rythie··on SQLite briefing for Linux kernel hackers (2019)
I tried the same test on a different system with spinning drives, it took 1 minute 43 seconds. The resulting file is 12kb (all inserts, no deletes or updates). It’s sync writes that are slow.

Sqlite is in loads of things, Firefox, VSCode etc., if you have NFS home directories you can have issues. KDE’s akonadi uses MySQL via localhost, though it can’t handle you being logged in more than one place. My view is that a JSON or XML file would work a lot better.

It’s very slow at writing over NFS. I wrote a simple python script writing 1000 entries, committing after each one, in WAL mode. In Fedora 22 VMs, NFS4.2 default settings, no security, SSD on host machine.

  - local speed = 2 seconds
  - NFS to another VM = 31 seconds
  - NFS via localhost = 17 seconds
rythie··on Lightroom app update wipes users' photos and presets, Adobe says not recoverable
Photo mechanic is great, you can import from a card and put the files on any mounted drive. You can set the import from a card to rename the files by date or other Exif info and into directories in the same way. It can browse directories without importing.

I don't think it can find duplicates, I typically I use a file duplicates tool for that type of thing.

Adobe's Bridge product also does some of this, but I haven't used that in a few years.

rythie··on Does simultaneous multithreading still make sense?
I didn’t spot that one, though it was almost 10 years ago and I don’t see more recent examples. My point was that a large number of users don’t actually have hyper-threading on the desktop.
rythie··on Does simultaneous multithreading still make sense?
Intel i5 desktop chips don’t have hyper-threading (SMT) and haven’t for the 10 years they’ve been available. Typically the i7 variant of the same CPU has been about £100 more (roughly 50%). The point about only 5% extra die space makes no difference to the consumer, as there is/was quite a high cost premium on desktops for that feature. Now Intel has removed hyper-threading from most of it’s i7 desktop chips, and you get 2 extra cores over the i5 version instead.
rythie··on AMD’s Entire Ryzen 9 3950X 16 Core CPU Inventory Sold Out in Japan
Blackberry's stock price went up 10x in the year after the first iPhone was released.
rythie··on HPE Drive fail at 32,768 hours without firmware update
New drives already had the updated firmware back in May when I bought some.
rythie··on They Might Never Tell You It’s Broken
I tend to assume anyone who reports a bug is likely about the 10th person to experience the issue if it’s a big issue. Probably 100th or more if it’s a more minor bug. You can sometimes see this for yourself if you have logs that report 404/500 or other error and compare it to the bug reports you get - of course often with open source you don’t have that info.

As a user it’s more effort than it’s worth to report bugs and when you do people argue that it’s not a bug or take a year to fix it, which is then only in some dev version you won’t see for years. This includes stuff I pay for like Spotify.

rythie··on Thomas Cook collapses, stranding 150k UK holidaymakers
Not just bad reputation, it's against the law in many countries. It's given as example of the False imprisonment wikipedia page [1]:

"The detention of a customer by a business owner (e.g., hotel operator, apartment owner, credit card company) for the failure to pay a bill."

rythie··on iPhone 11 Pro and iPhone 11 Pro Max
Apple stuff lasts, this is not an Apple issue, any of those phones would have been good for several years. I'm only my 3rd iPhone in 9 years (soon to replace it though). Also 3rd iPad in 9 years. My Macbook Air is from 2012. Apple do software updates going quite far back. A lot of Apple's hardware looks exactly the same from generation to generation, so even if you updated, how would anyone know? If customers want to chop and change that's on them, Apple is not forcing it really.
rythie··on iPhone 11 Pro and iPhone 11 Pro Max
The ultrawide lens and night mode are significant in my view, if you don't already have them.
rythie··on Apple lightning to HDMI adapter is a computer
The main reason is probably that 1080p30 is 1580 MBits and USB2 is only 480 MBits, so it has to do decompression.
rythie··on Amazon Accidentally Sold $13k Camera Gear for $100 on Prime Day
That’s a ridiculous solution. Many of those products can’t go online by themselves, that $13,000 lens can’t and most the cameras talk to a phone only, not the internet, and that’s even if people use that feature. I don’t why Sony, Canon or others would even consider this when no other retailer has this issue.
rythie··on Amazon Accidentally Sold $13k Camera Gear for $100 on Prime Day
I’m not sure the bad publicity is worth it. People will who read the press about it, will doubt the real deals are real and not order them (e.g. 50% off, which is big saving, but still happens). Amazon is big company with a lot of good engineers, seems like they should be able to solve this problem.
rythie··on New 2019 MacBook Air features a slower SSD than 2018 model
It's still very fast. Less than 2 minutes to read the entire drive of the base model. It's more than twice as fast as any SATA SSD. Similar to 2017 Macbook Air for read speed and much better write [1]

I'm sure for almost all users of those machines, the SSD is more than fast enough for everything they want and big upgrade from HDD based Windows laptops many will be switching from (those were typical 3-4 years ago and even now are still around).

rythie··on Fast key-value stores: An idea whose time has come and gone
Memcache was released in 2003, we didn't start to see server SSDs until 2008. For many places, if you put the database on SSDs, it's fast enough.
rythie··on Changes to Models S and X allow them to travel longer without larger batteries
I've mostly had older cars 5-10 years old and I rarely had issues with anything in the engine. It was typically suspension, brakes, lights, the starter battery etc.

Tesla make it's difficult to fix their cars by restricting parts or bricking their cars that have been in a crash. Whilst you can get your traditional car fixed pretty much anywhere, likely to get your Tesla fixed you need the dealership more than ever.

rythie··on Qualcomm and Apple agree to drop all litigation
They've got 6 years to work it out.
rythie··on FB plans to pass your photos to advertisers, make users the stars of online ads
That’s not the same thing. Advertising a product involves using someone’s likeness to endorse a product, which is strictly controlled in many countries. It’s not the same as having adverts in the feed next to your content. I’m sure facebook would have to get individual consent, e.g. do you want to endorse CocaCola?
rythie··on FB plans to pass your photos to advertisers, make users the stars of online ads
I can’t see how this would be legal. As a amateur photographer myself, I know that to do a commercial photo like this, to advertise a product, I’d need model releases and a potentially a property release. Neither of these are needed for editorial images or people’s own personal pictures. I can’t see the facebook could do this via the EULA, so they’d have to contact everyone identifiable in the pictures - which I suspect would mean it’s not viable for them.
rythie··on Stop Brexit: 700k sign UK petition to stay in EU
This site tracks both of them: https://brexit-petitions-count.now.sh/
rythie··on Dropbox adds a device limit to free accounts
I think it's something to do with extended attributes - though why they need them now, after all these years, I don't know.
rythie··on Linus Torvalds on Why ARM Won't Win the Server Space
Your second point is just re-enforcing what he said. If MacBooks move ARM, they will have solved developer piece. Since so many developers use Apple stuff, ARM will be native and servers would follow.

In the 90s you could see a shift from people having a SPARC workstation in their office for service development, to just using a x86 PC with Linux or Windows on. Then after while developing for Linux/x86 and deploying to Solaris/SPARC made little sense, so you just put it on Linux/x86 in the end. The thing is maybe 95% of things just work and you spend all your time sorting the other 5%.

rythie··on Apple resumes selling iPhone SE at lower $249 price on its clearance store
I'm sure it is for most people. I've always taken pictures of my niece and nephew on a decent camera, I'm pretty sure they'll last the test of time. Every new phone claims to have a good camera, when to me it's still not good enough and doesn't justify the £700+ for a new phone.
rythie··on Apple resumes selling iPhone SE at lower $249 price on its clearance store
I totally agree with this and on top, for me personally, I don’t care about the obsession with better cameras in these phones (now multiple modules adding to the cost). I always carry at least a compact camera (RX100m3), and often a full frame mirrorless camera.
rythie··on NH judge orders Amazon to give Echo recordings in murder case
Apple lets me select which apps can access to both the microphone and the GPS. Of course you have to trust Apple, though they've made a big thing about privacy, as the biggest public company in the world, I don't think they'd risk lying about that.
rythie··on Flickr free accounts will soon be limited to 1,000 photos or videos
My dad died a few years ago, he was a keen flickr user and member of many groups, so we kept his account alive. Fortunately, it looks like he just over the 1000 limit, so we just have to prune 100 or so photos.
rythie··on Removing Old Versions of TLS
Why wouldn't they just put a TLS1.2 reverse proxy infront of whatever legacy system is there? or use cloudflare? that'd be way easier than telling people to reconfigure their browsers to be insecure everywhere on the web.
rythie··on How I’ve Attracted the First 500 Paid Users for My SaaS
If you have 500 customers and your competitor has 500 customers. You are in a market of over 10,000 potential users.

What do you do? go after your competitor's 500 customers, many of which are only going to consider switching if their product lets them down or go after the other 10,000 potential customers that don't use either product?
