@rusnackor Tak toto ASN je zaujimave... Tazko si predstavit ze za tymto stala opozicia a mimovladky... https://t.co/88KpTXeYT4

@jsuchal Tak neviem ako ine appky, ale pre indie game devov tych 30% bola svojho casu revolucia. Ini distributori mali omnoho sialenejsie %.

[Zdenko Vrabel @sn3d]

@jsuchal S kazdou zmenou garnitury bude increment major verzie? To znamena ze kazde 4 roky budeme nieco zahadzovat a robit nanovo? Ci uz mam pocitat s tym, ze tato tu ostane najblizsich 12 rokov?

Ale seriozna otazka: Ako sa ma delivery vo v3.0? :)

[Zdenko Vrabel @sn3d]

@jsuchal Delivery is the king! :)

Som jediný, komu dnes táto sociálna sieť fľusá samy hnoj o dosluhujúcej prezidentke? Namiesto úcty, hejt a parodované obrázky? Čo sa stalo s touto sieťou? Toľko hnoja. A to tých ľudi ani nefollowujem. Horšie ako Facebook.

🚀 Is your Kubernetes cluster giving you DNS headaches?

Join @sn3d talk for a deep dive into #troubleshooting #DNS woes in #Kubernetes.

This session explores:
- Why DNS is like the hot water in your house (you only notice it when it's broken!)

@jsuchal Kazdemu co tliacha o mieri v zmysle nech sa UA vzda uzemia - len tak bez nicoho, tak tym odporucam tento navrh dat na papier, a ist to odprezentovat tym, co prezili Bucu, Mariupol atd.

[Zdenko Vrabel @sn3d]

@jsuchal Podla mna vobec neporovnavas neporovnatelne. Asi si trafil na NP problem zmluvneho prava :) Mame zmluvnu slobodu ktora zarucuje ze si zmluvneho partnera mozeme vyberat. Na druhej strane je tu siroko definovany zakaz diskriminacie - Trojsky kon. Toto je na pravnicku konferenciu :)

@bejulik Nieje to lichotive ale v Snine ani v Medzilaborciach neziskal dalsich takmer 600k volicov. Tieto volby vynimocne odmietam narativ ze vychod volil blbo (Poprad, Presov). Uprel by som zrak skor na juh...

[Zdenko Vrabel @sn3d]

@jsuchal Asi budem jediny co tu pojde proti prudu ale ... Ten argument: Lebo Estonsko? Ale preco nie Finsko? Norsko? Preco sa do toho nehrnu? Ok, je tu Estonsko. Ale otazka znie: Aky je prinos? Lebo zatial sa ukazuje ako nic moc. Ta ROI tam zatial nedava zmysel. Ci?

[Zdenko Vrabel @sn3d]

@jsuchal Toto je podla mna slepa cesta. Osobne problem sw. engineeringu nevidim ako problem pisania kodu. Su omnoho zaujimavejsie vyuzitia. Akurat vcera som cital tento zaujimavy wp: https://t.co/GMayL3yva0 Pride mi to ako lepsia cesta.

[Zdenko Vrabel @sn3d]

But I have to admit, this discourse produce some good tech. content on this network. Finally :) DNS was always an interesting topic, which is not about true/false :)

[David Flanagan @rawkode]

Let's chat about the latest Kubernetes discourse, where some people decide to call it out for using DNS for service discovery.

First, DNS for service discovery is just fine; but not without its challenges.

Let's explore a little.

[Zdenko Vrabel @sn3d]

Yeah and fun is: most of them are NXDOMAIN, they usually bypassing caching :)

[Alex Ellis @alexellisuk]

@christianposta @ibuildthecloud If don’t qualify the name, you get up to 10-20 DNS queries from the Pod every time an inter service request is made and that hammers CoreDNS under heavy load. Ask me how I know.

Maybe it’s different if you’re on Solo/Istio. Is that the point being made? 🤷

[Zdenko Vrabel @sn3d]

@jsuchal Neblaznite. Neruste to. Ak by toto niekto zrusil, tak v Kosiciach by druha najvacsia firma ohlasila hromadne prepustanie a mali by sme tu nezamestnanost na urovni 20%.

[Zdenko Vrabel @sn3d]

@MSimecka Sa mi pacia ti ceski boti tu :) Ucty zalozene okolo Augusta minuleho roku a uz 25k prispevkov :)

[Zdenko Vrabel @sn3d]

Ja neviem. Kedy uz konecne prestaneme mladych devov oblbovat dedicnostou? Kedy sa zacne ucit 'composition over inheritance'? Potom vsade mame ten Javovsky overengineering. Hovorit o dedicnosti a lahkej udrzbe - to uz hranici z dezinformaciami.

eBPF is great, but this is a moment when eBPF is wrong hammer. Istio's ztunnel make perfectly sence here. eBPF is shining in low-level networking but this is probably too complex for in-kernel and require some userspace stuff https://t.co/EKrpEUnU7i

What is something that helped you take a significant leap in your career?

Technology or piece of advice... 💬

[Zdenko Vrabel @sn3d]

@jsuchal Delivery is the key...

[Zdenko Vrabel @sn3d]

@jsuchal Dufam ze development v cloude rychlo zomrie. Nepoznam nic drahsie a zbytocnejsie pri vykone dnesnych laptopov.
