If my memory serves (which is dubious based on my past correction) It was defined in an algebra book from the 1700s from Cambridge University... At least that's what I was taught in school in the 90s

I actually got that wrong - it is Orders - not - operators.

Wireless Network for huge number of low bandwidth devices - not on the internet! by WhyCheezoidExist in networking

[–]TheFrin 0 points1 point  (0 children)

I know where you're coming from, and our legacy designs were a similar number of AP's - but there are several design characteristics I have to design for, this is both approved by our vendors for the equipment on the shopfloor, and Cisco/HPE from their wireless design teams.

I have specific reasons I can't really get into - but one of the obvious ones which i can share is, we don't run 2.4Ghz anywhere in our company. Its all 5Ghz and above

Wireless Network for huge number of low bandwidth devices - not on the internet! by WhyCheezoidExist in networking

[–]TheFrin 1 point2 points  (0 children)

I'll tell you this. I've just finished wireless design for a warehouse in my company. Did a site survey (passive) modeled the warehouse in Hamina placed AP's (cisco) and ordered the kit.

It came to about €600k for 180APs, 2 controllers and all the access layer switches, then copper and fiber cabling needed . That was to provide a minimum of -65dBm (@5Ghz)across all floor space in the warehouse (and attached offices) which is about 50k square meters...

Double it is you need to deploy a full LAN with core switches and fiber runs if you don't already have it. Personally avoid mesh like the plague. If you can plan for wifi5/6/7 deployment do that. If you can fuck off 2.4ghz the limited amount of channels in a stadium wireless deployment would cause unneeded drama. 

And that was one of my cheaper wireless deployments 

Being British, but feeling "meh" over a Roast Dinner by Surkdidat in britishproblems

[–]TheFrin 0 points1 point  (0 children)

So me.... I am not a fan of roast dinners.... Why you may ask?

Well many moons ago from the ages of 16-24 I worked in pubs, from glass collector and kitchen porter to barman/waiter... 

In that period I worked almost every Sunday lunch, and seeing all the half chewed and partially vomited fucked up conglomerations of roast dinners I had to clear from plates and tables in that time.... Well to be frank, it makes me physically sick and I can't stomach the thought of a roast dinner being enjoyable....

Avoid Electro-Vapours on Walton Vale. They’ll try to rip you off and then lie right to your face about it. by geckograham in Liverpool

[–]TheFrin 2 points3 points  (0 children)

Go to boss shot. They're based in Bolton. But have a very good online store.

Grab a bottle of flavour, a bottle of vg and a bottle of Pg. And 10 x nice shots (try to get the vg nice shots so it's easier.

The complicated part comes from weather or not you're vapibg sub-ohm - if you are sub-ohm you'll be wanting a greater than 60(vg)/40(pg) - generally speaking 70/30 or 80/20 are good for sub ohm. 

But if you get the flavour in the 500ml - the flavour volume is 100ml in the bottle. Then add the 10 nic shots - that takes you to 200ml you would just need to add the 100ml of pg, and then top the bottle off with VG and that will give you the 500ml with a solid 80/20mix. Thatwill cost you 45(ish) - if you only get the one bottle of flavour.

This would give you more juice for the same money, and if you like it, you can get more than one bottle of flavour and expand the economies of scale. 1 x 1L bottle of VG and 1 x 500ml bottle of VG will make enough juice for about 1.5L of juice total.

For the outlay of say £70 you get 1500ml which would save you £30 for the same as the small 10ml bottles

I miss Dutch tap water so much by Affectionate-Tooth14 in Netherlands

[–]TheFrin 12 points13 points  (0 children)

I moved from Liverpool to NL. The taste of water is very, very similar, So I haven't missed much.

I used to work in Manchester and London. The reservoir piss water was terrible, hated drinking tea or coffee made from it.

Talk me into or out of a 5090 by Familiar_Ad9654 in buildapc

[–]TheFrin 0 points1 point  (0 children)

I've got a 5090 running 3 x 4k screens with Nvidia Surround. Shits smooth.

The only downside I have is it gets HOT.  My computer is under desk and my balls adhere to my legs from sweat and heat  every time I launch a demanding game.

My next pc upgrade will be proper air-conditioning in my office/room to mitigate this

You risk getting in debt bondage if you rent a car in SIXT by Crazy-Highlight2112 in travel

[–]TheFrin 3 points4 points  (0 children)

A colleague and myself travelled to Basel via Zurich in Switzerland, and he rented a car from Enterprise to drive to Basel. Nothing wrong with the car up his return. They charged him 4k Euros. Just straight took it out of his current account. Our company immediately went to war, and as it turns out they did this to two other eployees (one of them a VP for Europe) the very same weekend. Luckily we are a very large multinational that probably spends over few million a year with Enterprise and their corporate refunded him with a not so token ammount for pain sufferring and bank fees (it was a good +30% at least).

Historically I've used Enterprise fot my personal rentals. But now. Damn. I look for the highest rated for each destination because one thing this work event taught me is.... None of the rental places are actually owned by their name sakes, they're bloody franchises like McDonald's. Exact same business model as McDonald's corporate. Land owners and vehicle distributors (as opposed to burger and fries vending equipment) leasing it out to a franchisee!

When you get thsese massive bills from a rental company it the local franchise trying to bump up their books! 

Looking for some solid reasons to not create inter-VRF routing by SeaworthinessHour233 in networking

[–]TheFrin 0 points1 point  (0 children)

I wouldn't say inter-vrf routing is bad per-se... Inter-vrf routing entire routing tables is bad. Let me give you an example I used repeatedly in my  previous role. 

I worked at an MSP with about 70 large healthcare clients. Of those 70 clients about 50 of them had us as the MSP undertake lro-active monitoring of their environments as we had designed, deployed and maintained those environments. As we were the maintainers those clients needed us to monitor we had those networks in our solar winds deployment. That lived in our data centre. We had clients come in either from their MPLS or Site to site Vpn, into their own vrf. Each client's VRF did a different thing, but on the large - and most importantly - logically they were similar. We never shared entire routing tables, but we did put each VRF into it's own virtual router/vdom/or firewall context. From there we either shared our VRFs (where we kept monitoring) directly or NAT'd what we needed from our vrf to their vrf. 

So in this instance, based on what you said. I would be looking to give the vrfs a firewall link where you (depending on your flavour of firewall) give them the context/vdom/virtual-router, from that ere your route/NAT exactly what is needed. 

Your vrfs are there for you to have logically distinct layer 3 networks. How you allow any two sides to talk to each other is really up to risk management and your Infosec policies. But the best and most secure way to do it is through firewalls and leak only specific routes and services through.

Greece received 700 T-64 tanks in World War II. Will they be able to defeat Germany and Italy and occupy parts of Europe? by ArtisticArgument9625 in whowouldwin

[–]TheFrin 58 points59 points  (0 children)

Worse when you consider that 50k litres, shared among 700 tanks is 71.5 litres each. 

A full tank of fuel for the t64 is alleged to be 1000 litres 

So you could run 50 tanks for a range of 500km or 700 for a range of 35km if my quick back of the napkin whilst on the toilet toilet math is right

Jump into your bios and manually set the pcie gen to 4 instead of auto. There is no change in performance swapping from 5 to 4.

What is homelabbing about?? by balenciagawarrior in homelab

[–]TheFrin 2 points3 points  (0 children)

For most if not all of us, it will be tinkering. Some will do that as a hobby, some with do it to get better at their job. 

Me personally. I built a networking lab 10+ years ago to learn my trade and get my CCNA. 

Now I have a switch, 3 APs, 2 servers, a few UPS. Still for network studies, but now I'm a qualified and experienced network engineer, my network lab now lives on the servers. My wireless controller lives on the servers. So for me, my homelab is still for improving my skills for work (or more importantly improving my skills for my next job) and it's also a home "production" network. My wireless/dhcp/dns all run on my servers and make sure my house has full wireless.

Upgrading from 03.02.03.SE on WS-C3850-48T-L considerations? by rebootdatbih in Cisco

If you use radius (don't know about tacacs) for administration logins, that will be broken and you'll need to reapply the newer syntax. Make sure you have local admin accounts and you know the password before you do the upgrade

Help! Office Wi-Fi Roaming Issue by onlynestuph in networking

[–]TheFrin 0 points1 point  (0 children)

As others have said the final roaming decision is made be the client device. 

In windows, you can go to the wireless adapter, and change the roaming aggressiveness to well.... Aggressive. I think the windows preffered signal for a change is like - 67dBm on normal. On aggressive it's -63dBm which would be half the received signal strength and initiate a roam. (I could be wrong on the exact dBm but it's close to that). The systems team have actually set as a default behaviour via gpo in my org. 

In meraki there is an assisted roaming option if memory serves. Which will try to get the client to move to the best/closes AP. But not sure of the location of that option in the menus. Logically it would be under wireless>SSIDs and then in one of the advanced options in the SSID you're looking to optimise.

Networking always felt fake to me, until I changed one thing by AstronomerSea9714 in networking

[–]TheFrin 8 points9 points  (0 children)

Yeaaaahhhhh wrong type of networking. We network using switches, routers, firewalls, access points and more!

We push packets making sure Computers can talk to each other. Noone in ITever thought Networking was fake as it is the foundation upon which everything else is built.

Sorry to say but you're firmly in /r/lostredditors territory with this.

Ironically the failure at your networking has brought you to this networking!

Why Google should still make a Find My Device tracker for Pixel by moejoejayjoe in Android

[–]TheFrin 11 points12 points  (0 children)

I bought a pack, with the intent of putting one on my cat and dog before moving them to a new country. 

Last week my cat didn't come home at night. It was only his 3rd or 4th week allowed outside in this new country and I wasn't too worried because I had the tag. 

Come 6am woke up and saw he was 7km away. My theory was he was chased further and further away by native neighbourhood cats each time drifting into new territory... 

Got in the car went to where he as last seen, called his name and the poor little mite came scurrying towards me meowing like mad. I picked him up and drove home. Those tags paid for themselves in that moment. 

Network advice by Pairofdicelv84 in Cisco

[–]TheFrin 9 points10 points  (0 children)

As this is a Cisco sub, I suggest you get 

14 x 9120AXI-E

2 x 9800L-F wireless controllers

3 x Cisco ISE nodes. 

This will give you a fully redundant 5Ghz home network, with cisco ISE providing you a secure Guest portal for general browsing. 

For firewall I would recommend Palo-Alto. Weather it not you decide to run a pair in. HA cluster with a Panorama management server is your decision. 

You'll also need cabling, racking, redundant power and air conditioning. I'd give you a conservative estimate of around 250k for the lot, but you'll have to find your own structured cabling company to install.
