• ⁨Comment⁩ on ⁨My thoughts shopping around for a wiki solution⁩ ⁨⁨3⁩ ⁨days⁩ ago⁩:

  Xwiki is missing.

  For me after a similar search it is the current winner. Even though it has it’d downsides.

  Pro:

  • It is well tested in a enterprise enviromentand mighty

  • It has all the features I personally found important for a company wiki, e.g. approval, versioning, templates, collaboration, integration api,etc.

  • It is fairly easy to extend it yourself

  • It is easy to host subwikis within the same installation with a self defined grade of independence - which is great for customer facing things,large projects with externals,etc.

  • The development community is big and enterprise focus and release cycles are good. (Not like a certain .js) There is very little chance it will stall suddenly as the wiki has been adopted by a lot of large companies which seem to support it.

  Contra:

  • It is written in bloody Java

  • (even though this sentence is redundant with the one above) It is a resource hog

  • The look and feel is a bit outdated unless you customise it yourself. Then it is reasonably good.But there are basically no paid templates,etc.

  • Paid support is only available through third parties it seems.

  Nah, OP is just a troll. Most European countries by now have legislation to mandate them or are currently introducing these. All of them heavily advise them.

• ⁨Comment⁩ on ⁨YSK Your smoke detectors should be replaced every 7-10 years⁩ ⁨⁨6⁩ ⁨days⁩ ago⁩:

  This is plain WRONG and DANGEROUS.

  The issue is NOT the Americum but the natural degration of the photoelectric cells and the accumulation of dirt within the test chamber.

  Even before that time the risk for false alarms is increased substantially by degration before the chances for sucessful alarming decrease rapidly. Due to that they actually withstand aging actually worse than ionisation based devices.

  Sientific sources?

  Personal recommendation: Start with a selfhosting support software like Casa, Yuno or (my recommendation) Cloudron. Start hosting the app there with frequent backups and occasionally export into regular Bitwarden as a failsafe.

  And when you are comfortable switch over to properly self hosted Vaultwarden.

• ⁨Comment⁩ on ⁨What's a good printer for ASA filament?⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  So,here’s another update almost a month later.

  Am I still happy with the U1?

  Yes.

  Am I happy about everything? No.

  A few things that tend to get on my nerves.

  • The lack of filament cutting is annoying and massively delays changing filaments. Argh.

  • The filament roll placement is shit,especially when printing ASA and similar filaments that need to be really dry. (PEBA) Placing them out in the open turned out to be an issue, especially when you use a spool for frequent shorter prints. (E.g. one part of 5h today,another tomorrow,etc.) Especially annoying with the point above which makes simply chucking away four spools time consuming. I migitated that by using a almost closed system of containers - but I suffer from issues with the filament feeders occassionally as the axles for these tend to be an issue.

  • ASA has shown mixed results with the improvised hood. (Aka a plastic bin, not fitting properly, holes between it and the printer covered with tape). After looking at it with a thermal camera its clear why: The large ventilation holes on the sides let a lot of air go through (tbf,the current location here is a bit exposed) and the headpad is not heating up fully uniform (but more uniform than the P1S in comparison). So I blame the ventilation holes. Smaller ASA prints are not a problems, larger ones are - especially with more unforgiving filaments. (E.g. Spectrum 275 works well, Black Forest doesn’t, Extrudr is somewhat okay) For testing purposes I tried to print with the holes covered and that worked well. But this creates it’s own issues - for PLA you need way more ventilation as the fans are FAR less powerful (even though louder) than in the P1S.

  BUT I will improve things

  • The acrylic glas panes arrived so I will install a proper hood now.
  • The additional tempsensor will arrive tomorrow. I want trustworthy independent temperature values in the case before I block
  • AND,biggest news, the Panda Breath has arrived and BIQU has published a manual how to install it perfectly into the U1. Will do so soon and expect most of the issues to be solved by that.

  So this sounds negative,right? It isn’t! I am still very happy and the U1 solves a fuckton of isssues I had with the P1S. Multimaterial,automation, filament tracking, etc. For PLA my print results (with a bit of tuning) are on par with the P1S OR better for things that need support. (As you can use different materials far better than with AMS) And finally having proper clipper back and the options of the extended firmware is nice.

  Funny thing: I got two aftermarket print plates from AliE and they are both providing much better grip than the snapmaker original.

• ⁨Comment⁩ on ⁨Are you selfhosting your business with employees? What are the software that you are using?⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  We kind of selfhost almost everything - while we operate a small server ourselves, the main burden is on a dedicated server setup. Basically a FreeIPA+Authentik+OpenCloud Stack as a base,with Redmine, Kimai, Zammad, Matrix, Jitsi and a few mode apps.

  Backups are done onsite and to three different offsites, including cold storage backups.

  As we all work fully remote this setup is also fairly adaptable and the switch to a (almost fully) Linux shop went far better than expected - my staff is fairly content with their setup (afaik).

  The only thing I refuse to selfhost are email and VoIP.

• ⁨Comment⁩ on ⁨what does your "workshop" look like?⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  My 3D workshop? A somewhat large custom fitted closet. The printer sits on a extending/sliding base and there are shelves with the filament boxes (I use resealable containers).

  The printer is fully enclosed (adapted U1 with a chamber heater, a chamber air filter), but the cabinet itself can also be ventilated with a exhaust going through a custom made filter array (HEPA and activated charcoal. A mate of mine is builds those for a living/has a PhD in it, so it is somewhat sophisticated) or unfiltered. Additionally I installed a light and various temperature probes in it.

  These days a small display should arrive that I want to fit outside it, so I can control the printer, vents,etc. from there, via Home Assistant. In the long term I will also slowly replace the cheap hygrometers I now have with ZigBee ones so I can list all humidities in the display.

  Additionally I have a Chitu E1 and a Gratkit for drying. While the Gratkit fits, I haven’t found a good space for the Chitu yet.

  Next to the closet is a height adaptable desk I use for electronics and things like that so I have my post-processing tools there as well.

  Still mediocre compared to OPN/pfsense, IPfire, VyOs,etc.

• ⁨Comment⁩ on ⁨Looking for FOSS server monitoring UI⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  I must admit I can’t find the exact guide I used anymore. Especially not a English one.

  But the official guide should help you: www.zabbix.com/de/integrations/proxmox

  I think whatever I used was pretty close to it. If you have any issues send me a DM.

  (And tbf, I use both the Agent2 and the API in a perverse mixture. And for some nodes IPMI on top of it. It’s really kinky,but it does the job)

• ⁨Comment⁩ on ⁨What's your opinion on Ubiquiti/Unifi gear?⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  Absolutely, but unlike Ubiquiti they did not keep them under the rug that long. (Nevertheless: Both are shit for firewalling. Put a OPNsense before it?)

• ⁨Comment⁩ on ⁨Looking for FOSS server monitoring UI⁩ ⁨⁨3⁩ ⁨weeks⁩ ago⁩:

  Zabbix is extremly nice.

  Why?

  • API Monitoring for Proxmox and Docker/Podman. Aka "you don’t need to setup monitoring for every container/LxC/VM. Do it once for the host,then everything gets autodiscovered.

  • Active and passive agents as well as SNMP, IPMI,etc. can be combined as you like. Also does Website/service/application/database monitoring, SSG/Telnet checks and nowadys can even do Prometheus and MQTT/Modbus

  • The proxy is really really worth it. It collects data from nodes you do not want exposed and relays them to the server. This includes all kind of inputs and is really easy to setup.

  • Due to it being around for two decades there are a shitton of templares for devices - and it’s fairly easy to do your own.

  • Unlike other systems (cough checkmk cough Grafana) there are no features that are only available to paying customers.

  The most major downsides are the fact that it’s moderately to fairly ressource intensive to run in a small setup(but does consume less than others in large Setups) and it’s far less flashy dashboards. (Which are still powerful,though)

• ⁨Comment⁩ on ⁨What's your opinion on Ubiquiti/Unifi gear?⁩ ⁨⁨3⁩ ⁨weeks⁩ ago⁩:

  Not a fan. Absolutely not.

  They had multiple security incidents which they kept under the rugs for a long time, they have the tendency to EOL devices without warning (which then means you need to replace your sometimes 9month old device or your whole enviroment can’t be updated), their lock-in into their ecosystem is much more complete as they can’t be used properly without their enviroment.(e.g. Omada devices can work without the Omada stuff, with Unifi you will always need a controller for some functions).

  So if you realy need SDN features like Unifi look at Omada,otherwise Mikrotik is a solid alternative. (And OPNsense for firewall)

• ⁨Comment⁩ on ⁨System Redundancy⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  My company is a part of critical infrastructure and we provide consulting in disasters (e.g. how to get a hospital back up and running). So we fall under European legislation to have certain precautions. And as I colocate in my companys rack…it’s easier. As the rack is in a room I rent to my company. (We are small and I am the founder,that makes it easier)

  But yeah, we put a bit of thought in it. Waiting for Iris2 finally materialise so I can get rid of LTE finally.

• ⁨Comment⁩ on ⁨System Redundancy⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  I have a LTE Backhaul,but admittedly if the firewall itself craps out I would also be offline - but I can at least reboot it via a plain old GSM power plug. That thing does not directly reboot the firewall,though, but brings up a old raspberry (usb boot,I don’t trust sdcards) which then checks if outside connectivity is still available (so if the GSM power plug gets compromised it’s not an issue) and if not tries a shutdown or,if that is unsucessful, a powercut of the firewall. If that also doesn’t work it triggers a dry contact in the GSM plug which leads to the plug sending out a SMS so I know I am fucked and need to get someone with a key to the rack.

• ⁨Comment⁩ on ⁨How long does it take for pregnancy to become noticeable?⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  Paramedic here with specialised delivery training. Delivered around 30 babies probably. Saw a high three digit number of pregnant patients.

  You can’t reliable say that. Until you see the kid.

  And I don’t mean the cases were the mother is blocking out the pregnancy mentally until she is crowning. (But tbh, it’s one of the most cherised moment of everyone in my profession if you have the “I am not pregnant,you idiot!” “Ma’am, I literally can see the hair of your baby coming out…oh and here’s the rest of the bub”-discussion)

  I literally had a aquaintance not recognise her pregnancy (and she had been pregnant before) until she went to hospital for stomach pain. I saw her the weekend before and did not recognise the pregnancy. And,yes, the baby was full term. Happens, especially if the uterus is not in its usual place.

  In other people you see it after 8 weeks (and well,it is often not the belly that is the first indicator which grows suddenly).

  Other people look like "13 months pregnant with triplets"at the beginning of their second trimester.

  Anyway: What is the reason for your question? (And: If you or anyone needs support in that case write me a messge. More than happy to guide you in the right direction if you are in a tight spot.)

• ⁨Comment⁩ on ⁨World's largest particle accelerator begins warming thousands of local French residents with waste energy from the 16-mile Large Hadron Collider⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  Datacenter heat is actually a very good source for local heating networks and a lot of European countries either already mandate to consider it when feasible, have introduced legislation that will make it mandatory over the next years or are at least supporting it financially.

  It’s actually fairly common to do so for a long time here - from waste incineration, steel mils, nuclear plants, etc.

  Personally I heat my office from my server rack and my old job did heat one of their office buildings from the heat generated by the data center in the basement. (And funny enough also did partially cool it from that source)

• ⁨Comment⁩ on ⁨Looking for a European news service⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  Excellent points,just a few things added:

  • Sueddeutsche has a english section as well that also includes some articles from the Atlantic

  • TAZ.de is also an option,it’s free but mostly German (but also has a small English section). It’s bit like the Guardian but more left leaning.

  • heise.de is a reasonably good news source for tech news both in German and English

  • France24.com is a good english speaking choice for world news,especially as they often cover topic not heavily covered by other news outlets,e.g. things in Africa,Asia,etc.

  • Sadly only German speaking but ver good: Der Falter (falter.at) from Austria.

  There is a directory of European newspapers at newspapers-europe.eu.

  Another protip: You can get registered in a library and a lot of them provide free access to a LOT of magazines to read for free online. And you often don’t even have to live close to said library to register and can register online.

• ⁨Comment⁩ on ⁨YSK that a general strike is one of the most effective ways to push for change. There is a general strike in the works across the US for this Friday.⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  Technically they are not illegal here - they are just not protected under the (very strong) strike protection laws.

  So workers in Germany could go into general strikes but they would not be covered by strike law and therefore just absent from work. Which of course is an issue - but in case of a proper general strike, what are they gonna do, fire everyone? Especially in times when there are countless positions open?

  So one would only get into trouble work wise,but not otherwise - one would not get arrested, cannot get sued (besides a very limited scope worklaw wise),etc. Only certain kind of civil servants (similar but not as common as the Pubblico Impiego in Italy) will get in trouble if they go on strike. E.g. cops, fireman, teachers, municpial clerks (but not muncipial workers and not all kind of clerks),etc.

  Which I find somewhat fair as our strike protection laws are far reaching (afaik even a bit further than in Italy) and the employer is often as fucked by politics as the staff. So it’s a somewhat tradeoff I personally can live with. (Seen from my time as an employee. These days I am a small employer,but as left as ever,and from a employers point of view wouldn’t care to much - but the nature of my business supports it.)

• ⁨Comment⁩ on ⁨What's a good printer for ASA filament?⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  Sooo…as promised a feedback about the U1:

  • it did print a small (10x10x5mm) test cube without issues even without a hood. (Black Forest Filament ASA HF)

  • with a improvised hood that was anything but airtight I achieved 57° degrees inside the hood (measured with a temp probe 10cm above the plate). (I literally just chucked my kids toy basket on it)

  So. With a proper hood it should be no issue to print ASA in larger prints. But there are two downsides, well,one. The other one might be helpful.

  • There is very little room inside the build chamber that is not used, very different from the P1S for example. That will make it hard to just chuck a heater in - it very likely would need to go in the top cover or somewhere else. I have ordered the Panda Breath,but that will take another month to arrive.

  • The printer is very open in the bottom.(Literally jusf grated metal) On one hand this might be an issue if too much cold(or dusty) air comes in through that or too much air goes out through that that is then unfiltered.

  So my current idea is to actually use the space below the printer for heating or to remix the hood from srinn to have space for the Panda Breath.

  You’re so right. I mean…I used to work with people who were K9 handlers and anyone who even brought his dog in a situation that would allow direct contact would be scrutinised. Repeatly? You are no longer a K9 handler and probably no longer a officer.K9 training is expensive and a handler who let’s that happen would not be in control obviously. But training here is done on a state level (we have no local law enforcement in my neck of the woods), regulated on a national/federal level and passive signaling is preferred these days anyway.

  So… As you said… Even a dog getting an OD would be so crazy here it would probably make national news if the media got wind of it.

  Crazy.

  Have a look at Agent DVR. Works locally and the “pro” features that one would need to pay for are basically just Plugins. Everything else works nice without it. Additionally it accepts basically everything you throw at it camera wise and is far easier to configure than frigate, also has a (good) HA integration and is extremly mighty if your system grows over the years.

• ⁨Comment⁩ on ⁨What are good option for self hosting home security camera?⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  Did you just seriously recommend port forwarding to a NVR login? Even worse with a consumer grade router? With HTTPS,non Standard Port and a strong password as the only security tips?

  Please,people,for the love of god: Don’t do that. Really. Don’t. This is really bad advice,sorry.

  Unless you are very very sure that your NVR solution is impecable in terms of security (none are), you are 100% sure you stay up-to-date all the time (including reviewing updates for issues) and have additional measures like fail2ban, IDM/IDS,etc. in place this is a very bad idea. HTTPS is only helping in terms of password transmission/spoofing,which is an unlikely vector here, a non standard port doesn’t help one bit here(have a bit of fun with shodan and see yourself) and while a strong password helps it only helps if the auth of the system and the OS below itself is watertight - a hard task.

  It is always a bad idea to port forward unless you really really cannot avoid it.

  Use a VPN - as you said, wireguard.

  Yeah. But with any hood (aka the famous ikea hood) it seems to ve already working reasonably good.

  In theory the P1S is also not good for ASA due to it’s lack of chamber heating.

  In reality I print 50% of my prints with ASA and besides some preheating via plate it is a walk in the park. (Which by now is automated via Home Assistant for me).

  And of course there are always external heaters available. A friend has his P1S in a basement that has 5° all year round. A 30€ heater did it. Simply chucked into a corner and done.

  But yeah. Out of the box it is an issue,yeah. I will report back.
