  • Storing Drivers Licence: Was answered elsewhere. Bottom line… Bitwarden seems like it can store other types of data. Note that I don’t use Bitwarden yet, but have experience with Enpass and 1Pass, both of which can store all sorts of data.

    Why separate storage if Bitwarden is E2EE? You are placing all your trust in a single organization - Bitwarden. If they get hacked, then it is possible for the hackers to poison their software to deliver master passwords (hacks of s/w repositories has happened). I prefer to separate encryption from storage so a hack in both is required to get my data. Note that I do the same for offsite backups to Glacier/S3. I use Arq to do the backup and encrypt the files, then send them to S3 for storage.

    The 2023 IBM Report on Cost of Data Breeches indicated that the average time for a company to discover a breech is about 200 days, and on average another 70 days to remediate. That keeps me up at night in my day job as security dude.




  • My approach to this is as follows:

    • the password manager is probably the most important and often used piece of software I own. We (wife and I share the vault) store everything important/private in there - bank details, hundreds of passwords, passport details, drivers licence etc. It is used many times a day by us both.
    • Loss of control of this data would be catastrophic, so I took its security very seriously.
    • No one company can be trusted with our data, because they all get hacked or make mistakes at some point.

    I’m the security dude for a cloud service provider in my day job, so my goal was to use Separation of Concerns to manage my passwords. I therefore split the software from the storage, choosing software from one company, and storage from a second company. That way, it requires a failure on both parties at the same time for me to lose control of all the data.

    I used to use OnePass for the software, storing the data in Dropbox. But then they removed that option, so I switched to Enpass. Data is stored in a vault on the local device and synced to a folder on Dropbox, which we both have access to from all our devices (Mac’s, iPads, iPhones). The vault is encrypted using our master password and Dropbox only sees an encrypted file. Enpass provides software that runs locally and doesn’t get a copy of my vault file.

    If Dropbox has another failure and the vault gets out, then that is not a problem as long as Enpass have properly encrypted it. If Enpass has a bug making the vaults crackable - again it’s not a problem as long as Dropbox doesn’t lose control of my vault file. I update Enpass, the vault gets fixed and life goes on.

    Enpass is very usable, but buggy. It crashes every night (requiring me to start it again and log in), and often loses connection to Safari and wont re-establish it. It got better with a previous update, but has got unreliable again. I’m about to look for another.

    Cheers.


  • I haven’t finished the article yet - but it was making some interesting points about people in the Donbas region wanting to join Russia, and that fighters there were locals, and not (as we have been told) itinerant Russians.

    That was different to what I have heard before, and he pointed to the referendum in 2022 that shows that 87% of Donbas support annexation to Russia. However… that referendum was taken after the invasion and so needs to be considered possibly suspect. Link

    Maybe a better source for a referendum was from before the initial 2014 annexation of Crimea and the accelerated fighting in Donbas from then. The only one I can find dates to 1991 - and it strongly shows a desire for independence, even in Donbas where it was over 80%. Link. Interestingly lowest support for independence was Crimea at 50-60%. Overall the country was 92% for with 84% turnout. That’s a pretty strong result, although a little old.


  • Be wary of RAID 5 or 6.

    They both have a « write hole » problem (or though much less so in RAID 6). Any power failure which causes an incomplete write can cause a complete RAID corruption - meaning all data is lost. Hardware RAID controllers usually have an onboard backup battery so they can store some information to complete operations should there be a sudden power failure. Software RAID does not have this, and you need to provide a UPS with automatic clean shutdown as the battery runs low using nut or some equivalent.

    Some people go as far as to say that RAID 5 should never be used.

    You also have very long recovery times when you replace a failed drive (days). Any other failure during this time means total data loss (of course RAID 6 gives you a second redundancy). Weekly Resyncs are very slow too (hours to days), and (unless you constrain your max throughput) will bring your system to its knees.

    zfs does not suffer from these problems, BTW.

    I run software RAID 5 via mdadm and have a UPS. I’ve replaced drives twice with no issues other than a slightly nervous long wait during recovery. I’m too cheap to buy the extra HDD for RAID 6, and may end up regretting it one day.


  • My $0.02c worth - I have run all sorts of servers at home over the years, and one of the main challenges around the hardware is managing heat.

    I’ve used mini-ITX mobos and tiny cases for builds. They look gorgeous, but at some point, when you stick enough drives in there (assuming you can) or make the CPU/GPU busy, you are going to have a heat problem, or a noise problem, or both.

    On my mythtv build I used M-itx and a gorgeous Lian Li small case. It was a beautiful add to my home theatre stack, but in the end I drilled a ton of small holes in the top and added a slow 140mm fan to control the heat without noise.

    The same goes for my file server - it was a slightly larger case with no GPU, but once I added my 6th HDD and had a ton of services running, heat became an issue and I was having to add extra fans, which could only be 80mm so they ran fast and noisy.

    My new build I’m going to go all the way with a Phanteks Enthoo Full Tower and a few 120mm fans. I’ve decided that looks don’t matter

    The other problem for me with these tiny builds is cable management. I’m complete shit at it, and small builds requires some skills. A big case gives you space to spread those cables out.

    Lastly, you can get ATX or EATX mobos with 6, 8 or more SATA connectors - room for growth! And there are very low power options available.

    I’ll soon have the appleTV + TV upstairs, laptop in the office, and the monster server downstairs with cat-6 + Gb fibre throughout.
