@Jason We only have a handful of different things from there but haven't run into anything like that yet. I've seen a couple of their desk chairs that didn't seem like great values, and I can't speak at all about the several hundred dollar stuff.

But my experience comparing the flimsy particle board and cardboard you can get for the price, they've seemed like a lot better option for a few things.

If you don't wander across something perfect, an Ikea tabletop with separate legs would probably be bigger and more solid than much else you could find for the price. They won't ship everything they sell, but usually will have an option or two that doesn't add a $349 truck delivery when you add it to the cart. Some of the legs they sell are adjustable height too.

sounds glitchy, I've never seen it behave like that either.

I can't speak to the 6s series with the force touch, but spent a short time around a repair shop and they didn't carry home buttons for the 5s/6/6+ with Touch ID because the buttons were paired to the boards like @Nic said. Tearing a home button flex cable would have meant buying a replacement phone. Not sure if the newest models have more limits than that.

Screen repairs mostly didn't have any other effect like this, but they would warn people of a chance that the Touch ID might not work after a screen repair. "We've personally read about it happening but never seen one," and continued with that line even after I saw one had happened there myself.

@travisdh1's thread title made me think of these photos I saw today: http://www.theguardian.com/us-news/2016/feb/04/san-francisco-then-and-now-super-bowl-50

They put together shots from SF from the last 160+ years, then went and took new pictures from the same locations.

@Minion-Queen I've gathered many of you have worked together or gotten to know each other through your careers, and I've gotten kind of curious what are your goals for ML and GroveSocial?

Do you picture keeping ML as personal, friendly, helpful and knowledgeable on a lot bigger scale? Does it kind of happen to sustain itself as part of NTG, and benefit anyone here at the same time?

If a lot of these seem to have more value from the material studied than from the cert itself, are there any others that stand out as covering important ground?

I've seen a consensus here that Network+ and maybe Security+ offer some value as a base, and afterward certifications quickly start to depend on the direction you want to be taking.

It'd be cool to hear opinions about others that can be valuable down different tracks.

Off the top of my head I'm interested in thoughts about the LPIC and Red Hat, Cisco, different security certifications, and maybe some less technical ones, for example project management.

Opinions about any you've found to be a waste of time would be interesting too.

So would any correlation you perceive with any of them, through hiring or people you've worked with.

@LAH3385 That was the short version

Per-processor OS licensing has been based on the total number of physical chips in use, more than what is in each physical chip.

But the operating system sees the total number of logical processors that are available. This number is based on the number of physical chips, but also on the number of CPUs in each chip, the number of cores in each CPU, and the number of thread handlers in each core.

The board, socket, physical chip, die, CPU, and cores have separate definitions that can sometimes be confused by marketing.

Multithreading can offer benefits by moving specific responsibilities from the OS to the processor, but only for specific uses that can take advantage of that. In the past, operating systems generally weren't designed to take full advantage of multithreading.

I'm not sure that shorter version will leave you any better off, though.. I imagine it'd be hard to continue learning a language through reading about IT, too. If you can work through the definitions and examples @scottalanmiller laid out, each section follows straight from the explanation before it.

I've heard you mention that as you started out, you were on top of a sense of the best books and resources for all these different topics that evolved as new editions and entries came out, and that this eventually became harder to maintain.

I wasn't sure whether you were referring to a lot of learning starting to move toward Googling and boards, or any change in what's available in books, or maybe if your experience just got to a point where that wasn't as necessary.

A board thread might not be the best format for organizing this, but I'd be really interested in some comprehensive recommended reading too, maybe split into areas. As much as the lab is better for learning in a lot of ways, sometimes I wonder if I miss a lot at times that way too.

There are a lot of great threads here that go back and break different things down really well. I'm just really bent on making sure I have the basics of basics down, so everything can continue to build from there with hopefully fewer rude lessons down the road. Recently I've been soaking up parts of different things from languages to admin stuff to networking fundamentals to beginner security.

I believe the work will pay off, and if there are some consensus books that have been valuable and pretty bulletproof, I'd like to chew on a couple to start with. I think it'd be good to start to feel like I'm getting a lot deeper within a thing or two compared to more superficial across more different areas.

Thank you, and everyone here too, for all your contributions. I believe I was searching a little while back for reading on RAID and file systems, when I first came across something you'd written.

I appreciate this type of stuff @scottalanmiller, and I've been continuing to gradually work my way through some of your archives on StorageCraft, Datamation and your SMB IT Journal along with keeping an eye out here when I can.

@Joel

Everyone's pretty much covered that your IP ranges won't really have any effect for security or anything. But I guess to try to answer a little more of what you're asking, I'd say subnetting is really for situations where you'd walk in to set up a network given guidelines like "We need 20 subnets, with up to 600 addresses on each subnet", or "We need 5 subnets, with however many addresses on each".

Subnetting's pretty much just the math that lets you take those guidelines and make sure you'll have them covered. Like others mentioned, it's based on binary.

For example, it ends up on a basic level not really mattering whether you need 600 addresses or 700 per subnet, because everything is based on the pattern 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024...

Once you need more than 512 addresses per subnet (actually 510 for other reasons), your subnetting results won't change up until the point where you'd need over 1024 (really 1022).

Solving to make sure you have the number of subnets you need is also based on using that same number pattern to split up the addresses you have to work with.

Other sites can explain binary counting a lot better than I could try to, but 8 bits of data can work together to represent values from 0 through 255 like we see in those network addresses (256 values total since we started at 0).

Any address like 10.2.208.144 doesn't tell us much by itself about what's going on around it, but if you know what the mask is from /8 to /31 or so, it'll be enough to figure out the usable range of how many other addresses might be in its network, what the subnet's broadcast address is, where the next subnet starts, and how many other subnets you have to work with.

I watched Jeremy Cioara's CBT Nuggets and thought he was great. He talked about how much trouble people can have with subnetting and its math, but to me he taught it really clearly. He joked being facetious once about starting to use 10.x.x.x ranges instead of 192 ranges because they're cooler and "more professional", but really there's not any hidden benefit before your guidelines require you to have more of a plan for your subnets, for reasons others have mentioned.

In the past, the range of addresses was split up into different ranges or classes, but they don't really come into play any more. About right after I learned about the classes, I learned they come up more on certification tests than in other environments.

@scottalanmiller, curious if 10 has been more solid for you lately? It seems like within the last few weeks had been seeing reports of multiple restarts daily.

@Dashrender said:

In 10 you can't do it through a browser? Why not? If you installed Chrome or FF on Windows 10, it wouldn't run? WTF? Are you saying the website knew it was Windows 10 and refused to run outside of their what appears to be a crappy app?

You should be able to solve that by changing the browser string in Chrome or FF (though if the site is doing IP stack scanning to check Windows version, you'll need an IP stack proxy program (that I only just learned about last week - thanks Steve Gibson) that will obfuscate your IP stack.

Yes, the page ends up on a message forcing you to the app.

Interesting idea for a workaround.

@JaredBusch said:

Because he only tried Edge obviously. Edge has no plugin infrastructure yet. This is a huge failing on MS' part.

IE and Edge. I'll leave the tone alone.

@Dashrender said:

You mentioned your store experience - what was the issue.

I've got to run for now but can hit on this quick.

Fox Sports has an app that works well on Android for streaming. They offer it on Windows too, through a browser on 7. I was trying to run it to a TV with HDMI, but after logging in, it worked until the point where you start the stream, and then sat there indefinitely. Tried in 3 different browsers ranging from add-ons to completely stock. So I broke out the old computer, and in 10 you can't do it through a browser and need to install an app.

That 10 minutes was pretty goofy. One or two big half-screen dialog boxes with no text and an OK button, just from opening and starting to navigate.

I'm trying to think exactly what the weirdest part was regarding. After I made it to the app page, it had a couple preinstall checkboxes, maybe they were for automatic updates, or location services. And I remember if I picked one option, the page would just refuse to load, and show me an empty apparent error. After trying the other option, it loaded normally now that it had forced me to that opposite option.

Then there was one more similar round of that, where the option I chose just loaded to a blank page, until trying the option I didn't want let it start to work like it was supposed to. I couldn't have made it up. It would have been a stretch for the normal range of Android glitches and seemed senseless on a desktop.

A lot of this is just the app developers, and when I opened the app it failed at the same point it had on Windows 7. But the store was weird before I made it that far too.

@scottalanmiller said:

I don't see any inconsistencies. Staying updated is important and a best practice but nothing in a panacea.

I'd describe the first one as, they're hounding people, talking about improvements. Follow the process they offer you, and end up running into these issues.

Now even throw that out, because it's our job to keep learning and find independently of MS that we can use a workaround that's more of a hassle than we were promised. But how do you like this so far? If you consider if it weren't MS who you've been working with for decades, would you see it any differently? (Also curious for reference, did a fresh reinstall after your upgrade resolve the issues you've been having?)

The second one follows, and is there a strong base here to have faith in what we're being offered?

I'm thinking of the other thread discussing people following vendor advice. Here, we can't even really "trust, but verify".

If there aren't a lot of good alternatives to trusting, that still doesn't seem to make trusting so black and white.

@Dashrender These are more good points. I'll continue to play devil's advocate a little here but I know splitting from best practices on this wouldn't be a sustainable thing either.

A lot of people are barely coming to accept that regular updates are best for them, and would rather continue to work around the annoying notifications because the risk of something changing in a bad way seems higher than the chance of anything improving + considering unknown security-type stuff. When something like last summer's iOS update opens the possibility they can end up with a fairly disabled phone until another fix comes out, it's hard to say they're not justified.

I did the upgrade on an older laptop out of curiosity, and after moving files off didn't ask the upgrade to try to keep any data or any other programs along. The Windows store is where I saw most of my issues. Out of curiosity I think at some point I'll give it another fresh shot from scratch.

Whether most people would have any interest in putting that much time into it or giving it those chances is irrelevant though, because it's our job to handle all that and present them with usable systems.

I really don't mean to take this down a paranoid/security/move to a cave track and you make good points there too. Before I continue more months of studying I always feel like I'm mostly talking out of my ass about security anyway, or at least missing complexities. So I'll try not to hit too much more on this part here.

They are admitting/telling some things, but some updates are more opaque too.

The Samsung example is obscene for sure. If our focus is on trusting and staying patched, the baseline for that stuff can continue to shift even a lot further. Bigger companies have more to lose and that's a fair point too, and they also have a lot of people dependent on their products who might not like the idea of some of this stuff but only have inconvenient alternatives.
