Central Nuclear em Portugal - Porque não?

Acabou de passar na SIC, uma reportagem sobre o estado das energias renováveis em Portugal, bem como o investimento do país nesta área nos próximos tempos. Falou se dos extremos impactos ambientais, que as centrais solares e eólicas vão ter nos nossos ecossistemas, sem criarem quase emprego nenhum (falou-se se não me...

Queres saber porque não? Lê isto que escrevi no outro dia tadeubento.com/…/triggering-european-immigration-…

Finland it reached negative prices because of a new reactor at the Olkiluoto nuclear power plant.

Energia nuclear = energia muito barata, as renováveis são melhores para a corrupção.

Okay, here are a few thoughts:

  • Companies like blame someone when things go wrong, if they chose open-source there's isn't someone to sue then;
  • Buying proprietary stuff means you're outsourcing the risks of such product;
  • Corruption pushes for proprietary: they might be buying software that is made by someone that is close to the CTO, CEO or other decision marker in the company, an old friend, family or straight under the table corruption;
  • Most non-tech companies use services from consulting companies in order to get their software developed / running. Consulting companies often fall under the last point that besides that they have have large incentives from companies like Microsoft to push their proprietary services. For eg. Microsoft will easily provide all of a consulting companies employees with free Azure services, Office and other discounts if they enter in an exclusivity agreement to sell their tech stack. To make things worse consulting companies live of cheap developers (like interns) and Microsoft and their platform makes things easier for anyone to code and deploy;
  • Microsoft provider a cohesive ecosystem of products that integrate really well with each other and usually don't require much effort to get things going - open-source however, usually requires custom development and a ton of work to work out the "sharp angles" between multiple solutions that aren't related and might not be easily compatible with each other;
  • Open-source requires a level of expertise that more than half of the developers and IT professionals simply don't have. This aspect reinforces the last point even more. Senior open-source experts are more expensive than simply buying proprietary solutions;
  • If we consider the price of a senior open-source expert + software costs (usually free) the cost of open-source is considerable lower than the cost of cheap developers + proprietary solutions, however consider we are talking about companies. Companies will always prefer to hire more less expensive and less proficient people because that means they're easier to replace and you'll pay less taxes;
  • Companies will prefer to hire services from other companies instead of employees thus making proprietary vendors more compelling. This happens because from an accounting / investors perspective employees are bad and subscriptions are cool (less taxes, no responsibilities etc);
  • The companies who build proprietary solutions work really hard to get vendors to sell their software, they provide commissions, support and the promises that if anything goes wrong they'll be there. This increases the number of proprietary-only vendors which reinforces everything above. If you're starting to sell software or networking services there's little incentive for you to go pure "open-source". With less companies, less visibility, less professionals (and more expensive), less margins and less positive market image, less customers and lesser profits.

Unfortunately things are really poised and rigged against open-source solutions and anyone who tries to push for them. The "experts" who work in consulting companies are part of this as they usually don't even know how to do things without the property solutions. Let me give you an example, once I had to work with E&Y, one of those big consulting companies, and I realized some awkward things while having conversations with both low level employees and partners / middle management, they weren't aware that there are alternatives most of the time. A manager of a digital transformation and cloud solutions team that started his career E&Y, wasn't aware that there was open-source alternatives to Google Workplace and Microsoft 365 for e-mail. I probed a TON around that and the guy, a software engineer with an university degree, didn't even know that was Postfix was and the history of email.

Oh yeah Oracle Cloud "Always-Free" aka the fastest way to lose all your data.

There are lots of people complaining about those situations.

Rackmount NAS Enclosure

I’m trying to plot out a home server build, and I’d like to do it in a rackmount form factor. Use case will likely be Proxmox running a NAS VM and some media services. For the NAS piece, I was thinking an enclosure with hot swap bays would be nice. Anyone have recommendations on the case/enclosure itself? I’ve seen this...

TCB13,
@TCB13@lemmy.world avatar

I don't have recommendations for a case but I would advise you to go with True NAS scale as it also makes virtual machines and is more open / less annoying than Proxmox.

Popular Hardware for Self Hosters?

I dusted off my RPI4 and started tinkering with self-hosting things and it's sparked a fire. Suddenly I have 7 docker containers running and I need more RAM, more space and I want something reliable with room to grow. I like small form factors but it doesn't need to be RPI small. Any recs for your favorite hardware under $500?

TCB13,
@TCB13@lemmy.world avatar

Or HP/Dell units second hand. Tons of companies ditch those computers after two o three years and they're still perfectly good for self hosting with Linux. We can also find really good deals on Intel 9th gen machines for around 35% of the price of all those you suggested brand new.

iPad Mini or iPad Air for a student?

I need to replace my 5 year old laptop this summer for the fall semester and I’ve decided that instead of a new computer I should just upgrade to a tablet. I’ve always loved the iPad mini for its size. It’d be extremely portable and I would honestly get a lot more use out of it other than just school work, but I’m...

Very strong. Soulseek kinda drifted to mostly high quality music because the protocol isn't a good option for large files. It would be interesting to see a Soulseek network v3 upgraded with torrent-like features...

@TCB13@lemmy.world avatar

Might not be a good deal, usally HP Mini or Dell units have better prices and better specs. You can get those for 100$ with decently modern CPUs, USB 3.0 , USB-C etc. You can find mode models with dual NVME slots, other with 1 NVME + 1 SATA that might be enough for the OP’s use case.

Actually I believe it was the US trying to ban encryption under the pedophilia umbrella. The EU seems to be more about terrorism and organized protests now.

You can run the Jellyfin webui on the rpi and have it stream the audio to it and play via the DAC. Read this: https://jellyfin.org/docs/general/clients/mopidy/#raspberry-pi-remote-controlled-speakers

Hmm.. what's your experience with running Mopidy standlone? What client are you using, does it perform better than Jellyfin?

We need more of Richard Stallman's ideas, not less (ploum.net)

Richard Stallman was right since the very beginning. Every warning, every prophecy realised. And, worst of all, he had the solution since the start. The problem is not Richard Stallman or the Free Software Foundation. The problem is us. The problem is that we didn’t listen.

@TCB13@lemmy.world avatar

No. He simply wants tech / society to fail so hard that it actually comes to true. ahaha

He kinda acts like a prophet of the doom. I’m sure you know about all those who believe that if you want something really hard, if you project / manifest it will happen. Normal people use that in order to get good thing in life, Richard Stallman seems to do the opposite with tech - manifest a bad present / future :D

I understand the movement and I'm all for it, but not for the way he typically sells his ideas and inappropriate behaviors. He behaves like an extremest environmentalist that pushes for a world where we would all be living live caveman instead of providing solutions that actually matter / make sense / keep progress rolling.

This approach is nice indeed, but have you tried to read through, let's say, Apple's error reports? People don't usually like to go over the 10000 lines of a stacktrace and end up not sending them :)

@Skooshjones @oranki @Andere I'm replying this to you all.

Here is the thing, I would love to have NC working decently but I've test almost all of their releases on the past year and the issues are always the same. Here is my main complaints:

  • Syncthing sync is robust, it doesn't fail and handles tons of files with little resources, NC uses a lot more RAM and once you get to around 1 TB of small files it will stop working randomly;
  • NC Webmail UI is poorly designed: compose window is just a small box on the center of the screen, there's no way to have the markup tools permanently show up;
  • NC Webmail UI is broken: if you select a bunch of text and turn it into a bullet list, the bullets won't even show up on NC, other e-mail clients will see them tho;
  • Integration/SSO with IMAP is cumbersome: not well documented, default configuration doesn't even handle a simple "login with the email email and password as the IMAP account" type of setup that is commonly expected;
  • WebUI is slow and fails often: if you open the browser console you'll find lots of warnings and errors.

I do have a lot of complaints related to mail but if NC is any kind of useful replacement for MS365 / Google Workplace a decently working webmail is the bare minimum. RoundCube is WAY better than what NC is currently offering.

I spent weeks researching and trying to tweak things and at the end of the day NC always performs poorly. Most of the issues seem to be related to the poorly implemente WebUI but the desktop app also has issues with large folders. Also tried the docker version, the "all in one" similar results it simply doesn't cut it.

My production setup runs on Red NAS drives and the thing just flies, always solid, stable and reliable. Here is the real production setup for around 30 users:

  • AMD Ryzen 7 5700X + 32 GB of RAM;
  • Everything containerized with LCD/LXC;
  • 2x WD RED 8 TB NAS drives (+RAID drives) for Syncthing data;
  • 2x NVMe Samsung 980 Pro 2TB for everything else (also RAID);
  • 1x 250GB Samsung 2.5 SATA SSD as boot drive;
  • Dovecot+Postfix working as mail server / "identity provider" for my users;
  • Syncthing to sync desktop machines with the server (not across each other);
  • FileBrowser for web access;
  • WebDAV access for iOS/Android clients;
  • Baikal as CardDAV/CalDAV server;
  • RoundCube for a decent webmail experience with a lot of Kolab plugins (Contacts, Calendars, Tasks from CardDAV/CalDAV);

Both FileBrowser and Baikal were modified to authenticate against the IMAP server and create accounts automatically if the username/password check out.

I'm deploying this to the user's machines via Ansible and/or iOS/macOS profiles so most things are automated by now. To onboard a new user I simply have to create the email account and then run the playbooks.

My future investments will be:

  • ejabberd with the IMAP integration and setup plugins for audio/video chat, push notifications, presence indication;
  • Integrate converse.js or Jitsi (jabber web client) into the RoundCube webmail (simply add a tab with an iframe + pass the webmail auth);
  • Explore a better multi-user Syncthing setup - possible create a small app that uses the Syncthing tech but does authentication against IMAP as well. Custom backend to automatically manage the creation of user folders and managed shares;
  • Microsoft Exchange / ActiveSync: while it might be possible most of my users are either on macOS or they don't care about Outlook / use Thunderbird or the Webmail.

Although this setup still misses some important stuff (aka replace Zoom) and I've been working on it for a while it outperforms NC in all ways so far. The investment was totally worth it.

I really hoped that NC would do all those things properly and I still try new releases but it doesn't seem to get any better.

@TCB13@lemmy.world avatar

I've made a very detailed post about what fails, when it fails etc. bellow. They sell NC as groupware replacement for MS365 / Google Workplace and it can be a lot of things but it certainly isn't that.

TCB13,
@TCB13@lemmy.world avatar

It might be, or not. For what's worth Signal might be the most secure and private solution out there, probably event safer than Matrix. I'm not going to stop using it because of that article but people should know about all sides of a story and decide for themselves.

Looking for a wiki-like application for Windows

I'm currently using a self hosted instance of XWiki on my NAS to write down long term notes just for myself. But it runs very slow with the database and limited hardware ressources. And since I only access it from my Windows PC on my LAN I figured I'd just need an application that does the same job and save the files on my NAS....
