FlixTrain | Technical Expert Onboard Connectivity | Berlin, Germany | ONSITE (hybrid) | Full-time

FlixTrain is on a mission to make long-distance rail travel affordable and sustainable across Europe. Every passenger we shift to rail matters, and the onboard connectivity is a key part of what makes people switch.

We're hiring an Onboard Technology Manager to own everything that keeps passengers connected and crew productive on the train: Wi-Fi and network infrastructure, onboard units, and mobile devices for train staff. As satellite constellations and 5G redefine what's possible for high-speed mobile connectivity, you'll help set the direction for the technology being adopted on the largest non-governmental train fleet: writing specs, defining network architectures, monitoring live performance, and driving improvement projects from their conception to the finish line.

The role is highly cross-functional. You'll work with internal partners (operations, customer product, and rail engineering) and external ones, such as tech vendors (Icomera and Advantech) and train manufacturers (Siemens, Talgo).

What we're looking for:

- Bachelor's or Master's in Telecommunications, CS, Electrical Engineering, or similar

- 2+ years hands-on with network architecture, Wi-Fi systems, or Mobile Device Management (ideally in rail or a similarly complex environment)

- Strong troubleshooting skills on complex networked systems

- Comfortable leading cross-functional initiatives and communicating clearly with both engineers and non-technical stakeholders

- Fluent German and English (internally, English is preferred, but German is often mandatory when working with suppliers and regulatory bodies)

Perks: hybrid office/remote work model, up to 60 extra remote days/year from abroad (work from anywhere), 12 free FlixTrain travel vouchers/year + 12 for friends and family, mental health support, L&D budget, mentoring program.

> If the device was validating the server certificate, it wouldn’t make it this far, so that shows that our certificate was accepted.

One more very good reason for preventing requests to "the cloud".

However, I find it funny that the lack of proper certificate validation (which is a security issue in principle) is a pre-requisite for the "de-cloudification" process.

I chuckled.

Very interesting!

It would be even more appealing if you could show a test case where a high level metric (e.g., wifi download speed) improves with one of your lenses compared to a baseline scenario without lense.

Also, I expect the dielectric properties of the printing material will affect the design.

Which printing material have you tested exactly?

Do you know how much the performance changes when cheaper alternatives is used?

Might be Morse code

> Fanless 0 dB design

Note that 0 in dB scale indicates a 1:1 ratio with something, and not a zero in linear scale. Indeed, a zero in linear scale corresponds to -infinity in dB scale.

Fairphone 4 has been my main and only phone for several months now. Great experience, very good battary life. Performance-wise, I haven't noticed any significant difference compared to traditional phones. The only drawbacks might be the camera and thickness, but honestly I don't care much.

Of course, much depends on your use case and expectations. YMMV.

Don't know much about the invisibility cloak. But in wireless communications the "better smart mirror" idea is being investigated to achieve arbitrary reflection directions that defy Snell's law [1][2]. The objective is to hang these "mirrors" on walls/buildings and reflect the incident power towards areas where the reception is poor.

One issue with SVD is its significant time complexity compared to, for example, the Discrete Cosine Transform used in JPEG

The author raises an interesting argument, but I don't see how the "maintainer perfectionism" issue is specific to Rust in particular.

Indeed, the two examples they mention are both related to Rust somehow, but is it enough to generalize to the whole Rust ecosystem?

An alternative could be to create another zero-sized type for NaN and Infinity

Interesting point. However, I believe frequency trading relies on connections with extremely low latency, while satellite links are characterized by high Round Trip Time.

If you're looking for something Arduino-compatible, you should consider the RFM9x family of boards, based on the SX1276 LoRa chips.

Breakout board from Adafruit: https://www.adafruit.com/product/3072

A number of ways are listed here [1]

1. With dmesg

dmesg -wH | grep 'page tables isolation'

2. With /proc/cpuinfo

grep cpu_insecure /proc/cpuinfo && echo "Patched" || echo "Unpatched!"

Yes.

The issue is actually being worked on. For example, the draft RFC for fallible collection allocations is now in final comment period [0].
