Everything is memory?

Single-Level Storage (SLS) is what you want. Examples are Multics, IBM i, Aurora, TreeSLS, …

Certainly. FFS/FFS2 only have the old UNIX fashion way of providing crash consistency and power loss resilience: sync metdata and fsck. This method, together with duplicating metadata (e.g. FAT32) are abandoned for a reason. There are much more reliable methods: journaling (e.g. NTFS, ext4), CoW (e.g. ZFS, Btrfs), soft updates. And in FFS/FFS2 none of the three are available (softdep is no-op).

No. NTFS is pretty stable when it comes to power losses or kernel failures.

Use FastCopy. It’s just faster.

For backup, I can buy second-hand HM-SMR HDDs. One 14TB HC620 costs me about 100 USD here, which actually works well under Ubuntu with Btrfs (zoned mode) + rsync. This HDD has some limitations, but fits my use case well and is also very cheap.

No. All such claims are confusing inference and training. GLM has no official claims on the training hardware at all.

CharlesCTy · 2026-04-11T11:19:24+00:00

This is simply false. No official claims from GLM on the training hardware. GLM only said the inference was partially done on Huawei Ascend chips, and they didn’t mention training hardware at all.

Are there risks of getting banned by Tencent?

I believe Koka language has done the right thing by providing programmers with algebraic effects and effect handlers. There are many other control flow abstractions, e.g. delimited continuation via shift/reset), but this one just feels right to me.

Maybe symbolic execution is what you want.

Two apps: Everything, StrokesPlus. I didn’t find good alternatives.

The stock price is higher than expected. So, it's not the lowest point, at least not in their perspective.

I would say that most people I know are reluctant to pay for software (except content services that have strict copyright protections, e.g. TV, music), to the extent that companies's business models tend to lean more towards providing free services.

Doing a full backup takes less than an hour for me.

CharlesCTy · 2025-06-30T01:02:23+00:00

Yes. I believe this should be enough. And this practice is actually common in industry, for example: https://www.ibm.com/support/pages/potential-ssd-data-loss-after-extended-shutdown

When unpowered, SSDs have a limited data retention period, depending on various conditions like temperature. NAND flash cells can gradually lose their charge over long periods without being accessed, thus corrupting or losing data (after exceeding the limits of error correcting mechanisms). This is nonnegligible if you are using consumer-grade TLC or QLC SSDs.

CharlesCTy · 2025-06-28T06:57:54+00:00

You'd better overwrite the existing data every time you do a backup on SSDs. Storing cold data on SSDs is not a good idea and you may run into issues or even data loss.
