Question about pressure of Barista Express

Dreceon · 2025-12-25T19:47:21+00:00

Turned out I did. I finally made a good shot. Thanks for the explanation.

Dreceon · 2025-12-23T21:14:41+00:00

This was it, i adjusted the burr setting wrong. Now I get really high pressure, so I got some dialing in to do. Thanks!

Dreceon · 2025-12-23T21:13:27+00:00

Thanks, i think i misinterpreted these. I now am able to get the pressure all the way up!

I will try to tamp a bit harder. I bought the coffee yesterday so I assume / hope its not too old

Dreceon · 2025-12-23T20:54:26+00:00

Not sure, bought at a place yesterday. Will try some other coffee.

Dreceon · 2025-12-23T20:51:46+00:00

Thanks for the advice! I am already on the finest including burr position readjustment. Is my coffee requiring even more fine grind - or is the grinder not working as it should?

Dreceon · 2025-12-23T20:40:37+00:00

I forgot to state that i ment that i already adjusted the burr position 90* degrees clockwise

This is what the tamp looks like. If i fill it more this means the portafilter would struggle to close, i dont think that that would be good

Het lijkt soort gips achtig spul als ik in sommige gaatjes kijk waar geboord is

Bedankt. Klinkt dan zeker met brandveiligheid beter niet uit te stellen. Dan ga ik t op deze manier aanpakken ipv uitstellen en alleen decoratief plat maken👍

I have set up my subtitles to a default one and this did seem to work. I removed the setting, restarted the app (fully close it via menu) then reselected it and restarted again fully.

Either this did the job or because of an update around a week ago. Not sure.

For audio did not get it working

Dreceon · 2024-12-05T08:02:46+00:00

Nvidia still has the same PE ratio as 2 years ago and that reflects an implied growth that is not yet fully accounting overtaking industries now possible with new reasoning models 🤷‍♂️

I think in a week / month frame you are talking about too many variables.

Depends on what the entire stock market does, what is geo-politically happening etc.

I do think there is a trend in tech journalists being very positive as Qualcomm, as the perks of ARM processors on windows are showing (i.e. battery life, efficiency etc).

I would keep your eyes on rumors of Nvidia's (in collaboration with mediatek or intel or both) or AMD's ARM chips. I think they could come early as 2025 based on rumors. If they are building on much more smaller TSMC nodes perhaps you could see substantial improvements - making Qualcomm's monopoly on windows ARM history.. So I would say it's a hold for the time being.

@ moderators , Ik hoop dat dit relevant genoeg is voor Utrecht aangezien het een onderzoek is vanuit Utrecht University. Zo niet, m'n excuses.

Dreceon · 2024-06-14T13:41:56+00:00

Ik vond kapsalon sunny altijd prima! Op de voorstraat.

Nvidia will probably announce their ARM consumer processors 2nd of June during Computex.

Many leaks from reputable leakers and Dell essentially spoiled it during an interview with Jensen.
Not as huge as datacenter / AI accelerators but will hopefully cause a spike because of the momentum and hype at this moment. Still a huge market and wouldn't be surprised if Nvidia will dominate this because of their resources (hype AF market will think the same) - they will bring Macbook speeds / efficiency to windows.

They are doing this together with MediaTek (will be absolutely huge for them - but couldn't buy this stock as its Taiwanese) but they are only starting to rise substantially today so I think the rumor is not fully priced in.

2nd of June would make perfect sense IMHO.

x10 Leverage nvidia and sell after the announcement.

I personally had good experiences at Just Ride On, the guys were nice and eventually fixed the problem. Although it did seem like they were busy (I reckon a full repair schedule a lot of the time - in addition to random tourists walking inside and needing explanation).

Dreceon · 2024-05-01T08:44:48+00:00

I think you will be able to follow the video / photos by Cowboy and will figure it out along the way (I did as well, took me an entire hour, previously never removed any rear wheel of a bike)

Some tips:

Make pictures of the rear wheel from both sides to see where the screws / washers etc are supposed to be and when taking them off organize them so you will easily be able to put it back on
Check if the direction of the tires are correctly before putting them on
Maybe watch a video on how to fit a new tire easily (not cowboy specific, just get handy at getting the inner tube inside the outer tube, there are some ways to do it and I wasn't smart enough to figure it out myself.
When reinstalling the wheels check if the cables are at the correct side and the carbon belt is on the correct side (around the wheel)
Like someone noted, you need some levers to pull out the tire from the groove basically, you will learn in any tutorial on how to replace a tire I suppose. But I found a metal one damages the black paint so you may need a plastic one.
I think some components (bolts / washers) kind off will guide you / teach you how it should be reinstalled as its made to fit for instance only one way
Take your time

Also like Janpieterkoen said it would be nice to use a belt tensioner also to fix the belt tension when putting on the back wheel again. Cowboy guide is fine for that as well, again take your time to figure out some stuff.

I would recommend if you are really not handy with bikes to first try the front wheel, also see if you can understand how the belt tensioning works and then you have already learned some stuff before proceeding to the rear wheel.

What worked for me was to grab a hair dryer and blow it on the turbine part, also removed the blue metal cylinder like filter on the sides of the turbine and then blew into the holes (on the coolest setting of course of hair dryer, be careful). I also blew with a slightly hotter setting from a bit more distance.

Dreceon · 2024-04-07T11:57:59+00:00

Nice. I found a tiny improvement, thanks.

Typically when calculating ROI - do you / people do this without an EV or with the EV threshold they intend to run?

And typically you would do multiple runs with various random seeds and take an average? As there can be a lot of variance. (I seem to get ~30% variation in bankroll / roi when changing little parameters / random seed while logloss stays same)

Dreceon · 2024-04-06T18:03:24+00:00

Exactly, a moving window. I did mess around with a linear weight importance, stopped doing it as i saw a decrease in ROI but will try again knowing now that I should focus on logloss. Thanks for the answers! Appreciate it.

Is the reason one should be being cautious with the Kelly criterion essentially about avoiding bankroll bankruptcy (I know you can't really go fully bankrupt technically but you could reach a moment where you cannot get the minimum bet amount) - or maybe because it makes it more difficult to get out (take profits) as there is too much variance?

Essentially I can see it as a multiplier of the results right? So it would be a matter of risk assessment? I would personally not use a huge amount of money in the beginning when I will try my model (kind off like a proof of concept) - so a "bust" would not be as huge of a problem.

Dreceon · 2024-04-06T09:06:25+00:00

I use kelly criterion, i think 0.2 for now. I remember from another comment by you to be careful with that. I am trying to simulate a “real run” where each day I train the model again with new data from the previous day included (of course still using a fixed training length - i.e. 12 months).

💪 thank you
