A cheaper and safer agentic AI workflow

I recently tried agentic coding for real. It cost $0.034 and finished in 3 minutes. It made two mistakes. In my personal human attempt, I took an hour, and made four mistakes. Cheaper model services I heard about GLM-5.2, and a lot of benchmarks are saying it's on …

Prețul apartamentelor în România

Sunt în căutarea unui apartament (dar nu mă grăbesc), și prin urmare încerc să învăț cum se evaluează unul. Mă întrebam cum afectează poluarea prețul apartamentelor. Am intrat pe calitateaer.ro și am reușit să conving sistemul să-mi dea rapoarte cu poluarea cu particule până la 10 microni (PM10 exprimat …

On Saudi Arabia

I have recently seen a video by Wendover Productions about the Kingdom of Saudi Arabia. It presents that the Kingdom needs foreign investment to be able to thrive past peak oil . But the leaders take extreme offense and kill people based on what they write about the Kingdom. So, yours …

On surveillance through face recognition

A year ago , a Black man was arrested for theft. The evidence was crummy face-recognition coupled with a security guard's ID who had not seen the person, only a security tape. A few months ago , some civil rights organizations filed a lawsuit against the Detroit Police Department for the wrongful …

Indice preț sandwich 2021

Acum aproape 3 ani am postat despre prețul unui sandwich . Cum am auzit la știri recent că s-au scumpit alimentele , am decis să verific prin a actualiza acest index. Azi nu am găsit în magazin pâine Pave de 500g; aveau doar la 1kg, cu 4.40 RON. Am găsit și …

SymReg: approximate functions using Symbolic Regression

I recently made SymReg . It lets you discover mathematical expressions that explain some data based on some other data. The code used for this blog post is in this notebook . Let's try it on a sine wave, in spite of the fact that it does not have a sine building …

Alegeri locale în Cluj-Napoca 2020: opinii

Update 2020-09-26 23:24 : E mai complicată legea, locurile nu se distribuie proporțional cu voturile. Trebuie să treacă de pragul de 5% (sau 7% pentru alianțe de două partide). Detalii într-un comentariu pe Reddit . Îmi cer scuze. Va fi un singur tur, după cum propagandează puterea . Acest lucru înseamnă că …

The Grand Unified Theory of Software Architecture

Take Uncle Bob's Clean Architecture and map its correspondences with Gary Bernhardt's thin imperative shell around a functional core, and you get an understanding of how to cheaply maintain and scale software! This is what Mr. Brandon Rhodes did. It's not every day that I find such clear insight. I …

Despre votul electronic

Sunt un programator. Deocamdată mă tem de votul electronic, și o să vă prezint câteva riscuri. O bază de date centralizată Dacă o astfel de bază de date ar aduna voturile, aceasta ar fi cel mai vulnerabil punct. Orice persoană ce are acces la acel sistem poate vedea cine a …

TDD Revisited - pytest (updated 2020-09-03)

Updated 2020-09-03: Statement on coupling I was recently blown away by watching some of Uncle Bob 's Clean Code presentations (make sure to check out his blog ). Of particular focus was his demo of Test-Driven Development , which when done right, reduces defects, development cost, and maintenance cost of software. In …

Cryptocurrency security

In my review of cryptocurrencies , I mentioned that Bitcoin Cash offers "relatively less security compared to Bitcoin". What did I mean by that? What are the various kinds of security that a cryptocurrency offers? How to enhance them and avoid compromising them? I will address the following questions: What does …

Don't use VPNs

I argue that VPNs are bad for the user, especially if the user is a dissenter from the status quo.

Bitcoin price predictions

Knowing that the next Bitcoin "halvening" will shrink inflation to half yet again next month (I estimate it'll be the 23rd of May), I was curious to see what's in store for the price of Bitcoin. Currently, the supply inflation is below 4% per year, according to this pretty chart …

The story of Hong Kong: mapping search engine bias

A search engine has an immense influence upon the searcher. Let's explore the story of Hong Kong. Hong Kong was a UK colony before being ceded back to China, who declared it will let Hong Kong "enjoy a high degree of autonomy, except in foreign and defence affairs which are …

Price gouging during disasters

When disaster strikes, like a fire, flood, hurricane, or an epidemic , and utilities and supply chains get disrupted, you might see much higher prices for goods that yesterday were cheap. This is called price gouging . For instance, in 2017 after hurricane Harvey struck Texas, in some locations gas prices shot …

Frequency of bug/fix commits

I shared my previous post on Reddit, and I got some very useful feedback which pointed out the irrelevance of what I was measuring (and also a scientific paper pointing out many statistical errors in a "real" GitHub study). So, I figured I'd measure something more relevant: bugs. Caveats Sadly …

Programming languages

I decided to review some programming languages, by comparing their popularity with their Rosetta Code implementation terseness. I measured terseness as the average of implementations' estimated zipped code filesize. Update 2021-01-17 : After another enlightening Reddit discussion , I realized an even worse caveat of just looking at Rosetta Code snippets is …

Angajat, PFA, sau SRL?

Să zicem că vrei să lucrezi în România. Ce forme legale sunt, și ce impozitare au? În aceste calcule am presupus că: ești un neplătitor de TVA (deci nu poți nici deduce TVA din achiziții) nu ai cheltuieli deductibile (care ar reduce impozitul pe venit) salariul minim e de 2080 RON/lună impozit pe venit de 10% (sau 3% pt. SRL) CAS e de 10% CASS e de 25% impozitul pe dividende e de 5% se aplică…

How to protect your personal data

On the surface, CDNs (Content Delivery Networks) present a great way of speeding up the loading of websites. Without a CDN, requests take longer for users that are far away network-wise , but not a lot longer if users are near the server (perhaps on the same continent). Here are some …

Why Android is falling apart

If you're an Android user, you've probably seen more and more "glitches" lately, where you get delayed notifications, events, or even alarms. My experience with a Samsung Galaxy S6 App killing Firebase & notifications Blocking WiFi scanning for other apps while Google Location Services still scans everything Open Source is not …

Opinii despre candidați la președinție

Am luat fiecare candidat în ordinea inversă a semnăturilor, și am săpat să văd cum și-a folosit puterea, dacă a avut-o vreodată. De ce ordinea inversă? Pentru că avem două tururi, și vă recomand să votați cu candidatul cel mai potrivit vouă, pentru a profita la maxim de vot, și …

Analiză partide - partea 3

Am refăcut analiza de la partea a 2-a a acestei analize, și am dus-o mai departe. Metoda calculării votului normalizat (comparabil între partide) era cam ciudată (abținerile erau considerate diferite de lipsa unui vot sau de absențe). Ca urmare, apăreau diferențe artificiale irelevante dintre partide. Am decis să iau ca …

Analiză partide - partea 2

În continuarea postării precedente , voi continua să analizez ce fac partidele. De data aceasta, nu voi încerca o analiză obiectivă, ci interpretez eu ceea ce fac. Voturi specifice PSD: 22732: 'Ceva despre comisii permanente; dar nu am înțeles ce după ce am citit modificarea propusă ', 22764: 'Modificarea ordinii de vot …

Analiză partide - partea 1

Am încercat să îmi dau seama eu cu cine votez... hâc ! Nu știu de unde să încep să caut date cât de cât obiective despre candidații la președinție. Dacă aveți sugestii, vă rog să lăsați un mesaj! În lipsa acestora, am decis să analizez partidele cu care aceștia sunt afiliați …

Review of Cryptocurrencies

Hello again, dear reader! As I promised you last post , I have reviewed some cryptocurrencies, and I will publish my fact-based heavily-biased opinions on them. Take this post with a grain of salt, and mind that investment (or speculation) is risky. However, I hope you find it useful. Bitcoin Bitcoin …

Intro to Cryptocurrencies

A friend of mine recently asked me about cryptocurrencies. I gave him the short story, but I'll post the long story here as well, for anyone interested. What's the point? In its most basic form, a cryptocurrency is a list of balances in accounts. Only people that have the password …

Caring for your hardware

Thermal shutdown I started playing some games on my Debian laptop. After some time of intense fan blowing, the laptop shut down. I figured this was likely a thermal shutdown - the device turning itself off to protect itself. I started monitoring the temperature - and it was getting to 100ºC at …

On Zeitgeist, the Venus Project, and the "Resource Based Economy"

The Venus Project is a vague "solution" to current problems of civilization. They claim that through a "Resource Based Economy" , coupled with advanced science and engineering, everyone can reach a very high standard of living. This "Resource Based Economy" claims that "all resources must be declared as the common heritage …

GDPRanoia

Updated 2019-11-18. The GDPR is legally convenient, in case you are a private person, and want the illusion of control over data gathered from you. However, when considering its actual impact, and looking at it from different perspectives, it can appear strange, and perhaps even scary. Broad definitions I had …

Don't buy Apple products.

Apple denies any possibility of data recovery after your device is not bootable. This is plainly false. On top of that, they ban people who know how to recover your data from their forums. Jessa Jones was banned from the Apple forum for offering support to people. It's almost as …

EU Copyright Directive

The EU Parliament recently adopted a new copyright directive which makes a site owner responsible for what the site's users post (Article 17 AKA former Article 13). As with most legislation nowadays, it must have been initiated by some group which would benefit from it - as opposed to "good" legislation …

The more I think about tech giants, the more I want to use self-hosted services. On this blog, I will talk about what I want to do with my life. The first and most important item on my list is self-expression . When you use a private service like Facebook, Google …
