JacKTrocinskI··on People who die by suicide want to stop suffering, not to stop living
I'm really glad to hear you made it through such a challenging time in your life. Your strength and determination are incredibly inspiring. I'm curious to know more about your healing process. Did you work on identifying and addressing the root causes of your pain, perhaps through therapy or counseling? Sometimes, personal issues can stem from our familial relationships. Did you find that to be the case in your journey? I'm interested to learn more about how you managed to overcome your struggles and achieve the peace you have today.
JacKTrocinskI··on CTEs as lookup tables
CTEs are just a nicer, more readable way of writing a subquery. Also, CTEs can be recursive. In Postgres, CTEs can be useful when used with the RETURNING clause. If you're using the same CTE in multiple different queries, then consider creating a view instead. I wouldn’t use a CTE for lookup values, create a lookup table instead.
JacKTrocinskI··on Ask HN: Strategies for working with engineers that are too smart?
K.I.S.S. - Keep It Simple Stupid
JacKTrocinskI··on Ask HN: Strategies for working with engineers that are too smart?
It sounds like there might be a larger project management issue within your team, though it’s hard to tell from a single example. Features should solve business problems and should come from your clients and/or users and not from engineers. Are your users complaining about your static solution? If not, then why change it? Engineers should work on things that will add value to the business. Arbitrary performance improvements and code rewrites that don’t solve any business issues should be rejected by your project manager.

My suggestion would be to bring this to the attention of your PM. If that fails, then focus on picking up tasks of high value and visibility. Let the “smart” engineers do code rewrites or performance improvements. You’ll have a lot more to show on your resume, feel a greater sense of accomplishment in your work, and will have a greater chance of getting noticed as a star on your team.

JacKTrocinskI··on Project Management: Time Estimations
That's not really a great counter argument, can you explain why you think time estimates are worthless? Do you prefer story points instead? How do you schedule a project with your clients?
JacKTrocinskI··on Ask HN: Should I be panicking about jobs in Europe?
Are you in a low cost or high cost location?

I would expect job cuts in high cost locations to come first.

JacKTrocinskI··on Speeding up sort performance in Postgres 15
They added the MERGE statement!

...and better defaults for the public schema.

Really looking forward to Postgres 15.

The same way Wallstreet does.

Every investment has risks, stocks are not that different from crypto in that regard.

Regulation, once it comes, will help better protect retail investors.

Crypto is still in the early stages, the technology is revolutionary though and I think it's here to stay.

JacKTrocinskI··on Money Stuff is Linear-ish
I think that makes sense and it also shows that an algorithm can in practice reliably find market inefficiencies and solve them in some scenarios. In those cases a free market can exist but the robot will always beat it and eventually discourage all other market participants from participating, essentially creating a sort of communist economic system for that particular market.
JacKTrocinskI··on Money Stuff is Linear-ish
The socialist calculation problem has arguably been solved, check out the Medallion fund by Renaissance Technologies. It has had an average return rate of 74% since 1994. Carl Icahn, Buffet, no one comes close. They have a "robot" that can essentially predict the market, good luck getting them to take your money though.
JacKTrocinskI··on Problems with Oracle SQL
I have worked with the Oracle database for six years and haven't had any major issues with error messages, in fact I'd say Oracle did a really great job building an amazing database.
JacKTrocinskI··on Signs that can reveal a fake photo (2017)
Pretty sure Benford's law applies to images and can be used as a tool to detect fakes.
JacKTrocinskI··on Selling Tiny Internet Projects for Fun and Profit
Would a smart contract help avoid this kind of situation?

JacKTrocinskI··on Coinbase’s listing may break records
Awesome, I hope they expand their crypto listing to include Dogecoin sometime in the near future.
JacKTrocinskI··on Jim Cramer Exposes Illegal Hedge Fund Tactics (2014) [video]
Yes, you have the right link! Sorry, I tried to link to where Cramer speaks @ 7:36 minutes in the clip but HN edited the time element out when I posted, you're link is the the actual thing. I'm not affiliated btw with the clip I shared.
JacKTrocinskI··on Google Deleted over 100k Negative Robinhood Reviews
Didn’t realize we already had a post going, sorry about the dupe!
JacKTrocinskI··on Discord bans r/WallStreetBets server, subreddit went private for a while
That is exactly what censorship is, you don't like how they're acting or what they're saying so you censor them by kicking them out.
JacKTrocinskI··on China wants to build an open source ecosystem to rival GitHub
I wonder if China will ever endeavor to build an OS rival to Windows.
JacKTrocinskI··on Amazon, Apple and Google Cut Off Parler
In that case do you also believe that those responsible for propagating news which sparked riots and looting across the country earlier in the year should also be prosecuted? It seems like both sides have incited violence this year yet from your response it seems like you would only like one side to be punished.
JacKTrocinskI··on Amazon, Apple and Google Cut Off Parler
I will add to that, I believe that in order for a democracy to properly function we need free speech, truly free speech that is. Democracy is not designed to allow the morally righteous side to win power, it is designed to allow the popular majority to win power regardless of what they believe in and the morality of their beliefs. In the U.S. we have a large majority of the public that believes in one thing and another that believe in something radically different and I don’t think we should silence either of them if we want to keep the U.S. truly democratic. The argument that Parlor incites violence is irrelevant in my opinion since violence in this case is the result of free speech which ultimately serves the greater purpose of having a democracy. We should be prepared for the fact that the majority believe in something different than us, even if that something is radically different from what we believe in, and we must accept that and let their voices be heard as well. If we cannot accept what other people are saying than we cannot say the U.S. is truly a democracy since the foundation of that are free speech without limitations.
JacKTrocinskI··on How the U.S. Used Disinformation and the 'Jakarta Method' to Change the World
Russian hostility only really began in 2008, prior to that Russia really tried to have good relations with the U.S. They even wanted to join NATO and offered to help in Iraq. It's the U.S. that soured the relations, not Russia.

EDIT: I am distinguishing Russia from the Soviet Union here.

JacKTrocinskI··on How the U.S. Used Disinformation and the 'Jakarta Method' to Change the World
Unfortunately the U.S. has done a really good job at convincing it’s citizens that there is freedom of the press in their country even though time and time again we’ve seen the mass media in the U.S. severely comprised by corporate interests and/or politics. When is the last time you’ve turned on the news and seen a balanced view given on Russia-U.S. relations? In the last three years the New York Times hasn’t reported a single positive story on Russia or written an unbiased one that would present a counterviewpoint. If we jump back two decades ago the American people were lead to believe that weapons of mass destruction were present in Afghanistan and Iraq and it was the cornerstone of the war initiative there. The U.S. ended up violating not only international law and the sovereignty of the nations of Iraq and Afghanistan but killing thousands, if not hundreds of thousands, of innocent people there on a baseless claim. Today we see the same propaganda being used against countries like Iran, Russia and China. Countries in attempt to defend themselves from U.S. aggression are building nuclear arsenals and the world has become a much more dangerous place to live in as a result. In my opinion this all goes back to freedom of the press, or lack of it.
JacKTrocinskI··on Prestige in US Today
I’m sure Harvard and Yale say the same thing when accepting applicants to their university. I think the thing to consider is how prestige gives an applicant a considerable amount of more sway in an interview process. Also, I worked with a person that moved on to working at Google after working in our project and that individual was considered to be a very poor programmer unfortunately.
JacKTrocinskI··on Prestige in US Today
I think the biggest tragedy of prestige is that many of us use it to automatically assign certain attributes to a person, e.g. if someone is rich then they must be smart or if they have a university degree then they must be intelligent and someone that attends an Ivy league is going to be thought of as more intelligent than someone who attends any other university. I think prestige has began to overshadow too many other important traits people poses like moral values, personal history and accomplishments. It’s a shame it’s the way we seem to gage people now.
JacKTrocinskI··on Ask HN: How's the Kickstarter Union Going?
I live in Poland and in general I would say this is true. I've also noticed that salaries are rising at a very fast rate here for engineers since foreign companies have began setting up shop.
JacKTrocinskI··on Ask HN: How's the Kickstarter Union Going?
I’m a contractor working in Poland right now. I work through a vendor that finds contracts for me at different companies. I recently found out that all the major vendors in Poland have non-compete agreements with each other, meaning they're not allowed to poach each other’s engineers. It actually goes beyond that, I recommended a friend of mine who was looking to switch from his current vendor and got refused an interview with my vendor because of the no compete thing. I think this practice artificially drives down the price of an engineer’s salary and generally is not good for the market. I think HR divisions do something similar as well.
JacKTrocinskI··on Intermittent fasting from dawn to sunset induces anticancer response
I don’t think you should be looking at studies when it comes to how you eat, you should be focusing on how you feel, observing your own body and possibly talking to a doctor. I had a really big problem with acid reflux a while back after I stopped drinking alcohol. I visited many gastrologists and most of them offered little to no help, most only prescribed me drugs which was in my opinion not a solution. I finally meet with a gastrologist that did an endoscopy and basically sat me down and said that if I wanted to get over my acid reflux I needed to eat really light over the next four months, no fruits, no tomatoes, no pork or beef only poultry, no fried food, no greasy food, and the list went on. I did the diet, had a few cheat days because it was hard, and my stomach recovered. After the four months I reintroduced certain foods and started learning about how my body reacted to them. I also realized that I feel a lot better with a full stomach than with an empty one. My point is we all have slight different bodies and that while studies are great, sometimes it just good to study yourself and how you feel. On a side note, if you’re one of those people fasting to be healthy yet haven’t cut out drugs, alcohol and tabaco out of your life then do that first, it is the first step to good health.
