Apple stock is up 18% in 2026

It assembles and pivots to own root filesystem. The filesystem mounts dirs and files from your original filesystem, most of them in read-only mode, but does not mount files that ex…

I work on a sandbox which has similar isolation level to Podman (rootless Linux user namespaces), but with UX optimized for local development work. Take a look: https://github.com/…

Normal vending machine transactions are B2C transactions, so the buyer cannot be a company - cannot pay with company money and cannot deduce the payment as the company cost. I gues…

With payments the complexity is not only in accepting a payment, but largely in doing so legally. Someone makes a request to my company's paid service, I return 402 and get a stabl…

You are right, but if stock repurchase does not increase market cap, dividend payment still decreases it (unless it would be fully reinvested in the same stock, which it is not, it…

Could outperformance of largest cap companies be partially explained by dividends paid by smaller caps? Reasoning behind this: * Index investing raises in popularity, with index fu…

I work on a Linux sandbox that makes it easy to hide sensitive files from AI agents while keeping the files they need accessible. Check it out: https://github.com/wrr/drop

I made a sandbox to productively work with agents while restricting files they can read and write: https://github.com/wrr/drop

one possibility is that some heavily indebted AI infrastructure company will be unable to meet its dept obligations, which will cause banks that become heavily exposed to AI-infras…

sp500 has profitability requirement, I doubt LLM companies will show profits any time soon.

When I was doing Fast.AI Deep Learning course, I was surprised by the number of Python dependencies machine learning projects bring. Web front-end projects were always considered v…

An interesting variant of a web phishing attack is to combine the back button hijacking with information that comes from the HTTP referer header. HTTP referer discloses from which …

I'm working on a sandbox for Linux terminal work with UX similar to Python virtualenv: https://github.com/wrr/drop

Recently I was wondering how viable it is to launch a niche, paid tool for Linux. I found that this is a very rare model, most tools are either just free, supported by sponsorship,…

OK, I see, so a limitation is also that I cannot block an individual script, I need to block a Python interpreter.

I'm not a Little Snitch or Open Snitch user, I wonder if these firewalls are able to block requests done with the use of some other, allow-listed program. Say I run a script `suspi…

Check also https://github.com/wrr/drop which is a higher-level tool than bwrap. It allows you to make such isolated sandboxes with minimal configuration.

Drop is a Linux sandboxing tool with a focus on a productive local workflow. It isolates programs and agents while preserving as many aspects of your work environment as possible. …

Is the OS implemented from scratch, or is it a stripped down version of some existing OS?

In Europe there have always been a good selection of affordable, entry-level vehicles, but recently these affordable choices have largely vanished. Toyota Corolla, the best-selling…
