bedros··on SQLite small blob storage: 35% Faster Than the Filesystem
sqlite works in memory most of the time, on disk sometime when flushing, faster

filesystem, works on disk most of time, in memory some time (some buffering), slower

which makes my original comment true,

bedros··on SQLite small blob storage: 35% Faster Than the Filesystem
I'm no expert in FS or sqlite, but as everyone knows, filesystems are not good processing small files, having an application that bundles in memory small blobs and then flush them to disk as a single file, is what make it faster.

ReiserFS 4 was (I believe still is) the only FS that improves small files performance by bundling small files and stored them on disk as a single blob.

as for that person who downvoted my original comment, I'd love to hear from you why you think I'm wrong. you don't just downvote comments because you disagree.

bedros··on SQLite small blob storage: 35% Faster Than the Filesystem
it's basically storing in memory vs storing on a disk

it's not sqlite vs filesystem it's memory storage vs disk storage

bedros··on RISC-V Foundation
I don't know how much work is done on this, but you guys need to build an eco system such as theon once I get ARM CPU, I know there lots of IP which I can used in SOC with easy plugin integration

Also, easy debugging like ARM coresight, is critical for adopting this ISA

wish you all success, we need open ISA

bedros··on PCIe 4.0 will be twice as fast as today's slots
this is actually correct, electric signals are actually about 6inches or 15cm per nano second (not seconds)

bedros··on PCIe 4.0 will be twice as fast as today's slots
I'm no expert on pcie signaling, but I have some general idea,

problems are how to take care of the electromagnetic noise, that's why PCIe uses differential pairs wiring (both positive and negative wires are next to each other on board) instead of single-ended (single wire with common ground, negative) which were used in original PCI and PCI-X so the if some noise hits the first wire, same noise hits the second differential wire.

improvements in coding and decoding the signals with error correction also help recovering any errors caused by the electromagnetic noise.

no way electrons speed is at centimeters or even millimeters per second, electrons travel at or close to speed of light.
bedros··on Vultr: Digital Ocean alternative
typical bait-and-switch they advertise $2.5 plan, but they've been sold out for ever.

I was considering vultr, but not after scamming me with bait-and-switch

bedros··on Jamboard, by Google
I agree, google is the new microsoft, they try everything they can to lock customers in.
bedros··on Accidentally destroyed production database on first day of a job
I'm guessing this feature was never tested properly

we all assume code (or feature) that are not tested should be assumed to be broken

where's D-lang? it would be interesting to compare D with C, C++, and Rust

can you guys support digitalocean?
bedros··on How Anker is beating Apple and Samsung at their own accessory game
I've purchased 4-5 anker battery packs and usb chargers, very happy with quality of product, however recently switched to ravpower because of lower price for, as of now, comparable quality, so far I purchased battery pack and USB charger (6 outputs) for 30% cheaper than anker.

I have no connection to either company, this is my personal experience, and both make great products.

bedros··on Android now supports Kotlin
why not use llvm as virtual machine instead of JVM assuming backward compatibility is not an issue.
bedros··on Ask HN: Secure automated backup?
I second borg backup, I use it on my linux/mac machines

for windows I use reflect backup https://www.macrium.com/products/home

I tried acronis backup, but the disk restore failed, absolutely horrible software. then tried reflect disk restore was very smooth.

bedros··on Startup CTO – Premature Scaling
Simply, to counter the flood of new users, build a Dam called waiting list, the slowly activate users as you build capacity

Put priority on paid users vs free, to cover server costs

bedros··on Key differences between Python 2.7.x and Python 3.x (2014)
I'm using Django 1.8 first with Python 2.7 then migrated the code to 3.4 with no problems
bedros··on Show HN: R8 Processor
be careful with trademark from ARM, they already have R5 and R7 cpus, I'm not sure about R8
bedros··on Ask HN: need feedback on using Vultr VPS hosting for production?
Thanks for the feedback; vultr seems to have newer hardware which results in faster servers; but I also read some where else about their bad customer service.
bedros··on AWS EC2 FPGA Hardware and Software Development Kit
Z logic or tri-state logic are not real in FPGAs, they are chains of AND OR logic

so basically you cannot burn FPGA by making a short-circuit

bedros··on AWS EC2 FPGA Hardware and Software Development Kit
I have not read the whole FPGA HDK guide yet, but, I doubt amazon will give the designer access to pins on FPGA; they would give access to interfaces or IO blocks which connect to the pins

your design sits inside a wrapper with access to IO blocks.

inside the FPGA logic, you cannot do electrical damage, no matter how hard you try.

bedros··on Does it scale? Who cares (2011)
Many problems including not filtering user input and comments for CSS, JS, etc.

But main problem, they crumbled under heavy traffic

bedros··on Does it scale? Who cares (2011)
myspace.com failed because it could not scale

I personally switched to facebook for two reasons:

got sick of repeated errors every time I browse myspace

facebook has better album permissions, (myspace has none)

bedros··on Chatbots have struggled to live up to the hype
I feel the AI hype is similar to the cleantech hype in the 2000's

everyone jumped on bandwagon for FOMO (fear-of-missing-out)

bedros··on Deep Photo Style Transfer
awesome, wish there's no matlab requirement; can the matlab code be converted to python?
bedros··on System76 Galago Pro [video]
got Dell XPS 15" (9550) last summer, and I just upgraded from windows 10 to Kubuntu 17.04 Beta, supper happy, and everything works perfect.

wifi, sleep/wakeup, power management work right away

if you get 4K screen, you need to go settings and change font size from 96dpi to 208 dpi
