There are so many proposals for improving errors, even half implemented ones that are dropped. I even stopped checking pros and cons after a few. As ultimately everything got rejected and the message is that you have to live with verbose checking with llms now.

> and only because by some miracle there are companies out there who started trusting Graphene's attestation keys.

Are the bank apps trusting graphene keys or google them self? Isn't play attestation completely in the hands of google.

Most locations that could provide guaranteed power for western companies with stable governments are also full of NIMBY or NGO who could easily blockade those datacenters. Then you'll have to run to offgrid locations where you have to build 24hr battery for solar with closed loop cooling. Is 24hr battery+solar on earth cheaper than LEO satellites in constant sun without batteries? That's the question that would make or break satellite datacenters, as political climate against AI datacenters is increasingly getting bad with increasing electricity prices.

In case of collision in LEO, wouldn't the debris have chance to go high altitude and cause further collisions?

Regarding Indian private space sector, In addition to skyroot solid rocket, following are noteworthy

Agnikul is planning to launch semi-cryo kerosene rocket pretty soon. Their engine is 3d printed and use electric pump fed 25kN small engine. Planning to launch 4 clustered engines as first stage and already did suborbital test, with some parachute splash down reusability claims.

Astrobase is recent entrant. With decent funding and former ISRO scientists as core team, developing 800kN FFCS methalox engine. FFCS is called holy grail of liquid engines. They have acquired largest metal 3d engine and planning VTVL 1st stage reusability

India has developed ASAT, which is arguably more complicated that ICBM, agni series, they developed. India routinely understates ranges and appear non threatening. Agni5 and 6 are genuine ICBM, and with little tuning could reach anywhere in the world. India's bureaucracy and MEA is beset with gandhian mindset who try to avoid confrontations and minimise belligerence, opposite of PRC wolf warriors I guess.

Not just about PoS device. During early credit/debit card days, lot of stores would pass on merchandise fees directly to customers, giving discount in case of cash transactions, some stores still charge extra. This is not allowed in west as credit cards require same price as cash transactions, and most users perceive credit card rewards as something positive as one would lose out on this rewards when using cash. In India perception is that one would be making loss* if using credit cards. UPI with no fees as of now, is perceived as equal to cash by most people not dealing with black money.

Chaing priority wholesale is not needed just to install kernel image and might break other packages. Just install kernel image from backports after enabling backports.

> apt install linux-image-amd64/stable-backports

Somehow installing with `trixie-backports` isn't picking up latest kernel for me. Used what is being displayed in `apt search linux-image-7`

My personal solution for this is to install a simpler distro in chroot, alpine, and install dev newer apps in to it. Additionally, I run chroot via bwrap sandbox and have been doing this for quite some time now before flatpak became famous.

It's simple power vs energy equations. Let's say you need to supply steady 1MW to town for 1hr, 2hr or 10hr. This needs total of 1MWh 2Mwh or 10Mwh respectively. Let's say battery would cost $200/kwh, then this would cost 200k, 400k or 2M resp. Battery storage is generally used for less than 2hr duration currently where they are price competitive. For the rest, either gas peaker, coal or hydro is used.

Fore more than 2 hours capacity, batteries are expensive than most other and cost keeps increasing as more hours of capacity needed. Without gas or coal to burn when 1hr battery capacity runs out, battery storage is expensive.

> 1 -- Signal jamming exists.

How easy is jamming starlink? I don't think it is as easy as jamming gps. As I've seen numerous warning from Russia that they providing starlink to Ukraine is bad idea. That they're going to shut it down etc. But, starlink is still being used in Ukraine.

After articles on how starship is never getting off launchpad, I'm sceptical of news regarding elon, pro and anti. Sure, things like FSD are hopium or scam, but not everything could be. Haven't seen hard science estimates on their new ai satellites.

It's the slippery slope that's the issue, 24hrs is just the first iteration of the restriction. After couple of iteration of restrictions, they could force everyone to have govt-id approved by goog to install any app.

With the way elections changed after social media became big. Govts want to have control back, like they did before. And are increasingly curbing open internet with boogeyman CP or terrorists, new fear of mass AI CP. Ultimately we'll get 2nd hand version of great firewall and social credit system. Some "liberal democracies" already have root of such systems implemented.

You can write simple http server or rest client with stdlib in Go. No need to include tokio, serde and hundred other cargos which constantly break things. I have apps written in Go more than a decade ago work the same now with recent version of Go. Where as, I had issues with getting few year old github apps in rust compiling and working in rust.
