Reminds me of the time when I bind mounted my home dir in a chroot, then rm -rfed the chroot when I no longer needed it...

I think most open-source contributions come from a tiny fraction of users who initially get involved because they want to improve the project or fix a bug for their own usage

I did not have the money to pay the insane amounts these greedy for-profit certificate authorities asked, so I only remember the pain of trying to setup my self-signed root certificate on my several devices/browsers, and then being unable to recover my private key because I went over the top with securing it.

In my experience, OnlyOffice has the best compatibility with M$ Office. You should try it if you haven't

On this day, exactly 12 years ago (9:30 EDT 1 Aug 2012), was the most expensive software bug ever, in both terms of dollars per second and total lost. The company managed to pare losses through the heroics of Goldman Sachs, and “only” lost $457 million (which led to its dissolution).

Devs were tasked with porting their HFT bot to an upcoming NYSE API service that was announced to go live less than a 33 days in the future. So they started a death march sprint of 80 hour weeks. The HFT bot was written in C++. Because they didn't want to have to recompile once, the lead architect decided to keep the same exact class and method signature for their PowerPeg::trade() method, which was their automated testing bot that they had been using since 2003. This also meant that they did not have to update the WSDL for the clients that used the bot, either.

They ripped out the old dead code and put in the new code. Code that actually called real logic, instead of the test code, which was designed, by default, to buy the highest offer given to it.

They tested it, they wrote unit tests, everything looked good. So they decided to deploy it at 8 AM EST, 90 minutes before market open. QA testers tested it in prod, gave the all clear. Everyone was really happy. They'd done it. They'd made the tight deadline and deployed with just 90 minutes to spare...

They immediately went to a sprint standup and then sprint retro meeting. Per their office policy, they left their phones (on mute) at their desks.

During the retro, the markets opened at 9:30 EDT, and the new bot went WILD (!!) It just started buying the highest offer offered for all of the stocks in its buy list. The markets didn’t react very abnormally, becuase it just looked like they were bullish. But they were buying about $5 million shares per second… Within 2 minutes, the warning alarms were going on in their internal banking sector… a huge percentage of their $2.5 billion in operating cash was being depleted, and fast!

So many people tried to contact the devs, but they were in a remote office in Hoboken due to the high price of realestate in Manhattan. And their phones were off and no one was at their computer.

The CEO was seen getting people to run through the halls of the building, yelling, and finally the devs noticed. 11 minutes ahd gone by and the bots had bought over $3 billion of stock. The total cash reserves were depleted. The compnay was in SERIOUS trouble...

None of the devs could find the source of the bug. The CEO, desperate, asked for solutions. "KILL THE SERVERS!!" one of the devs shouted!!

They got techs @ the datacenter next to the NYSE building to find all 8 servers that ran the bots and DESTROYED them with fireaxes. Just ripping the wires out… And finally, after 37 minutes, the bots stopped trading. Total paper loss: $10.8 billion.

The SEC + NYSE refused to rewind the trades for all but 6 stocks, the on paper losses were still at $8 billion. No way they coudl pay. Goldman Sachs stepped in and offered to buy all the stocks @ a for-profit price of $457 million, which they agreed to. All in all, the company lost close to $500 million and all of its corporate clients left, and it went out of business a few weeks later.

Now what was the cause of the bug? Fat fingering human error during release.

The sysop had declined to implement CI/CD, which was still in its infancy, probably because that was his full-time job and he was making like $300,000 in 2012 dollars ($500k today). There were 8 servers that housed the bot and a few clients on the same servers.

The sysop had correctly typed out and pasted the correct rsync commands to get the new C++ binary onto the servers, except for server 5 of 8. In the 5th instance, he had an extra 5 in the server name. The rsync failed, but because he pasted all of the commands at once, he didn't notice...

Because the code used the exact same method signature for the trade() method, server 5 was happy to buy up the most expensive offer it was given, because it was running the Sad Path test trading software. If they had changed the method signature, it wouldn't have run and the bug wouldn't have happened.

At 9:43 EDT, the devs decided collectively to do a "rollback" to the previous release. This was the worst possible mistake, because they added in the Power Peg dead code to the other 7 servers, causing the problems to grow exponentially. Although, it took about 3 minutes for anyone in Finance to actually inform them. At that point, more than $50 million dollars per second was being lost due to the bug.

It wasn't until 9:58 EDT that the servers had all been destroyed that the trading stopped.

Here is a description of the aftermath:

It was not until 9:58 a.m. that Knight engineers identified the root cause and shut down SMARS on all the servers; however, the damage had been done. Knight had executed over 4 million trades in 154 stocks totaling more than 397 million shares; it assumed a net long position in 80 stocks of approximately $3.5 billion as well as a net short position in 74 stocks of approximately $3.15 billion.

28 minutes. $8.65 billion inappropriately purchased. ~1680 seconds. $5.18 million/second.

But after the rollback at 9:43, about $4.4 billion was lost. ~900 seconds. ~$49 million/second.

That was the story of how a bad software decision and fat-fingered manual production release destroyed the most profitable stock trading firm of the time, and was the most expensive software bug in human history.

Blocking the DNS was the first thing I did. This is intended to restore the map feature without having to trust a random company I've never heard of.

What do you mean by "a diff of a code fix" that would be simpler ?

Quoting one dev from the conversation I had on Discord :

the one run by OSM is not intended for general purpose use because that results in way too much load on their system. We used to use theirs, but as Immich grew we decided that we should relieve them of that

I guess you (and they) are talking about raster tiles, since OSM does not seem to provide vector tiles

When I mentionned that "I can confirm it is not realistic to self-host a tile provider", it's because I tried to run maptiler : it maxed out my CPU for 2 hours before my disk got filled while trying to generate the tiles from OSM data (and it was just for France)

Edit : Anyway, I don't think this should be in Immich's scope. Simply providing an easy option to switch tile providers would allow people motivated enough to host maptiler to use it

Edit bis : More details on how hard it is to host your own tile provider are available on the official OSM wiki

Downvoted for cropping out the reference to the original...

The worst thing about eclipse I've had to deal with is its git integration. The conflict resolution tool is awful and half the terminology diverges from plain git.

The fact that it has a "Push & Commit" button also drives me mad far more than it should

What's up with all the shilling posts lately?

This has existed since at least 2018 according to their Twitter, and is related to crypto currencies through its Radworks DAO

Edit : I'm not saying OP themselves is a shill. Radicle did a pretty goog job at hiding its cryptocurrency ties. They even renamed their token from Radicle to Radworks a few years ago. It seems like cryptobros are adapting to the fact that being related to cryptocurrencies hinders adoption among technical people.

For anyone who wonders, this is related to cryptocurrencies
