Then why do you think manufacturers still list these failure rates (to be sure, it is marked as a limit, not an actual rate)? I'm not being sarcastic or facetious, but genuinely curious. Do you know for certain that it doesn't happen regularly? During a scrub, these are the kinds of errors that are quietly corrected (althouhg the scrub log would list them), as they are during normal operation (also logged).
My theory is that they are being cautious and/or perhaps don't have any high-confidence data that is more recent.

The Leopard 2 was designed in the 70s. So for battlefield vehicle designs, that is not necessarily outdated. Most fighter aircraft in use today were desgigned in the 70s: Su-27, MiG-29, sure, we think they're old, but the F-16, F-15, F/A-18 are roughly the same age.

Bit error rates have barely improved since then. So the probability of an error whenr reading a substantial fraction of a disk is now higher than it was in 2013.
But as others have pointed out. RAID is not, and never was, a substitute for a backup. Its purpose is to increase availability. And if that is critical to your enterprise, these things need to be taken into account, and it may turn out that raidz1 with 8 TB disks is fine for your application, or it may not. For private use, I wouldn't fret. but make frequent backups.
This article was not about total disk failure, but about the much more insidious undetected bit error.

Let's do the math:
The error-reate of modern hard disks is usually on the order of one undetectable error per 1E15 bits read, see for example the data sheet for the Seagate Exos 7E10. An 8 TB disk contains 6.4E13 (usable) bits, so when reading the whole disk you have roughly a 1 in 16 chance of an unrecoverable read error. Which is ok with zfs if all disks are working. The error-correction will detect and correct it. But during a resilver it can be a big problem.

Bloody bigots (if true). This is a desperate measure by Ukraine, from which the UAF actually refrained as long as the US supported them!
Now they don't and they don't.
So give them the means for a meaningful defense (and offensive) on their own land, and they won't have to resort to strategic bombing. (Or droning, or cruise-missiling, or whatever it's called.)
I know these are different parts of the government, but still.

Don’t think Mike Johnson wants to help Ukraine though. This is just him stalling for time.

It's a trap. If the House changes the bill, it has to pass through the Senate again, which is not guaranteed. This talk is intended to distract from the Discharge Petition that was initiated by a Democrat to approve the Senate's bill. The hardliner Republicans, first and foremost Mike Johnson, have made it crystal clear through their actions that they have no intentions of helping Ukraine. The Democrats built golden bridges by agreeing to border security measures which many of them find abhorrent, and by agreeing to combine it with help for Israel, which some Democrats also don't like at the moment. And still Johnson flatly refused to even consider it.
Speaker Johnson says the right things ("No one wants Vladimir Putin to prevail. I’m of the opinion that he wouldn’t stop at Ukraine … and go all through the way through Europe. There is a right and wrong there, a good versus evil in my view and Ukraine is the victim here"), but his actions speak louder with a very different message.

That's just drawing from a special Presidential fund. I forgot the name. It is only a couple of billions in total, and must last for a year and for everything the administration wants to support without Congressional approval.
And if the $60 billion main aid package is intended for a year, then $300 million is the equivalent of less than 2 day's worth.

They did. What the UK, the US and Russia(!) should do in case Ukraine is attacked, is to "seek immediate UN Security Council action" to provide assistance. Which the UK and the US did. Of course, that didn't achieve anything because of the veto powers of the permanent UN Security council member Russia.

The US and the UK were signatories to the Budapest Memorandum (all three memoranda, actually, there are similar ones with Belarus and Kazakhstan), but it was never intended as a mutual assistance treaty in the way the North Atlantic Treaty (the "NAT" part of "NATO") is. It was just an agreement to respect each other's territorial integrity and not to use weapons against each other. It literally says:
The Russian Federation, [...] reaffirm their obligation to refrain from the threat or use of force against the territorial integrity or political independence of Ukraine, and that none of their weapons will ever be used against Ukraine except in self-defense or otherwise in accordance with the Charter of the United Nations.
The cop-out clause, of course, was "except in self-defence", which is what Russia implicitly claims, when saying that its citizens in Donbas, and thus Russia itself, were under attack by Ukraine. Playing the victim has always been the preferred way to justify a war of aggression.
The part about giving up the nuclear weapons is implicit in the preamble which welcomes Ukraine to the non-proliferation treaty as a non-nuclear-weapon state.
The whole Memorandum is also really short, literally fits on a single page: https://en.wikisource.org/wiki/Ukraine._Memorandum_on_Security_Assurances

Ukraine never had effective control of the nuclear warheads, although they had physical control and probably could have made them unusable, but not fire them without some serious reverse-engineering and possibly rebuilding large parts.

Yes, and that was codified by all signatories of the Budapest Memorandum. Russia tries to argue that it hasn't violated the terms because it only uses weapons against another signatory state "in self-defense", which is an agreed exception. Everyone knows it's ludicrous, but apparently even Russia does not want to be perceived as violating agreements.

The very concept of "NATO expands" is misleading. NATO doesn't decide to expand. Countries that had previously been neutral apply for membership. Contrast that to how "Russkiy Mir" expands.

My main server is slowly failing, and I have set up a replacement machine, and thought, back in September 2023 or so, I'll swap it in as the production server when NetBSD 10 finally comes out. So it has been running almost every RC of NetBSD 10 and I still suffer an occasional server crash on the old machine (the new machine with NetBSD 10 RCx has been solid).
I still fully support the NetBSD release philosophy of "It will be released when it's ready", not being bound by any fixed time scheme. When release candidates contain known show-stopping errors, don't release it, plain and simple. I don't follow gnats (NetBSD bug tracking) closely, so I don't know what the issues are, but I'm sure they are important enough, even if it's just building or installing hiccups.
Other than that, for my workload, there is no impressive speedup or anything, ZFS is still the same version, and still very slow deleting files; otherwise it's hard to tell, because the hardware is somewhat different.

Tragic, if true, but you need to work on your texts and captions. HIMARS is rocket artillery, not an "anti-aircraft missile defense system": High-Mobility Artillery Rocket System. And what is the caption in the video? PC30? BCY?

Saying it hasn't been built in 30 years is a bit misleading. Although the base Il-76 airframes may be that old, the latest substantial avionics upgrade (designated A-50U) is less than 15 years old or so (first delivery in 2011), which isn't too bad for military and aircraft systems. A lot of the E-3 equipment is older. That is not to say it is more capable than the E-3, it probably isn't, but I'd say a fully functioning A-50U should not be underestimated. It's even got toilets! Then again, it is also not clear to me that any "U" models are currently airworthy.
As the title says, I am new to the Yamaha SY77, and I'm making a split voice with piano on the left and sax on the right, and I want the sustain footswitch only to affect the piano. (How) can this be done? It was trivial on the DX7 II-D with a Split-mode Performance, but I can't seem to find a setting on the SY77. Having programmed the DX7 (II) for a long time, and having read the SY77 manual, I had no big trouble finding my way around the 77, but this one baffles me. I would consider it pretty vanilla to be able to sustain piano chords with the left hand and and then play unsustained lead lines with the right. In most respects, real-time-controller-wise, the DX7 II seemed more flexible, even though undoubtedly the SY's synth engine is much more capable. (Also posted to reddit, since the community is still a lot larger, but I'm willing to give lemmy a chance ...)
I know that for decades now, hard disks don't really reveal their actual internal geometry (which is complicated anyway, since inner cylinders may have fewer sectors than outer cylinders, etc.), and present fictional geometries to satisfy legacy software, but I found it weird anyway. I have a ZFS raidz2 NAS which originally consisted of 8x2 TB SAS disks and is now in the process of being live-upgraded to 8x4 TB (change disks one by one, resilver, change, resilver, etc ...) I now have four of the disks replaced, and in NetBSD they all report different geometries. They all report the exact same number of total blocks, so it's not actually an issue, but still strange. >sd0 at scsibus0 target 0 lun 0: <SEAGATE, ST4000NM0023, GE11> disk fixed > > sd0: 3726 GB, 330809 cyl, 10 head, 2362 sec, 512 bytes/sect x 7814037168 sectors > > sd1 at scsibus0 target 1 lun 0: <SEAGATE, ST4000NM0023, GE11> disk fixed > > sd1: 3726 GB, 348145 cyl, 10 head, 2244 sec, 512 bytes/sect x 7814037168 sectors > > sd3 at scsibus0 target 3 lun 0: <IBM-B040, ST4000NM0023, BC5P> disk fixed > > sd3: 3726 GB, 342419 cyl, 10 head, 2282 sec, 512 bytes/sect x 7814037168 sectors > > sd7 at scsibus0 target 7 lun 0: <IBM-B040, ST4000NM0023, BC5P> disk fixed > > sd7: 3726 GB, 341874 cyl, 10 head, 2285 sec, 512 bytes/sect x 7814037168 sectors Two of them are IBM-branded (although they are in fact all [Seagate Constellation ES.3](https://www.seagate.com/www-content/product-content/constellation-fam/constellation-es/constellation-es-3/en-us/docs/constellation-es-3-data-sheet-ds1769-1-1210us.pdf)), so I might expect slight differences, but even those with the same branding and the same revision present different geometries. Anyway, probably just a curiosity, it will be interesting to find what the remaining four disks will show. I might add that the older 2 TB disks (Seagate Constalleation ES, IBM-branded) all show the exact same geometry: > sd2 at scsibus0 target 2 lun 0: <IBM-ESXS, ST32000444SS, BC2D> disk fixed > > sd2: 1863 GB, 249000 cyl, 8 head, 1961 sec, 512 bytes/sect x 3907029168 sectors > > sd4 at scsibus0 target 4 lun 0: <IBM-ESXS, ST32000444SS, BC2D> disk fixed > > sd4: 1863 GB, 249000 cyl, 8 head, 1961 sec, 512 bytes/sect x 3907029168 sectors > > sd5 at scsibus0 target 5 lun 0: <IBM-ESXS, ST32000444SS, BC2D> disk fixed > > sd5: 1863 GB, 249000 cyl, 8 head, 1961 sec, 512 bytes/sect x 3907029168 sectors > > sd6 at scsibus0 target 6 lun 0: <IBM-ESXS, ST32000444SS, BC2D> disk fixed > > sd6: 1863 GB, 249000 cyl, 8 head, 1961 sec, 512 bytes/sect x 3907029168 sectors
Hi, for a couple of days, now, shop.jeppesen.com (directly linked from jeppesen.com) has been down. The first days it showed a banner that it was "down due to technical issues", but since yesterday it just shows a banner saying "Jeppesen. A Boeing Company". Is anyone else here able to reach the shop? Is there any information about why, and how long this is going to last? I'm quite seriously confused and bewildered that the market leader for aeronautical charts could just "close shop" like that. The only thing I could imagine that would take so long is an attack where data could have been modified, including backups, requiring manual validation of **all** data.
I have two Dell T320 servers, which work great. But I'd like to have some more CPU power, so think about upgrading to the T420. It is almost the same, except that on the T420 main board, which seems to be otherwise the identical PCB, the second CPU socket is actually installed. (In the T320 it's just empty soldering points.) My question is: Is the air baffle the same, or do I need a new one if I swap out the main board? I am aware that I will need a second CPU heatsink. Thanks.

A four-part series of the interview with one of the greatest test pilots, D. P. Davies, conducted in 1992 for the Royal Aeronautical Society. Almost five hours of avgeek gold. (The other three parts should be listed at the bottom.) D. P. Davies is also the author of the seminal work about flying large airliners, "Handling the Big Jets". Although less well known, he is undoubtedly on the same level as Chuck Yeager and Bob Hoover. The level of expertise and adventure, combined with the British humour and understatement, makes this immensely enjoyable to listen to, despite the less-than-perfect audio quality.

We have several phones in our family, and all connect just fine, but not the 8T. Two of the working phones are OnePlus 6T on the same LineageOS version. Are there known problems specifically with the 8T? The phone charges fine when connected to the car, but the car does not recognize an android auto-capable phone. With the other phones, the AA icon appears instantly on the car screen, but nothing happens with the 8T. We upgraded to the latest lineageos build and tried different cables but no change. The car is a 2019 Peugeot 5008 II, if that matters.
Many news apps also have this issue: when I follow links for some time, basically surf the fediverse, it is awkward to return "home": you have to traverse your entire journey backwards.

According to [EU regulation 1178/2011](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:02011R1178-20221030), the only condition is that you have at least 12 takeoffs and landing and 12 hours (of which 6 as PIC) and one hour total flight time ("block time") of "refresher training" within the last 12 months before the end of the validity of the single-engine piston and/or touring motor glider class ratings. As far as I can tell, the one hour of refresher training doesn't even have to be one contiguous flight, but can be spread out over multiple flights. Only a proficiency check (i. e. checkride with official examiner, which is required if you don't have the prerequisite flight time) needs to be performed within the last 3 months before expiry.
I'm sure many have that problem right now (e. g. feddit.de is on 0.17.4), and I understand the developer's choice not to support old server versions anymore, so when I choose to stay with Jerboa 0.0.34 for the time being, I'd at least like to see when my instance upgrades to 0.18. I can see it at the bottom of the Communities list in the desktop browser, but haven't found it in the app, yet.

What's the general opinion on the BSDs? Are they just Unix-Like (like Linux), or are they really Unix? Some call them "heritage Unix", because, although they no longer contain a single line of AT&T code (and haven't for over 40 years), they were ultimately derived from the original Unix. This is a bit tongue-in-cheek, because I wonder, if you consider BSD to be "true Unix", what other "Unix-**like**" operating system besides Linux kernel-based systems there are. Or are "real" Unices also considered "unix-like"? As an aside, what about macOS, if you use the command line a lot?

I live relatively close to one of the hubs for A400M operations (Wunstorf), but currently have no flights planned in any of the restricted areas. I expect operations at Hannover EDDV to be affected, since Wunstorf is inside the Hannover control zone. Do any of you live inside the northeastern area which starts at ground level? Did you have to reschedule or reroute any flights?
I posted this on the flying community I started on feddit.de, but I guess having this international one makes sense. I will transform mine into a German-centered version. But here's my post about a recent little fly-in: Three times during summer the flying club at Hodenhagen EDVH invites the GA community to a Fly-In at the their local airfield. They have currywurst and fries and cold (non-alcoholic) drinks for a nice afternoon of talking and chilling. This time I took some friends, for one of them it was the first ever flight in a light aircraft, and we all enjoyed it. Tell us about your memorable flights!
