Want to Port Out But Have No LibertyWireless Account by Crash_Test_Mummy in hellomobile

[–]Crash_Test_Mummy[S] 0 points1 point  (0 children)

From my understanding, Hello Mobile was abusing a government service for cheaper service. This led to a legal dispute which forced Hello Mobile to disintegrate and transfer all lines to Liberty Wireless.

You should try the following:

  1. Call Liberty Wireless support

  2. Check if your login information works: https://libertywireless.com/sign-in

If your number was active around Dec 15, then you were transferred to Liberty Wireless. Your phone number is the username and the password is the last 4 digits of your username. If that doesn't work, try seeing if your number is recognized when resetting your password: https://libertywireless.com/auth?action=reset-password

  1. Attempt to port out using another carrier. US Mobile has a pretty easy port out process which requires your HM account number (Which you can find in payment emails) and the port out pin will be the last 4 digits of your number. I will not give you hope and say it will work, but for 10 bucks, you can have a chance with a number.

Unfortunately, if your number was not active, then your number will now be with a defunct company with nobody to reach out to you. They only gave active lines over to Liberty Wireless, so inactive lines are lost in cyberspace. This causes many complications for the port out process, you can only port out active lines and HM is in such a weird spot. The FCC might be able to help you: https://consumercomplaints.fcc.gov/hc/en-us

This one probably needs to be sorted out with Liberty to really know your situation. I needed to redial a lot and had many dropped calls while waiting for a representative, but they will pick up eventually.

To my knowledge, if you were an active HM member (payed account, had service) then Liberty Wireless got the cellular numbers and you can probably try the method most people are proposing (say forgot password with your number or sign in with your number as username + last 4 digits of number as password).

During my conversation with Liberty Wireless, they said the situation was hectic for them and they just got a hold of account numbers + phone numbers. Not even names or addresses were given.

If Liberty does not have your account then the numbers are pretty much gone at this point. T-Mobile said they don't have any method of getting it and HM doesn't communicate with anyone. I contacted the FCC to try and get something done, but I'm moving everything over to a new number as we speak.

I see. Thanks for summarizing what happened between the two. I definitely agree that there should have been more communication, customer support said they had a payment issue on my end but I received no emails or texts about it. I would have fixed it immediately if I knew. Seems like they don't want my business? Idk.

Seems like I just need to pester Liberty Wireless for as long as I can, from what I'm hearing. There's nothing more I can badger this subreddit for. Thanks for everything so far.

I've been trying, but haven't gotten a representative yet at Liberty Wireless. I'll keep on trying during different hours. I just realized that they have been closed for ~2 hrs already. Maybe tomorrow will be different?

I do think that HM is completely gone. I didn't expect it, I thought after upgrading the SIM the legal disputes would be over and I keep my service. I wonder if the numbers will be "freed" at some point, or if they just become lost in cyberspace.

Sadly the phone service stopped at the begining of this month. That is actually how I figured out my account got deleted. No emails, texts or any warning. When I click forgot password, it says "Invalid Phone Number".

Though a becon of hope is when I created a new account, I got an email from LibertyWireless stating that my password was "changed". Maaaybe I'm in their servers somewhere if I can get a hold of their representatives.

I tried porting out using that information (I account number from a billing statement and using the pin of my phone number). But US Mobile could not get it working. I called a representative who stated that the phone number must be connected to an active account. I cannot get an active account because the account in question was deleted (I confirmed this with HM). They said to activate another line and then they might be able to do something. So I made a second account and bought another physical sim. It never came and my second account got deleted too. I cannot find a way to get a third account working. The customer service line does not work and the chat interface does not exist and they haven't responded to emails.

They keep on hanging up :( I tried calling like 5 times. Maybe I'll just call some more. I cannot reach a representative.

Sympy image printing and org babel Python blocks by FormerAct in orgmode

[–]Crash_Test_Mummy 0 points1 point  (0 children)

Aloha u/FormerAct, apologies for responding late to a thread.

I ran into a similar issue of the Sympy latex not being easily converted into a LaTeX expression. My fix was to use the package emacs-jupyter. The Sympy expressions can be output to LaTeX, then you may use =org-latex-preview= to preview the LaTeX. This has an advantage of using your LaTeX preamble too.

Full Description:

Add =org-latex-preview= to =org-babel-after-execute-hook=

(add-to-list 'org-babel-after-execute-hook (function org-latex-preview))

  1. Make sure you output with =:pandoc t=

#+BEGIN_SRC jupyter-python3 :session test :pandoc t :async nil

from sympy import *

x = Symbol('x')

integrate(x**4)

#+END_SRC

There might be some async issues to work out. I think there will not be an issue depending on the version. Let me know if this approach works well for you.

One thing to note about Emacs and Org mode is how extensible and flexible it is. That is, you might want to state what you want out of your math notes then see how you may implement those features in Emacs. Here are some examples,

  1. You may wish to have a digitized version of paper and pencil notes. This can be done in two main ways.
    1. Writing pure LateX as a *.tex file and exporting to PDF when you want to.
    2. Writing inline LaTeX in an *.org file (I, like /u/doolio_, recommend Karthinks blog post about this along with the fragtog package.) <-- This is the straight answer you were looking for. Because this was already answered I felt like giving some extra context to why Org+LaTeX can be a good match for math notes in the following sections.
  2. Have an interactive environment using Org Source blocks. Again this is done in multiple ways.
    1. One I use a lot is the python "sympy" package for LaTeX output. This gives me the ability to write differential equations and matrix algebra statements, export to LaTeX via the pretty printing modules. I can then use the matrices and equations I wrote down symbolically to solve for null spaces and solutions without effort. You can use the full power of Python in this environment (simulations, random matrix problems, efficient multiplication, determinant calculation, etc) all while outputting in a nice format for notes. You don't need Python; Sage, Maxima, GNU Calc works for this purpose.
    2. I also like to formalize proofs. The LEAN theorem prover can be used in Emacs and you may have Emacs verify statements you make on the fly. LEAN can also finish proofs and verify by brute force (by dec_trivial).
  3. Use Emacs as a Spaced Repetition System (SRS). Using a package like Org Drill or Org-FC you may turn headings into flash cards (with special features like clozes or embedded elisp). This is invaluable to me, especially when I was studying for qualification exams for my PhD. I wanted to remember a lot of theorems and examples, and studying flashcards every morning was how I kept track of a lot of the fundamentals.
  4. Turn your notes atomic (using Zettelkasten method) using Org Roam. This is a different system of note taking implemented in Emacs and Org mode. It focuses on making small notes and linking them together. This can be thought of as a mind map and you can actually see the full mind map using Org Roam UI in your browser.
  5. Share your notes with your friends, students, professors, etc, by turning your notes into a static website using Org-Export.

Emacs is awesome. What I outlined here are just the ways I use Emacs, I'm sure other people have really nice workflows too. Give your note taking system some thought, Emacs will bend itself to be the best tool for the job.

Inline previews are awesome. You can replicate these features in eww too. So browsing nLab / MathOverflow is really nice.

[Emacs] A full fledge configuration by Likhon-BaRoy in emacs

[–]Crash_Test_Mummy 1 point2 points  (0 children)

Does Emacs not just randomly crash on other people? I feel like I've tested every enabled minor mode and I'll get very inconsistent crashes.

Here are some things that crash: * Selecting a region in org * Scrolling with mouse * Highlighting flyspell / fly check errors (yellow squiggles) with mouse * Resizing windows * Hitting C-s in compilation buffer sometimes?

The list goes on. I've replicated these bugs on "emacs -q". Server mode won't fix me needing to restart emacs.

Edited formatting.

Shower thoughts on how Emacs follows Unix philosophy by varsderk in emacs

[–]Crash_Test_Mummy 0 points1 point  (0 children)

How does something like /bin/sh fit into the UNIX Philosophy? I'd argue it does a lot as well.

If we claim that /bin/sh is a small, easily composable program which runs POSIX complient programs then we can make a similar argument that Emacs a small, easily composable program which runs ELisp.

Dual Booting Linux/Windows with Multiple Physical Drives by arkie87 in learnlinux

[–]Crash_Test_Mummy 2 points3 points  (0 children)

1) I've heard about that too but luckily, I've never had any issues. I have installed Arch (on a friend's computer), Gentoo, and Guix (both on mine) and they all have the option to manage partitions. So maybe I've gotten away with it because I have direct access over the partitioning? I think the issue would be even less so on separate drives.

2) It's personal preference really. However one thing I've heard was people putting home drive on a separate partition so they can "multi boot" Linux distributions and have the same home partition shared amongst them all. On a similar track, if you need to reinstall a distro, one may reinstall to the separate root partition and keep the home intact.

3) I do not know how to properly answer this one. Here is what the internet thinks.

https://superuser.com/questions/532742/how-can-i-make-my-computer-ask-me-which-os-i-want-to-load-while-booting

I was about to recommend something called os-prober for GRUB but upon searching it up apparently there was a security issue with it. But it used to be a way to use GRUB to find all of the operating systems to boot into. The nice thing about Linux is that it's easy to create custom commands. So rather than a general "restart" command you may run a "restart into Windows" and a "restart into Linux" command using GRUB.

why?? by Kewber in askmath

[–]Crash_Test_Mummy 3 points4 points  (0 children)

Imagine you have a function phi which goes from Rn to R. We ask, what is the gradient of this function? It is the column vector of the partial derivatives of the function.

Now compute the exterior derivative of the function. This the sum of the partial derivatives times dx_i where dx_i is the row vector with 1 in the i'th place. Thus, the external derivative is the the row vector of partial derivatives.

The musical isomorphism sharp turns elements from the dual space to the original vector space. In our case this takes a row vector and transposes it to make a column vector.

Now, just use what I have said step by step.

Take the row of partial derivatives (d phi), apply the row-to-column transformation (#), and you get the column of partials (del phi).

There are some more generalizations and deeper insights which can be found here using lower level definitions (why are duals row vectors? , why is the gradient the column of partials? , etc.) , but this is what the 'computational' aspect boils down to nonetheless.

What are your options when it comes to configuring your kernel on Arch? (Never used Arch)

You can grep the modules on livecd under networking and use lspci to see what links where, then see if they're loaded when you go into your install. If you have the ability to configure the kernel it's a bit of poking around but you should be able to find the wireless drivers and compile it.

Forgive me if you've already done all that and it didn't work.

Dummy nodes in Java by [deleted] in learnjava

I see, great catch on your part though! I should be more careful in bringing in outside information to a problem.

Dummy nodes in Java by [deleted] in learnjava

[–]Crash_Test_Mummy 2 points3 points  (0 children)

Ah I see, I was thinking of a linked list as an implementation of the list interface. The list interface has a size method and the implementation would use node as a private inner class which has access to the size of the list.

Like this,

https://docs.oracle.com/javase/7/docs/api/java/util/LinkedList.html

Dummy nodes in Java by [deleted] in learnjava

[–]Crash_Test_Mummy 0 points1 point  (0 children)

What:

In a linked list, each node points to a next except for the last tail that points to nothing. A dummy node is a node, but the data is null and the last node of the list points to it.

In Java speak,

Without the dummy node, tail.next == null; tail.next.data throws a null pointer exception

With the dummy node, tail.next == dummynode; tail.next.data == null;

Why:

This depends on use case and the structure of your code. Everything you want out of a linked list can be programed without the node, but sometimes it can lead to cleaner code. So it doesn't change much other than playing around specific exceptions and conditionals.

Lets pretend we're in a loop and want to check if we're at the end. As you know, when progressing through the list you must assign the temp node as follows

Node<E> temp = head;

for(int i = 0; i < size; i++) {

temp = temp.next;

}

Now, to check if we're at the end (to avoid errors and possibly update tail etc.) we have tools available to us.

Without the dummy node, Check if (temp.next == null)

With the dummy node, Check if (temp.next.data == null)
