kraloson Advent of Sysadmin 2025

It would be cool if we could SSH into the temporary host (I'm guessing these hosts currently aren't internet connected to avoid abuse so might not be possible or require some super careful firewalling)

    imagine typing in a terminal...
    you want to delete the previous word so press ctrl+w...
    actually you're in a browser; the window closes...

:sadness:

kraloson Wasting time in tech interviews

As an employer, we are always trying to improve our technical interview. At this point in time we've found the best approach is to look at the ticket board and think "If I had a new developer, what could they work on?". Then come up with a single real world question and ask the candidate this during the interview. The question should allow for a junior or senior to give an answer where the depth of the answer would likely vary much like the feedback on a hypothetical peer review would. We try to avoid anything requiring too much business domain knowledge. You should be able to explain the scenario to someone off the street (non-developer). We then have a face to face (or screen share) discussion about the problem, any questions or scoping and the approach that could be taken like any real developer would if they were given this as a ticket.

As an example:

---

We have an existing job management system to track and update the progress of warranty repairs (e.g. whitegoods). Sometimes parts need to be ordered to complete a repair. If we wanted the job system to book and track parts orders into third-party warehouse management systems; how would you address the following?

- Credential management

- Data types and their life cycles

- Sources of truth e.g.

    - Customers who have purchased whitegoods are the source of truth for new jobs

    - Our staff operate the job system and our clients (manufacturers) are the source of truth for parts

    - Tradespeople operate the job system and are the source of truth for new parts orders

    - Warehouse staff operate the WMS and are the source of truth for stock levels

- Required/Optional API calls and their triggers

- Fault tolerance and monitoring

- Compensate for variations/shortfalls in existing WMS APIs (in some countries we use a 3PL)

WMS: Warehouse Management Software

3PL: An external company who operates a warehouse and dispatches items on your behalf. These companies may do so for multiple tenants and have established staff, processes and WMS.

kraloson Please put units in names

We also strictly stick to SI however we usually say kilograms in var names to be clear.

Haven't come across temperature however we would probably stick with kelvin.

We use a strict set of units in databases and while processing, conversions are localized if necessary only at the view layer.

We also only use UTC for date/times.

We only use E164 format (without spaces etc) for phone numbers: e.g. +12345678901 for an example number in OH, US. see National format https://libphonenumber.appspot.com/phonenumberparser?number=...

We only use iso3166-1 country codes and iso3166-2 region codes and translate on view.

kraloson Fisher Price Chatter Telephone with Bluetooth

All I want to know is, can I Bluetooth audio device it into my work laptop's SIP client? It could sit inside webcam view for those important conf calls

kraloson Please log in with router's password

> If they really needed access to the router remotely, it would be much saner to expose an SSH server with pubkey-only access or VPN, both with brute forcing protection, and allow tunnelling to the router UI only from the LAN side.

any chance you can explain that to my mum?

kraloson Please log in with router's password

Hey Mum! I can see my router from here!

kraloson When Bitcoin miners take over a town (2018)

Most of the bitcoins i bought are super shiney! did you get dull ones?

kraloson When Bitcoin miners take over a town (2018)

platinum is more electrically resistive (less conductive) and more expensive than gold

USD, EUR etc are also "fundamentally worth $0". Fiat currencies and crypto currencies are just a median for representing value for real goods and services. What's unique about crypto currencies is the distributed method of transacting and therefore the inability for them to be regulated. The whole financial industry, is fundamentally a massive waste of humanity's resources. Fiat currencies are regulated, regulators are a target for bribery, deals are made etc... Cryptos are a massive waste of electricity. Decentralization is a great way to curb corruption and restore a natural economy but we need to solve the electricity problem. The electricity problem came from the mechanism chosen to "fairly" distribute the initial pool of cryptocoins based on mathematical effort.

kraloson Ask HN: What are you learning?

I studied vector mathematics in high school; matrix operations, dot product, cross product etc. All through these lessons I thought; "what a stupid thing to learn, who would ever use this?". Then after school I became a CAD/CAM developer and spent most of my time working with vector mathematics. It was with the help of OpenGL so I technically didn't need to understand how these operations worked under the hood but yep... what a stupid thing to learn indeed.

perhaps you should read the source rather than rely on what OP infers

kraloson New Dell XPS 13 developer edition now available

https://en.wikipedia.org/wiki/Intel_vPro

Intel vPro technology is an umbrella marketing term used by Intel for a large collection of computer hardware technologies, including Hyperthreading, Turbo Boost 3.0, VT-x, VT-d, Trusted Execution Technology (TXT), and Intel Active Management Technology (AMT).

~~It means it doesn't have VTd / VTx hardware acceleration on the CPU. You can run VirtualBox however it will be slower. When I first saw "Developer edition" I thought; that must just mean it's got Virtualization hardware acceleration and loads of RAM for running VM's etc... This branding makes no sense to me.~~

I just looked up the 15W parts on Intel ark (i7-8565U, i5-8265U, i3-8145U) and they say they do have VT-d and VT-x...

kraloson Ask HN: Why doesn't google.com implement DNSSEC?

Does anyone know why Google hasn't implemented DNSSEC on google.com ?
