Often Software Developers are also called Professional Googlers. This means that we need to be really proficient in it. So this thread will provide you with tips and tricks which help you to become #10xengineer in Googling. Let's start ➡️➡️➡️
1. Use quotes for "exact match" searches. Often when you search for a particular error message try searching with quotes first to get your results faster. Very helpful when you need to understand error or warning messages in logs.
2. Use '*' in as a wildcard. Use case: when searching for errors messages replace parts specific to your code(folder or package names). Also helpful you want to find a song, but remember only some words then replace the unknown part with '*'. 🎶

Va hilo sobre "soy muy grande para empezar a estudiar programación"
Hace cerca de 2 años hablando sobre si es difícil/fácil programar un groso como Ale (esacrosa) a quien no @ xq no le gusta dijo que era fácil. @malerey_ estuvo de acuerdo y yo pregunté si con 55 no estaba
un poco "pasada" como para empezar. Me dijeron que de ninguna manera, que le diera para adelante. Así conocí @Ada_ITW pero soy del interior, no me animé al online y estaba en quiebra (sigo igual) así que me puse a buscar dónde podía estudiar.
A fin de ese año me anoté en la UTN en un curso de Java, gratuito, que llevaba adelante el gobierno nacional llamado 111Mil Programadores. Durante todo el 2019 estuve cursando, cumplí 56 en medio del aula, tuve mis bajones, casi abandono pero seguí y a fin de año aprobé el examen

building a long-life (10yrs+) graph-backed web service for @pariyatti (a non-profit). we're planning to use #neo4j

i have some questions.
#python + #django support seems... weak, at best? (latest commits to `neomodel` and the django plugin are 2019/2018 with no support for neo4j 4.x)

is this a misconception on my part? i'd love a shout out from people happily building webapps with #neo4j on #python out there
#ruby and #rails support seems okay. #activegraph is a thing and there was a commit this week. the design seems sane.

i have 10-year-old rails apps, though. they... don't work. the ruby & rails ecosystem isn't really geared toward "boring things that will work in 10-20 years"

Hey new followers from the @JVMPerformance tweet! Here's a quick rundown of some of my #Java performance stuff - all free and open source for your enjoyment! 1/5
#JITWatch is a tool for understanding the decisions made by the JVM's Just-In-Time #JIT compilers when it ran your code. Learn about inlining, branches, escape analysis, lock elision and more! View bytecode and the disassembled native code… 2/5
#VMOptionsExplorer is a searchable online resource for learning about JVM switches. You can find what JDK switches were added or removed and also see when #HotSpot intrinsics were added… 3/5

#TDD, #CodeReview and #ContinuousIntegration in action - here is how with @marcandsweep we develop new features in #JaCoCo (
as an example let's have a look at…
… first we add high level "validation" test to study desired behavior, this test targets Records ( that are #JDK14 Preview Feature (,
so build fails locally, but only on JDK14 …
… yes - locally for development we have many #Java versions installed …

A Thread on "Trade Relations between Tamil Nadu and South East Asia as Gleaned from Inscriptions...!"

The Commercial and Cultural contacts between Tamil Nadu and South East Asian Countries seem to have existed even from the beginning of the Christian era!
#Sangam Literatures say that the import & export of articles between these countries had happened in great vigour through the ports located on the Coromandal coast, viz #Kollam, #Eyilpattinam, #Kaviripumpattinam, #Tondi, #Marungurpattinam (#Alagankulam), #Korkai and #Kanyakumari!
The author of the Periplus of the Erythrean Sea describes the ports of the Coromandal coast as follows. “Among the market-towns of these countries and harbour where the ships put in from Damirica and from the north, the most important are, in order as they lie, first Camara...1/2

Getting started with Want to succeed with #TDD ? Stop writing tests! @BurkHufnagel #TDD #DevNexus…
We work with software that's way more complex than a simple shape like this. Reasonable people may see the same thing in different ways, based on their perspective! @BurkHufnagel #TDD #DevNexus
You have a goal that you share with me: you want delivering better code faster

Bir yazılım geliştiricinin bilmesi gerekenlerle ilgili 15 maddelik flood geliyor.. Mümkün olduğunca fazla keywordü bir araya toplamaya çalıştım.
Hadi Başlıyoruz!

#Developer #Software #Java #code #kod #yazılım #development #computer #bilgisayar #tool #PC #IT #web #tech #data
1-Temel veri yapıları (linkedList, map, tree vb) ve temel algoritmalar (sıralama, arama vb)

Sıfırdan kodlama ihtiyacınız büyük ihtimalle hiç olmayacak. Ancak ihtiyaç anında doğru yerde doğrusunu seçebilmek için o veri yapısının veya algoritmanın nasıl çalıştığını bilmeniz şart
2- Network Temelleri

OSI Modelini ve 7 katmanı; temel protokolleri(#TCP-IP, TCP-UDP, #HTTP, #FTP), güvenlik protokollerini(#HTTPS, #SFTP, #SSL), monitoring protokolleri(#SNMP, ICMP) bilmekte fayda var. Ayrıca ağ ekipmanlarının görevlerini tanımak ve 7Layer yerlerini bilmek lazım

Little story about biases in technologies. Before I joined @wavesplatform, I thought that #scala is a very complex, non-obvious and little supported programming language, there is too much magic and you can draw ascii emojis with special characters in your code.
I heard and read a lot about troubles with #scala, and it looked reasonable. But as I dived in it (thanks to @wavesplatform deva and scala courses by @BinaryDistrict), I began to realize that these "troubles" are only my (and people in my bubble) biases.
In fact, scala is like any other popular languages with its own advantages and disadvantages. Same like #Java, #Javascript, #TypeScript, #Python in which I wrote before.

#Java's death will be due to SEO mess, lack of centralized docs, outdated tutorials & no one-stop-shop place to find it all


This site was supposed to be the answer, but it only raises even more questions. The information here is mostly marketing-related, and has pointers to other online locations, outside

Potential: very high.
Reality: waste of TLD.

The Java source, no doubt. Yet, devs who want to just learn/code Java apps will only find binaries downloads. Nothing else serves the average Java software developer. "Developer's Guide" is for contributors.

Potential: high.
Reality: confusion.

D'accord, vous l'avez bien cherché : je vais vous faire une histoire toute illustrée et chatoyante du #wax, ce tissu que (selon ce que #RokhayaDiallo a dit au #Feministival) les « blanches » n'auraient pas le droit de porter sans culpabiliser

[thread] ⤵️
3, 2, 1 : petit voyage dans le temps et nous voilà en 1637, quand la Compagnie néerlandaise des Indes occidentales s'empara du port d'Elmina sur la Côte d'Or (aujourd'hui #Ghana), détenu depuis 1471 par les Portugais.
À Elmina il n'y avait pas de wax, mais de l'or, de la maniguette et des esclaves, beaucoup d'esclaves.
Les puissants Ashantis, qui gardaient le contrôle sur l’intérieur des terres, vendent aux hollandais leurs prisonniers, surtout d'ethnie Fanti.
