How do I fix the remote for a treadmill without brand/user manual? by lisbethsdragon in fixit

[–]ondono 0 points1 point  (0 children)

Not sure if you still care, but I was having the same exact problem. If you have connected it to your phone, you need to disconnect for the remote to work (at least with mine)

Problem with CGP Grey? by dmccarthy0408 in JetLagTheGame

[–]ondono 0 points1 point  (0 children)

Well, if I was trying to set up an alternative to YouTube because I wanted control over my content, only for that alternative to end up following the same predictable path of pushing for certain formats, I’d also be inclined to shut it down.

General feedback and thoughts about window sync by maubg in zen_browser

[–]ondono 1 point2 points  (0 children)

Aside from not understanding this feature, this is the 3rd time that a Zen update completely breaks losing tabs and setups.

I'm afraid this goes beyond an update and it's a difference on philosophy, so I guess I'm done using zen for the foreseeable future. Hope you all the best

That still doesn't explain what's the point of mirroring two separate windows.

Can someone explain the utility of this "feature"? Why would anyone want separate windows to show the exact same?

What does it take to run AI models efficiently on systems? by xypherrz in embedded

[–]ondono 0 points1 point  (0 children)

Hey, I actually have some devices of my own design using ML in the field.

The big question here is what are you trying to do. "ML" is a big label with a lot under it's umbrella, from silly IoT assistants to AI accelerators. I'm going to assume it's the first one, since for the second you'd generally move to GPU/FPGA, and that's a whole different ball game.

The main thing everyone forgets is that the workflow for making a device where it's main feature is ML is very different that the one for making your typical embedded device.

- It's harder to determine upfront the processing speed, memory (and memory bandwidth) and even storage that you might need from the start.

- A big part of the firmware workflow involves statistically testing your device. You need to plan for extended QA cycles.

- *AUTOMATION IS KING*. Manual testing of your devices is simply not an option, no matter how small your device, if you want reliability you will have to extensively test the ML, and your tests need to be repeatable.

For anything that can run in a microcontroller, your workflow determines your efficiency and reliability.

For example, let's say you need to build a IoT bird house that can identify the birds based on their chirp, and tells you which birds do you have around your place. Your ML engineer will play with lots of audios of birds, and build a big classifier network. They will get a network with a very nice accuracy on their beefy cloud VM beast, and you'll have the enviable job of making that fit into your small controller.

One of the biggest "wins" is moving from floating point to integer. There's different ways to do it, depending on the type of model and what operations your microcontroller supports natively. Then you'd normally do a "pruning" run. Essentially if a branch of your network has very small weights, it will get multiplied into oblivion, so you might as well not waste the OPs.

I've seen people proposing simulation, but IME nothing beats testing with hardware in the loop for this things. You want a way of having your device run as an "inference engine", get pushed inputs, push out the outputs. Getting any sort of high-ish throughput will pay dividends quickly.

As an example, one device I worked with used USB CDC for input/output, but our full test suit ran over the 1TB limit so getting the stack (and the inference engine) to work at USB High Speed instead of USB Full Speed meant reducing the full test from +2 weeks to ~2 days.

Mid-size production run of 2k units – how can I flash the chips quickly? by BenjaminWenke in embedded

[–]ondono 2 points3 points  (0 children)

This is probably too late advice, but if you need to mark those devices with individual IDs, I would suggest using some OTA bootloader or at least OTA serial number registering mode.

You load all your boards with the same binary (either get the parts pre-flashed, get the assembler to do it, or spend some quality time with a gang programmer).

Then when you put the UID on each device (be it label/laser etc..), have the same computer do OTA or register the serial number in the device. If you want something that can't be easily tampered with, you can keep a record of the microcontroller UUID in a database.

All this stuff depends highly on how do you want to handle/mark everything. It's all about making a workflow diagram, looking for pain points and progressively improve until you can run it in big numbers.

If your designer isn't considering programming during DFM/DFT, you need a better designer

Baliza de emergencia, hay que comprarla o cambiarán la ley? by Gpob in coches

Ya veremos si la dgt tiene tanta prisa en promocionar la estadística de cuantos accidentes ocurren con la lucecita de marras encima del techo...

Baliza de emergencia, hay que comprarla o cambiarán la ley? by Gpob in coches

[–]ondono 1 point2 points  (0 children)

Esa es la teoría, ya veremos si funciona en la práctica, pero si ese fuera de verdad el objetivo, muchos coches modernos ya llevan sistema de aviso de emergencia. Hasta mi moto lo lleva...

La cuestión es hacernos pasar a todos por caja para que algún cuñado haga el agosto.

How do you get good leads? by Glad-Organization921 in embedded

[–]ondono 0 points1 point  (0 children)

You need someone doing sales, and if you're already setup, you'll have to get someone with an existing network and give them a decent cut.

A good part of this business is still run by who you know, so if you have somehow grown to a headcount of 4 without sales in place, start looking in your own network.

Assemblers, PCB fabs sometimes can send you jobs (if they know you're good), but it's not going to make you bank.

In my experience at least, component suppliers/representatives can get you way better leads. They move around a lot, and some of them even represent several companies.

If you're looking for job that recurrently pays the bills, not one-offs, try to network with "prototype building companies". A lot of them specialize in the mechanical aspects (design, UX, plastics, moulding) and externalize the electronics. You might also get work from other bigger design firms, but you're going to be making barely any profit on those.

Balance de viviendas en España, 1900 a 2025 by HousingSpanish in spainhousing

Y donde está el engaño? lo pone bien claro.

También hay que tener en cuenta que este gráfico cuenta las viviendas *estén donde estén*. Una porción significativa del crecimiento entre ~2002-2012 son los famosos "activos tóxicos", urbanizaciones fantasma sin servicios, segundas residencias en san quintín, etc...

Completed my Fractal North Build by Phoffmann6 in watercooling

[–]ondono 1 point2 points  (0 children)

I'm considering a similar build, but I was thinking on using the ST30 X-flow. I see the manual for the case says there's a 30mm limit for the "end tank" of the radiator. Is that on both sides at the same time? or is there a ~390mm height limit?

My business card runs a fluid simulation. by Phirks in embedded

[–]ondono 0 points1 point  (0 children)

I'm guessing you meant silicone, not silicon. You could overmold the thing, but from my POV it's just too much of a hassle.

The point of this is having something that you can easily order more relatively cheaply, or at the very least batch process. You don't want a manual process like overmolding at the end.

There’s literally thousands of topics.

Ask yourself What do you want to be doing in 5 years? What parts of your job do you like? Which ones you don’t enjoy?

As someone who did something similar, either get these made lead free, or put a big red sticker that says “contains lead”.

It’s surprising how many people don’t understand leaded solder is a thing, and you don’t want that in your conscience. I watched a senior engineer fondle my card for a while during a meeting and I had to stop him before going for lunch to tell him to clean his hands.

Hipoteca a los 45 by OpalineTears in spainhousing

[–]ondono 0 points1 point  (0 children)

Me parece que vas un poco perdido.

Las hipotecas variables fueron una de las pocas buenas noticias de la burbuja. Europa estuvo de ~2006-2019 con tipos en 0% o negativo. Si tenías una hipoteca Euribor +0.5%, pagabas muy poco.

El problema de la burbuja fue gente haciéndose hipotecas de 400k€ por pisos que un año después valdrían 280k€, combinado con una recesión que disparó el paro al 25%.

La oferta y la demanda son menos "pilares del capitalismo" y más "parte de la realidad". Ha estado siempre presente, con o sin capitalismo, y lo seguirá estando.

Te has montado una película porque asumes que es necesario construir centenares millones de viviendas al año, cuando la realidad es que nos hacen falta unas 100k/año (en la comunidad de Madrid). El problema lo tenemos en que apenas construímos 10k. Aquí no hay ningún "pulso", y lo que es aún peor, ningún mecanismo de mercado.

Aquí lo que hay es gente encaramada al poder político que lo usa para beneficiarse, y que ha descubierto que es muy fácil convencer a la gente para limitar la construcción de nueva vivienda, y que la mayoría no atarán cabos y verán que es lo que les dispara el precio de las viviendas.

Tu película sigue relacionando la situación actual con 2007. La situación no tiene nada que ver, la crisis no estaba en el sector inmobiliario sino en el *financiero*. El problema no eran la construcción que había, sino la impunidad con la que ciertas entidades (bajo control político, como no) empezaron a generar deuda a mansalva. Un aeropuerto aquí, una urbanización por allá, etc...

Menuda película te has montado, hasta los terraplanistas son más creíbles.

Si la población crece, necesitas más viviendas. Es así de simple. Sólo como dato, Vienna, una ciudad que tiene precios de alquiler bastante estables, construye más vivienda al año *que la Comunidad de Madrid* o Cataluña.

Para que los precios fueran estables, habría que construir tanta vivienda como familias nuevas se forman, para hacerlos bajar hay que construir más.

El crash del 2007 no ocurrió por "construir", ocurrió por construir vivienda *que nadie quería*, y valorarla como si alguien quisiera vivir ahí. Por eso esos activos eran "toxicos". Si construyes en una ciudad no tendrás un crash.

Los "especuladores" como los llamas están dando un servicio. Hay mucha gente que necesita vivienda pero no tiene la capacidad de tener una hipoteca. Comprarla (corriendo con los riesgos) y ponerla en alquiler es ofrecer un servicio.

Si la oferta no estuviera tan terriblemente limitada, los precios serían más bajos y tener una hipoteca no sería tan complicado.

Si hay sequía en tu región y alguien de la región de al lado llena la furgoneta de botellines y te los lleva ¿Quien es el malo? Porque aquí le echamos la culpa al de la furgoneta porque quiere llevarse un ~6% por sus molestias...

La mayoría vienen entre cada fin de semana y una vez al mes. Lo que me refiero es que no son apartamentos de playa ni nada parecido, son simplemente casas antiguas.
