How to set CSS attributes to default values for a specific element (or prevent inheritance). <p>Given any HTML element that is a child of another element and is automatically inheriting a series of CSS attributes: how can you set one (or all) of those attributes to the default value?</p>
<p>Example:</p>
<p>CSS:</p>
<pre><code>.navigation input {
padding: 0;
margin: 0 30em;
}
</code></pre>
<p>HTML</p>
<pre><code><div class="navigation">
Some text: <input type="text" name="one" />
More text: <input type="text" name="two" />
<!-- The next input, I want it to be as browser-default -->
<div class="child">
<input type="text" name="three">
</div>
</div>
</code></pre>
<p>Here, by <strong>browser-default</strong> I mean I want it to look exactly as if no CSS at all was applied to that element.</p>
<p>Here I'm using an <code>input</code> element as an example, but I'm talking about any kind of element. I'm not asking how to set different CSS attributes to that specific element, I'm asking how to <strong>reset</strong> it to its defaults.</p>
<p>Different elements have different default attributes like <code>padding</code> when they are not set. For example, a <code>button</code> that has a padding of <code>0</code> in CSS will wrap its text without any space. You can later set its padding to another value, but how would you set it to the default padding?</p>
<p>Thanks in advance for any comments!</p>

Has anyone tried the TinyScreen OLEDs?. As the title says, has anyone played around with [these](https://tinycircuits.com/products/tinyscreen) at all?
I have a lot of experience with the pi, but none with an arduino. These are TINY arduino based screens (and other devices) that seem to be self contained arduino systems. I have a pair of "VR" HUD glasses ([Virtual IO iGlasses](http://www.amigahistory.plus.com/virtualio.html)) from the 90s that don't work. Gutted them down to just the screens and driver board, and added a pi zero. Got video working and the display is.. Well.. Disappointing.
They came with dual 0.7" lcd screens and I'm looking for alternatives to upgrade. These may just complicate things since they are individual self contained arduinos, but they are i2c and they offer two addresses for the ability to use two simultaneously. | 0non-cybersec

Why isn't it possible to name a folder "._." in Windows 7?. <p>I just noticed that it is not possible to name a folder <code>._.</code> - it gets named <code>._</code> instead. Sometimes, it disappears just after naming it but reappears after refreshing the view. Windows seems to have a problem with dots at the end of a filename - why is this?</p>

OpenVPN client site network routing. <p>I have the following openvpn setup, the goal is to make host D can connect to any of the computer(linux) in the corporate network to do some maintaining job: </p>
<pre><code> corporate network remote vpn server
============================================= =====================
A B C(vpn client) D(vpn server)
10.0.10.101 ---- 10.0.10.100 |
10.0.51.100 ---- 10.0.51.101 |
10.8.1.2 ---|-- 10.8.1.1
|
</code></pre>
<p>host B route table:</p>
<pre><code>10.8.1.0/24 via 10.0.51.101
</code></pre>
<p>host C route table:</p>
<pre><code>10.0.10.0/24 via 10.0.51.100

<p>host D route table:</p>
<pre><code>10.0.10.0/24 via 10.8.1.2
10.0.51.0/24 via 10.8.1.2
</code></pre>
<p>The openvpn is being setup with subnet topology, which links corporate network subnet 10.0.51.0/24. </p>
<p>My purpose is to make host D can link with host A, here is the progress I made:</p>
<ol>
<li>B ping through D(10.8.1.1): OK</li>
<li>D ping through B(10.0.10.100): Failed</li>
<li>D ping through B(10.0.51.100): OK</li>
<li>B ping C 10.0.51.101/10.8.1.2: OK</li>
<li>C ping B(10.0.10.100/10.0.51.100): OK</li>
</ol>
<p>It seems that route 10.0.10./24 via 10.8.1.2 being ignored when doing traceroute. How can I setup to make the host D on subnet 10.0.51.0/24 link to 10.0.10.0/24?</p>

I caught my girlfriend (29F) texting another guy in a flirty way. How should I (29M) react?. To set the stage, I’ve been dating my girlfriend seriously for about a year now, total for about 2 years, and we are at the stage of talking about moving in together.
Yesterday, I was using my girlfriend’s computer for a minute to search something on Google and saw that her WhatsApp popped up. A guy texted her that I didn’t know. I saw that they had sent pornhub links to each other as “a joke”. Curious, I decided to read through their prior text messages (I’m not proud of this). There was a history of them texting for a long time, mostly innocuous stuff, talking about skiing or sending memes to each other, but definitely with a flirty vibe. I then read him talking about them having a threesome together, and she had responded that that was “her dream”.
After reading this, I was in shock and confronted her immediately - I was already at her house in quarantine. I talked through it with her and told her I didn’t know what to make of this, does she have feelings for this guy, or if there’s something I’m doing that isn’t fulfilling her needs. She claimed that this guy was her friend for a few years, they had a lot in common and she just saw him as a friend only. She said her texts were meant just to be fun, and it’s just her style of communicating.
Since yesterday, she’s been really remorseful about the whole episode. She read through the texts again and agreed they crossed the line and apologized. She told me that she had texted her friend and let him know that their messages had caused a big fight between herself and me and it’s better they don’t talk anymore.
Overall, I’m really hurt about what happened. If this had happened early on in our relationship, I would be more understanding, but we are serious now so this has hurt more. I want to believe that she was just “joking” and he’s just a friend, but the fact that she never has mentioned him to me makes me feel doubtful about this. She’s 29, an adult and knows what she’s doing at this point. It does make me feel better that she texted this guy after the event (assuming she’s truthful) and set boundaries with him.
I’m back at my place, and I haven’t made any decisions either way yet. I’m not sure if I’m making this too big a deal, or not enough of a big deal. I don’t know if I should I (1) make a boundaries chat or (2) do more serious things, like require her to let me read through her phone, or maybe even leave her entirely.
Would love advice here, thanks! Let me know if I can provide any clarification.
ONE WEEK LATER UPDATE:
Thank you all SO MUCH for the advice! The comments here really helped me think through this all.
After much thought, I ended up telling her that I lost my trust of her, and I didn’t believe her story of it being a little mistake, but was willing to give it one more shot anyways. She needs to work to rebuild my trust of her. She responded to all of this quietly and accepting, which I think given the circumstances is understandable. We are going to take it day by day, but I’m hopeful that we can rebuild trust together.
New question for you all: to close the loop, I asked my girlfriend to message the guy she’s been talking to and set boundaries, which she said she did. However, do you think it’s fair of me to ask to see those messages? Because I’ve lost trust of her, I have this thought in the back of my mind of what if she didn’t actually message him? Should I take her word for it, or ask for proof? | 0non-cybersec

Is there something about drinking cold water that is physiologically more hydrating as opposed to drinking lukewarm or hot water?. I have noticed after finishing running when I drink ice cold water I feel more hydrated than when I drink lukewarm water. Is it more of a mentality with the colder water or does the temperature difference help the body cooler faster? | 0non-cybersec

How to use spot instance with amazon elastic beanstalk?. <p>I have one infra that use amazon elastic beanstalk to deploy my application.
I need to scale my app adding some spot instances that EB do not support.</p>
<p>So I create a second autoscaling from a launch configuration with spot instances.
The autoscaling use the same load balancer created by beanstalk.</p>
<p>To up instances with the last version of my app, I copy the user data from the original launch configuration (created with beanstalk) to the launch configuration with spot instances (created by me).</p>
<p>This work fine, but:</p>
<ol>
<li><p>how to update spot instances that have come up from the second autoscaling when the beanstalk update instances managed by him with a new version of the app?</p>
</li>
<li><p>is there another way so easy as, and elegant, to use spot instances and enjoy the benefits of beanstalk?</p>
</li>
</ol>
<p><strong>UPDATE</strong></p>
<p>Elastic Beanstalk add support to spot instance since 2019... see:

Multiple DatePickers in same activity. <p>I am absolutely new to the Android platform and have been building an application while learning the development process.</p>
<p>Currently, I am working on an activity in which i need to deploy 2 date pickers. One is a "Start Date" and the other is an "End date". I have been following the DatePicker tutorial on the android developers page here: <a href="http://developer.android.com/resources/tutorials/views/hello-datepicker.html" rel="noreferrer">http://developer.android.com/resources/tutorials/views/hello-datepicker.html</a></p>
<p>For one DatePicker, it works just fine.</p>
<p>Now my problem is, when I replicate the whole process for a second date picker, it shows up just fine on the emulator as well as on the handset. But when no matter which button I press to select the dates, only the first TextView is updated and the second TextView keeps showing the current date.</p>
<p>Here is the code:</p>
<pre><code>package com.datepicker;

Is there a Serre Tor formula for nonproper intersections?. <p>Background: Let $X$ be a smooth complex projective algebraic variety, and let $V$ and $W$ be closed subvarieties. For simplicity, let's assume that $\dim V+\dim W=\dim X$.</p>
<p>Now Serre's famous Tor formula says that if $V\cap W$ has dimension zero, we have:</p>
<p>$$V\cdot W=\sum_{Z\subset V\cap W}\sum_{i=0}^\infty(-1)^i\operatorname{length}_{\mathcal O_{X,z}}\operatorname{Tor}_{\mathcal O_{X,z}}^i(\mathcal O_{X,z}/I_V,\mathcal O_{X,z}/I_W)$$</p>
<p>where the sum is over the irreducible components of $V\cap W$ (in this case, a finite number of points).</p>
<p>However (according to Wikipedia <a href="http://en.wikipedia.org/wiki/Intersection_theory_%28mathematics%29">here</a>), if $Z$ is an irreducible component of $V\cap W$ with positive dimension (this is called a nonproper intersection), then the alternating sum of $\operatorname{Tor}$'s, which I'll call $\mu(Z;V,W)$, is zero. Unfortunately, this means it cannot be used in exactly the same way as before to calculate $V\cdot W$. For example, if $V=W$, then the answer would always be zero, though certainly there exist half-dimensional varieties $V$ with $V\cdot V\ne 0$ (in fact it can even be negative).</p>
<p>Is it possible to remedy this situation? How does one count the intersection multiplicity if the intersection is not proper?</p>
<p>Comment: I know how to compute the self-intersection $V\cdot V$ as the top chern class of the normal bundle evaluated on $[V]$. I'm looking here for an answer that's the most general, i.e. applies to all $V$ and $W$ of complementary dimension, regardless of the dimension of their intersection.</p>

How to use spot instance with amazon elastic beanstalk?. <p>I have one infra that use amazon elastic beanstalk to deploy my application.

Injectivity of the cohomology map associated to the pullback of line bundles. <p>Let <span class="math-container">$f:X\to Y$</span> be a flat, surjective, smooth morphism between smooth algebraic varieties (over <span class="math-container">$\mathbb C$</span>). We assume that <span class="math-container">$f$</span> has relative dimension <span class="math-container">$n$</span> and we assume also that <span class="math-container">$\dim Y\ge 2$</span> (just to avoid the case of a curve that might be easier).</p>
<p>Let <span class="math-container">$L$</span> be a line bundle on <span class="math-container">$Y$</span>, then we have a homomorphism in sheaf cohomology:</p>
<p><span class="math-container">$$H^p(Y,L)\to H^p(X, f^\ast L) \quad\text{for } p=0,1,\ldots,\dim Y $$</span></p>
<p>Can we say anything about the injectivity of this map? Do we need some additional condition on <span class="math-container">$f$</span>?</p>

Customize flask form as table. <p>I've been biting my nails on this one for quite some time. In my Flask-app I currently have a product-database, for which in the app I have a page that queries each product column into a table. </p>
<p>For example I'd have product <code>1234</code> for which I could view the details (i.e. database columns) in <code>example.com/items/1234</code> which would give me the following: </p>
<pre><code><div class="container">
<div class="content">
<a href="/item">Back</a>
<table class="table">
<thead>
<tr>
<th>#</th>
<th>Value</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">Detail-1<th>
<td>Example</td>
</tr>
<tr>
<th scope="row">Detail-2</th>
<td>Example</td>
</tr>
</code></pre>
<p>What I'm struggling with is the following: </p>
<p>I'd like to be able to add new products with same table-style. For this I have created a form like the following:</p>
<pre><code>class NewArticleForm(FlaskForm):
detail_1 = StringField("Detail-1")
detail_2 = IntegerField("Detail-2")
...
submit = SubmitField("Submit")
</code></pre>
<p>I am now at a total loss on how to customize the form appearance in the template beyond just <code>{{ wtf.quick_form(form) }}</code>. What I tried is the following: </p>
<pre><code><form method="POST">
<table class="table">
{% for name in form %}
<tr>
<th scope="row">{{ name.label }}</th>
<td>{{ name }}</td>
</tr>
{% endfor %}
</table>
</form>
</code></pre>
<p>The table looks good (at least that) but the request is not being sent correctly I presume. The page loads correctly with <code>"POST /url HTTP/1.1"</code> but it doesn't seem to come through correctly. </p>
<p>What I mean by that is that though the request is being sent correctly, as I can see if I run the app via the Flask server. However it seems that nothing is transmitted to the database. The page simply reloads with the entered data still in the fields and nothing transmitted to the database. If I simply use the <code>wtf.quick_form</code> then the data is correctly sent to the database. </p>
<p>So how can I correctly customize the form appearance and/or crucial step did I miss?</p>

New USB headset has buzzing/ringing background noise. <p>I bought the Sentey Symph USB headset on Amazon, which just arrived today and has been having trouble right out of the box. I don't believe the problem is the headset itself, because it has amazing audio and microphone (which only sounds good when listening to itself via headset software).</p>
<p>When I'm playing games or listening to music and other stuff it's fine, but when I'm just browsing the internet or something that doesn't involve sound is when the problem occurs. There is a few things that I can hear. There is a low pitch buzzing sound that can be heard all the time, and then there is this sound that changes in pitch randomly, goes up and down every few seconds which is also always audible.</p>
<p>I think the cause is USB interference because when I move my mouse or use the scroll wheel I can hear slight feedback in the headphones. When I listen to the microphone by redirecting the sound to the headset it sounds amazing, but when it actually gets to the computer it sounds horrible with crackling and static in the background. I can't skype with people because it's so bad.</p>
<p>I'm just trying to figure out what to do to fix it because I want to use the amazing headphones without the interference. I already tried a few things I found on the internet:</p>
<ul>
<li>Moving my PSU cord into the wall instead of the power strip</li>
<li>Taking out the mouse to see if it's only that</li>
<li>Moving the headset to different slots in the front and back</li>
<li>Putting it in a USB hub instead of the computer</li>
</ul>
<p>But nothing just seems to be working.</p>
<p>EDIT: even when the audio is muted on windows, I still hear strange noises that almost sound like radio waves as described above. I'm not sure if it's the DAC because even when the sound is disabled it's still getting interference.</p>

Storing app / site settings within mongodb using mongoose. <p>I have been developing a node.js based site which is already running successfully live and it uses mongodb as the backend storage using the mongoose.</p>
<p>The thing is that, I want to implement some configurable settings for site (which should be able to configured using the /backend/ page).</p>
<p>So I've to find out a way to store all those settings using the mongoose but I couldn't came with a schema that can fit the thing.</p>
<pre><code>var mongoose = require('mongoose');
var SettingsSchema = new mongoose.Schema({
});
mongoose.model('Settimgs', SettingsSchema);
</code></pre>
<p>Is there anyway that I can force a schema to have only a single document? So I can use the above schema with only one document and put all my required settings there.</p>
<p>Other than I've came with another idea where settings-schema collection will host multiple documents each with their unique section name as the following, but then the contents of the schema for each section should be different. One idea I came with is just storing section specific json as an object data without giving the model details;</p>
<pre><code>var mongoose = require('mongoose');
var SettingsSchema = new mongoose.Schema({
name: { type: String, lowercase: true, trim: true, unique: true, required: true }, // the settings section name
...
JSON-Object or JSON-string here?
Is {data: Object} a possible usage?
});
mongoose.model('Settimgs', SettingsSchema);
</code></pre>
<p>But if I can find a way to define models for sections, it'll be lot better & testable -- like a model for backend-settings and another for front-end settings which should be all stored in Settings collection somehow.</p>
<p>So what I'd like to have is;</p>
<pre><code>var BackendSchema = new mongoose.Schema({
.. backend related settings here..
});
var FrontendSchema = new mongoose.Schema({
.. frontend related settings here..
});
</code></pre>
<p>and finally have a master settings-schema to cover these together and save all those documents to a single collection.</p>
<p>I've searched for a while to see if any interesting reads are available on the topic but had no luck -- will be nice if you can post in case that you are aware of one.</p>

Create RDP gateway in Raspberry Pi or Ubuntu. <p>I have a few systems in my local network and want to RDP them from the Internet. One method is to allocate different ports to each system for RDP and configure them in the router. However, what I need is to configure RDP in default mode.</p>
<p>For example <code><ip-address>:3389/ubuntu</code> should point to <code>192.168.1.102:3389</code>.<br>
Similarly, <code><ip-address>:3389/win7</code> shall point to <code>192.168.1.101:3389</code> and so on.</p>
<p>I searched Google but articles are related to Windows Server, where they prefer making an RDP gateway server. I a prefer a Linux system (and even better Raspberry Pi) to do this task for me. I tried some RDP related searches on Pi and got information on dnsmasq. But I guess its related to connect to outer network (websites) from local network instead of local network from outside network.</p>
<p>Is is possible? Any hint or link/reference will be very helpful.</p>

Can a CSV contain malicious code?. <p>I am working with a system that allows users to upload CSV files, that are downloaded by other users.</p>
<p>The system validates (amongst other things) that all CSV files can be parsed by an RFC 4180 compliant parser, and are valid UTF-8. It ensures that when files are downloaded, they have <code>Content-Type: text/csv; charset=utf-8</code>, and <code>Content-Disposition: attachment; filename="download.csv"</code>.</p>
<p>A concern has been raised that the system could be used to transmit malware or malicious code.</p>
<p>Are there any known mechanisms where a malicious CSV file could cause code to be executed by the recipient? If so, is there any further validation that would reduce the risk posed?</p>

Unbalanced shoulders. Long time lurker, trying to get into BWF. Quick question here, I just realized this morning that my shoulders are kinda unbalanced like so: http://imgur.com/GwQQMSG
I had a childhood injury somewhere between the ages of 6-8 where I dislocated my left shoulder (right in the picture), and I'm not sure if that caused the bulge there.
I'm pretty keen to start out with the RR, my rings (coz I don't have a proper place for a bar) are coming in the mail today!
Will this prevent me from getting any exercises done? Do I need to pay extra attention to any movements to help balance out my shoulders/not injure myself? Any tips for a beginner?

ln() and product confuse me. <p>I have this function:</p>

<p>And I have to compute this: $L(\mu) = \ln\left( \prod\limits_{n=1}^{N} p(x_n;\mu)\right)$ which should be equal to:</p>
<p>$-\frac{N}{2}\, \ln( \space (2\pi)^l|\Sigma|\space) \space- \space \frac{1}{2} \space \sum\limits_{n=1}^{N}(x_n-\mu)^T\Sigma^{-1}(x_n-\mu)$</p>
<p>Note: $\Sigma$ is a covariance matrix.</p>
<hr>
<p>From my attempt I have:</p>
<p>$\frac{1}{(2\pi)^{\frac{l}{2}}|\Sigma|^{\frac{1}{2}}} = \ln1 - \ln((2\pi)^{l/2}|\Sigma|^{1/2}) = - \ln((2\pi)^{l/2}|\Sigma|^{1/2}) = -\frac{L}{2}\ln2\pi - \frac{1}{2}\ln|\Sigma|$</p>
<p>and:</p>
<p>$\ln(\exp(-\frac{1}{2}(x_n-\mu)^T\Sigma^{-1}(x_n-\mu))) = -\frac{1}{2}(x_n-\mu)^T\Sigma^{-1}(x_n-\mu)$</p>
<p>but when I put everything together with the product, it doesn't work out, squares appear and it doesn't feel right...Can you help me please <em>understand</em>?</p>

This Is my first pc build, the pc turns on yet when connected to the monitor it swap from "no cable connected" to "HDMI no signal". I have already tried fixing it by disabling the graphics card and plugging the hdmi cable into the motherboard yet it still didnt work.
Any suggestions before I have to rebuild? Anyone have the same problem?

ffmpeg entropy/bitplanenoise/freezedetect filters correct usage. <p>I am writing a node js package aimed at testing video streams.</p>
<p>I want to implement such features as measuring entropy, bit plane noise and freeze detect wrapping the corresponding ffmpeg filters.</p>
<p>Currently i am having problems doing this (which i assume is the problem of incorrect syntax use):</p>
<ol>
<li><p>Seems my current version of ffmpeg (4.1.3) does not support freeze detect filter:</p>

How to use spot instance with amazon elastic beanstalk?. <p>I have one infra that use amazon elastic beanstalk to deploy my application.
I need to scale my app adding some spot instances that EB do not support.</p>
<p>So I create a second autoscaling from a launch configuration with spot instances.
The autoscaling use the same load balancer created by beanstalk.</p>
<p>To up instances with the last version of my app, I copy the user data from the original launch configuration (created with beanstalk) to the launch configuration with spot instances (created by me).</p>
<p>This work fine, but:</p>
<ol>
<li><p>how to update spot instances that have come up from the second autoscaling when the beanstalk update instances managed by him with a new version of the app?</p>
</li>
<li><p>is there another way so easy as, and elegant, to use spot instances and enjoy the benefits of beanstalk?</p>
</li>
</ol>
<p><strong>UPDATE</strong></p>
<p>Elastic Beanstalk add support to spot instance since 2019... see:

Configure VPS to access SSH with subdomain. <p>Well, I just bought a unmanaged VPS with DirectSpace to try the service out.
I'm currently able to access it through the two IP adresses that they gave me, but now I'd like to get access to it through my Domain, which I get with GoDaddy through GoogleApps.</p>
<p>I'd like to be able to do something like</p>
<pre><code>ssh [email protected]
</code></pre>
<p>and get access to the shell this way.
Also, since I'm using the GoDaddy Name Servers and they are working good enough, I wouldn't like reassign them to my own host (ns1.mydomain.com, ns2.mydomain.com).</p>
<p>I've read somewhere that it is posible by setting an A Record, but honestly I'm lost.
Finally, I'd like to be able to use the VPS for hosting my own Web Site and also some other Customer Sites (with its own domains), so please, let me know if somebody can give me a clue on this.</p>
<p>Regards.</p>

Command re-assigned. <p>I found a Bash script snippet earlier with which to echo a string to stderr:</p>
<pre><code>echoerr() { echo "$@" 1>&2; }
echoerr hello world
</code></pre>
<p>This remained in my clipboard, and when I wanted to edit a file (with VIM) I accidentally pasted this snippet again instead of the file name:</p>
<pre><code>vim echoerr() { echo "$@" 1>&2; }
echoerr hello world
</code></pre>
<p>It seems to have re-assigned <code>echoerr</code> to <code>vim</code>:</p>
<pre><code>$ where vim
vim () {
echo "$@" 1>&2;
}
/usr/bin/vim
</code></pre>
<p>Also, attempting to open a file with VIM now just echos the file name back:</p>
<pre><code>vim path/to/some-file
</code></pre>
<p>Prints:</p>
<pre><code>path/to/some-file
</code></pre>

SSH "sleeping" for a long time before connect?. <blockquote>

<p>I have a very strange issue with my SSH server. Whenever I attempt to connect, it literally waits about 30 seconds to a minute before allowing the connection. Other servers in the same datacenter are connecting in about 2-3 seconds, while this one waits just about the same amount of time before letting any connections through. Is there a configuration option which I can use to tweak this delay time? It's running OpenSSH 4.3p2, OpenSSL 0.9.8e-fips-rhel5.</p>

Why is the product of all units of a finite field equal to $-1$?. <p>Suppose $F=\{0,a_1,\dots,a_{q-1}\}$ is a finite field with $q=p^n$ elements. I'm curious, why is the product of all elements of $F^\ast$ equal to $-1$? I know that $F^\ast$ is cyclic, say generated by $a$. Then the product in question can be written as
$$
a_1\cdots a_{q-1}=1\cdot a\cdot a^2\cdots a^{q-2}=a^{(q-2)(q-1)/2}.
$$
However, I'm having trouble jumping from that product to $-1$. What is the key observation to make here? Thanks!</p>

WHAT operations become slow when git repos become large, and WHY?. <p>This question was asked in various forms on SO and elsewhere, but no answer I was able to find has satisfied me, because none list the problematic/non problematic actions/commands, and none give a through explanation of the technical reason for the speed hit.</p>
<p>For instance:</p>
<ul>
<li><a href="https://stackoverflow.com/questions/29393447/why-cant-git-handle-large-files-and-large-repos">Why can't Git handle large files and large repos</a></li>
<li><a href="https://stackoverflow.com/questions/17543379/why-git-operations-becomes-slow-when-repo-gets-bigger">Why git operations becomes slow when repo gets bigger</a></li>
<li><a href="https://stackoverflow.com/questions/3313908/git-is-really-slow-for-100-000-objects-any-fixes">Git is really slow for 100,000 objects. Any fixes?</a></li>
</ul>
<p><strong>So, I am forced to ask again:</strong></p>
<ol>
<li>Of the basic git actions (commit, push, pull, add, fetch, branch, merge, checkout), which actions become slower when repos become larger (NOTICE: repos, not files for this question)</li>
</ol>
<p>And,</p>
<ol start="2">
<li>Why each action depends on repo size (or doesn't)?</li>
</ol>
<p><strong>I don't care right now about how to fix that</strong>.
I only care about which actions' performance gets hit, and the reasoning according to current git architecture.</p>
<hr>
<p>Edit for clarification:</p>
<p>It is obvious that <code>git clone</code> for instance, would be o(n) the size of the repo.</p>
<p>However it is not clear to me that <code>git pull</code> would be the same, because it is theoretically possible to only look at differences.</p>
<p>Git does some non trivial stuff behind the scenes, and I am not sure when and which.</p>
<hr>
<p>Edit2:</p>
<p>I found <a href="https://docs.microsoft.com/en-us/azure/devops/repos/git/manage-large-files?view=azure-devops" rel="noreferrer">this</a> article, stating</p>
<blockquote>
<p>If you have large, undiffable files in your repo such as binaries, you
will keep a full copy of that file in your repo every time you commit
a change to the file. If many versions of these files exist in your
repo, <strong>they will dramatically increase the time to checkout, branch,</strong>
<strong>fetch, and clone</strong> your code.</p>
</blockquote>
<p>I don't see why branching should take more than O(1) time, and I am also not sure the list is full. (for example, what about pulling?)</p>

What happens when a project switches to a different license?. <p>I've been reading a bit about software licenses, and I'm having trouble getting my head around the idea of what happens when one wants to change the license. I've read a <a href="https://softwareengineering.stackexchange.com/questions/55326/can-you-change-a-license-once-you-pick-one">couple</a> of <a href="https://softwareengineering.stackexchange.com/questions/26548/what-is-the-default-software-license">questions</a> here on the topic and it clarifies things some, but there are still a couple of areas that are unclear to me.</p>
<p>One example: Suppose I have a project hosted on github with no license specified. If someone contributes a patch to my code base and I merge it in, does that patch still belong to them? If so, would I need their permission to change the license on my project?</p>
<p>Another example: Suppose I have my software under some permissive open source license. I understand that I am allowed to change the license on my software at will (barring conflicts with contributors), but does that effect existing copies of the software out there? If I decide to close source my project, do existing copies of the source with packaged OS license remain open source and distributable according to the previous license?</p>
<p>I like the idea of working together with others on projects in a flexible manner, and unless a project actually starts to pick up it seems like unnecessary overhead to go about deciding on an appropriate license. It would be nice to be more aware of the potential conflicts that could crop up, though.</p>

Diagonalisation of a Quadratic form problem. <p>We have a quadratic form (in physics it is called a Lagrangian)</p>
<p>$$L=\frac{1}{2}\sum_{i,j}m_{ij}\dot{x}_i\dot{x}_j-\frac{1}{2}\sum_{i,j}k_{ij}x_ix_j=\frac{1}{2}\big(\dot{\vec{x}}|M\dot{\vec{x}}\big)-\frac{1}{2}\big(\vec{x}|K\vec{x}\big)$$</p>
<p>where $M$ and $K$ are positive definite symmetric matrices. We wish to find a change of basis such that both matrices $M$ and $K$ are diagonal (because then the equations of motion are separated, which is important in physics)</p>
<p>We can diagonalise $M$ with and orthogonal matrix $U$ because $M$ is real and symmetries, so:</p>
<p>$$M=S^TD_MS$$</p>
<p>now since $M$ positive definite it has positive eigenvalues so there exist a matrix $S_{ij}=\frac{\delta_{ij}}{\sqrt{\mu_i}}$ (where $\mu_i$ are eigenvalues of the matrix $D_M$)</p>
<p>we can see that the matrix $US$ transform the matrix $M$ in to an unit matrix</p>
<p>$$(US)^TM(US)=I$$</p>
<p>The matrix $(US)^TK(US)$ is still symmetric because</p>
<p>$$k'_{ij}=\sum_{k,l}(US)_{ik}^Tk_{kl}(US)_{lj}=\sum_{k,l}(US)_{ki}k_{kl}(US)_{jl}^T=\sum_{k,l}(US)_{jl}^Tk_{lk}(US)_{ki}=k'_{ji}$$</p>
<p>and since $K'$ is symmetric there exist a orthogonal matrix $V$ such that
$V^TK'V=(USV)^TK(USV)$
and since $(US)^TM(US)=I$ then changing the basis of a unitary matrix does nothing, that is $V^T(US)^TM(US)V=V^TIV=V^TV=I$.
This proves that the matrix $(USV)$ diagonalises $M$ and $K$ simultaneously.</p>
<p>my problem is the following:
first there is a change of basis that diagonalises $M$ so we rewrite it in a new basis and it is $D_M$ this part is standard diagonalisation, but now we ''shorten'' or ''lengthen'' each eigenvector so that our matrix becomes the unit matrix $I$. I am really confused about this part, this means that every diagonalisable (and positive definite) matrix is a unitary matrix in some coordinatisation, but since $I$ in unchanged by the change of basis any further transformation will leave it unchanged so that means any other coordinatisation also diagonalises $M$ which is the thing we use to prove that the transformation $V^TKV$ that diagonalises $K$ will not un-diagonalise $M$ (that is $(US)^TM(US)$ ) </p>
<p>this would mean that all vectors are eigenvectors of $M$ since any transformation that changes it's basis ($V^TV$) after we have reduced it to $I$ will not change it</p>
<p>This is obviously wrong, but I don't understand what is wrong with it.</p>
<p>and the second and third part of the question is</p>
<p>Are the eigenvector of $M$ and $K$ the same vectors or does just the transformation $USV$ change them, but not to the same basis (but I don't see how it would be possible) </p>
<p>and finally is the new basis orthogonal? (it seems to me it should be based on the principal axis theorem bit it makes no sense given this kind of transformation)</p>

How to use spot instance with amazon elastic beanstalk?. <p>I have one infra that use amazon elastic beanstalk to deploy my application.
I need to scale my app adding some spot instances that EB do not support.</p>
<p>So I create a second autoscaling from a launch configuration with spot instances.
The autoscaling use the same load balancer created by beanstalk.</p>
<p>To up instances with the last version of my app, I copy the user data from the original launch configuration (created with beanstalk) to the launch configuration with spot instances (created by me).</p>
<p>This work fine, but:</p>
<ol>
<li><p>how to update spot instances that have come up from the second autoscaling when the beanstalk update instances managed by him with a new version of the app?</p>
</li>
<li><p>is there another way so easy as, and elegant, to use spot instances and enjoy the benefits of beanstalk?</p>
</li>
</ol>
<p><strong>UPDATE</strong></p>
<p>Elastic Beanstalk add support to spot instance since 2019... see:

<p><strong>I'd like the background colours of columns <code>B-D</code> to change automatically when I update the values in column <code>A</code></strong></p>
<p>Is that possible? I'm looking for a solution that will work with any colour, without preprogramming the sheet in some way to be aware of a fixed set of colours.</p>

learned my lesson [6]. last thursday my best friend flew in town with her bf, and we were giving him a tour of our uni and our hs. i've already moved back home for the summer, and i've occasionally smoked in my car w/ my pipe, but now it's my only way. we were smoking in my car and we decided to go to the beach to also drink. i'm stopping at a light to make a right to be pulling up to the ocean, and i turn to see a sheriff parked at the other light. i think *okay cool i am stopping it will be okay* trying not to freak out, just in case everything wasn't okay. i stop, turn right, and i'm gripping my pipe as i just stare into my rearview. his lights get brighter as i'm locking away my stash away in the console, yelling at my best friend to hide the rum as the siren goes off. the cop was super aggressive and scared the shit out of me. i honestly thought i was going to go to jail. but i dunno if the eye drops made it looked like i was crying or if i actually was, but he softened up towards the end & let us go because i was *an honest decent kid.* i'm laughing about that now, but only cause i'm trying to burn through my stash cause i'm never bringing anything other than a blunt into my car. wasn't the most safe way to smoke either; so i'm glad i have this near death experience to change my ways.
tl;dr: don't smoke & drive: especially if it's not disposable but more importantly cause it's unsafe. but if you are riding dirty, make sure you have body spray & try to look like you're crying so the officer takes pity on you | 0non-cybersec

Hive: is the beetle way overpowered? Also, mitigating first player advantage.. EDIT: PLEASE DON'T READ ANY FURTHER IF YOU WANT TO HAVE POTENTIALLY GAME ALTERING STRATEGY EXPLAINED TO YOU. YOU SHOULD ONLY READ THIS IF YOU HAVE EXPLORED THE GAME ON YOUR OWN AND FEEL LIKE YOU ARE AT A DEAD END IN TERMS OF GAME PLAY. THANKS.
I've started playing Hive recently with a coworker at break times, and throughout the day (walk by and make a move sort of thing). We are having a blast but after a few dozen games we figured out that the beetle can be used to (practically) guarantee victory for the first player.
The strategy is to lay spider-bee-spider, move spider to pin opposing bee, drop beetle, move to cover bee, drop 2 pieces directly adjacent to bee, and then drop one ant and move it onto the bee, and finally drop the beetle into theist space.
You can defend against this by placing your beetle by the queen to cover the opposing beetle (or more usually just to threaten to cover it) but then you're "losing" another turn and also covering another side of your bee. Basically, unless player 1 completely messes up, they will win in about a dozen turns.
We've modified the rules to say that the beetle doesn't change the color of a queen under it, and that extends the game out enough that player 1 isn't assured victory, but assuming near-optimal play player 1 will always win.
We're seeing 80%+ win rates for player 1 with standard rules, and 60-70%+ with our beetle changes.
Are there any counters to the opening beetle-covering strategy I've outlined? Is the beetle just too powerful? If so, what can you do to mitigate it?
What other things can be done to minimize the first player advantage?
EDIT: I want to clarify that I am not saying I have an "unbeatable" strategy... what I am saying is that I *think* this strategy makes it so that player two can ONLY win if player 1 makes an error (and not even any error, but a pretty significant one). Given optimal play by player 2, they will only win if player 1 plays "moderately" optimal, for lack of a better phrase. I'm actually not that great of a player, TBH... but neither of us can figure out a scenario in which player 2 can win on their own merit, rather than strictly capitalizing on player 1's mistake.
I am sure there lots of people who are WAY better at me at this game, and so I was looking for input on how they deal with both the beetle and the first player advantage in ways that keep the game interesting. Sorry if I came off like I was claiming to be a master Hive player who can't be beat - it's more the other way 'round! *I* can't figure out if this strategy can be countered, and if it can't it sort of spoils the game for me, but maybe someone else can, which would "save" the game for me, which I really enjoy! | 0non-cybersec

Fruitloops for breakfast.. A 5 year old and a 3 year old are upstairs in their bedroom
'You know what?' says the 5 year old, 'I think it's about time we started swearing.'
The 3 year old nods his head in approval, so the 5 year old says,
'When we go downstairs for breakfast I'm gonna swear first, then you swear after me, ok?'
'Ok' the 3 year old, agrees with enthusiasm.
The mother walks into the kitchen and asks the 5 year old what he wants for breakfast.
'Shit mum, I don't know, I suppose I'll have some Fruit Loops '
#WHACK...she spanks him
He flew out of his chair, tumbled across the kitchen floor, got up, and ran upstairs crying his eyes out.
She looked at the 3 year old and asked with a stern voice, 'And what do YOU want for breakfast, young man?'

How to use spot instance with amazon elastic beanstalk?. <p>I have one infra that use amazon elastic beanstalk to deploy my application.
I need to scale my app adding some spot instances that EB do not support.</p>
<p>So I create a second autoscaling from a launch configuration with spot instances.
The autoscaling use the same load balancer created by beanstalk.</p>
<p>To up instances with the last version of my app, I copy the user data from the original launch configuration (created with beanstalk) to the launch configuration with spot instances (created by me).</p>
<p>This work fine, but:</p>
<ol>
<li><p>how to update spot instances that have come up from the second autoscaling when the beanstalk update instances managed by him with a new version of the app?</p>
</li>
<li><p>is there another way so easy as, and elegant, to use spot instances and enjoy the benefits of beanstalk?</p>
</li>
</ol>
<p><strong>UPDATE</strong></p>
<p>Elastic Beanstalk add support to spot instance since 2019... see:

Interior is a Subset of the Closure. <blockquote>
<p>$\textbf{Question:}$ Let $A$ be a set. Why is the $interior(A)\subset closure(A)$?</p>
</blockquote>
<p>I use the following definitions for $\underline{interior}$ and $\underline{closure}$ given a metric space $X$.</p>
<ul>
<li>Interior Definition: $x\in interior(A)$ if $\exists$ a neighborhood
$N$ of the point $x$ such that $N\subset A$.</li>
<li>Closure Definition: $x\in closure(A)$ if $\forall$ neighborhoods $N$
of the point $x$, $N\cap A\neq \phi$.</li>
</ul>
<p>I started trying to prove this as follows, any help would be greatly appreciated!</p>
<p>Proof: Let $x\in interior(A)$. Thus, $\exists N$ of $x$ such that $N\subset A$. Say $N_0$ is such a neighborhood of $x$ which $N_0\subset A$ holds true. Then, I get stuck here as I am trying to show $x\in closure(A)$ by showing $\forall N$ of $x$, $N\not\subset A$ holds true or $N\cap A\neq \phi$ holds true (these are equivalent).</p>

Using TypeBuilder to create a pass-through constructor for the base class. <p>Say I have a <code>SpaceShip</code> class, like so:</p>
<pre><code>public class SpaceShip {
public SpaceShip() { }
public SpaceShip(IRocketFuelSource fuelSource) { }
}
</code></pre>
<p>I want to use <a href="http://msdn.microsoft.com/en-us/library/bhb2ecb2.aspx" rel="nofollow noreferrer"><code>TypeBuilder</code></a> to create a type at run-time which inherits from SpaceShip, and defines one constructor for each of the ones in SpaceShip. I don't need the constructors to actually <em>do</em> anything except pass their arguments up to the parent ("pass-through" constructors). For example, the generated type would look something like this if expressed in C#:</p>
<pre><code>public class SpaceShipSubClass : SpaceShip {
public SpaceShipSubClass() : base() { }
public SpaceShipSubClass(IRocketFuelSource fuelSource) : base(fuelSource) { }
}
</code></pre>
<p>To complicate things a bit, I don't actually know which class the generated type will be inheriting from until run-time (so I'll have to take into account any number of constructors, possibly with default parameters).</p>
<p>Is this possible? I think I could figure it out if I had a general direction to start with, it's just that I'm completely new to <code>TypeBuilder</code>.</p>
<p>Thanks!</p>

Complete Metric Space if and only if. <p>Let <span class="math-container">$(X,d)$</span> be a metric space. Let <span class="math-container">$\mathcal{C}$</span> be the set of all collections <span class="math-container">$\{O_i\}_{i=1}^\infty$</span> of non-empty closed subsets such that <span class="math-container">\begin{align*}
&(a) O_{n+1}\subset O_n \forall n \\
&(b) \lim\operatorname{diam} (O_n) = 0 \ as \ n \to \infty
\end{align*}</span></p>
<p>Prove that <span class="math-container">$X$</span> is complete if and only if <span class="math-container">$\forall C \in \mathcal{C}$</span> <span class="math-container">\begin{align*}
\bigcap_{A\in C} A \not= \emptyset
\end{align*}</span>
For the <span class="math-container">$if$</span> part: For every <span class="math-container">$n$</span>, choose <span class="math-container">$x_n \in O_n$</span>. Then since <span class="math-container">$O_{n+1}\subset O_n$</span>, the set <span class="math-container">$\{x_n,x_{n+1},x_{n+2},\cdots\}\subset O_n$</span>. Since <span class="math-container">$\lim\operatorname{diam}(O_n) = 0$</span>, for any <span class="math-container">$\epsilon > 0$</span> choose a natural number <span class="math-container">$N$</span> so that <span class="math-container">$\operatorname{diam}(O_n)<\epsilon$</span> for <span class="math-container">$n\geq N$</span>. This means that for any <span class="math-container">$n,m \geq N$</span>, <span class="math-container">$|x_n-x_m| \leq\operatorname{diam}(\{x_{N},x_{N+1},\dots\}) \leq\operatorname{diam}(O_N) < \epsilon$</span>. So <span class="math-container">$\{x_n\}$</span> is a Cauchy sequence. By completeness of <span class="math-container">$X$</span>, <span class="math-container">$\{x_n\}$</span> converges to a point, <span class="math-container">$a$</span>. By <span class="math-container">$O_n$</span> being closed it must contain <span class="math-container">$\{x_n,x_{n+1},\dots\}$</span>. Thus, for any given <span class="math-container">$D\in\mathcal{C}$</span> we get
<span class="math-container">\begin{align*}
a\in \bigcap_{A \in D} A.
\end{align*}</span>
hence non-empty. </p>
<p>Also, I am not sure how to start the other direction. I think you need to look at the tails of each sequence </p>

How to install gcc-4.6 (4.6.3-1ubuntu5) Source Package. <p>I have recently started working on ubuntu and I have been facing a lot of difficulties installing programs in it.
I don't know how I managed to install NetBeans and JAVA JDK and JRE.
Unfortunately the NetBeans came without C++ compiler and debugger. I've been googling for two days and all I could find and understand was some thing like this:</p>
<pre><code>sudo apt-get install build-essential
sudo apt-get install gcc g++
sudo apt-get install gdb
</code></pre>
<p>I finally -don't know how- installed the compiler but still no debugger.<br>
Then I start doing some crazy stuff. I purged <code>gcc</code>, <code>g++</code>, <code>gdb</code> and not sure what else.
Anyway I downloaded the <code>gcc-4.6</code> (<code>4.6.3-1ubuntu5</code>) Source Package from this link: <a href="http://packages.ubuntu.com/source/precise/gcc-4.6" rel="nofollow">http://packages.ubuntu.com/source/precise/gcc-4.6</a>
And as you may guess didn't know how to install it.
So please any help would be greatly appreciated ^_^</p>

Analogues of the elementary symmetric polynomials for the alternating group. <p>In the case of three variables, the elementary symmetric polynomials are
$$ \begin{align}
e_1(X_1,X_2,X_3)&:=X_1+X_2+X_3, \\
e_2(X_1,X_2,X_3)&:=X_1 X_2+X_1 X_3+X_2 X_3, \\
e_3(X_1,X_2,X_3)&:=X_1 X_2 X_3. \\
\end{align}$$
Knowledge of the values of $e_1,e_2,e_3$ determines the variables $X_1,X_2,X_3$ up to any permutation of $S_3$. That is, if
$$
\begin{align} e_1(X_1,X_2,X_3)&=e_1(Y_1,Y_2,Y_3), \\ e_2(X_1,X_2,X_3)&=e_2(Y_1,Y_2,Y_3) ,\\
e_3(X_1,X_2,X_3)&=e_2(Y_1,Y_2,Y_3),\\ \end{align}$$
then there exists a permutation $\sigma \in S_3$ such that $$X_i=Y_\sigma(i) ,$$
for all $1 \leq i \leq 3$.</p>
<p>I'm curious as to whether there exist other "less symmetric" polynomials, say $\{P_n(X_1,X_2,X_3)\}_n$ such that having
$$P_n(X_1,X_2,X_3)=P_n(Y_1,Y_2,Y_3) $$for all $n$ implies that there exists an <em>even</em> permutation $\sigma \in A_3 \subsetneq S_3$ for which $X_i=Y_\sigma(i)$ for all $1 \leq i \leq 3$.</p>
<p>I have tried keeping two of the elementary symmetric polynomials, replacing the third, but that didn't work out. </p>
<p>I would appreciate help with finding such polynomials $P_n$ (if they exist). Thank you! </p>

Intersections of convex hulls. <p>Given a set of $n$ points $\{A_1, \ldots , A_n\}$ of the plane and every possible triangle formed with $3$ points $A$, I would like to describe the intersections fo theses triangles. By intersection, I mean the part of the plane that is covered by the interiors of the triangles that intersect.</p>
<p>I am describing these triangles with convex hulls. For exemple, the triangle $A_1A_2A_3$ is represented by $\operatorname{Conv}(A_1, A_2, A_3)$.</p>
<p>I would like to define a set of convex such as every triangle (seen as a convex) is intersecting with at least of convex of this set. So basically, I would like to describe these intersections in order to count them or manipulate them.</p>
<p>I've heard of Helly's Theorem but I can't see a way to use it without knowing if the convex hulls are intersecting.</p>
<p>I am totally open to change my representation of triangles (for example by using something else than convex hulls) and I am not looking for algorithm to do it. If possible, my idea is to describe them 'mathematically'.</p>
