fraud protection.
For anyone curious about how "good" the camera is: with the lens they sell it's about as good for still pictures as a modern phone. Somewhat worse for video, depending on your application, due to stabilization, software, and the 2-lane interface.

More specifically, the sensor is a Sony IMX477, slightly better than the IMX377 featured in the Nexus 6P, Nexus 5X, HTC 10, and Mavic Pro drone.

Pretty nice, for $50 in a neat little package. This kind of thing is usually a good bit more expensive.
The kind of knowledge you need to evaluate this is something that is normally taught in college. What high school teaches decision making under uncertainty, along with economic history and statistics?

I mean sure we could try to teach kids this stuff, and I certainly aim to tech my kids, but it's not what's been done in the past at secondary school.

Or is there any explanation how Space Ships are supposed to land? Thanks Thanks
IF... and I stress IF ETH 2.0's sharded blockchain system works then we'll see a 64x increase (from 64 shards) in throughput on launch with a roadmap to scale to 1000 shards.

The gist of it is you have a "multi core blockchain" that is only verified by a randomly chosen subset of validators that then sync their state back up to an oversight chain called the beacon chain.

Not sure, but of the 44,965 being spent per student, only 7,219 is going to salaries and wages of the instructors (2016-17). Seems like an awful lot of overhead in there somewhere.
> You don't have to do 100% of your finance on blockchain. I like the freedom of knowing that my funds cannot be controlled by any third party entity, who may object to my spending on the basis of some arbitrary criteria. We've seen people shut out of PayPal for very arbitrary reasons. We've seen the marijuana industry in Colorado shut out of banking (https://www.acams.org/aml-white-paper-marijuana/).

See, I see Crypto people mostly arguing that Crypto is going to take over a some huge percentage of transactions in order to justify some skyhigh valuation, and then when pushed back on whether it is actually superior for large percentages of transactions, they revert back to an argument that there are certain (normally politically motivated) transactions that its important for.

Unfortunately I don't see a universe where you can justify any of the valuations or importance of Crypto if the main use is the much smaller set of transactions.

The bank doesn't want the bet because "bankruptcy" means very different things to the bank and to the student. To the bank it means they lose all their money. For a just-graduated person with minimal assets it's not that bad -- sure you can't get a mortgage to buy a house for a while, but you probably couldn't have afforded that anyway with student loans. You still have the degree, they can't take that (well, https://www.jefftk.com/p/repossessing-degrees).
I think that "Absolutely do not bring it up" may not be the right policy. OP really should talk to an employment lawyer.

Note our cheap goodhire background checks scan an approximately 5 page list of courts. We are required to do this by various certifications such as soc2, etc.

I would carefully think through bringing it up with the hiring manager. First, because if I were the hiring manager, I'd be much happier if a candidate told me. That way I can think through if this matters for the position or not, and be in a better position to handle internal messaging. The second benefit is it allows OP to control the messaging (I was young / I am an animal rights activist and potential future employer doesn't do animal experimentation / I've changed, etc). If OP doesn't proactively bring it up, OP's future is being decided in a discussion between HR and the hiring manager with zero input from OP.

Kernel function is simple - Are you in a high dimensional space? If so, choose linear kernel. Else? Choose the most non-linear one you can (usually a guassian or RBF). I suppose quadratic and the other kernals are useful if what your modeling looks like that but in practice that is rare.

Prediction is not that slow with linear SVMs especially not compared to something like K-NN. The main hyperparamaters which matter are the "C" value and maybe class weights if you have recall or precision requirements. The C value is something that should be grid-searched, but you might as well be grid-searching everything that matters on every ML algorithm and in this regard SVMs are fast to iterate over (because the C value is all that matters).

Applying categorical and continuous features is not difficult if you choose to do it in anything more sophisticated than sklearn. Also, pd.get_dummies() exists (though it may lead to that slow prediction you're concerned about)

You're most likely right with GBM or Random Forests - though they can have all sorts of issues with parallelism if you're not on the right kind of system. You talk about linear models but SVMs are usually using linear kernals anyway and are a generalization of linear models (including lasso and ridge regression models).
> Nobody has abandoned their business or fled.

Curious where you are? Here just within walking distance in my neighborhood in Chicago there have already been "a lot" of local stores announcing permanent closures. If I had to estimate, something around 5-10% so far out of a couple hundred. But it's only April, and I fully expect most who are not re-opening to have either not realized it or not announced it yet.

I also expect quite a number to re-open their doors only to be disappointed with 25% of their usual business. Conservative "boring" businesses I expect to survive for the most part (e.g. family owned laundromat), but anything in the niche retail or food and beverage sector I suspect will be at extremely high risk of going under very quickly.

Landlords here are also not (at least from my limited network of business owners I'm friendly with) reducing or forgiving rent. The most I've heard of anyone getting is a forbearance where they simply tack on the extra months to the end of their lease, which certainly is better than nothing but not exactly forgiveness.

Also if you pay attention to used commercial equipment markets, the markets are so far signaling a massive glut of used equipment coming into the pipeline via business liquidators. And this all just started in earnest this month. I suppose good for me in a sense since I've been really lusting over a commercial-grade deli slicer, but the massive impact it's already having on small businesses is quite sobering to me.

Jack Vance's scifi/fantasy classic "The Eyes of the Overworld" starts with a quest which has the protagonist steal magical eye glasses which make the denizens of a village who literally live drenched in shit and mud and eat garbage believe they are lords and ladies living in palaces and eating the most delicious foods.

They know it's not the truth, but for all intents and purposes, while wearing the magical eyeglasses it becomes the truth.

The rest of the book is hilarious and I fully recommend it.

> The bigger problem for the parent commenter is if actual game logic is executing on the server, which is probably the case for online multiplayer games.

Yes. I used to play on unofficial MMORPG servers back in the day. People reverse-engineered the network protocol and created an open source game server. It didn't have all the features of the official game but it ran fine and could be freely modded. I used to host one of these on my own home computer... Traditionally the official game client is used but some games even have custom clients!
