Hypothesis – Haskell QuickCheck Like Testing for Python

I jumped on this at first as well. But to be honest if their target demographic is industrial production of coffee like beverages (like those Star Bucks soda can ”coffees”), well then it might not be so bad. I was thinking that a lot of flavour compounds of espresso breaks down quite rapidly while the drink cools, so the method of cooling all drinks to equal temperatures could be enough to skew the results regardless, but again for commercial coffee based soft drinks this is already the case. Headline is a bit misleading though.

According to the article they see the main use for industrial scale production of coffee/espresso based drinks, in that regard it does make sense. For home use not so much even if there could be some niche market for cold espresso drinks at home, using less ice would allow for less dilution and faster than prepping and then refrigerate the coffee. I sometimes put concentrated ice coffee into my whey/oat shakes, but this is indeed very niche use even for me.

New iMac with M4 2 years ago

You probably know this but it’s possible to buy a controller card for the panel on Ali Express and retro-fit into the case and use as a monitor if you are ready to retire the computer itself.

I’m contemplating doing this myself at some point but my maxed out 2019 iMac upgraded to 128GB ram and extra SSD is still plenty fast for me, actually feels subjectively quicker than my M2 Pro MacBook Pro with significantly less ram feel. I was a bit surprised as I had read all the hype of the responsiveness of the Apple M-machines.

Then I will put this one on my to read list. I actually re-read the book by Vinge recently after he passed.

I can only talk from personal experience I did not trust most online payments around the turn of the millennium, but I did order quite a few things online. I usually payed either by collect on delivery or by invoice like regular good old fashioned mail-order, or by the early 00s VISA had something called e-card or similar, where you could generate a temporary one time use CC via a Java applet, this card was only valid for a day and could only be charged by a pre-determined amount, making the risk very low.

From what I can see this doesn't contain any kind of permission model, or authentication. At least what I could see in the documentation. I would say that RLS is one of the big killer features for postgrest which makes it so great for rapid prototyping something that's actually useful when exposed to the open internet.

Isn’t this the reverse? Providing USB-C rather from a power source rather than powering from a USB-C supply.

I have a side project where this would fit perfectly. I’ve for a database in Postgres and my plan have been to sync the data into a local SQLite for a react-native app which needs to work offline and with flaky connections, to then later sync it back into PG. I have never gotten around to actually build the sync and it looks like this could solve that problem.

Does this play nice with RLS? I’m running everything on Postgrest at the moment.

Microsoft have a similar problem relaterade to them merging a lot of services but not accounts. I have an old Xbox Live account on my Xbox 360 which I can’t reset the password for since the email/username was the same as for my Skype account and my Hotmail/MSN account back in the days. This mess is still causing me tons of problems anytime I try to log in to something Microsoft related.

Just curious but wouldn’t a Mac Studio paired TB4 PCI-E expansion board/dock fill this same purpose? Is there something inherently in the Apple ARM arch preventing this? I’m still on a Intel iMac where such a solution works a charm, so my natural upgrade path would be a Mac Studio and display. Of course you are still limited to your thunderbolt bus but I guess TB4 is good enough for a lot of PCI-E use cases.

Or you know a can of bottled air upside down and a bootable usb will do it unless the efi is locked down and USB-boot disabled, in that case you also need to move it over to your own laptop.

I’ve seen my fair share of web-apps where the subscription check is entirely client side JS and a simple self MITM is enough to bypass payments. Not saying this is the case in this particular instance but it’s definitely something I’ve seen more then once.

I’ve brought it up as an issue with some companies but I’m usually met with a shrug and a response in the realms of “our users wouldn’t know how to do that”. I’ve even seen car charging poles with entirely client side JS to validate account/login to charge for the electricity.

I too have grown up, playing games with a hex editor in one hand and tcpdump in another so I have a habit of poking around to see how stuffs made.

OpenSSH versus SSH 3 years ago

Yeah I was thinking of something like that. But I still feel a bit uneasy with configuring OpenSSH securely, I’ve escaped such setups before, gaining full shell access through exploits. Maybe I’m overly paranoid.

OpenSSH versus SSH 3 years ago

This makes me think about something I thought of a while back, is there any library/app which lets me expose a TUI/cli-app over ssh without actually caring about securing OpenSSH for this use case?

Yes this is what I do, and I wouldn't have dedupe for all datasets, for instance in this case he wanted dedupe on his games, so I would just enable it for that dataset.

But I do run disk-wide compression with no problems and have done so on all my datasets for many years now, and it's been a tremendous space saver. Especially on machines where I have a lot of VMs/containers, it's not unusual for me to have a compression ratio of 2 on these with good old lz4, it will be interesting to see what damage zstd will do once I start experimenting with that.
