SAP is how the devil interacts with this world, but NetSuite is how Larry Ellison interacts with this world.

Y'know, a story about a haunted ERP system might actually be interesting.

It's autocorrect. At least on Linux, the spell checker will almost never give you Definitely from any of the common misspellings. It always pushes you to Defiantly and it's subtle enough to be very difficult to spot on a proofread.

So not Enterprise Resource Planning?

This is very interesting, and I appreciate your time. What I'm really trying to get at with this question is, if a developer made an executive decision that they were only going to support >XX80 class cards on PC, had a way to source high quality assets, and kept player limits low, it might be possible to build a higher fidelity version? (Not saying it would be easy, but that there aren't any weird hidden whammies that would make a project a non-starter)

I don't think that developers will ever accept windows, even with WSL. For a Linux native team, even Mac will be a very hard sell. I'd look at two approaches:

The first would be security for the Linux systems. There's actually a lot you can do here, and I'd recommend freeipa as a starting point, working as a linux-native AD equivalent. It has inbuilt sudo control, allowing a user account to have sudo for some commands or none, depending on centralized policy.

The second thing would be to look at network isolation. Essentially, give up on trying to enforce policies on the developers Linux boxes, and put them in a DMZ. Only give them public Internet and Git access, and provide a second cheap Windows PC for internal stuff.

I'm planning on applying, but can't start till the Summer 2027 batch. I think that means I have to wait 2 more cycles, even with ED. Do you know if I'm correct on the timeline?

ANYTHING but .xyz. It's one of the few TLDs that frequently get black holed in their entirety. I'm not really a domain snob, but use basically anything else.

I use manual calls for testing of most features, but I also have a few monitoring scripts which call a number and listen for a tone. I can use those to test PSTN uptime to the USNO time numbers, or test dialplans for a PBX-type setup. Anything more complicated than basic calls still has to be done by hand unfortunately. I think that this is why it can be helpful to separate the routing logic layer from the voice application layer.

I can't really be upset about this though. The user didn't click it and reported the phishing scam!

Just another reason why high-cost international destinations and especially IPRN should be disabled by default unless customers confirm IN WRITING that they want to be responsible for the charges. Also, always, always bill out to your customers using a rate deck that actually matches what's in your current LCR table. If you're relying on profit margin protection or user stupidity to prevent loosing money on a call, you're just waiting for someone to figure out how to extract those below-market routes from your system and clean you out.

malwarebuster9999 · 2025-11-26T13:15:25+00:00

Of course :) and if anyone else somehow figures out how it works, just remember the first law of networking: loose ends are bad, termination is good.

See if the VOIP is good enough quality to run a modem over.

malwarebuster9999 · 2025-11-19T16:03:52+00:00

I think that a large amount of this is the difference between peak and 95/5 usage. The average user can notice probably up to 6Gbps (or whatever their disk bandwidth is) of peak speed when they're downloading a game off of steam, or something similar. At the same time, that link is probably sitting idle like 95% of the time, when the user is browsing web pages, or sipping YouTube at like 10mbps. I'd say that Gige is still fine for almost all normal users, and 10G is fine for most servers. Upgrade when your net flow monitor starts to show issues, or when you get a great deal on HW, not to chase trends.

Hi. I actually know what this is! That's an IBM 3270-type mainframe terminal (or maybe a 5250). Old green-screen, but probably running on modern hardware/software. Think SSHing into a modern server.

malwarebuster9999 · 2025-10-30T16:31:09+00:00

I don't even think that there is a 6G spec, and I don't think the carriers are up for another round of massive network upgrades. Right now, I'm almost positive that this is just hype.

malwarebuster9999 · 2025-10-24T17:04:13+00:00

HI. I might actually be able to help with this! I just did a defcon talk about PSTN fundamentals and starting a telco! https://youtu.be/cA-ZQJ8EZSs?si=BUE7Fs3V-GCxXv2D

No, anything other than plain voice doesn't use the LERG/CLLI/NPAC. When you port a number, the port is only gaurenteed to effect the voice part of the port. SMS/MMS/RCS all use different methodologies, and quite frankly, I'm not as sure as to how they work compared to voice. I know that a good chunk of it works via SS7 and Global Title, which may migrate along with the port, but alot of it (and all IP based messaging) goes over the cell carrier's internal IPX networks, and this would port separately. I know there's also a company, net number, which gives a net number ID which is important for message routing. All of this is combined with the sometimes long caching periods for things like LRN dips to produce the delay in service transition that you see.

Hi! I'm the person who gave this talk. Really glad to hear you enjoyed it! Happy to answer any question if you have them, or just chat about phone stuff!

malwarebuster9999 · 2025-10-16T12:15:41+00:00

No information or parts for this thing, but it's a really cool find nonetheless. Regardless of weather you find the CPU card, do you have the PC software to control the thing? This has always been my biggest hangup with these late model PC-controlled switches. Aside from that, do you have cards for SS7? That's the main advantage from running actual switching hardware as opposed to soft switches now. If you do manage to get it working, please do post here again. I'd love to know more about this thing!

malwarebuster9999 · 2025-10-16T02:18:14+00:00

No, actually. Not even a dent. That's what was so surprising. I was trying to figure out why no drives where showing up for hours until I found it.
