Part of my maturing with getting older in addition to the above is that luck is a larger factor than most people are willing to admit. So I'm with you that GTM is just as important as engineering, but execution on all fronts is what ti

These tools are very common in non-nefarious ways for troubleshooting networking, and while vendors set up to serve this space solely as troubleshooting tools, I've also built my own that can sit on a network link and monitor for probl

Not exactly acoustic but reminds me of a high school science project we had one year, something along the lines of put out a candle with a contraption. My partner and I rigged up a balloon to be popped by the candle, and the balloon pop blo

I've seen this point in a few different places and I don't know that it's understood as widely as it should be. So just to expand on why that's the case. As a net producer of energy right now, the US produces more than i

Just in case any of the authors read HN, I'm getting a pretty crazy rendering bug on this page, where a bunch of the contents are redrawing up and down by a few pixels. It seemed to go away with resizing the width a few times, but I di

Sorry, I didn't mean to imply tariff's were the exclusive cause, just a reminder that an additional factor is large tax increases.

Good ol proxy arp, also ~20 years ago I took out all cellular internet access in Canada. Luckily it was in the maintenance window and I acted pretty quick, so hopefully no one noticed the couple minutes of outage at 2AM.

And even if there are new ETFs like this, will ETF customers bother to move at enough scale. It's like the old quote for buying IBM, no one get's fired for returning the benchmark, so if it's the benchmark adjusting the way t

And to try and expand on why an index would include a waiting period in it's rules, my limited understanding is it's to give the public markets time to follow the company and review several quarters of financial results to stabili

I'm a little bit more on the fence with the work sample interviews having designed them and also interviewed through them. I've also done my fair share of "traditional" tech interviews, all at startups, never FAANG. As a

And the way they verify you are doing what you say you are doing is by asking you to provide evidence, which is usually pretty easy to demonstrate that a policy was followed once or twice, a lot harder for them to pick up consistency issues

Yup, I thought it was great. Although one concern I always had in the back of my mind was where is the line drawn. Such as if an adversary gains access to one of my orgs accounts and does something similar, do we get 100% taken out.

>That’s assuming your vendor was pentesting AWS systems. If you meant you hired a vendor to pentest your own systems on AWS, that’s of course a totally different matter. Sorry for being unclear, the vendor was attacking our organization

by kevin_nisbet 5mo ago
Do they? The only anecdotal thing I've seen is we hired a vendor to do a pentest a few years ago, and they setup some stuff in an AWS account and that account got totally yeeted out of existence by AWS if memory serves.

Sometimes it's mostly about taking an interest, reading or understand the legislation, and making a really good case and argument to the government. I don't think I can claim credit because I'm sure I wasn't the only one

I'm not an expert on the baseband implementations, but I have the same impression as the parent, that in the 3GPP protocols the devices location can be requested and it's processed without any OS level interaction. How that maps i

Absolutely, I just don't know that this can be achieved over the Diameter/SS7 network between carriers, which the report was alleging access to the RAC/TAI and Cell ID's. So if the threat actor has different level of acc

Yup, sorry I didn't bring this side up because the article was mainly talking from the perspective of pulling the LAC/TAI from generating messages in the SS7/Diameter networks. If we want to include what a carrier can do or w

This was a fairly interesting read, but some of the claims struck me as fairly circumstantial. I ended up almost writing a novel of a comment, but will try and save everyone from that by summarizing. I started my career in Wireless Telecom,

On this side of the equation I think you start pulling in customer context and risk analysis on the downside. What is the churn risk for operation at 99% vs 99.9% availability. If your site is for B2B and impacts customers own operations or

The tables in the link do a good job of outlining this, 11.9% while an interesting headline number, 11.9% increase over nothing is still basically nothing. However, with the tables going back to 2022, it's almost 100% increase of busin

Agreed, and this is where I think some more nuanced and conscious use of tech debt can be used when applicable. It might be OK to place some bets on an initiative or feature, but if we all understand we're placing a bet, this is an are

I'm not commenting too much on the details of the article, but the premise does resonate with me. I would argue all the engineering teams I've been on do not spend enough time thinking about how much a piece of work will cost to e
