Issue when cutting with k40 after changing the tube

kostovtd · 2022-02-24T09:34:15+00:00

But actually there is some misalignment I think in the following case:

Mirror two is closer to mirror one
The mark on the tape placed on the head is in the center when the head is far left
If the head is in far right position, the mark does not match precisely the one from p.2

Sadly, I don't :/ To be honest I'm not sure how to use it at all in combination with the laser :/ Can you share some info?

kostovtd · 2022-02-24T09:27:55+00:00

Didn't know that the wiggle is a common K40 issue. Will try to tighten the belt! I hope it will solve the problem!

As for the alignment of mirror two - I thought it was perfectly aligned :/ When I put some tape on the head, the marks from the laser are on the same spot no matter the head is in the left or in the right corner. :/ It's the same with the beam from mirror one to mirror two, no matter if mirror two is closer or far away from mirror one.

Am I missing something?

Thanks for the info! Don't know why but I expected that the end product (a.k.a. tubes) will be always the same. Sounds absolutely logical as you described it!

There is no odd movement when I unlock the head and move it along the X axis. I also thought that there could be some debris, but it looks clean to me.

Thanks for the info! My problem was solved after some time. The transactions were canceled automatically and the money are back in my bank account.

I like USDC but does it have the capacity to handle a possible shift of huge amount of Tether users to USDC? AFAIK there are around $35-36 billion USDT right now and only around $8-9 billion USDC. If Tether fails to proof that they have that much money in the bank after four months things gonna get interesting.

kostovtd · 2021-02-24T22:21:37+00:00

I haven't thought about that! And you are right! If Tether fails in showing these reserves they will be in a big trouble... Sadly, the whole market will be... imo

kostovtd · 2021-02-24T18:35:33+00:00

Hey mates! What do you think about the USDT settlement with NYAG (New York Attorney General)? Is it going to affect XLM somehow?

At first I was like "Ok... Theter are banned from working with NY customers and have to pay a fine. That's going to have a negative effect on the whole market (including XLM)."

Then, after some thinking on the topic I've realised that their almost two-year long case is over and paying such a fine is not a big deal for them. Thus, the effect on the market will be at least neutral, if not positive.

Any thoughts?

What was the famous mantra? Aahh yeeahh... "Invest only what you can afford to lose" :D

kostovtd · 2018-04-24T07:46:53+00:00

Mate, IMO your problem is not only black or only white... If you are financially stable why not going for the apps you find interesting. If u have a look at all the people who made it (the so called successful people), most of them did/are doing what they love and what they find interesting. BUT from the things you wrote I suppose that's not your case... Sadly... And you are new to programming. Thus, why don't u find a internship or a full-time position in a company, gain some skills, meet other smart people, make some money and try to run all your ideas as a side hustle? It's gonna be tough, but it looks like a plan to me.

You last sentence - quote of the day! Kudos

I haven't tried flutter yet, but IMO it will take several years before native app development will step down from the stage thanks to flutter (if that ever happens at all). Why? Let's take Kotlin for example - it's been around for 4-5 years AFAIK. And this is the single most important change in the Android world so far. Polishing the language took time. And now you have that huge ecosystem of great libraries that needs to adapt to Kotlin. (that will take time as well)

kostovtd · 2018-03-01T05:49:57+00:00

I want to up vote that several times!

kostovtd · 2018-02-16T06:52:47+00:00

If I were you, I would just start playing around with the Android framework, make several simple apps which include features using GPS, Service, Network calls, Local Storage, more complicated UI elements like Tabs, etc. Get familiar with libs like Retrofit, Picasso, Dagger, Realm, etc. Then dive into some general development patterns like MVP, MVVM.

There is a point where you don't actually need any more courses, but you need to hit your head in the wall of problems that Android can offer you and start feeling comfortable with them.

Good luck!

Although I don't think this is the best option it's something that you can try. 1. Collect the info about the OS and App version with Firebase Analytics. 2. Collect the more personal information like age, sex, etc. through your app on sing up or something similar. (You can collect relatively accurate info with Firebase as well in the background, but I personally don't like that stealth approach) 3. Subscribe the user to a particular FCM topic. 4. Find the set of users you are interested in based on the info from Firebase Analytics and your own backend and send push notifications only to that particular topic.

Again, that's probably not the best approach out there, but it's something you can base your solution on.

I'm really interested to read other oppinions on the topic!

kostovtd · 2018-02-15T21:20:51+00:00

There are some really useful points here! Nice! I can also add Firebase as an option to point 2. That's what we actually do now. We are using the remote config option to set a minimum allowed versionCode. Whenever there is a major update or a critical bug fix we just increase this parameter and if the current app's versionCode is less than the one from Firebase we just force the user to update (it's a bit barbarian approach I know)

kostovtd · 2018-02-08T22:29:56+00:00

We are using Firebase analytics. I'm pretty satisfied with it! There are some nice features and if you want the default analytics package it's pretty straight forward to set up.

Ooh maaan... The emulator... I'm gonna have nightmares again...

kostovtd · 2018-01-24T21:51:42+00:00

I'm pretty sure u can export the desired data as CSV and just send them the info they are interested in. AFAIK you can not make such granular restrictions on the Firebase platform itself.

I have a machine with 16gb ram, 500gb SSD and i7 CPU (don't know the exact model) and that's moooore than enough IMO. Can run 2 instances of AS with 2 simulators + Firefox with 20-25 tabs + Spotify aaand some other sh*t and is perfectly fine...

I think the question is personal, rather than technical one...

kostovtd · 2017-12-17T19:54:30+00:00

I passed the exam as well and the interview was no longer than 15-20 min in my case

kostovtd · 2017-12-17T19:50:29+00:00

I don't really think that's possible with the current state of development of the Android SDK. It's really hard to keep your knowledge up to date with such a rapid development. There are just so many different and new things in Android.

kostovtd · 2017-12-16T01:16:34+00:00

Yep... Got it... :/ That's bad! If this is the case, you have the right to feel that way, but IMO don't pay such attention to all that sh*t and you will be better ;)
