insomniacity commented on Allianz Life says 'majority' of customers' personal data stolen in cyberattack   techcrunch.com/2025/07/26... · Posted by u/thm

This isn't an offshore situation though.

I've worked with Allianz's cybersecurity personas previously on EBRs/QBRs, and the issue is they (like a lot of European companies) are basically a confederation of subsidiaries with various independent IT assets and teams, so shadow IT abounds.

They have subsidiaries numbering in the dozens, so there is no way to unify IT norms and standards.

There is an added skills issue as well (most DACH companies I've dealt with have only just started working on building hybrid security posture management - easily a decade behind their American peers), but it is a side effect of the organizational issues.

That is their choice though - they could setup a technology services subsidiary, and then provide IT services to the other subsidiaries, transparently to the end users in those subsidiaries.

I experienced something similar at Nokia around the time things were starting to go bad (due to competition from Google and Apple). I got caught up in one of the earlier layoff rounds. As I've been able to reconstruct since then what happened was roughly that:

- I got a excellent performance review and a small raise. All good, keep on doing what you are doing! I was pretty happy.

- Nokia started to prepare for layoffs and gave units targets for numbers of people to lay off and amounts of money to save. They tried to spread the pain.

- Because of my team's multi site setup the choice came down to cutting at one of two sites. They picked my site. Management was concentrated at the other site.

- Because I was at the higher end of the spectrum in terms of salary, I was one of the natural choices for laying off. This was just done based on the numbers and had nothing to do with performance.

So, my bosses boss flew over to give us the news and that was it. Nokia was pretty nice about it. I was put on immediate gardening leave, I got the usual severance payment based on time served, and a decent amount of start up funding in the form of a grant.

Since things were chaotic, other teams in the same site were still hiring new people with roughly the same qualifications. I was actually bucketed in with a project I wasn't even a part of. That whole project got shut down and apparently it was convenient to pretend I was working on that just so they could avoid firing other people in different parts of the organization. Somebody had to solve a big puzzle and I was a piece that fit in the right place. It wasn't personal.

In retrospect, one of the best things Nokia could do for me was firing me. I was coasting and the whole thing forced me to rethink what I was doing. If you are late thirties and a bit comfortable in your job, you might want to make a move. Or at least think about what you would do if you were forced to suddenly.

Lesson learned: job security is an illusion and employment relations are business relations. Don't take it personal. These things happen. Part of a high salary is insuring yourself against this kind of stuff and dealing with it when it happens. Part of the job.

This is fascinating? What was it in absolute terms, or relative to your base salary?

Did you have to have a viable startup idea and it was paid to the incorporated company? Or was it just extra cash in your personal bank account?

Did you do that, or did you just get another job?

I wonder what the implications for all the s3-like APIs is going to be.

Good point - plus the conditional writes recently announced. Did anyone else implement that?

If it's text-heavy I'd recommend Obsidian

So the goal would be to eventually move that graph into running code and query it. But it’s never going to be large - easily fit in memory.

Obsidian is PKM right? Does it have the idea of labels on the edges?

Tacking on a related question - what software should one use to interactively create/update/see a small graph?

Thinking specifically about a graph of knowledge, so will be an iterative process.

Just looking for anything more than a text editor really!

insomniacity commented on Ask HN: Why is it so hard for devices to determine WiFi network health?    · Posted by u/jc_811
Grimeton · a year ago
First of all, the problems you describe belong to different layers in the OSI stack [1]. You need to understand this stack, to understand what I’m talking about.

The first one belongs to layer 1 of the ISO/OSI stack.

    As I’m leaving a zone with WiFi, the signal drops to 1 WiFi bar for way too much time and tries to remain on the network even though it no longer serves. Forces me to toggle WiFi off so my phone switches to cellular data
Yeah well, WiFi depends on the propagation of radio waves and as it’s bi-directional it also requires that both ends can read the transmitted radio waves of the other side. This can be influenced by multiple factors, but there are three basic things that happen to affect it most:

1 - Transmit power. The higher the power used to transmit the information is, the further it usually (!) reaches. One factor is the outputted power of the transmitter, while another factor is the gain produced by the antenna (ERP/EIRP) [2].

2 - Antenna/Receiver Sensitivity: The antenna is not just responsible for transmitting the information, but also to receive it and in case of directional antennas, to fade out interference. There are many different antenna types [3], [4],[5] and to explain what they are and what they would be way past the scope of this.

As a golden rule: If the antenna matches the wave length of the used frequency [6], is mounted in a way so that it fits the polarization [7] and there’s not much interference on the channel, you have high chances to get a good connection.

3 - Interference. When you check the frequencies WiFi operates on [8], you’ll see that there are all kinds of services/devices working on those frequencies. Even commercial radar on 5GHz, which is why 802.11a has a mechanism to detect radar and disable itself.

So knowing all this, here’s a simple scenario:

The WiFi access point transmits with a higher power, so it reaches further and can still be read by your phone, while the phone itself transmits with lower power and cannot be read by the access point anymore.

It can also happen that authentication to the network is working but then you’re not seeing any data anymore. This comes from the fact that the more data has to be transmitted, the bigger the packet size is, the longer the transmission time becomes. And the longer it takes to transmit the data contained in one packet, the higher the chances that there is some interference, rendering the transmission unreadable at the other end, requiring a retransmit and a retransmit and a retransmit and a retransmit and a retransmit …

The phone now waits for certain timeouts before it considers the network dead. That’s what you’re facing.

There are a million more scenarios why the receiving end cannot read the data, but in the end it always boils down to not being able to read the other side.

The second problem belongs to layer 1 and 3 of the ISO/OSI stack:

    It connects to a public WiFi I’ve used before, has full WiFi signal strength, but in reality there’s no service because to actually use the network I have to login, accept terms, or something along those lines. And if I don’t do that I’m unknowingly without service because my phone can’t tell this network isn’t actually working
The bars are usually just the signal strength [9] of the received signal and don’t say anything about the readability of the information that is transmitted. So if the signal is strong, the bars are much…

Internet connectivity however is tested via layer three and up, e.g. by requesting a specific website/url that either returns a http status code in the 200 range for unlimited access or a 302 redirect to a captive portal [10] where you have to login to use the network.

If the latter is not implemented correctly or not implemented at all then your phone again goes through certain timeouts and multiple re-requests to see what’s going on.

Especially when the http request is black-holed as long as you’re not authenticated, the phone will sit there and wait and wait and wait… There are a lot of - excuse my french – stupid network administrators that think that black-holing everything is a good idea, while an ICMP based response is a much better one.

The last one is purely based on your settings:

    Similar to point 1, my phone will pick up a WiFi network that’s far away (eg my home network while I’m at my neighbor’s house) and grasp to that weak unusable 1 bar of WiFi signal forcing me to toggle WiFi off (or just forget the network if it’s one I don’t commonly use)
You can set certain options like “auto connect” or “free of charge” as options for the network. Those are used to tell if a network is preferred. Same as the average connection duration to a certain SSID/Network. This all affects the choices of your phone.

So your home network with a high average duration of connection, free to use, no traffic limit and auto connect, beats the neighbor’s network when both are visible. Lowering the transmit power on your network could help to solve that issue…

There are a million more reasons and the things are way more complicated “under the hood”, so this answer barely scratches the surface, but should give you an idea what to look for.

If you’re interested in learning more about radio waves, their propagation and how the technology behind it works as a hobby, then I recommend looking into becoming a member of the ham radio community [11]. There should be a local representation in your country, too [12].

To acquire a license you have to learn about all these things in greater detail...

I like this way of putting it. I find a LOT of technology questions and problems can be easily answered once you have a good understanding of the layers of the stack, whether that’s OSI, Kubernetes, or a large enterprise cloud platform on top of AWS.

Say you're a small or solopreneur company, and you don't have any enterprise customers yet.

What do you put on a features/pricing page to help you start finding out what your enterprise customers might actually want? (Not the generic stuff like SSO and audits, but specific to your product/market).

Just a generic "Don't see the features you need? Email us!"?
