Interesting! Would you mind elaborating?

Exactly! It seems to understand enough about what the commands mean and is able to carry the context forward even if it isn't exactly executing them.

Sure someone must have posted online about ls and rm, but a jumbled combination of those where the model is able to keep track of files listed, created and deleted in the specific context of the chat? Mindblowing!

I don't recall correctly but there was this patent/paper discussing how Facebook (& perhaps a few others) use the EXIF data to confirm and expand your social graph. I guess processing the pictures already gives them everything they need to identify different people who were at the same place at around the same time. But all that meta data like timestamps, geolocation, camera make and model etc. must definitely provide them a great deal more info to be sure about that.

And if one company can do it, I don't see how others can't or won't do it in the future. And only God knows in what all other ways this information can be exploited.

I recommend everyone to clean up EXIF data before they send out files to friends and family or upload backups to the cloud.

I found the CLI tool at https://exiftool.org/ to be very useful. It helps remove EXIF data from a wide variety of file types and comes with tons of filters and features to observe and selectively manipulate & remove EXIF data.

This is what's so surprisingly scary about time value of money to me. Many "spectacular" investments that double or triple money over a decade or 2 are simply not all that great if you just calculate the annualized return and factor in the inflation.

Back home, I've had so many agents try to sell me inferior insurance and investment opportunities dressed up as insane deals hoping I wouldn't look too much into the details. I was really lucky to come across the folks at /r/indiainvestments who frequently warn about this. But I am sure there are many others who are not aware of these things and fall for them.

Sent in a SQL command deleting multiple million records (intended) wrapped in a single transaction (not intended). The replication queues could not keep up and failed, bringing down most of the replicas. Master server kept trying to recover and maxed out all connections - no DBA could log in to perform manual recovery. We had to hard reboot not knowing what state the system is in and how long it'll take to fully recover. Did I mention that this was a few hours before trading was going to begin?

TBH, my team was very gracious about it and the RCA focused purely on the events that occurred and how to never let if happen it again. No blame game at all.

I believe it is when you review your colleagues, they review you and your manager collates all the reviews to access your performance. Some places allow you to nominate who you want to provide your review, perhaps people you worked closely with the last couple of months etc.

Yep. It was supposed to be a very small change. I blundered. My team understood that and was super supportive about it all too. But this was after it was all fixed.

During the outage though, no one (obviously) had time for me. This was a very important server. The tension and anxiety on the remediation call was through the roof. Every passing hour someone even more important in the chain of command was joining the call. At that time I thought I was done for...

Welp, as a new grad there, I had brought down one very important database server on a Sunday night (a series of really unfortunate events). Multiple senior DBAs had to be involved to resuscitate it. It started functioning normally just a few hours before market open in HK. If it was any later, it would have been some serious monetary loss. Needless to say, I was sweating bullets. Couldn't eat anything the entire day lol. Took me like 2 days to calm down. And this was after I was fully shielded cuz I was a junior. God knows what would've happened if someone more experienced had done that.

For a second I legit thought Google banned my account for some reason. And I don't like it that I feel relieved..

I am sorry, but that hasn't been my experience at all. Both on Windows and Android. I've noticed that Firefox eats up far more memory than chrome with way lesser open tabs on both the platforms. I've had tabs die on me multiple times that I simply could not recover. At this point I am very conscious when I am using Firefox because I don't want too many open tabs or leave them open for too long.

I'd love to use Firefox and ditch Chrome completely, but I don't think its there yet.

And I was surprised to know that this has made its way into hiring! So, the job hunt is going to get even more superfluous? Really reminds me of that Episode in Black Mirror, where everything depends on your rating..

Or maybe they should secretly ship the shirts with a large "spam PR" written on it for those who raised spammy PRs.

A lot of those accounts also seem to be created just a few hours before October 1st. Can GitHub time gate new accounts before that can make public PRs?

I am an Indian, and I've studied at an Indian university for my undergraduate degree, and I've witnessed spam like this everywhere. Not hacktoberfest, but I've been a part of it myself for some of the other things. Wish I had behaved better.

In most of these cases, it usually starts with someone really talented doing it with all the good intentions, and everyone else wanting to get in on that 'swag' and appear just as 'talented' and 'unique' amongst their peers. The freebies are mostly for 'show off'.

A few hours ago this link showed extremely low effort LeetCode/Programming Challenge problems and solutions aggregation repos created by us Indians (disproportionally more than any other country at the time I checked) with very silly open issues created & marked as 'hacktoberfest2020' (looks like some of them are gone now)[1].

But, from what I heard from my uni recently, things are improving and this year folks are trying their best to form groups to focus on meaningful contribution over spam.

Even after all that, unfortunately for us though, we'll still have bad actors, probably at the same percentage as any other country, but amplified due to our population and hyper-fixation with an unreal perception about most things we do.

This. I've given up trying to figure out new ways to get around all the censorship. Not to mention, the current govt. has proven that it's ready to use any excuse to take punitive action against any citizen it disagrees with. Seen enough of journalists getting jailed and raided, people sharing comics criticizing the govt. getting charged with sedition and in some cases getting beaten up by the local 'gundas'..

This is something that bothers me a bit. On my PC memory usage spikes even after having tabs open for a short while.

I've recently shifted to Firefox and I noticed that after opening 10-15 tabs on about 3 separate firefox windows the memory usage is way higher than Chrome's. I have seen lesser memory usage on Chrome for way more tabs and windows.

I have very similar observations on my android phone as well. I've had 100+ chrome tabs open on my phone with no hiccups, but about 20-30 in, on Firefox, my entire phone slows down to a crawl and tabs start crashing etc.

Is it just me?

If you have an account you can set this as the default. old.reddit.com + RES works really well for me. I really hope old.reddit.com does not go away.

I had worked on an application that saw less than 100 writes per minute and about 1k reads per min and used a caching layer in front of the DB. Not only was the cache actually slowing us down, it was also inconsistent with the DB. Can't even begin to express the amount of lost dev time and productivity. We couldn't get rid of it, because someone above was convinced that we would need it to scale in the future.

Amazing book. Truly astounding sequence of events.

Greatest irony of all, they named their firm "Long-term Capital Management", while taking hugely leveraged short-term positions ($1 trillion dollars worth of derivatives backed by about $100 billion or so assets) that were beyond the understanding of anyone else. Didn't last 4 years before they blew. They did show 40% annual returns when they started and I guess that's what kept them going without much regulation. But man, did they crash hard. Investors who were returned their money after a year or 2, and those who were turned down from even investing must have thanked their Gods for saving them from absolute destruction.

There is another book by Michael Lewis (who also wrote "The Big Short") called "The Liar's Poker", where he talks about his time at Salomon Brothers and how they collapsed in a very similar fashion. Highly levered derivatives with a magic formula that has worked well (so far..). It's fascinating how they were allowed to do what they did. Open gambling with client's money, and no repercussions on loosing it all. "Blowing up a customer" was apparently common and chalked up to a rookie's mistake. "Baptism by fire". How did the rookies even get access to millions of dollars of money to bet on crazy derivatives!!

I feel that every time a major upset in the financial markets lands on us, it is because some group of really talented people managed to convince everyone that they discovered something that no one else has and have "cracked the market" by showing consistently high returns for a period of time, and gain access to huge pools of capital. Only, after a few years the market turns around, showing a side of things that they did not take into account and the whole thing goes belly up, market crashes, loads of people loose money, mostly its everyone else but that group (leverage, borrowing, access to someone else's capital etc).

And because everyone who was supposed to keep them in check did not do it because despite it being their job not to, they did take them for their word, they try to cover it all up by paying the very people who caused all the trouble and who were supposed to watch out for all this.

Banking world seems to have a lot of conflict of interest all around. It is much better now, with lots more rules and regulations, but it is still there.
