Just finished Moving from Windows 7 Desktop to Windows 10 Laptop as the daily driver at work.
only thing i'm missing is my second screen and that's cause I'm missing the HDMI port on the Monitors we have here.
My Boss is going to buy what ever screen I pick out, with that said, what are your suggestions for a new monitor that is compatible with HDMI? (Which should be any recently made monitor, right? )

If going with a new monitor, I've always been partial to Dell 24" U2419H line. Nice color, crisp, clear.

If going new, I like 27" or larger.

If a single monitor, I agree 27 or larger would be the way to go. I have had 2 or more monitors for so long, it slips my brain that many will probably have one. I have found that 24" monitors hit a sweet spot with 2 or more.

I'm working with a 32", 24" and 20" right now, and wish for 3 40" monitors with how much I tend to have going on.

Dang, 3 40's would take up a lot of desk real estate. Wish I had that much desk room for those.

Virtual desktops works good for that. I set up 12 virtual desktops on my 40" monitor and switch between them with alt-ctrl+F1 up to F12 or the mouse.

The combination of large monitors and many virtual desktops causes you to work differently but more efficient. Basically you never maximize or minimize windows or use the taskbar to switch between application because there is no need to run anything in full screen. You just overlap the windows and use more virtual desktops when you need more space.

To keep my sanity I label the desktops if possible and always put certain things on certain desktops. For instance calendar, email and communication I always keep open on desktop 1. Music streaming and non-work related stuff on desktop 2. Then I have a couple of desktops where I remote into customers systems and run ssh and what not. One or two desktops where I manage our internal systems. If I need to research something I take an empty desktop and open up a browser or two there. So the desktops are kind of task related, not application related.

Are those VM's on a server or your workstation? Sounds like an interesting setup. I'm guessing they are linux desktops?

No, sorry. I actually use both VMs on a workstation and hosted, but this is not related to that. The "virtual desktops" are not virtual machines, just multiple desktops on the same computer.

Linux have had it for many years and you could do it on windows too for years with 3rd party software and lately with Windows 10 natively.

@scottalanmiller Check out Extended Events. It can log everything that happens.
Fastest way to learn more is probably to search youtube for sql server extended events.

Extended events are suppose to be the replacement for sql traces/profiling.

May Surprise: U.S. Adds 2.5 Million Jobs As Unemployment Dips To 13.3%

The U.S economy rebounded with surprising strength last month as businesses began to reopen from the coronavirus lockdown. U.S. employers added 2.5 million jobs in May, and the unemployment rate fell to 13.3%.

Stocks jumped sharply after Friday's jobs report was released. The Dow Jones Industrial Average ended the day up 829 points, more than 3%, and the S&P 500 climbed 2.6%.

Also, companies have to make sure they are compliant but it's not until something happens, like a data breach, that the authorities want to check what you have done to be compliant. If they find out that you did in fact not follow the GDPR you risk heavy fines.

This of course makes everyone and their grandma offer products and services and tout their GDRP compliant products.

I think lab exercises to learn something are pointless to a large degree.

I think it is better to make use of technology and by installing, setting up and using things, you will encounter problems that forces you to learn more about the subject and what you need in order to get the job done.

You will learn more that way and what you learn will have real world applications. But perhaps more importantly, you will be motivated to learn and get immediate gratification of having accomplished something meaningful when you succeed.

If you need to save what's on the disk you need to:

• insert the 1st drive on a linux computer (don't mount it) and make a dd image copy of the entire disk.
  Use options conv=noerror,sync so the drive keeps reading even after errors.
  Expect the cloning to take a long time if you have many bad blocks.
• do the same with the second disk.
• mount the cloned disks/images and run fsck on them or use recovery software
• recover or copy what is possible and copy the data to where you want it.

Don't do anything else with the failed disks other than clone them. That's data recovery 101.

@siringo said in What Are You Doing Right Now:

anyone looked at 2fa for W10? I'm looking for a way in which I can secure a W10 VM not domain joined and not using any bio security stuff, which would be hard to use on a vm anyway.

I think Duo and companies like OneLogin that offers authentication, SSO etc can do it.

@emad-r Two completely different solutions for different uses. Or are you thinking about it for privacy issues?

@Donahue said in Large or small Raid 5 with SSD:

So would this make a 4 drive raid 5 and an 8 drive raid 6 be similar in reliability?

You'd have to define reliability here. You are twice as likely to experience a drive failure on the 8-drive array. For data loss you are about the same - if you don't replace the failed drive.

In real life I feel it comes down to practical things. Like how big your budget is and how much storage you need. 4TB SSD is pretty standard so if you need 24 TB SSD then you need to use more drives. In almost no case would it be a good idea to use many small drives.

Many small drives will typically overrun the controller, too, making the performance gains that you expect to get, all lost.

Yes and as you mentioned above NVMe is where it's at when it comes to performance. SATA and SAS SSDs are for legacy applications - as Intel says.

@coliver said in What the??:

Wall mount or under mount computers are becoming a big trend. Not surprised one of the manufacturers are getting into it.

Makes sense if you think about that people are putting all that bling in their computers and then no one can see it.

If you wall mount it, well then it's a conversation piece.

However, how do I get grep to deliver the match (capturing group) and not the complete lines?

Don’t use grep? I have no idea what tool you actually want here.

Me neither. I just want to search a file and get a list of what matches.

grep should be able to do that natively now. We used to cat filename | grep

Grep returns the whole line where the string was found. He does not want that. He only wants to results of the regex.

OK, I think I have it.

-o, --only-matching
Print only the matched (non-empty) parts of a matching line, with each such part on a separate output line.

So grep pattern file -o should do the trick and it seems like it from my first test.

I couldn't find any of the settings, using the latest version of outlook..

What is the email server? Gmail? Outlook.com? O365? GSuite? ZoHo? You have to know this.

I don't have that information.. and I have no way of finding that out..

Well shit.

If you ever received an email from this person, you already have that information.

is that right?

can you explain what you mean, please ?

Take the email you received and look for "Show Original" or something similar in your mail client.

It will show all the headers and information that the mail servers have sent between them. There you can see what provider someone is using. Often also what mail client.

this?

spf=pass (google.com: domain

Don't trim it out.

I dont know what I'm looking for, Google wasn't much help but i'll figure it out

You're not just looking for one string. You need to look at the whole thing.

I suggest you copy the headers from the start until you reach the line starting with From:
Paste it into this page: https://mxtoolbox.com/EmailHeaders.aspx

It should tell you what servers are in use for sending and receiving.

@JaredBusch said in What flavor of linux to replace windows?:

No, I think you are just deluded, or refuse to see reality only because you are paid to push Windows solutions.

It is easily and simply possible to be completely OS agnostic in the modern era for any size of corporation.

Completely Agree

OK, so if it's so easy then how do @Donahue and the people he supports go about doing their jobs when Autocad is what they are using and AutoCAD doesn't run under linux? Find another equivalent app?

Well, you are aware that AutoCAD are industry leaders in their field? There are no equivalents and it's not just the software itself, it's the ecosystem of add-ons and small programs. It's also the fact that subcontractors and consultants have the same software and you need 100% compatibility when exchanging files. It's also the fact that AutoCAD is what people are trained to use and what you can get training and support on.

It's exactly the same with SolidWorks. And then if they are running manufacturing as well in the company they will have software that prepares the design files and convert them into instructions for the machines to manufacture. CAD/CAM and g-code files, management software for workflow and batch handling for machining centers and what not. It's all going to be software that runs under windows.

To some degree you can change software, say from SolidWorks to SolidEdge and retrain people maybe to save on licensing costs but like SolidEdge, any competing software on the same level will also be Windows.

So windows, windows, windows. Ain't no way around it. Not in 2018.

is that where most rentals have come from?

Most rentals existed long before 2008. The rental market has always been very large.

Oh, I'm sure it's been longer than 2008 - but when? When did mass rentals enter the scene?
I guess they really started in the beginning when companies built factory based towns. The company built the houses for their employees so they would have some place to live. etc.

A really long time ago (in the US). Most people used to be renters but after WW2 the majority have been homeowners.

Right now (2022) it's sits at around 65%.

Data is from U.S. Department of Housing and Urban Development.
https://www.huduser.gov/portal/Publications/pdf/HUD-7775.pdf

That's a lot of disks for such a small array.

I'd just put 6x12TB drives in RAID6 and put it on something that has at least 16x3.5" drive bays.
That way you have enough space to make a new array and transfer the data when it's time to upgrade the storage.

I'd very much prefer linux over windows for fileserver use and software raid over hardware. It's easier to have the data survive several generations of hardware as you can mount the old drives directly on a new server without problems. It becomes hardware and linux distro/version agnostic.

For our own use we like Supermicro hardware because they are modular as well. Supermicro sells their stuff as components as well as complete servers which makes it very flexible. Standard-sized server motherboards for instance means you can replace a motherboard without having to source exactly what you had. And you don't have to use their branded memory or branded disks.

@scottalanmiller said in Battery Backup with SSD raid:

SSD NV protection is to allow the SSD's cache to flush safely should power be lost. RAID NV / battery protection is to allow the RAID's cache to flush safely should power be lost. Each is important on its own, neither covers for the other one.

That's technically slightly incorrect.

The non-volatile cache memory on the raid controller is to be preserve the data that has not yet been written to the drives, until power is restored again.

On the SSD the capacitors hold enough charge so that the drive can write the remaining data in the cache memory to the actual flash memory after the power is gone. The cache is DRAM so it will loose it's contents after a few seconds.

The only time details like this matter is if you remove the battery from a raid card, your data might be lost.

I'm missing how that is different than what I said. What you said is correct, but I feel like you just reworded what I said, with the added detail that the RAID card flush is not until power is restored, which one hopes is obvious.

Sorry Scott, you're right. I was just thrown off by you said "SSD NV protection" and because you worded both thing the same. Obviously both things are to protect from data loss at power failures.

OIC, you are saying that the SSD is volatile, but has a battery in most cases? makes sense.

Almost, let me explain. Below is a picture of an Samsung enterprise SSD, SM863.

The SSD controller (yellow) is the brain. The flash memory (green cross) is non-volatile so it will not suffer data loss without power. There are also more flash memory on the backside.

The cache memory however is the blue ring and it will lose it's memory as soon as the power is removed. It's the same type as the memory in your computer, DRAM. That would cause immediate data loss and that is not good and that is why enterprise drives have a lot of capacitors (red circles).

The capacitors (red) act like small rechargeable batteries. When the drive loses it's external power these small capacitors will work as a reserve power for the entire drive. The controller (yellow) knows that it has lost external power so it will quickly write the data from the cache memory (blue) to the flash memory (green) before the reserve power from the capacitors (red) are empty. That way data loss is prevented. This will only take a couple of seconds at most.

@DustinB3403 said in Redundancy is building a bridge and an identical one immediately next to it:

Redundancy is just about improving the odds.

No, redundancy is not about improving the odds. Redundancy is about having a redundant item.

Let me rephrase it. The purpose of redundancy is to improve the odds.

But in your very example of evolution. If redundancy is such a great thing, certainly we would have 2 of literally organ.

Better odds if one dies, right? Not quite true as @scottalanmiller has mentioned.

I don't think redundancy is a great thing. I think you should do a risk assessment and then come up with a plan how to mitigate the risk. IT isn't different than anything else in this regard.

Regarding evolution we are probably more geared towards surviving external threats than we are towards surviving internal organ failures by old age and a sedentary lifestyle.

If you had 6x2TB in RAID10 that's only 6TB of actual storage. That's very modest storage requirements.
A simple RAID1 with two 12TB drives would double that. WD Ultrastar (former HGST Ultrastar) for instance.

I'm sure you can find other brands of hard drives regardless of what country you are in. You just need to find the right suppliers.

You handle storage expansion by adding a new array of disks.

Regardless of what drives you want even 5400 rpm drives will saturate a gigabit link. I have used WD Red and they were fine but I would look for drives with a 5 year warranty, not 3 years as WD Red have. The price difference is not that big.

Personally I wouldn't waste money on hardware raid but you need some kind of host adapter to access the drives. Software raid is very fast and RAID1 takes no cpu to speak of. With refurbished stuff you have to take what you can find though.

@PhlipElder said in DELL PowerEdge T410 - Memory Configuration Issues:

As a rule, the primary slot in each channel should be populated. So, 4 sticks per CPU.

Make sure Memory RAS settings are default and not stripe or mirror. That may be part of the problem.

Make sure the sticks are in the primary slot for each channel which is usually a different colour than the secondary and furthest from the CPU.

T410 is old 5500 series chipset which is triple channel, so I don't think you gain anything with 4 per CPU.
