evandrofisico··on They want you to forget what a film looks like
The Matrix new transfer made me really sad. It is one of my favorite movies of all time, and this new version had the colors done all wrong and in some scenes, I had the impression that the framerate was wrong, especially the bullet time and other action scenes, like they don't match the rest of the movie.
evandrofisico··on Roundcube open-source webmail software merges with Nextcloud
Implemented and integrated both at work six years ago, it is a nice combination.
evandrofisico··on We Automated Bullshit
From my limited understanding, a smaller, more specialized model could produce more accurate responses, but the main thesis of the article would still be true. Such LLMs would still be statistic prediction models, with no concept of reality.

We already know that specialist systems, such as those tried in the 80's are not very good in modeling reality, either. The thing is, using LLMs as knowledge bases or as a sort of modern oracles seems to me like using a powerful tool for something they are horrible at.

They are good enough (but not perfect) text summarizers, text translators and text transformers, but are far from the so expected "AGI" some seem to be expecting them to be.

evandrofisico··on Cursorless is alien magic from the future
It's exactly what i've been doing for the last 12 years. IBM Spacesaver keyboards + vim keybindings everywhere possible, and during the year, stretching forearms everyday.
evandrofisico··on Replace peer review with “peer replication” (2021)
Usually coming up with a idea is the easy part. For example, in my PhD project, i started with an idea from my advisor that he had in the early 2000.

Implementing the code for the simulation and analysis of the data? four months, at most. Running the simulation? almost three years until I had data with good enough resolution for publishing.

evandrofisico··on Dropbox telemetry can't be disabled
You can try to use the untrusted device functionality, the data is encrypted on the sending device. Word of caution, it is still beta, an in my experience, it is kinda hit or miss, for some folders it worked beautifully, for another, it simply did not sync after the initial configuration.

evandrofisico··on We clone a running VM in 2 seconds
The "micro" in microvms is less about size and more about resources. A typical virtual machine under Xen or KVM (para)virtualizes a lot of hardware and emulates a lot of devices, so that the operating system sees it as a normal machine.

The microVM emulates the minimal possible set of devices needed to run, such as disks and network devices, and in the specific case of firecracker, through the use of the virtio model. So it can theoretically use huge amounts of memory of a large vCPU count and still be a microvm.

evandrofisico··on U+237C ⍼ Right Angle with Downwards Zigzag Arrow
Here in Brazil we have those on bus stops.
evandrofisico··on Your computer is a distributed system
Actually, at some point in the 2.4 kernel it was possibile to do that, with single image systems, such as openmosix, that handled process discovery, computation and much more, but underneath the simple user interface it was complex, kinda insecure and so, was never abandoned and never ported to newer versions.
evandrofisico··on What Le Corbusier got wrong and right in his design of Chandigarh
Brasilia was the work of multiple architects, Lucio Costa was the main urban planner, while Oscar Niemeyer designed the most important government buildings.
evandrofisico··on Hello, Dynaboard
Same error here, firefox ESR
evandrofisico··on I went back to using a ThinkPad from 2012
At least for the x220, there are display and fan upgrades (mine uses a x230 fan), you can max ram at 16Gb (the manual says 8Gb, but 16Gb works just fine), but the CPU is soldered, so no upgrades on that.
evandrofisico··on SARS-CoV-2 infects human adipose tissue and elicits an inflammatory response
Look, even peer reviewed papers are not supposed to be treated as any kind of unquestionable truth, especially in medical sciences. It is unfortunately very common to have papers with repeatability issues or even outright wrong. Peer review just means that experienced scientists read a paper and concluded that nothing they saw was outright wrong.
evandrofisico··on Man can change his pupil size on command
I've done this since my childhood and honestly thought that everybody was able to do that.
evandrofisico··on The Expanse UI Design
It may be a case of apologetics, but autorotate only makes sense when there is a discernible gravational field, and as belters are often in low/simulated gravity, i would make sense.
evandrofisico··on Ami, a tiny cube on wheels that French 14-year-olds can drive
> about half of all Ami buyers have one car and at least two children > More than 40% of those driving Amis are under 18.

If this is accurate, those 40% under 18 are driving, but not buying. It's probable that parents are buying those cars for their teenage children.

evandrofisico··on Ask HN: What do you use for SSH key management of teams?
We centralize everything in openldap and developed a simple django app to centrally manage them.With a combination of sudo-ldap and a custom schema (OpenSSH-LPK) and using the openssh configuration AuthorizedKeysCommand we manage authentication and all sudo permissions.
evandrofisico··on Element wins deal to supply half a million licences to two German states
there is converse.js: https://github.com/conversejs/converse.js
evandrofisico··on Static Sites with Elasticsearch
You can also do the lunr index creation server side, with lib in php or python, generating a quite smaller file and also reducing processing time on the client side.

I've been developing a podcast hosting solution that parses the xml feed, generate static pages and prebuilds a lunr index, and for ~100 posts, it takes around 30 seconds to build server side and less than a second to download and and load on the client.

evandrofisico··on Running your own secure communication service with Matrix and Jitsi
tried the mobile version, because of the p2p aspect it sucks your battery dry.
evandrofisico··on Eat This Much – Automatic Meal Planner
Yes, this so much. Here in Brazil a basic meal includes a nice proportion of rice and beans, with some vegetables and for the onivores, a portion of meat.
