Most recommendation systems today are multi-sided, with multiple stakeholders. Consequently, the systems need to optimize for catering to various stakeholders (ex: consider uber eats, where you have the eaters, delivery partners & restaurant partners - each with a different set of expectations from the platform.) - Find out how these systems are designed, optimized and explore the inner workings.

In this First Part, we actually begin by explaining the Problem statement, setting up background on common patterns of building recommendation systems in the industry today, methods of developing ranking models (LTR), and popular metrics to evaluate ranking models & then introduce various approaches to multiple objective optimizations applied to recommendation systems, and dive a bit into some examples from Etsy, Linkedin & Expedia to understand how this is solved in practice.

In the upcoming posts, we will expand on this subject in more detail, on various types of multi-objective optimization methods.

Check this out, and let us know if you find something missing here or would like to be covered or maybe suggest improvements.

Why do you want to avoid a lawsuit? Simply having a lawyer approach the employer with one might be enough for them to give you what they owe. And if not, they might have to cover the cost of the lawsuit too (though similar to what OP noted, this could depend on where you live, the suit filed, etc)
Foraging Complexity and the Evolution of Childhood
... fond old memories of replacing a dud 4K DRAM on a Vax 11/780, all on my own (the company I was working for was too cheap to pay for a DEC service contract).

Unfond, more recent memories of being asked by the Dell support tech to remove all the DIMMs in the server and start putting them back, one by one.

48 DIMMs. 15 minute BIOS boot time. Didn't even bother doing the math.

It was a better use of our time and money to mention "contractual four hour response time" and "We're about to send email to our corporate lawyer, do you want to reconsider your support response?"

Sure. And if you happen to actually venture into that low end of the stack, you learn. But the idea that you should know everything, just in case (or just because us olds had to learn it) is extremely wasteful.

I use a black box (car) to get around, and I'm fine with that. I didn't need to learn more than "change oil", "inflate tyres", "how to (dis)connect a battery". I'm good.

I use a black box (TV) to view my entertainment content. All I know is "cycle the power so it works again".

I treat my computers the same. Yes, I've built multipliers from individual transistors, and I've seen and used the blinkenlights, and I've written entire kernels and networking stacks: I don't need it much these days. And if I need it, guess what, there are still people who make it their business to know all the things, and I'm happy to give them money so they can figure things out. (Because most of that knowledge has collected dust by now)

We spend our mental capacity where it's needed. Not everything is equally important, and abstractions exist so not everybody has to learn everything. (I mean, you don't fab your own ICs either, do you?)

1. Demilitarize the police force. Stop with a Ranks, and organization structure that mirrors that of a military

2. Bring back sheriff;s instead of having police forces report to a mayor or other executives, the head of the police force should be an elected position accountable to the people

3. Expand open records laws to include policy manuals for every police force, and create a Citizen Review Board that can have no more than 1 retired or former police officer, judge or prosecutor on it. Today many "Citizen" review boards are filled with insiders of the force, retired cops, family members, prosecutors,etc

4. Mandatory body camera's for all public interactions with at most a 3 strike policy where if the officer fails to record an interaction more than 3 times they are terminated

5. End Qualified immunity

I've read enough Marx to know he had a layman's understanding of Economics. Read his own words:

https://www.marxists.org/archive/marx/works/1847/wage-labour...

>>But even if we assume that all who are directly forced out of employment by machinery, as well as all of the rising generation who were waiting for a chance of employment in the same branch of industry, do actually find some new employment – are we to believe that this new employment will pay as high wages as did the one they have lost? If it did, it would be in contradiction to the laws of political economy. We have seen how modern industry always tends to the substitution of the simpler and more subordinate employments for the higher and more complex ones. How, then, could a mass of workers thrown out of one branch of industry by machinery find refuge in another branch, unless they were to be paid more poorly? and

>>To sum up: the more productive capital grows, the more it extends the division of labour and the application of machinery; the more the division of labour and the application of machinery extend, the more does competition extend among the workers, the more do their wages shrink together.

This was proven wrong in his own lifetime as factory worker wages rapidly grew in industrializing Britain. This Luddite fallacy: that automation causes wages to decline, is something that laymen, who haven't studied Economics, believe. In reality, automation is the primary source of wage growth, and the reason wages today in the US are 20 times greater, after adjusting for inflation, than they were 200 years ago, in 1822.

And like I said, he didn't understand the basic fact that capital contributes value to the economy, and thus that profits accrued to business owners are not "economic rent", and that furthermore, capital does not emerge unless those who create it - by saving and investing - are compensated via ownership-rights and profits.

I suggest you study real Economics, and then analyze Marx' claims in light of what it teaches you.
If remember correctly, the [Howl editor](https://howl.io/about.html) has Lpeg and use of scintillua. It looks great and it's older but I'm not sure why Lite got more press coverage.
Ah, and I forgot to mention:

In 2011, when JAC Motors started to sell cars for cheaper, you saw what happened: government raised taxes over imported cars (maybe a result of a lobby from the other manufacturers?)

That's what happens when 1 manufacturer decides to sell cars for a fair price here.

The pay is decent if you get promoted once or twice, however the pension is often incredible. Retire at 48-53, receive 80-90% of your top-grossing years for the rest of your life, with all the overtime/holidays you can accrue factored into the calculation, meanwhile as a 25-year veteran you can easily get hired as some company's head of security for 6-figures all while collecting that pension and gold-plated health benefits.

While I agree that the weapons, armor, and technology generally given to police is not appropriate (especially at small town levels, vs county sheriff, swat.. etc), trying to label them as a paramilitary organization is only going to result in eyes rolling. "Recognizing" them as such is probably not the right place to start, if you're serious in trying to convince a larger swath of the population they need to be fixed.

I see two defects in your reasoning.

First, our understanding of what constitutes physical violence is relatively reliable. Whereas our understanding of what constitutes misinformation is relatively unreliable. Therefore any comprehensive dictatorship of information would be relatively extremely more disastrous.

Second, misinformation is self-limiting in its effects. If it is misinformation then those who consume and communicate it will be relatively weak and disorganized. Whereas those who consume and communicate good information will be relatively strong and organized.

The present state of the mob versus the corporation is a clear example of that. The mob has the numbers but nevertheless, the corporation wins. Because the corporation is organized and the mob is disorganized.

I've learned that every time I'm near a city center and my phone loses connection or gets very slow, there's a little "5G" showing in the status bar.

Sometimes I'm able to mess with the network settings to turn off 5G and go back to 4G, and then my phone works fine again.
I don't really know what I'm looking at here, but it feels very sci-fi and I'm into it.

I don’t have any advice about getting help from WhatsApp. I don’t even use it.

You have described a single point of failure — part of your critical workflow that can bring you or your business to a standstill. The usual advice comes down to eliminating SPFs and/or maintaining redundant copies.

In my opinion no one (and no business) should rely on free third-party services such as Facebook or WhatsApp to run their business. If you do you have one or more points of failure completely out of your control, with no recourse, and vendors who have no incentive to fix the problem. I know it does you no good now to hear this but you can make changes to prevent it happening again.
Use the venerable GNU Nano editor on the terminal.

You can get it easily via gitbash (https://gitforwindows.org), or WSL, or cygwin or ... dunno.

You can also try compiling it for windows directly. Nano provides some Win32-specific stuff on its website (https://www.nano-editor.org/dist/win32-support/), but I haven't tried them, since nano through gitbash worked fine whenever I've needed it.

You have to write to the SQLite via the rqlite HTTP API but it will replicate the data to N nodes (at least 20) via RAFT and then others can read-only the SQLite replica files directly; and file-permissions prevent the accidental write.

Misleading headline.

Oh man no one cares any more. They fudge through it slowly when there's a problem and forget about it immediately. I've seen teams waste 3 months unable to fix a simple issue and I've walked in and seen it right away. Can I pass these skills on? No because no one gives a fuck. And quite frankly my soul died enough that I don't either. Just over 5000 days until I'm retired.
Fortunately, in California the local politicians have had the power to deny homes taken away from them. The process began yesterday in Santa Monica, where developers automatically obtained permission to build over 4,000 units because Santa Monica's housing element is noncompliant.

San Francisco's housing element should fall out of compliance in early 2023, making it possible to build things without dealing with the local housing cartel.

Jobs with power attract people who like exploiting such power.

And it's a particular character flaw that makes them think they'd get away with it, even though they tell others. That's also a reason why police officers like to make inappropriate racist or sexist jokes: It's relatively harmless but by the reaction they can evaluate which colleagues would back them up.
I would argue its an acquired smell, much like beer is an acquired taste.
>How does your configuration where the balls where near one corner in the cube causes mercury to rise to a different level than the configuration where they occupy a larger volume near the center?

The balls have to touch thermometer. Otherwise the thermometer observes nothing. Deriving the exact formula of this interaction is complex but the intuition makes sense.

Interaction with the thermometer at a certain energy level produces a macrostate at Temperature T that is high probability. You see this macrostate throughout your lifetime. But nothing precludes the low probability macrostate (where all balls are at another corner of the box) from occuring. It's just that microstate has such a low probability of occuring you never see it. When nothing touches the thermometer, that temperature reading is the absolute zero macrostate.

>Apparently you say that the entropy increases because the macrostate changes. But the macrostate is undefined until the balls hit the thermometer. But the entropy has to increase for the balls to move. It’s all a bit confusing, don’t you think?

No. The macrostate is never undefined. I defined it as the measurement on that thermometer. Whatever you read on that thermometer (let's assume mercury levels move instantaneously and not be pedantic) then THAT is the current macrostate. I chose this set of macrostates, thus I pick that definition. There is no notion of undefined, the thermometer always HAS a reading.

>Won’t the balls collide with the thermometer even if the entropy doesn’t change? It’s their movement that will take them there.

They can't collide with the thermometer if they're on the other side of the box.

>Consider your state - or any other state, for that matter - at t=0 and the state at t=1ps where the balls have advanced slightly. Is the macrostate different? How? Is the entropy different? How?

Macrostate doesn't change if they're still far away from the thermometer. Still absolute zero. Only the microstate changed. The absolute zero macrostate includes all configurations of particles that will cause the thermometer to read 0. The probability of this macrostate occuring is quite low.

Entropy in this state is low. It increases as more and more particles interact with the thermometer.

The most probable series of events is that particles on the left corner of the box will begin to spread more evenly around the box. More and more particles will begin interacting with the thermometer causing the temperature to rise until it reaches some equilibrium. What can occur is all particles can by sheer luck suddenly concentrate to another corner of the box, but this is a low probability event.

To bring it back around to the main point. All of this is independent of your knowledge of the microstate. Your knowledge does not effect the outcome.
While I agree the double negative is awkward there it would read a lot easier with "small exception" instead of "small exemption" and maybe the author even wanted that word but was writing an article full of the word "exemption" and either made a mistake or forgot.
To be more clear for those less familiar with the operation modes of block ciphers, the CTR mode allows encryption or decryption at arbitrary positions in a text, in a random order, exactly like the ECB mode.

Moreover, the implementation of the CTR mode is trivial when an ECB function is available from a library, a CTR encryption or decryption is done by invoking ECB on some non-repeating value, e.g. the value of a counter incremented after each encrypted block, and computing the sum modulo 2 (a.k.a. XOR) with the plaintext (for encryption) or ciphertext (for decryption).

For random access, an appropriate offset is added to the counter.

When the threat model for a SSD or HDD is only that it might be stolen, the CTR mode is a perfectly secure method to encrypt the SSD or HDD, using the sector number as the counter value.

The slower and more complex encryption modes that have been standardized for full disk encryption, and which are used in most full disk encryption programs, are conceived for the use against a much more powerful opponent, who is not just a thief but who is someone able to access the SSD or HDD frequently, for many weeks or months, without the knowledge of the owner, and who will be able to frequently make snapshots of the SSD/HDD as it evolves during that time, to be analyzed for values that change in time, which can reveal differences between the corresponding plaintexts, which might allow the plaintexts to be guessed (i.e. if a text file is edited frequently, the content of the parts that change between versions might be guessed by the opponent who watches the SSD).

This threat model is valid only for someone who is a person of interest for the surveillance by some TLA.
What's the overhead of using FUSE to implement LiteFS?

Is there an issue with OS compatibility? FUSE tends to require OS hooks, last I checked, and that can be somewhat hairy to deal with.
I'm at least as interested in quality of results as I am in performance; full-text search is not something where there is an obvious single correct algorithm, and is something where results are going to vary between products (and depending on how they are configured, and what configuration options are available).

This is a lot harder to evaluate and compare because it's so not-black-and-white, but... I don't think most people are choosing a full-text search option based on latency alone, are they? While some products may have unsatisfactory latency, most popular products probably do okay, and once you have good enough latency, the issue is results quality.

Getting an overview of pg's fts capabilities, and a list of other products with similar, is I guess a useful starting point. But the article's focus on performance is not too useful to me; are there really an audience of people choosing an fts solution based mostly on performance? I want to know if pg can provide good enough results compared to fulltext-search-focused products -- it's true it's less clear how to measure that, and may depend on your exact situation. Which is why I'd be interested in reading from someone who has something to say on it!
Worth to check it.
