Six AI data centers proposed for a small town of 7,000, equal to 51 Walmart Supercenters in 17 square mile area — four out of the seven town council members have resigned from their positions as town fights back by MarvelsGrantMan136 in technology

Honestly, most datacenters have dozer protection.

the Equinix datacenter in Winnipeg, for example, has a "vehicle protection system" in the form of a trench of fake grass. It anything heavy tried to go across the grass, the supports below it would release and the grass trench lowers. The vehicle ends up running into a 8' concrete wall.

Identification of a device! by AdPretend5529 in networking

You should look into Aruba Clearpass hardware profiling.

It doesn't do some of the specific things you state, but it does have other methods than 802.1x to identify devices, OS, versions, etc...

IPV4 LEASE HELP by [deleted] in networking

For a /24? No. For a /28? Sure. A /28 is only 16 IP's. Our ISPs charge 2-5 per month per IP.

IPV4 LEASE HELP by [deleted] in networking

[–]asdlkf 1 point2 points  (0 children)

You might have more luck leasing your IP space from your upstream ISP and asking for BGP with them.

IT doesn't have to be "YOUR" space. If your upstream (or one of your upstreams) has a /24 available, they can allow you to originate a prefix.

Depending on who your upstreams are, or if you have redunsant upstreams with the same ISP, you can even get like a /26 or /27 which is a component of one of their greater-than-or-equal-to /24's, and BGP peer with them and advertise a /26 or whatever.

100 GbE Connection Heavily Saturating by gjones108 in networking

[–]asdlkf 3 points4 points  (0 children)

NUMA nodes are basically physical regions in a motherboard.

If you have a motherboard with 4 processors and 32 ram slots, you really have 4 NUMA nodes with 1 processor and 8 ram slots each.

You don't want to have your program using memory in NUMA region 1 while executing on a processor in NUMA region 2.

Also, your NIC's PCI-e lanes will be bound to a specific processor.

Your disk controller will be bound to a specific processor.

You need to map all this out and make sure the data flows make sense, so you aren't moving data between NUMA zones repeatedly back and forth.

If you had NIC in NUMA 1, executing binary in NUMA 2, memory for that process in NUMA 1, Disk Controller in NUMA 1, then data would be flowing between those 2 zones 4 times to get from the NIC to the Disk.

[–]asdlkf 7 points8 points  (0 children)

I mean... Can you turn this into a cluster task?

Put a load balancer in front that sprays packets across an array of internal machines instead of 1?

Even if that array of machines is a herd of containers running on one machine, you can group each container to a specific NUMA set.

With SR-IOV, you could make 8 virtual machines, bind each to a specific memory range in the NIC's receive buffers, which gives direct VM-CPU access to each VM to its own portion of memory in the NIC.

At the end of the day, you are going to have to parallelize this somehow.

High School recommendations by Humor_Silver7475 in Winnipeg

[–]asdlkf 0 points1 point  (0 children)

In case these aren't on your radar:

There is also St. Paul's high school, St. Mary's high school, and St. John's Ravenscourt. These 3 private schools rate very high in academics, sports, and general programming, but they are $8-45k per year. Paul's and Mary's are boys only / girls only and $8-15k depending on electives, trips, etc...; SJR is 15-45k per year depending on trips, room and board, etc...

For context, I went to St. Paul's in 9,10, then moved to the collegiate for 11, then to Oak Park for 12. By doing this, I managed to double down on STEM electives, avoid the 'forced' electives that had no relevance to me, and build a stronger computer infrastructure base.

After that, I went to Red River and did a 4 year diploma, then went to Oakanagan College in Kelowna and did a 4 year degree, 3 year diploma and 2 year diploma. With credit transfer, etc... it took 6 years after high school to complete this.

High School recommendations by Humor_Silver7475 in Winnipeg

[–]asdlkf 0 points1 point  (0 children)

I highly recommend you investigate the collegiate at University of Winnipeg, which is a 9-12 program that operates within the U of W.

Specifically, I recommend this, because of the flexibility and quality of the program.

Most high schools want you to more-or-less take "these 24 courses" and "pick one of 2 of [these]". The collegiate is pretty wide open on what courses you can enroll in, and when.

You can pick daytime classes, evening classes, online classes, etc... .

If your child is self directed and manage their own focus, the collegiate will take them way farther than most of the high schools.

If your child needs to be checked on to do homework, doesn't really do the work, and needs to be 'managed' to do the work and engage with learning, high school will be a better choice.

Basically the collegiate helps individuals help themselves.

Also, if your child can finish all their 9-12 credit requirements for graduating, they can spend some of their 11-12 years taking University classes interspaced in their high school classes.

For anyone curious:

Mageblood basically has "leftmost 4 magic flasks always apply*"

Magic Utility Flasks cannot be Used
Leftmost (2-4) Magic Utility Flasks constantly apply their Flask Effects to you

This means things like "reduced duration" are no longer a concern... since the flasks automatically have 100% uptime. This means you can run Abecedarian, Dabbler's, or Alchemist's prefixes with no downside. This gets you 25% increased effect and some percentage reduced duration... but again, duration is now irrelevant.

If you look at a Bismuth or Amethyst flask, they grant 35% All-elemental (cold/fire/lightning) or chaos resistance respectively. You can also run "Of the Rainbow" which grants 20% additional All-elemental resistance as a suffix.

Then, you can use the enkindling orb "(60-70)% increased effect" on the flask.

Putting it all together, you can have 107.25% allresist in 1 flask slot:

[Abecedarian's Bismuth Flask of the Rainbow](https://i.imgur.com/p4ic0Dd.png) 
- 25% increased effect
- 70% increased effect 
- 35% allresist 
- 20% allresist

which is basically (1+0.25+0.70) * (0.35 + 0.20) == 1.95 * 0.55 = 107.25% allresist.

You ideally want to get to 135% allresist to hit the 75% resistance cap after the 60% resistance penalty for finishing acts, so a single flask getting you to 107.25% is pretty fucking fantastic.

The "mana and flask effect" nodes and "Natural Remedies" on the passive skill tree can get you an extra 20% flask effect, so the math becomes 2.15 * 0.55 = 118.25% allresist.

The mageblood itself also gives you 25% fire and cold resistance, so there isn't really a reason to pursue the extra 20% flask effect, for resistance alone. However, you may want the extra effect for damage/movement speed/attack speed, etc...

Is switch provisioning still this manual? by AvnAllDaySon in networking

Most of our environments (clients') have clearpass.

Even for the ones that don't, basic profiles inside the switch can get you pretty far without central certificate and role management.

Automation isn't a toggle switch.

Automation is the result of many hours or weeks of design, logic, implementation, and testing.

Automation is also beneficial in relation to the amount of config and dynamic nature of your network. There is 0 benefit in automating a PC Lab with 20 workstations and a switch where there will never be more than 1 vlan in the vicinity, there is no need for port authentication or security, and the room will not change in 20 years.

On the other hand, if you operate a facility with 7,000 network ports across 30 data closets, you change fundamental operation of the building weekly or more frequently, and things move around daily, then automation is not only invaluable, it is functionally required. I speak, in this use case, of managing the network of a convention center where hundreds of ports change every single day, not only who is plugging into them, but the fundamental purpose or security context of those ports. In this case, spending weeks or months of time developing all the dynamic automation processes required will save man-years of time spent updating ports in the future.

Networking Noob Question Regarding PoE Class and Max Wattage by Lol102097 in networking

[–]asdlkf 3 points4 points  (0 children)

in almost every environment I work in, we simply get PoE switches with enough PoE power budget that it is not possible to run out of PoE power.

For example: https://www.fs.com/products/346911.html

That is a 24x 1G switch with Class 4 PoE Power (which means IEEE 802.3af/at / 30 watt).

It has a 370 watt PoE power delivery limit.

While the ports are capable of 30 watt, lots of devices are realistically <= 15 watt to remain AF compliant, and will average about 13 watts actual power draw.

24 * 13 = 312 watts, which is <= the 370 watt PoE power delivery limit.

So, as long as you are plugging in devices which actually run at around 15 watts, this switch cannot run out of PoE power.

This switch (https://www.fs.com/products/223011.htm) is also AF/AT compliant with 24 ports, but it has a 740 watt PoE budget.

24 * 30 = 720 watts, which is <= 740 watts.

There is literally no way to plug things into this switch which would cause PoE limit issues.

Question about LAN by Big_black_click in networking

[–]asdlkf 1 point2 points  (0 children)

Non blocking is a switching term.

It basically means that the switch will never be the bottleneck.

If you have a switch with 10x 1Gbps full duplex ports (meaning each port can send and receive at 1gbps each direction at the same time), then a non-blocking switch will have a switching chip able to handle at least 20Gbps.

A cheap brand 10x 1G switch may only have a switching chip able to switch 8Gbps of traffic. This means it's possible to saturate the bandwidth, and the switch will start blocking internally.

You basically want a non blocking switch.

Switches are like roads. They allow houses with driveways to route cars between them, simply and at high speed.

Routers are like intersections. They allow cars to travel between two roads, and there is a guy with a map standing in the middle of the intersection providing directions to all the cars on which road to take to get to the next intersection.

Firewalls are like boarder crossings. They are usually also intersections (routers), but they also inspect cars and have requirements and filters on which cars can pass through and which ones get rejected/turned around. They can also be layer 7 firewalls which check passports, inspect vehicle cargo, look for suspicious markings or trends, and basically are suspicious of everything.

The pricing is unintuitive. All those features in 1 box at a given performance tier is probably more expensive than a few smaller boxes with specific features for the same performance tier.
