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.
Medallion has been closed for new investors since ... a long time ago. Nobody has an explanation how they can sustain such an absurd return, but there are a few theories floating around.
Subjectively the one that appeals most to me, is that the fund has an investment strategy built around their ability to identify and capture very specific types of opportunities - and that there are only so many of them globally in any given year. This puts an upper bound to how much the fund even can invest, because their strategy works for scenarios that are limited both in size and frequency.
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.
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.
I'm not a DBA, but as a developer who's worked with Oracle off and on for the last 15 years, I can say that the error messages are frequently misleading, and do, indeed, sometimes appear to be actively malicious. With other databases, they're at worst useless.
Oracle was the first DB I did major work with (12 yrs ago). I have fond memories of that time. I created an automated warehouse management system with it
Pros:
- pl/sql (I like it more than other flavors of sql, maybe because it was the first one I used a lot)
-pl sql developer. Not the java one (sql developer). I loved that you could see tabs in a list and in general it was smooth. I still keep a thin client in my spare drive and use it with delight from time to time
Cons:
-Installing and maintaining Oracle. But it wasn't terrible either
-Having to read Burleston posts. Not sure if this has improved
I know I am biased by my experience, I've heard many horror stories. I wouldn't choose Oracle today, but having to develop for it wouldn't scare me either
> pl/sql (I like it more than other flavors of sql, maybe because it was the first one I used a lot)
pl/sql is not a flavor of SQL, it is a name for the separate SQL-based “procedural” (imperative) language (hence the “pl”) supported by Oracle. The Oracle SQL dialect is usually referred to as “Oracle SQL” if there is a need to distinguish it.
We run a large number of Oracle database for customers. I mostly help manage the application running on top of the database, and we have a DBA team handling the databases.
It's amazing to see how calmly they handle managing Oracle, but their argumentation is also very Oracle-like: It's not a database problem, you're just using it wrong. Which would be a terrible answer, if they weren't right. I think most of us forget that for all the terribleness of Oracle, they actually do build a very stable and performant database, assuming you can afford it.
The funny thing is that a couple of comments up 2 sibling comments basically gave the exact same answer, but one in jest and one seriously. The cryptosphere really is beyond parody
Ha ha. This reminds me of an old project / library [0] I built based on a Quora answer. I wrote libraries for Android and iOS, also wrote a simple server component which could be installed on Heroku with a single click. At the start of the app, it would contact the server for payment status. If server indicated that payment has been made, it would function like normal. If not, it would just crash.
I never used it in any of my projects nor I know anyone using it. I just had an itch of learning Clojure and building libraries for android, and iOS, so I made them.
> Just need to specify the conditions of what "done" or "delivered" looks like
Since it's "just" so simple, can you better explain what those done/delivered conditions might look like? And preferably how that would also be more secure than Escrow.com?
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.
