After talking to several Drupal followers during our last meetup, I realised quite a few people still don't employ version control.
I strongly consider this best practice when building a site, and thought it would be a good opportunity to go over its importance and how you can make it work for you.
Git offers several advantages:
• It's super fast
• It's easy.
• And no you don't need to be familiar with Command Line code (there are several great GUI's out there).
GIT Version Control works by keeping track of all successive changes you make to a site.
The biggest advantage of this is easily undoing any mistakes you might make along the way.
It's a great feeling to know Version Control has your back that you can roll back if something goes catastrophically wrong.
It's also a big bonus in collaborative development.
As soon as more than one person works on a project things get a lot more complicated.
What happens when 2 edits effect the same file? How do you know what's new, what's old and what's changed?
No worries, simply merge the variations and let GIT deal with the rest.
GIT is not just for the developers of this world but can be a life saver for themers, site maintainers and the like.
Most people will admit they should use it, but either don't know how or believe it's hard to integrate.
The reality is that it's actually pretty simple and once you start integrating GIT into your workflow you'll ask yourself "Why the hell did I keep using ftp" - I know I did.
FTP is so yesterday, its slow, it's cumbersome to use and it's a very manual method.
Switch to GIT, start using GIT, and never look back.

This talk is all about the Berkeley Packet Filters (BPF) and their uses in Linux.
Agenda:
* What is a BPF and why do we need it?
* Writing custom BPFs
* Notes on BPF implementation in the kernel
* Usage examples: SOCKET_FILTER & seccomp
Speaker:
Kfir Gollan, senior embedded software developer, Linux kernel hacker and software team leader.
FME Server Linux FME UC 2022 Presentation - Merline and Richard Corporate Dec...Safe Software
Many new customers migrate to Linux environments to host their FME Server installations. Linux Operating Systems often offer a lighter, faster, and less expensive platform for FME Server deployments. This presentation will work through both positive and negative considerations of migrating to Linux. It will also give you clear steps to ensure you are confident in your decision and can get the most out of your deployment, whatever it is.

2. GAZ YAKITLAR
GAZ HALİNDE
-Doğalgaz (doğal)
-Havagazı (fabrika)
-Kokgazı (fabrika)
SIVILAŞTIRILMIŞ
HALDE
-Doğalgaz (doğal)
-Propan (rafineri)
-Bütan (rafineri)
3. Gaz yakıtları;ham petrolden üretilen sıvılaştırılmış
petrol gazı (LPG),doğal gaz ve hava gazı gibi
yakıtlardan oluşur.
DOĞAL GAZ
Doğada bulunur. Metanın yanı sıra etan, propan ve bütan gibi
yüksek moleküllü hidrokarbonlar (HC) ve azot ile karbondioksit
gibi bazı yanmayan elementlerden olusmaktadır.
Doğalgaz yer kürede dört halde bulunur.
- Serbest gaz olarak petrol rezervuarında ham petrolün
üzerinde,
- Petrol yatağında ham petrolün içinde erimiş gaz halinde,
- Petrol yatağında ham petrol yoksa kapanda biriken suyun
içinde,
- 2000 metre'den daha derin rezervuarlarda basınç altında
sıvılaşmış halde bulunur.
4. DOĞAL GAZIN ÖZELLİKLERİ
-Renksiz,kokusuz,zehirsiz,havadan daha hafif bir gaz
olup,çeşitli proseslerden geçirilerek kullanılır.
-Temiz, kaliteli,güvenli bir yakıttır.Kolay yanar ve tam
yandığında mavi bir alev çıkarır.
-Hava ile %5-15 oranlarında birleştiğinde patlama
özelliğine sahiptir.
-Doğal gazın sanayide,elektrik santrallerinde ve konutlarda
kullanılır.
Dünya üzerinde Antarktika dışında tüm kıtalarda doğal gaz
üretilmektedir.
Dünyadaki en büyük üretici Bağımsız Devletler
Topluluğu'dur.
ABD,Kanada ve Hollanda ve İran da önemli doğal gaz
üreticileri ülkelerdendir.
6. SIVILAŞTIRILMIŞ DOĞAL GAZ(LNG)
Doğal gaz yüksek basınç altında hacmi küçültülmek için
sıvılaştırılır.
Nakliye ve depolanması amacıyla yapılır.
Sıvılaştırılmış doğal gaz kokusuz,renksiz,zehirleyici
olmayan sıvıdır.
Havadan ve sudan hafif bir gazdır.
