Today we have an actual stand up comedian trolling HN.
arcza··on Continuously shorting IT stocks overnight and buying back at market open
Correct but respectfully I think you didn't read the post fully. I mentioned within I'd hedge by buying an equal dollar amount of NDX futures which makes it a bit more beta neutral. If those stocks rise, so does the NDX, and my losses on the shorts are offset. But the whole thing won't work anyways due to high trading costs. Unless somehow you can make markets very well at huge scale.

Yeah you're right. Although, how bad would "S3 is deleted worldwide" be? Or "RDS is down for the foreseeable future"? So IDK... The other problem with them is how big they are, so you can't take proportional weights in them, which messes with risk a bit. I think this is a crap strategy but an interesting idea. As others said, the sentiment scanning probably has a better shot, and you pay the huge spread trading outside RTH.

Yep. As a retail guy though, I get no rebate however on that cash. I just pay the 25bps pa AFAICT.

I rushed my post and skipped QA, went straight to production. (fixed, thanks)
arcza··on Ask HN: How to handle user file uploads?
Kinda incredible how nearly every comment here mentions S3. Cloud storage is not the only backend in existence :)
arcza··on Thoughts on low latency trading if exchanges went full cloud
> Instead of a guy on the floor taking dollars from you, you have a bot taking pennies.

^ excellent way to put it

Thank you. I'm only happy to hear this was helpful. I'd also love comments from any HDL quants about how portable FPGA code would be to virtualized environments and what other languages might stand out particularly well for a VM stack.
arcza··on Hello OLMo: A truly open LLM
The nags, the dark patterns, the horrific UI, the soft paywalls, and the tracking, to name a few reasons

arcza··on PM2: Production Process Manager with a Built-In Load Balancer
I like PM2 and it's successfully been keeping my APIs alive quite well, but how does the future look given the popularity of Kubernetes? What is the overlap like and what's not overlapping?
arcza··on Software vendors dump open source, go for the cash grab
What is AWS doing about Redis' new license? I haven't been following.
arcza··on $8,99 per Direct Message – my new project
I have another idea. A proof of work mechanism whereby to send the DM you need to run some expensive WebGL task for ten minutes. Removes the payment barrier and also spam.

Minor point only. Payed is spelt wrong, "paid" is correct grammar
arcza··on Show HN: Linen.team – A lightweight, thread-first Slack alternative
Guess the answer as usual is no.
arcza··on Show HN: Kubetail – Web-based real-time log viewer for Kubernetes
Nice job

Another small suggestion - 14 days seems way too short for a trial; most SaaS trials are 30 and I often end up emailing for extensions before onboarding a new vendor. This is not a cost skimp, it's to avoid making the wrong decision.

Can this be self managed? Major plus if so.

Not everyone goes to the cloud by default. There are many orgs out there that want full data sovereignty for better infosec without relying on someone else's servers.

arcza··on Russian TLD .RU fails DNSSEC validation
Poor blog's getting the hug of death :)
arcza··on Rclone syncs your files to cloud storage
A shame the features don't indicate it can encrypt at rest.
arcza··on Post Office lied and threatened BBC over Fujitsu dev whistleblower
This kind of comment (not your actual comment) shows the pitifully simplistic people making crucial decisions in UK public IT. On prem vs off prem has nothing to do with this yet cloud is phrased as a key tenet of improvement. I suppose give it a few years it'll be described as "LLM ready" too.
arcza··on uBlacklist: Blocks specific sites from appearing in Google search results
Blocking medium.com has been the best thing I've done with an extension in 2023. Thanks uBlacklist!
arcza··on [dead]
I noticed a few sites were loading incorrectly so opened dev tools. Saw https://fonts.gstatic.com/s/opensans/v40/memtYaGs126MiZpBA-U... was not loading. Initially thought DNS but the domain resolves for me to 142.250.178.3.

A Freshworks tool appears to indicate it is down: https://www.freshworks.com/website-monitoring/is-it-down/gst...

arcza··on Beginner dev looks at how YouTube sends videos
Thanks for posting and well done. Small suggestion for your writing style: use less ALL CAPS / BOOM! / WOW! styles and embrace less dramatic wording: it would make your site read more professionally and be easier to digest. Good luck.
arcza··on Live proxy and VPN detection
Another horrible idea akin to anti adblock detection. VPNs are there for a reason and historically originate from corporate LANs needing to extend to executives' company devices. They're now mainstream and many millions of corporate devices will have all egress traffic routed through corp data centres that are by definition VPN endpoints, or cloud solutions like Palo Alto GlobalProtect. Have extreme caution using something like this.

arcza··on Ask HN: E-ink tablet recommendations for self-hosted sync
Appreciate this, thanks.
arcza··on Ask HN: E-ink tablet recommendations for self-hosted sync
I'm almost leaning toward a loose paper notebook, a small desktop scanner for when I get back from the office and coding up a tensorflow OCR automation to run a little container that ships pdfs to Nextcloud in nice folders. If I need to view a previous note, it's on my Nextcloud everywhere. Minimal vendor lock in, actual paper too, but a lot of moving parts.

Agree with others. Need screenshots in the readme.
