    that a moderately clever human can talk them into doing pretty much anything.

    besides that LLMs are good enough to let moderately clever humans believe that they actually got an answer that was more than guessing and probabilities based on millions of trolls messages, advertising lies, fantasy books, scammer webpages, fake news, astroturfing, propaganda of the past centuries including the current made up narratives and a quite long prompt invisible to that human.

    cheerio!




  • after looking at the ticket myself i think the relevant things IMHO are:

    • a person filed a bug report due to not seeing what changes in the new version caused a different behaviour
    • that person seemed pushy, first telling the dev where patches should be sent to (is this normal? i guess not, better let the dev decide where patches go or -in this case- if patches are needed at all), then coming up with ceo style wordings (highly visible, customer experience of untested but nevertheless released to live product is bad due to this (implicitly “your”) bug)
    • pushiness is counterparted by “please help”
    • free-of-charge consulting was given by the one pointing to changes likely beeing visible in changelog (i did not look though) but nevertheless it was pointed out to the parameter which assumes RTFM (if docs were indeed updated) that a default value had changed and its behavior could be adjusted by using that given parameter.

    up to there that person -belonging to M$ or not (don’t know and don’t care) - behaved IMHO rather correctly, submitting a bug report for something that looked like it, beeing a bit pushy, wanting priority, trying to command, but still formally at least “asking” for help. but at that point the “bug” seemed to have been resolved to me, it looks like the person was either not reading the manual and changelog, or maybe manual or changelog lacks that information, but that was not stated later so i guess that person just did not read neither changelog nor manual.

    instead - so it seems to me - that person demanded immediate and free-of-charge consulting of how exactly the switch should be used to work in that specific use case which would imply the dev looks into the example files, maybe try and error for himself just so that that person does not need to neither invest the time to learn use the software the company depends on, nor hire a consultant to do the work.

    i think (intentional or not) abusing a bug tracker for demanding free-of-charge enduser consulting by a dev is a bad idea unless one wants(!) to actively waste the precious time of the dev (that high priority ticket for the highly visible already live released product relies on) or has even worse intentions like:

    • uploading example files with exploits in them, pointing to the exact versions that include the RCE vulnerability that sample file would abuse and the “bug” was just reported cause it fits the version needed for exploitation and pressure was made by naming big companies to maybe make the dev run a vulnerable version on it on his workstation before someone finds out, so that an upstream attack could take place directly on the devs workstation. but thats just creating a fictive worst case scenario.

    to me this clearly looks like a “different culture” problem. in companies where all are paid from basically the same employer, abusing an internal bug tracker for quick internal consulting would probably be seen as just normal and best practice because the dev who knows and is actually working on the code is likely to have the solution right at hand without thinking much while the other person, who is in charge of quick fixing an untested but already live to customers released product, does not have sufficient knowledge of how the thing works and neither is given the time to learn or at least read changelogs and manual nor the time to learn the basics of general upstream software culture.

    in companies the https://en.m.wikipedia.org/wiki/Peter_principle could be a problem that imho likely leads to such situations, but this is a guess as i know nobody working there and i am not convinced that that person is in fact working for the named company, instead in that ticket shows up a name that i would assume to be a reason to not rely too much about names in the tickes system always be realnames.

    the behaviour that causes the bad postings here in this lemmy thread is to me likely “just” a culture problem and that person would be advised well if told to learn to know the open source culture, netiquette etc and learn to behave differently depending on to who, where and how they communicate with, what to expect and how to interact productively to the benefit of their upstream too, which is the “real price” all so often in open source. it could be that in the company that rolled out the untested product it is seen to be best practice to immediately grab the dev who knows a software and let him help you with whatever you can’t on your own (for whatever reason) whenever you manage to encounter one =]

    i assume the pushyness could likely come from their hierarchy. it is not uncommon that so called leaders just create pressure to below because they maybe have no clue of the thing and not want to gain that clue, but that i cannot know, its just a picture in my head. but in a company that seems to put pressure on releasing an untested product to customers i guess i am not too wrong with the direction of that assumption. what the company maybe should learn is that releasing untested and/or unfinished products to live is a bad habit. but i also assume that if they wanted to learn that, they maybe would have started to learn it like roundabout 2 decades ago. again, i do not know for what company that person works -or worked- for, could be just a subcontractor of the named one too. and also could be that the pushyness (telling its for m$, that its live, has impact to customers etc) was really decided by someone up the latter who would have literally no experience at all on how to handle upstream in such situations. hierarchies can be very dysfunctional sometimes and in companies saying “impact to customers” sometimes is likely the same as saying “boss says asap”.

    what i would suggest their customers (those who were given a beta version as production ready) should learn is that when someone (maybe) continously delivers differently than advertised, that after some few times of experiencing this, the customer would be insane when assuming that that bad behaviour would vanish by pure hope + throwing money into hands where money maybe already didn’t help improving their habits for assumingly decades. And when feeding everhungry with money does not resolve the problems, that maybe looking towards those who do have a non-money-dependant grown-up culture could actually provide more really usable products. Evaluation of new solutions (which one would really be best for a specific usecase i.e.) or testing new versions before really rolling them out to live might be costly especially when done throughout, but can provide a lot of really high valueable stability otherwise unreachable by those who only throw money at shareholders of brands and maybe rely on pure hope for all of the rest. Especially when that brand maybe even officially anounced to remove their testing department ;+) what should a sane and educated customer expect then ? but again to note, i do not know which companies really are involved and how exactly. from the ticket i do not see which company that person directly works for, nor if the claim that m$ is involved is a fact or just a false claim in hope for quicker help (companies already too desperate to test products before live could be desperate again in need for even more help when their bad habits piled up too long and begin falling on their heads)


  • the xz vulnerability was done through a superflous dependency to systemd, xz was only the library that was abused to use systemd’s superflous dependency hell. sshd does not use xz, but systemd does depend on it. sshd does not need systemd, but it was attacked through its library dependency.

    we should remove any pointless dependencies that can be found on a system to prevent such attacks in future by reducing dependency based attack vectors to a minimum.

    also we should increase the overall level of privilege separation where systemd is a good bad example, just look at the init binary and its capability zoo.

    The company who hired “the” systemd developer should IMHO start to really fix these issues !

    so please hold your “$they have fixed it” back until the the root cause that made the xz dependency level attack possible in the first place has been really fixed =)

    Of course pointing it out was good, but now the root cause should be fixed, not just a random symptom that happened to be the first visible atrack that used this attack vector introduced by systemd.


  • i am happy to have a raspberry pi setup connected to a VLAN switch, internet is behind a modem (like bridged mode) connected with ethernet to one switchport while the raspi routes everything through one tagged physical GB switchport. the setup works fine with two raspi’s and failover without tcp disconnections during an actual failover, only few seconds delay when that happens, so basically voip calls recover after seconds, streaming is not affected, while in a game a second off might be too much already, however as such hardware failures happen rarely, i am running only one of them anyway.

    for firewall i am using shorewall, while for some special routing i also use unbound dns resolver (one can easily configure static results for any record) and haproxy with sni inspection for specific https routing for the rather specialized setup i have.

    my wifi is done by an openwrt but i only use it for having separate wifis bridged to their own vlans.

    thus this setup allows for multi-zone networks at home like a wifi for visitors with daily changing passwords and another fror chromecast or home automation, each with their own rules, hardware redundancy, special tweaking, everything that runs on gnu/linux is possible including pihole, wireguard, ddns solutions, traffic statistics, traffic shaping/QOS, traffic dumps or even SSL interception if you really want to import your own CA into your phone and see what data your phones apps (those that don’t use certificate pinning) are transfering when calling home, and much more.

    however regarding ddns it sometimes feels more safe and reliable to have a somehow reserved IP that would not change. some providers offer rather cheap tunnels for this purpose. i once had a free (ipv6) tunnel at hurricane electronic (besides another one for IPv4) but now i use VMs in data centers.

    i do not see any ready product to be that flexible. however to me the best ready router system seems to be openwrt, you are not bound to a hardware vendor, get security updates longer than with any commercial product, can 1:1 copy your config to a new device even if the hardware changes and has the possibility to add packages with special features to it.

    “openwrt” is IMHO the most flexible ready solution for longtime use. same as “pfsense” is also very worth looking at and has some similarities to openwrt while beeing different.
