I noticed that is not possible to use rectangular selection for designator in Altium (PCB view). I have to select them by clicking on each of them. And for moving a group of them I can’t use keyboard shortcut. I understand that designator is not a object by itself but is attached to a component […]

# Tag: then

Problem: I’m working on a project that will require a 60V DC (mobile) power source. I’d like to use DeWalt 20V 5Ah batteries to supply this power, 3 in Series x 3 in Parallel (9 total). Part of this project will be making a circuit that can charge all 9 of these at once, without […]

Here is a fragment of a line in file: LN=FINE FOODS & PHARMACEUTICALS NTM, MIC=XAIM, RIC=FF.MI, SG=MA1 I am interested in extracting the value of tag “MIC”, i.e. my desired output is: XAIM The whole line is quite long: 20200403: #379 IT0005215329 {CU=EUR, GTPID=144115188076657542, II=IT0005215329, IS=18814564, LN=FINE FOODS & PHARMACEUTICALS NTM, MIC=XAIM, RIC=FF.MI, SG=MA1, SN=801670, […]

This is a picture of a recurrent neural network (RNN) found on a udemy course (Deep Learning A-Z). The axis at the bottom is “time”. In a time series problem, each yellow row from left to right would represent a sequence of a feature. In this picture, then, there are 6 sequences from 6 different […]

I have built a client using Apache HTTP Async Client library, I have a pool of http/https requests. The problem is that I need to execute https requests using a Certificate and Client private key. I was able to do that but there is only one SSLContext, so, once I load a Certificate+Private key there, […]

This problem comes from Bosch’s Commutative algebra and Algebraic geometry, Exercise 1.5.10. Let R be the ring of all polynomials $f \in \mathbb{Q}[X]$ such that $f(\mathbb{Z}) \subset \mathbb{Z}$. Consider the polynomials $\; f_n (X)= \frac{1}{n!} X(X-1) \cdots (X-n+1) \in \mathbb{Q}[X], n \in \mathbb{N}$, and show : (A) The system $(f_n)_{n \in \mathbb{N}}$ is a $\mathbb{Q}$-vector […]

PROBLEM These exercises appear in “Advanced Mathematical Methods for Scientists and Engineers I – Asymptotic Methods and Perturbation Theory” by Bender and Orszag (page 139). First: Show that if $\,f\sim a(x-x_0)^{-b}\,$ as $\,x\to x_0^{\,+}\,$ then $$ (i)\;\int^x\!f\,dx\sim \frac{a}{1-b}(x-x_0)^{1-b}\qquad \mathrm{as}\;\,x\to x_0^{\,+} $$ if $\,b>1\,$ and the path of integration does not pass through $\,x_0$. Just below, […]

I’m running an IPython notebook through Django’s shell_plus with the following command: sudo ./manage.py shell_plus –notebook I’m not entirel sure how it works, but ./manage.py shell_plus knows to look for additional settings in django’s settings.py file, where I have the following IPython arguments: IPYTHON_ARGUMENTS = [ ‘–ext’, ‘django_extensions.management.notebook_extension’, ‘–profile=mitchell’, ‘–port=8889’, ‘–notebook-dir=/home/rootadmin/server/’, ‘–certfile=/ssl/fullchain.pem’, ‘–keyfile=/ssl/privkey.pem’, ‘–ip=*’, ‘–no-browser’, […]
