In the Stack Exchange Android app, Achievements section I can see only Today's achievements. No Yesterday, Last 7 days, Last 30 days, ... details.  Previously in the 1.0.85 version itself I saw all the achievements.   I  refreshed the page many time, but still seeing Today's achievement only.

Proving a simple graph is a connected graph Does any proof exist that a simple graph with $n$ vertices such that the least vertex degree is $\geq \frac{n-1}{2}$ is a connected graph? (i.e. does such a proof have a name?) Why do soap operas have the soap opera effect? The soap opera effect occurs when frame interpolation is used. For example, if a movie is shot at 24 frames per second and then shown on a TV screen which is capable of displaying 60 frames per second then it is possible to use a computer to do motion interpolation. In other words the computer can average (interpolate) two frames and create a synthetic third frame and stick it between the two real frames.  This interpolation makes the picture look unnatural and plastic, somewhat like soap operas look on TV, hence the name.  My understanding of why soap operas have the soap opera effect has something to do with the fact that many of them are shot using camcorders instead of film, but I am not completely sure.  Why do soap operas have the soap opera effect? What are words like "Hey Man", "Hey you", "Hey Dude" called Is there a term for words that summon someone like "Man," "Dude," "Kid" in sentences such as "Hey, Dude," "Listen up, kid," etc?    I am sure there is, but I can't really remember what it is. Can you use a Pensieve-memory to explore a place? Programmatically delete one entry from one field on one entity What's the proper way to programmatically delete one specific field entry for a multi-entry field from one specific entity? (that's specific fields and specific entities, not field types or instances and entity types)  Here's some possibilities I've looked into which don't work:   Loading the entity with entity_load(), setting the field entry to =null or =array(), then saving with field_attach_update(). It's the closest I've found but it leaves a zombie null field entry in the database which shows up as a blank row on forms until the form is saved and hook_field_is_empty() can kick in (hook_field_is_empty() is configured such that =null or =array() will flag as empty). Loading the entity with entity_load(), unsetting the field entry by key, then saving with field_attach_update(). This seems to do nothing - it seems that Drupal interprets the entry not being there as a sign to not modify it. (strangely I also sometimes get maximum query time expiration timeouts when trying this approach) field_attach_delete() - this is much too blunt: it kills all fields for the entity field_purge_data() - better, but still too blunt: it kills all entries of the field, not specific entries   So to clarify, I've got code that finds (and loads) an entity which has a field that has multiple entries, and finds a specific entry on that field that needs to be removed. I want to remove that entry completely, without touching any other entries or any other fields on the entity. How to change radius/weight of curve bezier? try scaling, change radius, but its dont work Add new JDBC Driver to connect Mathematica to SQL database $f\geq 0$, continuous and $\int_a^b f=0$ implies $f=0$ everywhere on $[a,b]$ Who are the users that work for Stack Overflow? dropping trailing '.0' from floats I'm looking for a  way to convert numbers to string format, dropping any redundant '.0'   The input data is a mix of floats and strings. Desired output:  0   --> '0'  0.0 --> '0'  0.1 --> '0.1'  1.0 --> '1'  I've come up with the following generator expression, but I wonder if there's a faster way:  (str(i).rstrip('.0') if i else '0' for i in lst)   The truth check is there to prevent 0 from becoming an empty string.  EDIT: The more or less acceptable solution I have for now is this:  ('%d'%i if i == int(i) else '%s'%i for i in lst)   It just seems strange that there is no elegant way to handle this (fairly straightforward) case in python. Discovering transformations and interactions I am teaching myself regression using Regression Modeling Strategies by Harell and the author goes at quite the length to showcase the importance of modeling interactions and transformations of the initial variables. I can't help but wonder how to approach this in a more structured/automated way when dealing with a lot of potential variables.  Can we use recursive partitioning, for example, to somehow to do the work for us and then use the output as variables, shrink the estimates with LASSO to deal with colinearity and do a final step where we use some sort of filtering for feature importance.  In my mind this will leave us with a well specified model which can be manually inspected and improved if need be, but is this reasonable? Are there other ways to approach this? Are there some resources that deal with problems like this? a cold vs flu / the flu Have you got a cold? Have you got flu? Have you got the flu?  Why can't we say a flu or the cold in the previous examples? I am a PhD student in mechE. After paying the first year tuition out of pocket, I accepted a PhD project due to desperation for funding. However, after an year I realized that I hate the project. Here I made a mistake of not leaving/changing the project, I just waited out hoping I would like the project. I also asked my advisor a couple for a different project and he did not want to change my project due to sponsor obligations. For some reason I couldn’t assert myself and stayed on. However my hate for the project only grew with time and now I am in my fifth year. I have reached a stage where I absolutely hate the project and don’t know what to do. I can hardly do any work. I feel like quitting everyday and still feel it is wrong to quit this late. I have a very substandard thesis. I am lost and feel stuck, please advise on what to do. Thanks How exactly does time slow down near a black hole? How exactly does time slow down near a black hole? I have heard this as a possible way of time traveling, and I do understand that it is due in some way to the massive gravity around a black hole, but how exactly does that massive gravity slow down time? $1^n +2^n + \cdots +(p-1)^n \mod p =$? Calculate for every positive integer $n$ and for every prime $p$ the expression  $$1^n +2^n + \cdots +(p-1)^n \mod p$$    I need your help for this. I don't know what to do, but I'll show you what I know.   Wilson's theorem The identity $X^p-X = \prod_{a \in \mathbb{F}_p-1}(X-a)$ $\exists a \in \mathbb{Z}, \ a^2 \equiv -1 \mod p \qquad \iff \qquad p \equiv 1 \mod 4$   Now can you please provide me a hint? I've heard many times that it's bad to use display: none for SEO reasons, as it could be an attempt to push in irrelevant popular keywords. A few questions:   Is that still received wisdom? Does it make a difference if you're only hiding a single word, or perhaps a single character? If you should avoid any use of it, what are the preferred techniques for hiding (in situations where you need it to become visible again on certain conditions)?   Some references I've found so far:       If you're straight-out using CSS to hide text, don't be surprised if that is called spam. I'm not saying that mouseovers or DHTML text or have-a-logo-but-also-have-text is spam; I answered that last one at a conference when I said "imagine how it would look to a visitor, a competitor, or someone checking out a spam report. If you show your company's name and it's Expo Markers instead of an Expo Markers logo, you should be fine. If the text you decide to show is 'Expo Markers cheap online discount buy online Expo Markers sale ...' then I would be more cautious, because that can look bad."   And  on the same article     We can flag text that appears to be hidden using CSS at Google. To date we have not algorithmically removed sites for doing that. We try hard to avoid throwing babies out with bathwater.   Eric Enge      The legitimate use of this technique is so prevalent that I would rarely expect search engines to penalize a site for using the display: none attribute. It’s just very difficult to implement an algorithm that could truly ferret out whether the particular use of display: none is meant to deceive the search engines or not. How can we prevent "assembly" tag being tagged to .NET assembly question I am seeing this happen again and again. Sometimes people tag the .NET and C# questions with "assembly" tag while in reality it belongs for Assembly programming questions. Title does not specify "On Hold" Testing the app, I noticed the title does not specify if a question is "On Hold" ... I haven't checked specifically, but would assume it doesn't specify as "Duplicate" either ... Or am I missing it somewhere? Is it not in the title but located/displayed some other way? If it is, this could be very confusing to users. If it isn't there, it's definitely confusing to users :-)  Using: Version 1.0.1.125 on iPad3 with iOS8 Please use UK pre-uni methods only (at least at first). Thank you. In Germany, crypto-currencies like Bitcoin are all over the news lately, making me aware of the fact I don't know much about them.  A journalistic TV program I was watching yesterday even claimed crypto-currencies are a real investment option... but I'm not so sure about that.  On one hand, I've been reading that across the ocean (USA and Canada), first ATMs have been setup that handle crypto-currencies.  On the other hand, I can not find any information if any crypto-currency is regulated (or even accepted) like common currencies (US dollar, Euro, Yen, etc.) are.  Can crypto-currencies really be regarded as a solid/conservative investment option like with regular currencies, or do I have to think of crypto-currencies like investing in "pork bellies" where risk tends to outrule chance, or are crypto-currencies more like fantasy-football and nothing one would/should seriously consider when it comes to planning an investment strategy?   Where exactly do I categorize crypto-currencies?
