soda reaction. I work as a busser at a restaurant and when I put silverware in soda glasses the soda occasionally fizzes up as if it was just poured. What caused this exactly? Is it a certain food that was still on the silverware? I have not been able to reproduce this when I try. | 0non-cybersec

How do you go from a sip.voidptr (QImage.constBits()) to a ctypes void or char pointer?. <p>I'm using python and of course you can't loop through every pixel of a large image very quickly, so I defer to a C DLL.</p>
<p>I want to do something like this:</p>
<pre><code>img = QImage("myimage.png").constBits()
imgPtr = c_void_p(img)
found = ctypesDLL.myImageSearchMethod(imgPtr, width, height)
</code></pre>
<p>But this line
imgPtr = c_void_p(img)
yelds </p>
<blockquote>
<p>builtins.TypeError: cannot be converted to pointer</p>
</blockquote>
<p>I don't need to modify the bits. Please teach me your Jedi ways in this area.</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>

iPhone Whatsapp Lockscreen Notification Problem. <p>Since upgrading Whatsapp to version 2.18.52 contact names do not appear on whatsapp lock screen notifications. For example, if I get a message from Mom, whatsapp only displays the whatsapp logo and “message”, without displaying the sender. I used to be able to see just the contact name (“Mom has sent you a message”), but now, no Names are displayed. This just happened as I updated to ios 11.3.1. Anyone having a similar problem? Please advise how I can fix this issue. </p>

The output displays uptime, temperature, RAM usage and HD usage.
Example of output:

User IDs containing URIs. <p>When adding a User ID to your OpenPGP key, you are typically asked (for example by GnuPG) to provide a name, a comment, and an email address (where each part is optional).</p>
<p>This format (<code>Name (Comment) <email address></code>) is described by <a href="https://tools.ietf.org/html/rfc4880#section-5.11">RFC 4880, section 5.11 (User ID Packet)</a>:</p>
<blockquote>
<p>By convention, it includes an <a href="https://tools.ietf.org/html/rfc2822">RFC 2822</a> [<a href="https://tools.ietf.org/html/rfc2822">RFC2822</a>] mail name-addr, but there are no restrictions on its content.</p>
</blockquote>
<p>While it says it’s only a "convention" and there are "no restrictions on its content", the first sentence of this sections reads:</p>
<blockquote>
<p>A User ID packet consists of UTF-8 text that is intended to represent the name and email address of the key holder. </p>
</blockquote>
<p>I assume (please correct me if I’m wrong) that "intended to represent the name and email address" is not normative. So that would mean:</p>
<ol>
<li>I may specify any kind of content (it does not have to represent a name and/or an email address).</li>
<li>If I specify a name and an email address, I don’t have to follow the address format described in RFC 2822.</li>
</ol>
<p><strong>Is this correct?</strong></p>
<p>If so, I could specify any kind of URI (using <a href="http://tools.ietf.org/html/rfc3986#appendix-C">angle brackets to delimit it</a>). As the URI scheme would be included (contrary to the "convention" format), it could, for example, prevent people mistaking an XMPP address for an email address.</p>
<p>Examples of possible User IDs:</p>
<ul>
<li><code><mailto:[email protected]></code> (my email address)</li>
<li><code><xmpp:[email protected]></code> (my JID)</li>
<li><code><tel:+1-201-555-0123></code> (my telephone number)</li>
<li><code><acct:[email protected]></code> (my Security SE account)</li>
<li><code><https://example.org/></code> (my website)</li>
</ul>
<p><strong>Is this sensible, maybe even recommended? Will it break something?</strong></p>
<p>I especially wonder if tools (like keyservers, mail clients or key chains) will still find/associate a key with an email address if the full URI is specified (<code><mailto:[email protected]></code>), and if they <em>won’t</em> interpret an XMPP address (<code><xmpp:[email protected]></code>) as email address.</p>

Making a Battle Bus. So, a friend of mine is DMing a 3.5ed campaign, and we're discussing how to work up an armored wagon type deal, a Battle Bus.
Previous campaigns have had just a wagon with a mounted ballista...but I want to put on two ballistas, a reinforced frame, and max out the 2 ton capacity listed in the PH with players, equipment, and armored plating.
Has anyone else done anything like this previously?
By my careful calculations, iron plating forming walls and a roof would involve three 3 meter by 2 meter sections, and two 2 meter by 2 meter sections, which with a thickness of 1/4" would have a total weight of about 2250 pounds and therefor would cost about 225 gold for materials and therefor about 775 to have made. At 1/4" it would have about 8hp but hardness would still be 10 and break DC should still be 30. If mithril could be used, it could be made twice as thick with the same weight.

<p>It worked fine on my old 17" and 20" displays, now I've noticed on my new 27" LCD, it's inaccurate, so I have to change the 4th line to be more accurate, isn't Toolkit.getDefaultToolkit().getScreenResolution() supposed to get the accurate DPI, why it's not correct, for my app to work on other machines with different display sizes and DPIs, how to automatically adjust the 1.15 I have manually put in ?</p>
<p>PS : Not only my Java app's DPI is inaccurate, but also when I looked at several other apps on Windows 7 such as paint.exe or paint.net, their inch and cm are also in correct. You can try them on your machine.</p>

I’m [23F] not sure what to do in life. Hi reddit. Not really sure if this is the correct subreddit for me or if I could post this anywhere else but I’m really stuck.
I’ve been working in a bank for almost 3 years now and I don’t really like it here. They put all the employees in unbelievable amounts of stress and it feels as if I’m dragging myself to work every morning. It’s not as if I’m not doing well with work or I’m getting scolded a lot, I’m actually getting praised for the job I do and the boss wants to promote me. The thing is, I’m just tired of working here. The promotion has a bond of 3 years (if I take it). If I don’t then I’ll just be stuck here. I feel like I want to leave but I don’t know what job I want to do. I sure as hell don’t want to do banking anymore. I just don’t know what I really want and I don’t know what I’m good at. Our team also looks brand new to when I started. A whole lot of new faces since most of those I was close to has left and moved to different parts of the world. Maybe I want to move too? I really am just stuck. | 0non-cybersec

Prime ideals in Quotientring. <p>Consider <span class="math-container">$k[X,Y]/(X+Y)$</span> where k is a field. The task is to find the prime ideals of that ring. As far as I know, these correspond to the prime Ideals of <span class="math-container">$k[X,Y]$</span> that contain <span class="math-container">$(X+Y)$</span>. Since this is generated by one element, namely <span class="math-container">$(X+Y)$</span>, these must devide <span class="math-container">$(X+Y)$</span>. The only prime ideal that does so would be <span class="math-container">$(X+Y)$</span>. Therefore the only prime Ideal of <span class="math-container">$k[X,Y]/(X+Y)$</span> is <span class="math-container">$(X+Y)$</span>. Is this correct or are there mistakes in my argumentation? Also, do I need to care for the (0) Ideal at one point? Thanks in advance!</p>

What is the use of the Rofe-Beketov formula?. <p>Let $y_1(x)$ be an elementary solution of the Sturm-Liouville equation,</p>
<p>$$ \frac{d}{dx}\left( p(x)\frac{dy}{dx} \right) + q(x)y = 0 $$</p>
<p>It is well known that a second linearly independent solution may be computed from the reduction of order formula, provided that $y_1(x)$ is nonvanishing. I came upon a formula attributed to Fedor Rofe-Beketov which relaxes this constraint and claims to give a second linearly independent solution without any requirements as to the oscillation of $y_1(x)$:</p>
<p>$$ y_2(x) = y_1(x)\int \frac{(p(t)^{-1} - q(t))[(y_1(t)^2 - (p(t)y_1(t)')^2]}{[y_1(t)^2 + (p(t)y_1(t)')^2]^2} dt - \frac{p(x)y_1(x)}{y_1(x)^2 + (p(x)y_1(x)')^2} $$</p>
<p>which can be established by a somewhat lengthy but relatively straightforward computation. But in every example I can think of where a second solution must be determined when only one is known, it can be obtained by the ordinary reduction of order formula. For other problems, any algorithmic solution procedure should automatically gives both fundamental solutions and so neither formula is necessary. Perhaps this merely signifies a lack of imagination on my part, but are there any examples of applications of the Rofe-Beketov formula actually being required to complete the solution of an ODE?</p>

My molestor (23M) may be doing it to another?. Throwaway account for obvious reasons. I ramble a lot & have to share some backstory, so sorry if this is long.
Before all else, it should be noted that I was being molested, raped & beaten by my grandparents/other family members & family friends. This went on for 7 years. 3 years after it started happening, I told the step mother at the time about it. Being only six, I was really embarrassed to talk about it with my father due to us being opposite genders. She instantly smacked me across the face & told me not to lie about something so serious so I never brought it up again, with anyone. Custody battles began long after & my biological father won, so I went to go live with him & the same step mum who had smacked me.
Not long after moving in, the step son, who was 12 & I 10, would make really weird comments towards me. I remember one time I was using the bathroom to which he came in & refused to leave until I finished peeing. After no longer being able to hold it in anymore, I peed in front of him thinking he'd finally leave. He didn't. He told me to open my legs & show him how I wipe myself. There were many times where it was only verbal but there was two times where he physically touched me. First one was we were at a park with the youngest step sister. She & I were on the tire swing & he was pushing us. He kept on 'accidentally' touching my butt & sometimes pinching it. We were about to get off when he put his hand down the backside of my jeans & grouped my vagina from behind. He then said this was an accident & that he was just trying to help me off the swing.
Before I talk about the second physical time, I would like to mention that he is the only son of a family of 3 girls, not including myself. The youngest female, we'll call her B was 7, followed by me 10, him 12, & the other two sisters who were 16 & 19 at the time. There were many times where my father & step mum would get into arguments because she was letting him bathe (sometimes with) B. It was always unsupervised but was fairly a fairly 'common' occurance.
The second time he touched me, we were in our play area which was the basement. We had this cabinet that was modified at the bottom so we could keep our toys in it without them falling out. Was just a tall cabinet/closet with a board at the bottom of it to keep our toys in while we were done playing. He had told me some bullshit story about how lice (which we were dealing with at the time) & how they grew to the size of a quarter if left alone. He then proceeded to tell me about how they only came out when no ones around to search for food. He said if we hid in the cabinet we may be able to see them. Me being a very curious but equally ignorant 10 year old, I believed him. We took some chips from upstairs, crushed them on the carpet & hid. Within a minute of us hiding, he pulled me closer to him. I told him no but he stuck his hand down the front of my pj's anyway. There was no insertion of fingers but he did feel around. I kept saying no, to stop but he proceeded to do so anyway. He didn't stop until I was crying so loud that we could hear the step mum heading our way. These are the only two times I can remember him getting physical with me. I haven't seen him to it or say inappropriate things to the other females.
I never told my father or the step mum because of the previous time when she smacked me. She also wasn't very fond of me & made sure I knew. Told me she'd never love me as I wasn't one of her own, told me my mother hit the train (accident & died) trying to kill herself & me, so forth. My father always took her side when it came to me, even not allowing him to 'favor me.' Only her kids. So I never told him about it either thinking he wouldn't believe me &/or wouldn't care.
I'm now in my early 20's & have since cut off all contact with this women & her children. My father & her split up when I was 16 but I later moved out on my own not long after. He & I never had a good relationship & aren't on talking terms other than "you alive?" Every 6 or so months.
Facebook decided to 'suggest' my molester as a friend about a month ago. Morbid curiosity got the best of me & I creeped his profile only to find out he's in a new relationship with a female who was an infant girl with another man. My question is, should I tell her about what he did to me or should I leave it alone? It is worth mentioning that he was charged with stagatory rape when he was 20 with two girls, 13 & 14 but the Chargers were soon after dropped. I've been thinking about whether I should do this, & how to go about it. I don't have any physical proof of my or the two girls charges either. Please, Reddit I'm at a serious loss here & don't know what to do.
**Edit** Thank you to everyone who responsed. Didn't expect so many.
I apologize for the typing errors, it was late already & this stop isn't something that's very easy to chat about. Even if I'm anonymous.
It's a hard decision because my father & I have been trying to fix our relationship for years. I feel like this will be the straw that broke the camels back for him. Alongside, my second cousin is my world, like a son to me. If my aunt heard about this, she would never let me see him ever again. It's a hard decision because these two things factor in a lot. Not only that but I've been through the court system so many times for things of this nature, that (selfish) I just don't want to go through it anymore. It's a very traumatic experience for me.
I've decided to tell her, but want to be as Anonymous as possible. While looking for the first two charges online, I came across another article of a 11 year old female he molested at a swimming pool. While I can't give her detail about my personal experience, I could email her that as well as talk very breifly about my experiences/ the other two minors he slept with? One of them was black out drunk & the other was not far behind. I say this because I've gotten some messages telling me "people change." While that's true, I don't think it's fair to say that when it's happened so many times & he's not faced any legal action.
If someone could help me with how to summarize this without anything personal to try to keep this anonymous, I'd be forever thankful. | 0non-cybersec

How do I check, if bitmask contains bit?. <p>I don't quite understand this whole bitmask concept.</p>
<p>Let's say I have a mask:</p>
<pre><code>var bitMask = 8 | 524288;
</code></pre>
<p>I undestand that this is how I would combine <code>8</code> and <code>524288</code>, and get <code>524296</code>.</p>
<p>BUT, how do I go the other way? How do I check my bitmask, to see if it contains <code>8</code> and/or <code>524288</code>?</p>
<p>To make it a bit more complex, let's say the bitmask I have is <code>18358536</code> and I need to check if <code>8</code> and <code>524288</code> are in that bitmask. How on earth would I do that?</p>

I hate you more than you could ever imagine.. Only the worst kind of person would see that their ex wants to commit suicide and put in the effort to make them feel worse. I've cried nearly every night for the past week because of this shitty situation and tonight was another one of those nights. I considered staying the night with you, and I'm so glad I didn't. I left your apartment and cried all the way home and over an hour after I pulled into the driveway. Until I logged in and saw your message, I was looking forward to seeing you tomorrow. I CAN FINISH MY TAXES MYSELF, but I wanted to come over. Now I just want to get my things out of your apartment, finally put in my change of address, and get far, far away from you. I blocked you and your "best friend" on Facebook, and for fuck's sake, don't use your creeper account to stalk me. Moving out was hard for me and I honestly did NOT want to do it, but you've made me realize what a fantastic decision I've made. I can deal with cats and a week of cold water. I can't deal with someone who wants to see me kill myself.
Edit: I can't believe I bought that "please don't fade away" crap. I can't believe I've stayed up past 3 AM for the past couple nights thinking about what might happen if we could try to work things out. I can't believe I let any of this continue after the first, second, or third time you dumped me. I'M the idiot. You're an asshole.

Self-employed and want to reduce taxes - Can you explain retirement plan options please?. Hey all,
Myself and my wife are both self-employed in the US, with no debt and a six-month emergency budget. We'd like to invest some of our disposable income into retirement planning, and after the tax bill last year, we'd like to do it in the most tax-efficient way possible, and reduce our modified adjusted gross income for the Affordable Care Act, if it makes sense to do so, although our profits have increased this year, so we may not get below threshold.
Essentially, what I would like to do is reduce both the self-employment (medicare, social security) and federal income tax that we need to pay by putting money into retirement funds. These are the retirement fund types that I know of, and my (possibly incorrect) understanding of each:
- Traditional IRA - You don't pay tax now and can reduce your declared income by that amount, which reduces federal taxes owed. It has no impact on self-employment tax. We already have these setup.
- ROTH - You pay tax on it now, but not when you withdraw in retirement. No impact now on federal or self-employment tax. We already have these setup.
- Other options - This is where I get confused - As far as I know, there are three main options - Simple IRA, SEP, and solo 401K - I don't know if any of these are better than the traditional IRA plan or why, so I'd be grateful for any advice.
Other information: We're a small business just employing my wife and I - Expected takings this year will be c. $70 - 80K, with around $55 - 60K profit and we expect to be able to put around $10K into retirement plan(s).
If someone can explain what our options are (especially with SEP, Simple and solo 401k) we'd really appreciate it.
Thanks so much.

I think I just realized saying no to that voice in my head is a possibility.. It's a weird thought, and I don't know if I can describe it with any true representation of what it is I'm actually trying to say, but this felt important to me.
I think my downfall in many attempts of dieting really just comes down to complete lack of self control. It's easy to see. Late at night I always seem to get this nagging voice in my head, for real, it nags the shit out of me. It says over and over "you're hungry", "eat something" "eat anything" "fuck your diet" "just go eat whatever you want and be good tomorrow". It seems to go on for hours and if I win, it's at the cost of my sanity, and if I lose it's at the cost of my calorie count. That voice can turn me into a ravenous glutton who goes on kitchen raids. That voice is evil.
Today I was in the car on my way home from my friends house at about 2am. This voice has already been talking to me for an hour at this point, and now that I'm in the car, drive through is just 30 seconds away. I have no idea how I did it, but I just thought "no". It felt so simple. It's almost like I never even thought to just tell it no before. I fight with it and argue it and deny it, but it's never crossed my mind to choose to just tell it to shut the fuck up. It makes me feel like I've always let it be there, and always let it win too. I don't know how much sense this makes to anyone else outside my retard brain, but for me, I'm on to something nice.
I should also note that this attempt at diet for me does feel a little different than the others because I have this worn tired feeling attitude at it. I've tried and failed over and over. This time is more like, "well, let's see how this works out. I'm not going to obsess, I'm just going to do what I can and see what happens" It's kind of like that whole tired attitude triggered me when that voice came back nagging me to just say "ooooh shuuuut the fuck up already I'm fucking tired of your shit"
**TL;TR:** fat logic / fat voice was nagging at me to eat more and I told it to shut the fuck up | 0non-cybersec

Help on Pull Up/Dip progressions coupled with existing Oly training. I do Olympic Weightlifting 3 times a week (Mo/We/Fr), now I would like to add some more upper body centric things. I started to play around with Pull Ups and Dips. I do them after my Weightlifting classes since I think it's not a good idea to fill the rest days with them.
I started with 5x5 for both, and increased the sets every workout until I was at 10x5. I planned now add in reps until I'm at 10x10. However I found that the workout takes much too long, especially when doing this after the Olympic Lifting session.
I read the Dip and Pull up Progression in the FAQ and read about the Weighted Dips.
​
Now I would like to use them instead of the BW variation I did so far, however I'm not sure how to progress and what scheme to use. I have read many posts discussing such things but fear I know am a victim of too much information :-)
​
Due to an injury I only do Squats, Deadlifts, Good Mornings in my Oly sessions right now. I have no controll about the schedule there as I follow what my trainer tells me. Can I independently of this still create a Pull Up and Dip routine for after the training?
​
I hope somebody could help me with this otherwise I will just try 5x5 with BW+5kg and add 1 kg every workout until I cannot do this anymore. | 0non-cybersec

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>My Firefox is up-to-date and equipped with Tab Mix Plus plugin. Somehow, when I am holding the left CTRL on my keyboard and left-click on a link, no tabs are created. After disabling the Tab Mix Plus plugin, the problem is resolved. I have pored over the options of the plugin and can't find anything relevant.</p>
<p>I must have missed something. Please help. :)</p>

Finiteness of intersection numbers. <p>I'm trying to understand Shafarevich's definition of intersection numbers:</p>
<p><a href="https://i.stack.imgur.com/vVGaR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vVGaR.png" alt="enter image description here"></a></p>
<p>By definition, "<span class="math-container">$D_1,...,D_n$</span> general position at <span class="math-container">$x$</span>" means that <span class="math-container">$\bigcap_{i=1}^n\text{Supp}(D_i)$</span> has finitely many points, say <span class="math-container">$P_1,...,P_k$</span> (one of them is <span class="math-container">$x$</span>, say <span class="math-container">$P_k=x$</span>).</p>
<p>I assume the neighbourhood <span class="math-container">$U$</span> is can be taken as the complement of <span class="math-container">$\{P_1,...,P_{k-1}\}$</span> so, by construction, <span class="math-container">$Z(f_1,...,f_n)=\{P\}$</span>.</p>
<p>I don't understand how we can apply Nullstellensatz, since we are dealing with the local ring <span class="math-container">$\mathcal{O}_x$</span>, and not the usual polynomial ring. I would get it if <span class="math-container">$f_1,...,f_n$</span> were polynomials, but that's not necessarily the case, so how do we justify that?</p>

Computing homology of very large posets. <p>I'm studying the homology of a couple of very large posets (one has over 4 million vertices, though the dimension is only 3). I want to show the posets are spherical (homology vanishes except in top dimension) or better Cohen-Macaulay. Because of the size, a direct computation of homology seems impossible, even with a clever program like Simplicial Homology for GAP.</p>
<p>Does anyone know of an algorithm for this sort of thing which could make life easier? I have tried to find an explicit recursive atom ordering already, but haven't found one.</p>

When can an infinite abelian group be embedded in the multiplicative group of a field?. <p>This question comes from <a href="https://math.stackexchange.com/questions/929821/field-that-contains-mathbbz-pn-mathbbz">this question by user72870.</a> That question would easily be answered if we know the cyclicity of the group in question, but, as the OP appears to be trying to prove that the group is cyclic by embedding it into the multiplicative group of a field, we cannot work under the cyclic hypothesis.<br>
So I loosed the condition and only assumed that it is abelian, but I could not find an appropriate field to embed it: finite fields are definitely out of options in reason of orders, and the ideal field must contain some sort of "cyclic algebras" for this embedding to happen.<br>
The obstacle that I emcountered is that, in the decomposition of an abelian group into cyclic ones, the orders of different summands might not be relatively prime, so that the approach to embed an anelian group into the multiplicative group of a field by embedding respectfully its cyclic factors does not work. </p>
<blockquote>
<p><strong>Edit:</strong> Thanks to the reminder of @user72870, I realised that it is impossible to embed a finite abelian group into the multiplicative group of a field, unless the group is cyclic...I don't know what I was thinking at that moment, trying to embed a general abelian group into the multiplicative group of a field.<br>
Hence I change the question to embedding a general infinite group into the multiplicative group of a (infinite, of course) field.<br>
Any help or hint will be greatly appreciated; thanks in advance.</p>

Combinatorics: Rotate 110 People 5 times. <p>I'm throwing an event where we want 110 guests (n=110) to rotate through different tables. Guests will spend a few minutes at a table, and then at a given time they'll all get up and move to a different table, however they must be in a different group of guests at their next table. This will happen 5 times total. We have the following constraints </p>
<ul>
<li>110 rotating guests</li>
<li>17 tables total</li>
<li>Guests rotate 5 times (5 rounds)</li>
<li>Guests should for the most part be with different guests at each new table they go to. </li>
<li>8 of the tables seat 7; 9 of the tables seat only 6.</li>
</ul>
<p>I've been able to work this out on a small scale (5 tables x 4 guests/ table), but I can't work it out on the larger scale. It'd also be best if there was an easy way to explain this to the guests (e.g. give everyone a number and tell them to do a simple math calc to find their new table). </p>
<p>Any suggestions are appreciated! </p>

Prove: $\frac{1}{1*2} + \frac{1}{2*3} + \frac{1}{3*4} +⋯+ \frac{1}{n(n+1)}= \frac{n}{(n+1)}$. <p>I was working on my proof by induction and I'm second guessing myself on solving the left hand side.</p>
<blockquote>
<p>Prove: <span class="math-container">$$ \frac{1}{1\times 2}+\frac{1}{2 \times 3}+ \frac{1}{3 \times 4}+ \ldots + \frac{1}{n\times(n+1) }= \frac{n}{n+1} \qquad \forall n \in \mathbb{N} $$</span> </p>
</blockquote>
<p><strong>Proof: Principle of Mathmatical Induction (P.M.I.)</strong></p>
<p>Assume: P(n):1/(1*2)+1/(2*3)+1/(3*4)+⋯+1/(n*(n+1) )=n/(n+1),∀n∈N</p>
<p>First we need to show that P(1) is true.</p>
<p>P(1):1/((1)*((1)+1) )=((1))/((1)+1)</p>
<p>P(1):1/2=1/2</p>
<p>∴ P(1) is true.</p>
<p>Next,assume P(k) is true for some k∈N.</p>
<p>P(k): 1/(1*2)+1/(2*3)+1/(3*4)+⋯+1/(k*(k+1) )=k/(k+1),is true.</p>
<p>Show P(k+1) is true.</p>
<p>P(k+1): 1/(1*2)+1/(2*3)+1/(3*4)+⋯+1/(k*(k+2) )=k/(k+2),for some k∈N</p>
<p>L.H.S.= 1/(1*2)+1/(2*3)+1/(3*4)+⋯+1/(k*(k+2) )</p>
<p>= [1/(1*2)+1/(2*3)+1/(3*4)+⋯+1/(k*(k+1) )]+1/(k*(k+2) )</p>
<p>= k/(k+1)+1/(k*(k+2) )</p>
<p>= k/(k+1)+1/(k^2+2k)</p>
<p>=0/1+1/(k^2+2k)</p>
<p>= k/(k+2)</p>
<p>= R.H.S.</p>
<p>∴ P(k+1) is true.</p>
<p>Hence,by P.M.I.</p>
<p>P(n) is true for all n∈N.∎</p>

I snooped and discovered a lie by omission...what do I do now?. I [28f] have been living with my boyfriend [30m] for a little over a year, and we've been together for about 4 years in total. For the last 6 months or so, mainly due to stress from several different circumstances in our lives right now, we've been fighting or at odds with each other a lot more than usual. However, nothing major has happened, and we're confident we can get through this "stage" in our relationship.
So here's why I need your help: He leaves his g-mail up on our shared computer quite often. If there are open g-chats up on the screen, I've definitely been guilty of skimming them quickly, often right in front of my boyfriend, just because the screen is up and it's right in front of my face. He knows I use it and more often than not is sitting right next to me when I'm using the computer, so I figure if he were really hiding something, he wouldn't leave it up on the screen like that.
However, this morning when I went to look up a movie time on the computer, I found a particularly disturbing chat left open on the screen. In the chat, my boyfriend was telling his friend not to say anything to me about him [my boyfriend] getting robbed. He said to his friend, "don't mention anything about me getting robbed. I haven't told her." ("her" being me). I could tell the chat had been "off the record" up until that line was typed. At this point, I'm not freaking out, as I have eyes and can see that everything of major worth is still in our apartment. So, I figure maybe he got jumped and hasn't told me yet? But why wouldn't he tell me? And then he would have said "jumped," anyways, right? So, I'm thinking he must have been robbed in our apartment, and my curiosity gets the best of me and so then I search the word "robbed" in his g-mail search function to see if he has been telling anyone else about this. And sure enough, I find one more conversation my boyfriend had with his brother about the incident. In this conversation, (which again was "off the record" up until this point that I can see) his brother is telling him that he should probably tell me about it, and my boyfriend replied back to him saying he would "think about it." His brother then told him I should understand because plenty of low life people break and enter into others' homes, and that money and things can always be replaced (paraphrasing). At this point, this is good enough to verify for me that this incident happened in my own apartment, where I live. And my boyfriend hasn't said anything about it to me. This conversation was held one week ago from today.
Obviously, I don't want my boyfriend to know I snooped. However, this is not one of those "I found flirty text messages!" cases. No, I found out that he got robbed-- in the apartment that we share-- and he hasn't said anything to me. I can make a lot of guesses, but I have no idea why he hasn't told me, or how he thinks that is okay.
If I do a bit of over analyzing, I would conclude that I am always the person locking our door. In fact, I've yelled at him several times in the past for leaving our apartment door unlocked, even if he's only running out for a few minutes. I'm very adamant about this, and so maybe he thinks I would blame him. Or, maybe he thinks he is "saving me" from unnecessary worrying? Or feeling unsafe? But then I ask, if we did get robbed, shouldn't I rightfully feel unsafe? And be taking extra precautions? I don't understand how a smart person can think this type of information is okay to withhold from someone else. What shoudl I do?
**TL;DR: snooped and found out my boyfriend got robbed in our apartment that we've shared for over a year together. He hasn't told me yet, and I don't think he ever will.**

The superior limit of a sequence of sets are unaltered if a finite number of terms of the sequence are changed.. <p>Problem: The superior limit of a sequence of sets are unaltered if a finite number of terms of the sequence are changed.</p>
<p>My Attempt: Given a sequence of sets $E_1, E_2, E_3....$ denoted by $E_n$ without loss of generality let the first $k$ terms of the sequence be altered so that we have the following sequence $E_1',E_2',...,E_k',....$ which we will denote by $E_n'$. Now we know that $$\lim\sup E_n=\bigcap_{n\geq1}\bigcup_{j\geq n}E_j.$$ We have to show that $$\bigcap_{n\geq1}\bigcup_{j\geq n}E_j=\bigcap_{n\geq1}\bigcup_{j\geq n}E'_j.$$ Let $x\in\bigcap_{n\geq1}\bigcup_{j\geq n}E_j$ then $\forall n\geq 1,\exists j\geq n$ such that $x\in E_j.$ Now if $n\geq k+1$ then we can use the same $j\geq n$ to get that $x\in E'_j=E_j.$ However, if $1\leq n\leq k$ then if the $j\geq k+1$ then we can again use the same $j'=j$ however if $j\leq k$ then we can always find an index bigger than $k$ as we know that $x$ belongs to all the intersections. And thus we can set $j'=j_{\text{new index}}.$ This proves the first inclusion. I guess the proof for the other inclusion works in the same manner. </p>
<p>This is my first encounter with the notion of sequences of sets and so I am not sure whether my proof is correct. I would be grateful if someone could give some feedback. </p>

MeeGo, booting from USB won't work. <p>I'm considering buying the new EEE PC X101 because it fits right into our needs. This new netbook, the version I'm interested in, runs on MeeGo though, so I wanted to have a look at this operating system before buying anything running on it.</p>
<p>So here I am, trying to boot MeeGo from a USB stick, created following <a href="https://meego.com/devices/netbook/installing-meego-your-netbook" rel="nofollow noreferrer">these instructions</a>.</p>
<p>And I'm using this img: <code>meego-netbook-ia32-chrome-1.2.0.img</code></p>
<p>I'm trying to boot it on my Core 2 Duo laptop, which I think is supported by MeeGo, but I have no luck. I get different errors every single time I try to boot.</p>
<p>Did anybody here try to boot MeeGo from a USB stick? Did it work? Did you need to do something special to get it working?</p>
