Holy crap, just got a demo of the new Group Policy analytics in Intune that rolled out for everyone this weekend, from the guy that’s been working on it with MS for the last 3 years.

Export all your GPOs, upload them into the tool, and it will tell you what CSPs you need to apply, which ones can’t, etc. Soooo much better than an mmat report that may not even capture everything. Where the hell was this a year ago when we were rolling out intune for workstation management?

Super glad I have been putting this off for the past couple of weeks.

The last version of my resume is dated 2011... A buddy referred me to a possibly job opportunity and for the first time in 16 years I'm thinking about changing companies on my own volition (been through 3 acquisitions so far). I should have kept a running list of accomplishments over the years, cause I barely remember last month much less 6 months or 2 years ago.

BLack Summer was the Best Summer

In an email thread, I had an engineer say this.

quote:

From an OS level perspective, the old machine was built on an out of the box Linux distribution. The new host was fully optimize at the Kernel level for high loads an network throughput. Nonetheless, the bulk of the performance solely relies on the applications ability to use those resources. If anyone wants to get on a teams share, I can show what those optimizations consist of, as I still have that host defined in Foreman.

My bullshit meter is going off like crazy. Any linux nerd out there able to tell me what kind of bullshit we are being fed here?

Unless you are doing some kind of extreme optimization for some specific process or are dealing with some custom hardware that you need to build your own support for (like embedded devices), this just sounds like someone is making a headache for someone else in the future because they want to.

If they're just turning poo poo off and recompiling a kernel, it's probably dumb and pointless since in any decent modern distribution those components are all modular anyways. Standard poo poo where possible always to make maintenance easier.

We do that kind of customization but our applications can saturate 4x 40Gbs lines with live ticker data. I looked through your posts and you mentioned around 5Mbs correct? From what you posted it sounds like someone is questioning why throughput is so low. It's more often than not the application being inefficient with the resources available unless you're running everything on a Pi or something.

some basic network optimization of dubious utility?
code:
net.ipv4.tcp_window_scaling = 0
this could be bad if this server is supposed to be accepting connections from clients with higher latency connections, ie anything over your average mid/high distance WAN link or anything coming from the internet. throughput is gonna suck if window scaling is off
code:
net.ipv4.tcp_tw_recycle = 1
this shouldn't be enabled on a server and can wreak havoc with load balancers and remote users behind NATs

i'm guessing someone is trying to fix an issue with an application that's not handling connections very well and are seeing tons of connections sticking in TIME_WAIT? instead of loving with this the app needs to be made to clean up after itself and close out connections.

if it's not that then idk why you'd do those tweaks.

If I were ever in charge of a support ticketing system I would let people submit the first request via email (reluctantly - a form can capture a lot more useful information), but everything after that point would have to be entered into the ticket system. Use a unique link if you want so people don't have to create yet another account, but I've got no interest in trying to parse emails once a chain builds up.

Yeah the kernel and vm settings are irrelevant.

Base mss is a little fucky but other than what’s been mentioned the rest is just ‘make the buffer bigger’ generic tuning.

It blew my mind when I found out everyone in the US had to file their taxes every year like they're running a business or something. Over here in the UK you just get an amount deducted from your paycheque each month and you don't have to do anything. It's mostly the responsibility of the finance department of the organisation you work for.

The US system just seems the worst of all worlds, no wonder people over there get so mad about taxes. Like how labels on products don't actually reflect the amount you pay at the till since they don't include state sales taxes, so you have to manually add that on in your head.

They do deduct it from your check. Most people can file a very simple tax form, your company gives you a W-2 and you copy some numbers over from that to the official tax form. Many employers have the information online so you can just enter your name and the employer tax ID.

Where taxes get complicated is if you are deducting expenses, dependents (such as children) interest, have investment returns or lottery winnings, other income like side jobs...Not that I would argue that the tax code isn't over-complicated. You can pay an accountant $300 to find you a bunch of loopholes and save you money on your taxes.

This is the EZ form:

Nobody gets mad about that. You'd have to label things differently for every municipality since you can have state, county, and city sales taxes.

...so? The shop knows what things cost so they can charge you the after-tax amount at the till, after all.

My "no wonder people get mad about taxes" comment was because the labelling system draws attention to the taxes by not including it on the label. In the UK a product might cost £4.50, so it's labelled as £4.50 and you pay £4.50. In Minnesota, a product might be labelled as $4.50, but when you get to the till you have to pay $4.50 plus sales tax, so it's actually $4.81, which draws attention to the taxes. If the same product was labelled as costing $3.00 but you then had to pay a 50% transportation charge on top of that, people would get mad about transportation charges. As it is that's just baked into the labelled price, so it's invisible to the customer, so they don't think about it nearly as much as the tax charge.

They only people I've seen make a big deal about that are, uh, 'lower-income' people who think they're getting ripped off and apparently made it their whole lives without paying sales tax.

In the restaurants in the seedier parts of town they often put the out the door prices on food. So on the wall you have odd prices like $4.81 for a sandwich or $1.67 for a drink.

And how much did your take-home increase after taking into account all the insurance bullshit you need to even come close to what's provided over the regular income tax in the UK?

I did the math on doing the same a few years ago, but moving from Norway, and the conclusion was easily "gently caress that poo poo, it ain't worth it".

Believe it or not some employers fully pay health insurance premiums. So the most you'd spend out of pocket is $0-2500 for a deductible.

And that span in deductible is ... Here it's $250.
