zerd··on Google have declared Droidscript is malware
Leasing usually isn't cheaper than owning long term though. So your total cost will most likely be higher.
zerd··on Using a GPU Boosts Analytics Performance by 10 to 150 Times
It's pretty well known that GPU crushes CPU in raw analytics DB performance, e.g. all the top ones here are GPU based: https://tech.marksblogg.com/benchmarks.html

Question is how does it perform when the working set doesn't fit in GPU memory?

zerd··on Exploiting vulnerabilities in Cellebrite UFED and Physical Analyzer
I tried to use adb backup to backup my Chrome history/tabs, but it's empty because it has android:allowBackup=false. So unless they're also rooting the phone (which usually wipes the data) or have some 0-day privilege escalations, some apps can't be backed up this way.
zerd··on All my servers have an 8 GB empty file on disk
Reminds me of the speedup loop https://thedailywtf.com/articles/The-Speedup-Loop
zerd··on Reddit’s most popular subreddits go private in protest against ‘censorship’
I think it depends on the age of the post. E.g. this one is showing only two levels for me: https://imgur.com/a/6egEkGB https://www.reddit.com/r/AskReddit/comments/1czuut/what_is_t...

This typically happens if you google something and the answer is on reddit.

zerd··on We Don’t Use Docker
Does the bash script run on Linux, macOS and Windows?
zerd··on 12 requests per second: A realistic look at Python web frameworks
Somehow just.js is faster than Rust and C++ in 20-queries benchmark, they're all using postgres. https://www.techempower.com/benchmarks/#section=data-r20&hw=...
zerd··on Terraria on Stadia cancelled after developer's Google account gets locked
Also if you violate the storage facilities rules and they cancel the lease, they can't turn off the electricity at your house just because they happen to have the same parent company.
zerd··on The Great Suspender has been flagged as malware, removed from Chrome Web Store
One workaround here (haven't tested it): https://github.com/greatsuspender/thegreatsuspender/issues/1...
zerd··on Factorio 1.1 stable
I wish I could fix my bugs at work with machine turrets and lasers.
zerd··on Factorio 1.1 stable
They often don't, which is annoying to no end. You turn around, turn back, and the car/body that you just saw is now gone.
zerd··on Discord bans r/WallStreetBets server, subreddit went private for a while
Even Elon Musk is on WSB discord apparently

zerd··on Show HN: 128-bit, roughly-ordered, URL-safe UUIDs
It's pretty much true for any B-tree based index. You could get around it by using a combined index on another timestamp value, but that's going to be a very large index. Or reduce it by partitioning by e.g. year-month. Even hash-based indices would be slightly impacted due to less locality.
zerd··on The database servers powering Let's Encrypt
My mind exploded when realizing we can read random IO from disk at 40GB/s, which is faster than my laptop can read from RAM. https://spdk.io/news/2019/05/06/nvme/ Btw. using SPDK or io_uring?
zerd··on The database servers powering Let's Encrypt
U.2. The drives have PCIe lanes connected via the blue cables to the motherboard, which is then wired to the CPU. Here's a review that goes into details on the hardware: https://www.servethehome.com/dell-emc-poweredge-r7525-review...
zerd··on The database servers powering Let's Encrypt
> The reason is that the mirrors are expected to fail after the same amount of TBW

You could fix that by writing a bit more to one of the disks, e.g. run badblocks for different amounts of time before putting them in service.

zerd··on I no longer trust The Great Suspender
My wife installed an addon to be able to post Instagram posts from her laptop, and then suddenly clicking on google search results would sometimes, but not always hijack and redirect to bing, and then click on one of the ads. But it was clever because it only happened sometimes, and if she retried it it didn't happen, so whenever she would try to show me, it didn't happen. I just removed all her addons and the problem went way, so not sure which one it was.

> My only wish is they would implement a "family" option where I could easily share my library of recipes with my girlfriend without having to share them one at a time.

I thought that was the paid Cloud Sync feature was for. Does it not work for that?

zerd··on That XOR Trick (2020)
You can also initialize it to an expression, e.g.

    let var = {
      let mut var_ = Vec::new();
      var_.push(1u32);
      var_
    };
zerd··on WRT54G History: The Router That Accidentally Went Open Source
I'm still running a WRT54GL with Tomato firmware on at my parents place. I used it until I upgraded to a faster one, but the reason it's still running is that it provides the longest 2.4GHz range which is perfect for a large house. I've tried Ubiquity, newer ASUS routers and the range is shorter and their devices prefers to connect to the WRT54G. And my parents don't need super fast wifi, just a stable one.
zerd··on Show HN: Keytap2 – acoustic keyboard eavesdropping based on n-gram frequencies
Well known since at least 2004 https://web.eecs.umich.edu/~genkin/teaching/fall2018/EECS598... https://www.nytimes.com/2004/12/12/magazine/acoustic-keyboar...

zerd··on When you browse Instagram and find Tony Abbott's passport number
Also if you have multiple pixelated/blurry images that helps you can reconstruct it more easily, e.g. if different newspapers print pixelated picture of the "suspect" you can reconstruct it pretty accurately.

Machine learning can also do a surprising good job of it, especially if you know what the target is (e.g. a face) https://www.vox.com/future-perfect/2019/9/4/20848008/ai-mach...

zerd··on Unit Testing Is Overrated
> I wrote unit tests >10 years ago for formatting a string for postal codes that I know are still run to this day on every commit because if they get it wrong there is legal recourse for the company that owns that system.

If it's critical for your business I'd categorize that as business logic, not plumbing code, well deserving of unit test coverage.

When I price it out Jarvis is the same price or more expensive for the same size.
zerd··on How to sell open source software: Guacamole case study
Similar with Cyberduck. $24 on the Mac App Store to get one-click install, but you can go to their website and download it manually for free.

You can also use something like requestbin/postbin to capture the whole requests and see IPs, headers etc.

What shelf is that? And what are those foamy things for? Vibration dampening?
zerd··on Unable to deal with Chrome Extension Team, Kozmos is shutting down
Exactly, they have a competing service. They also took down Podcast Addict while keeping their competing podcast app which violated the same terms https://news.ycombinator.com/item?id=23219427
