I'm in higher education, and we have about 4,000 - 5,000 workstations depending on the classifications of devices you do or don't count. In past years, with every new release of Windows, the same inevitable problem always happened: After holding off or completely skipping new Windows releases due to compatibility, accommodating the latest OS on some new devices for users (squeaky wheels getting grease), keeping old versions around just "because", upgrading devices through attrition, trying to predict if the next release would come soon enough to bother with one particular version or not (ahem, Win8!), and so on.... We would wind up with a very fragmented Windows install base. At one point, 50% XP, 0% Vista, 50% Win7. Then, 10% XP, 80% Win7, 10% Win8.1. Then, <1% XP/Win8.1, ~60% Win7, 40% Win10.
Microsoft introducing a servicing model for their OS with Windows 10 solved this problem pretty quickly. Not long into its lifespan, we had 75% Win10 and 25% Win7. We are currently at a point where 99% of our devices are running Windows 10, within [n-1] of the latest feature update. When Windows 11 was announced, I thought "great, this will be just another feature update and we'll carry on with this goodness."
But then, the Windows 11 system requirements came out. I'm not ticked off with UEFI/Secure Boot (this has commonplace for nearly a decade), but rather with the CPU requirements. Now I'll level with everyone and even Microsoft: I get it. I get that they require a particular generation of CPU to support new security features like HVCI and VBS. I get that in a business, devices from ~2016 are reaching the 5-year-old mark and that old devices can't be supported forever when you're trying to push hardware-based security features into the mainstream. I get that Windows 10 doesn't magically stop working or lose support once Windows 11 releases.
The problem is that anyone working in education (specifically higher ed, but probably almost any government outfit) knows that budgets can be tight, devices can be kept around for 7+ years, and that you often support several "have" and "have not" departments. A ton of perfectly capable (albeit older) hardware that is running Windows 10 at the moment simply won't get Windows 11. Departments
... keep reading on reddit ➡So I defragged my HDD till it was 0% fragmented. And after one restart voila it's 15% fragmented. Is it some windows issue or HDD issue? Also this was a freshly formatted drive. Also it's the 20H2 version of Windows. Does this update have some issues?
edit: this is 100% on mssql btw.
Hi everyone -
I'd like to see what the general consensus is nowadays about index fragmentation.
Our setup (like most nowadays) is all-flash on a SAN. We have a handful of servers ranging from 2tb to 30tb total each, spread across various datastores, etc. We're using a fairly high end storage system from Pure.
I've been here for a bit under a year and there wasn't any index maintenance to speak of for at least the last several years. I do update stats on all DBs every night (might be overkill but it doesn't cause any issues), but zero index rebuilds/reorgs. A lot of our tables have 99%+ logical fragmentation. Physical fragmentation I'm not really worried about because seek time on flash is basically zero.
So - what is everyone doing nowadays with indexes? Are you still rebuilding them? Does it really not matter as much anymore with instant lookup storage? Has anyone run hard numbers on queries before/after? I know we're nearing the limit of what our storage controller can handle I/O wise, but I'm not sure a huge project to get index maintenance done and scheduled (especially the initial one, which will be ROUGH) would help that.
I'd love to have a discussion on what everyone else is doing in 2021 and beyond. Please leave your thoughts!
Thank you
There was a time when there were comparatively few sites and games. Also, when stupid people's mental inertia prevented them from entering and making the place, be it a multiplayer game or an interest forum, less pleasant, but I don't think that's the main issue.
If there were only a few games, people could easily start arguments over why one is better than the other. Form clans. There still are argument between popular games why one is better than the other, but 1) they have to agree that they're not a bad ripoff at least, which makes the controversy less heated, and 2) they're still not as popular as they could be. If someone says what they enjoy, others won't even know, so many titles out there. Argument can't rise between online boundaries anymore.
And the ultimate proof to that, I saw when football between countries got popular again recently, and the arguments even used vengeance tactics that are as old as time. People cling to boundaries that make sense, like those of a country, and that seals it. My dream of riding on the conflict of gaming world, that I long kept hidden even from my own consciousness, is dead.
I've been killed more than once by SPP where I only get hit once or twice in the arm and the death screen reports 8 or more collateral fragmentation hits. Has this happened to anyone else?
I've had a lot of joy with Burst Cannons, but AFP seem to get a lot of praise. Which tends to be better on a large Crisis Suit unit?
Hi, i am a poly-fragmented system...recently I've been observing how many systems with fewer alters work and I've just found my experiences to be very different. Other poly-fragmented system that switch more often and rapidly isn't an experience we commonly observed as well.
For us, our system has a more unique way of categorising trauma...it doesn't operate with the context of time, but well with context.... For example, most alters do not hold a single event of trauma, but rather they contain specific memories and traumas relating to a singular core topic. All instances of sexual shame go into an alter while all instances of sexual grooming go into another. Most of us do not necessarily have the memories pertaining to where the feelings and concepts stem from....just an overwhelming sense of sexual shame for example...or religious guilt...
We all do have different characteristics and accents and all that makes an alter and individual and not a fragment. But the concept of splitting an event into so many separate and niche areas does feel extremely fragmented. So I'm just very confused about how to see our system as a whole. Albeit our system has 2 Hosts Me and my co-host Dia, we are in the front most of the time and are not able to acccess the inner world actively. Tbh I don't think we switch with the others that often? If so there's no way I really remember, we always do find notes and stuff around though which means I guess we do switch but I don't think it's as much as compared to other poly fragmented DID systems.
Oh, btw I should mention that we have been diagnosed officially and we have come to terms with being a system. It's more on exploring and noticing how our system has an intense sorting system, that breaks down many aspects of trauma into components like, emotions, thoughts, idealisms, memories and even physical dysphoria. These components either go into alters that have trauma pertaining to the specific component or it gets too much to bear and a new alter splits forth.
We have been trying EMDR that is supposed to help with accessing memories. But we have been had a lot of trouble with it lately. Simply because all the components of the memory/ the trauma is not in one place but rather spread out among many alters and in very specific ways. The trauma is broken down and so heavily compartmentalized that it's really hard to get to figuring out what happened and what has been going on.
Does anyone have any similar experie
... keep reading on reddit ➡So, I was just informed that apparently it takes several minutes to delete even a single device from SCCM, and that it's been this way at least since the beginning of the year. Now, I'm not seeing anything in SCCM indicating a problem, but I have confirmed that deleting and re-registering devices takes maybe 10+ minutes, even when I'm RDP'd directly into the server. Since I'm not seeing any errors or warnings in SCCM, I started digging into the SQL end of things.
In the SQL server I'm seeing regularly maxed out CPU usage, and nearly maxed RAM usage, which I'm sure isn't helping things. However, I'm guessing these two things are just symptoms of the actual cause, DB fragmentation. I'm seeing EXTREMELY high fragmentation in the SUSDB and CM DBs (the ReportServer and other DBs are all fine), in the high 90% range.
So, I want to run some cleanup on both of the databases, but I've never had to do this before. I found a couple different guides online which at least appear trustworthy, but since I'm not a SQL admin, I'm not sure if they're still valid (they're only a couple years old, so they should be fine) or if they're ACTUALLY trustworthy.
Anyone have some advice here? The two guides I found are below. If anyone knows of other fragmentation methods or guides that they've used and trust, please feel free to give them a mention.

Hello everyone,
I am currently trying to implement the TCP/IP stack in Verilog, and I have been following the RFCs. I am unsure how I should move forward with the IPv4 fragmentation and reassembly implementation. Therefore, I wanted to know about resources that I can follow to better understand the implementation of those two topics in technical detail.
Thanks.
Hello all!
I have been hesitating to write this post for sometime, but I have promised myself that with a positive outcome and god's will to have everything work out, I would write it as a reminder of hope to fellow men and women in this subreddit.
I apologize for the long post in advance, but I hope you take this as me getting something off my chest.
My wife and I have been married for 4 years, with the exception of the first year due to her being focused on her Masters and I'm starting a prominent career, we have been very eager to have a baby! We are young, were healthy to that point to a large extent, even she was on her to the Olympics a couple of years before our marriage.
The story begins with my wife finishing her master's panel and we decided that we want to start trying having a baby. We tried and then surprisingly, the first month of doing so, she was pregnant! We were excited, happy, and relieved, we thought that the scary part was over.... but it wasn't. We went in to confirm the pregnancy through a blood hcg test and we got a positive, then we started going to a family's OBG and he recommended to do a quantitative hcg test twice with 48 hours in between and come back with the numbers. The first was 104 and the second came back 145. This number was worrying, as we have read during the 48 hours that the number should ideally double, more or less. We went through a very scary day or two, until bleeding started.... Confused and scared we lived through one of my worst memories to date. We went after a week for a 3rd test, and the number more than doubled! We were back to excitement as that was an indication to things being normal. Little did we know that the bleeding would start again.... It was inevitable at this point, and going in for an emergency ultrasound, we were given the news that she should be around 6 weeks pregnant, while the baby sac is empty and would've been normal only if she was around 4 weeks pregnant. Reality started to sink in and she was scheduled for a dnc the following day. We lived through depression largely for a couple of months, my wife even travelled to Australia to visit her family in order to try and get some of that distance from the painful incident. We simply were introduced to the harsh reality of miscarriages that for some reason, no one really talks about.
Fast forward 3 months, we are just back from Dubai and she was pregnant again! (We never stopped trying in this whole story and I have to give very hig

Is the current fragmentation of wallet standards and by that the security to access nano coins if something happens to the current wallets.
This concern came to my attention through these recent threads: https://www.reddit.com/r/nanocurrency/comments/mo4ga7/nano_mnemonic_vs_bip39/ and https://www.reddit.com/r/nanocurrency/comments/mne3sc/any_multi_coin_wallet_that_supports_nano/
Everybody should read the above threads, look into https://nanowallets.guide/ (Should be updated for even easier comparison of wallets and standards) and by that make a decision on what standard to use, to secure access to ones Nano Coins.
The following two (now 5) tools should be remembered by everybody who owns Nano, maybe even downloaded so access to funds is secure in the future.
- https://tools.nanos.cc/?tool=seed 2. https://iancoleman.io/bip39/ 3. https://tools.nanos.cc/?tool=sweep 4. https://github.com/roosmaa/nano-bip39-demo and 5. nault.cc
This is very important information to me, and I think for others as well, especially people new to Nano or crypto in general. So important that this or similar information should be stickied.
My take on what should be done:
Nault is the only wallet I know that accepts the import of Nano Seed, Nano Mnemonic, Bip39 Seed, Bip39 Mnemonic. More wallets should do this.
More wallets should be able to export Nano Seed, Nano Mnemonic, Bip39 Seed, Bip39 Mnemonic.
Most important here is as I see it to export and import Nano Mnemonic and Bip39 Mnemonic.
How? I don't know, and I don't think I can do this, but maybe the community can do this together?
Edit: More tools added.

I feel like this is mostly good news, however the painted "carrot" stick is still being dangled. After analyzing this article, I found an immense amount of contradictions. How is it that 75% with ONE dose is considered enough to re open the whole country? Does this mean that there really isn't as much uptake as the "data" is presenting? The article blantatly says that the vaccines are not enough to protect people. Are they flat out now admitting that this was a fear mongering political plan? Or are they trying to instill more fear to discourage people from travelling?
Anyways, I am done with this. We have rights to move around our home country as Canadians.
If there is anything I have learned, it's incredibly important to keep things simple, be patient, and not make decisions in the heat of emotions. I am staying strong and standing up for those to make their own choices based on their own health and livelyhood.
I hope to hear any thoughts
I have friends who have DID and OSDD and they’ve all thought that I have some form of OSDD. I go very back and forth on it and whenever I think I have OSDD, at least in the past I’d always end up freaking out and berating myself for ever thinking I did because I didn’t want to seem like those people who don’t do any research on DID/OSDD and then claim they have it. (I don’t mean any hate to people who genuinely believe they have it and don’t have the resources whether emotional, financial, etc to get therapy and a diagnosis)
I act like I have OSDD sometimes and I have terrible terrible memory that’s gotten worse lately, but it just seems different. Something I can’t shake though is this. No matter what I think I can’t explain it. There have been many many times, I think even times when I was a kid where i’d suddenly just be in this very very adult like “mode,” when I usually feel as if I’m a child living in an adults body.
Even when I sometimes feel normal, this “mode” is just so much more adult. I feel like a different person, I view her (the mode I feel) like a different person. I call her by my name, but I think that’s because I used to go by a different name for a long time and so it was easier to use my real name for her. Every time I start talking about this too I dissociate so bad I pause and forget what I’m doing. I don’t usually experience dissociation like this, it’s just different.
When I’m her my internal monologue’s voice is different too. You know how you imagine how you look internally? Or like if you’re daydreaming you’d see how you look? I think like that and daydream a lot and when I’m her the way I look is different. If had other parts that aren’t as distinct that people have noticed, but none of them are nearly as distinct as her.
Whenever I feel like her I’ll feel like I’m being taken care of, like she’s taking care of me. I’ll sometimes internally talk to myself as if myself is a little sister I’m taking care of and it does feel like that “mode” is a big sister type of person. My voice gets much deeper too and I’m way more confident too and don’t feel afraid to ask for things as much when usually I can barely go to the store by myself.
My face even feels different, the skin around my eyes. I don’t know why it would though. She has been gone for a while and it makes me sad. I feel alone without her and talking about her makes me feel like she’s back a little bit, but it’s not the same. Her presence feels so much smaller and li

There is another subreddit r/PanicPlaydate. Could the admins join the two groups please?
Is there any useful software for in silico fragmentation? I use a QTOF for nontargeted analysis (running under Sciex OS) and find the embedded in silico fragmentation tool almost useless. There is for instance almost no difference in theoretical fragmentation between a substituted melamine and a compound having a tetrazole and a piperazine ring. Any useful suggestions?
Hello all,
Recently I've been having issues with my WD Elements Portable 5TB hard drive, formatted to NTFS. Initially it seemed only Plex was running slower and slower as I expanded my library, but it seems the HDD was at fault.
It's been running for almost 6 months now, with 0 defragmentation or error checks. Write performance is higher than read performance. I ran a benchmark on it, write and read performance drops to 10% of initial values after a few iterations - it's terrible. chkdsk is still running, but it seems there are a lot of bad clusters.
How do you maintain your HDD?
- do you have a HDD bay / NAS which does this automatically?
- is another file system better suited than NTFS? Shield supports exFAT and HFS+ as well.
- do you periodically defragment & error check the HDD on a separate computer?
- is there an app / script for the Shield which can do defragmentation and error checking for you? (obviously not NTFS defragmentation)
