Is it possible to delete from own table without tmp table

How to get a toddler to start chewing and eating solids? My son is 18 months old and still doesn't want to chew and eat solid foods. We have to blend soups and other food into purée for him to accept it. If there is even a slight solid, he will automatically push it out of his mouth with his tongue.  I have had a breakthrough with breakfast where I don't blend as much and leave it a little chunky. He ate it but still pushed chunks of soft banana that were bigger out.  Some of my friends have kids that are 4-5 months younger, who are eating chicken cutlets.  Any ideas or proven methods for getting a child to start eating solids? How to pick one number from each sorted list so that the difference between the minimum and maximum is as small as possible? Local file access with JavaScript Is there local file manipulation that's been done with JavaScript? I'm looking for a solution that can be accomplished with no install footprint like requiring .  Specifically, I'd like to read the contents from a file and write those contents to another file. At this point I'm not worried about gaining permissions and am just assuming I already have full permissions to these files. Blurry Text On Model After Render TikZ: Having circle borders only grown to the outside Automating the scanning of graphics files for corruption Does anyone know of a way to check graphics files (particularly JPEG, GIF, and PNG) for corruption (preferably in an automated way)?    Explanation:  A few days ago, a command worked incorrectly and ended up deleting thousands of graphics files from a FAT32 volume that was practically out of space. I’ve used several different file/photo-recovery programs, but naturally, they are limited in how much they can recover (though fortunately the volume has 8KB clusters, which helps somewhat).  Anyway, some of the larger files, that were fragmented, are now corrupt. Some of them are not even real files at all (the recovery software merely dumped the clusters that were pointed to by now-overwritten directory entries), while others are broken because of fragmentation.  Moreover, because some picture formats embed a smaller version of the picture as a thumbnail, scanning the thumbnails for corruption is not reliable because it may be intact while the actual file (i.e., the picture when viewed full-size), could be corrupt.    Here are a couple of examples:      Here’s the second one. It’s so damaged that it doesn’t display anything.    (A third one wouldn’t even upload because it doesn’t even have the correct header!) ¿Can you help me with axiom of regularity? I understand that if we define a set such that $A=\{A\}$ we have then a contradiction because of regularity axiom, thus, a set can not be a member of itself. My question is; how can it be so, if I define a set $A=\{A,b\}$ ($b$ disjoint from $A$)?  Thanks. Verb agreement with "what" This came up when reviewing a written English exercise, and I realized that I don't entirely trust my intuition on the answer.  Which of the following is correct?  Or are both valid?  (Or is it strongly advisable to rewrite the sentence in some other way?)   "I see what appears to be a man and his son." "I see what appear to be a man and his son." How can an 18 month old be taught that bullying is not ok? He seems to like causing the trouble it brings upon him, and bullying, mean acts also seem to please him. He likes to sit on his younger cousin (my son), push him down, and steal his toys. His parents seem to be at a loss about it, and I don't really have any good suggestions to give. Thanks. Finding a set of continuous functions with a certain property 2 I need help finding the set of continuous functions $f : \Bbb R \to \Bbb R$ such that for all $x \in \Bbb R$, the following integral converges:  $$\int_0^1 \frac {f(x+t) - f(x)} {t^2} \ \mathrm dt$$  I think it might be the set of constant functions but i havent been able to prove it :(   I was thinking that you can use the stone weiestrass theorem considering the set of continuous functions on a closed  interval(non trivial) ,and a subset which contains the set of continuous functions whose integral above diverges in some point in that interval along with  with the set of constant functions. So in order to solve the problem i need only to prove that if two functions do not meet the condition of the problem then their product does not as well .  I hope you can provide some insight and thank you . Benefits of Toad houses I have a few red Toads and a Toad is just hanging out in town. I see an option to buy a red Toad house, ostensibly for him. Are there any added benefits of purchasing this or are the colored Toad houses just cosmetic? I love making our own bread - we rarely buy shop bought, but it tends to go off very quickly. Part of the appeal is that it doesn't have any "junk" in it - artificial preservatives - which I'm sure contributes to the lovely flavor. Is there anything natural I can add to it to stop it going moldy so fast? Does installing and using Wine open up your Linux platform to Windows viruses? Just wondering if installing Wine might open up a fairly solid Linux desktop to the world of Windows viruses.  Any confirmed reports about that?  Would you then install a Windows antivirus product under Wine? NIST randomness test p values I have a binary sequence of length $2^{20}$. I am using the NIST statistical test, assess.   What should be taken for ./assess and  How many bitstreams? in this test? In the final Analysis report, what p-values should be there to pass this test? Unable to install Ubuntu on Lenovo Y500 I am pretty sure it shouldn't, but want to make sure that I am doing this correctly in a proposal that I am working on.  Should job titles like "Project Manager" ever be capitalized, and if so when?  In particular I am concerned about capitalization in sentences like this where the title refers to a specific person, not the role in general.     "The Project Manager will   evaluate the alternatives and offer a   solution."   I'm a lot more certain that it should NOT be capitalized in sentences like this.     "A project manager is the person who   manages the budget and deliverable for   a project." These 2 questions have clearly wrong answers with upvotes. And they're still getting votes.  The log file one especially could be tried out, it would fail, but someone still voted it up. A downvote and comment has no effect.  Like we have "vote to close", what about a "vote to delete" for answers. I'd suggest a fairly high rep limit. Or badge ownership realting to the question tags (eg SQL Server)   (SF)   (SO)  Could be similar to this meta question: What is the name of the black&white movie about a mirror Earth (universe)? Astronauts in a spaceship have an accident and fall back to the Earth. They are tried in court. It turns out to be a mirror Earth. As I remember (though maybe I'm not totally right) only one professor knows something about that and in the final scene he crashes into a mirror with his wheelchair. In another scene an astronaut realizes that his name can be read from the mirror directly.  Does anybody remember the movie? Is there any way to add if elif and else in drivers?  Given the way we do if and else, here are two examples out of few other things i tried to get the statement right but unable to do so:  var-3.5 if (var&lt;0) var+3.5 elif (var&gt;0) else 1  var-3.5 if (var&lt;0) elif var+3.5 (var&gt;0) else 1   And also if there's any other way to add multiple if/else similarly? Comment deletion notification I think you should be notified if anything of yours is deleted or even flagged, preferably with some explanation (even if it's a simple categorisation like #rude, #irrelevant, #incorrect) and who did it.  Recently, a couple of comments of mine vanished without warning or evidence afterwards. I'm fine with deletion, but I think it should be used sparingly and be based on democratic decisions. What's the harm of letting a comment simply sit with no up-votes or responses rather than outright removal? Or allow downvoting and then negatively voted comments are hidden by default?  I get the impression that anything I post could be deleted. Very few people want to be unpopular or do the wrong thing. It takes time to understand what something is about and how best to use it (this site). Whether or not what I posted deserved to be deleted is irrelevant because I got no feedback. No-one can learn without feedback. The number of frivolous comments with many upvotes I've seen shows how inconsistently the rules are applied. A community that gives too much power to highly rated users won't grow but turn stagnant.  Sorry if this was rude, inappropriate or pathetic. I'm aware that similar discussions have occurred. In any case, I'll continue to use the site and move on...
