Is there an online / incremental / parallel version of t-SNE
Are there any versions of t-SNE for streaming data?

Prove that the convergence of $\sum{a_n}$ implies the convergence of $\sum{\sqrt {a_k} \over k}$ if $a_n \ge 0$.  Proof:  I will attempt to show that the cauchy criterion is met so $${\sum_{k=n}^m {\sqrt {a_k} \over k}} \le \epsilon $$ for all $n,m \le N_1$. Im disregarding the absolute value since its all positive terms.   Since $\sum{a_n}$ converges, we know that the $\lim \limits_{n \to \infty} a_n =0$ So there exists some $N_2$ such that for all $n \ge N_2$, $$   a_n \lt \ {{(m-n)}^2k^2(\epsilon)^2} $$ I am again disregarding the absolute values because its always positive Let N=max{$N_1,N_2$} then for all $n,m \ge N$ $$\sum_{k=n}^m {\sqrt {a_k} \over k} \le \sum_{k=n}^m {\sqrt {{(m-n)}^2k^2(\epsilon)^2} \over k} \le \sum_{k=n}^m{(m-n)(\epsilon)} = \epsilon $$  Maybe this is just crazy, should I just use Cauchy-Schwarz inequality and forget about this or could I possibly make this method work? I don't mean people with low self esteem.  But there are people who feel happy at being able to make other people laugh at their own expense. I remember someone telling me there is a word for them, I can't find it.  Let me explain:  I sometimes, while sitting with a group of people, might just tell them a personal embarrassing story, which might be completely fabricated, to make other people laugh. And when they laugh, I feel happiness.  I'm also self deprecating, but not in a way that I hate myself, rather,  just my work (I'm a screenwriter) and knowing I can do better. I do not self deprecate myself in public (I don't praise myself either).   Edit: Now that its mentioned, I think the word I'm talking about was used to describe a person's sense of humor. Or it could be a word used to describe a psychological trait/disorder.  Edit: I just looked up humor styles on Wikipedia. And after reading it, I guess the word that closely matches what I'm looking for is 'Affiliated Humor' but in a 'Self Defeating' style. How to put small numbers outside the pie slices without making a mess I'm new to LaTeX and need some help with my figures.

Thanks in advance :) Is it possible to have an object ignore a certain light source but still be affected by others? I want to create an effect on a character where their skin and clothing are effected by two different light sources. The clothing should only reflect a bright bounce light, but have the skin should not be affected by this light source.    In the example image I have two objects a cube, a sphere and three emission  lights . I want the two white lights to hit both objects, and I need the purple light to hit and reflect off of the sphere, but ignore the cube entirely (no reflections).  Someone suggested to composite the layers together, it works... but this is very impractical and cumbersome because it forces the background to be transparent and it will be a pain to try and layer together a more complex scene, especially if its animated which is what I want this effect for.  I know you can have objects ignore shadows and all kinds of other things so im hoping someone knows how to get an object to ignore light with a few settings. Spanning volume disk usage I have two SSD disks of 256GB and I want to create a single spanning volume of 512GB. I am using Windows 10. What I want to know is how will Windows handle this under the hood.  Will the first disk fill up before the second one starts being used, or will Windows use both disks. For example, if I have 256GB of data on the spanning volume, will it be divided to 128GB on first and 128GB on second physical disk or will it all be on the first disk with the second disk empty? Would this behavior be any different if I were using two HDDs? How do I construct the $SU(2)$ representation of the Lorentz Group using $SU(2)\times SU(2)\sim SO(3,1)$ ? Is there ever a point you aren't following Harry's perspective? In the Harry Potter books, is there ever a point that is not from the perspective of Harry? There are a few times you are inside Voldemort's mind, but that is really just a an extension of Harry's mind.  Is there ever a point where you are in the perspective or the mind of someone other than Harry (as in hearing their thoughts)? Can a PC be a lich? The heading says it all, can a PC be a lich? If so, how? The DMG hints that the Book of Vile Darkness contains the secrets of how; there is nothing official otherwise. Html form in email Our team is developing a new system and it has a Warehouse table that must have a hierarchical relationship between entries since a customer can have 1st, 2nd, 3rd and Nth degree warehouses.  We first thought that  was the best way to do it. By creating a Parent and a Child column on the table and then making Parent the FK to Child (on the same table) but friend DBA told us that there is a different way.  So, for instance, we had thought about making a table like this:  CREATE TABLE Warehouse( filterId INT PRIMARY KEY IDENTITY, parentId INT NOT NULL, active BOOL DEFAULT 1, warehouseName VARCHAR(30) NOT NULL, FOREIGN KEY parentId REFERENCES Warehouse(filterId)  | FILTERID   | PARENTID | ACTIVE | WAREHOUSENAME | -------------------------------------------------- |          1 |        0 |      1 | N WAREHOUSE 1 | |          2 |        1 |      1 | ROOM 1        | |          3 |        1 |      1 | ROOM 2        | |          4 |        1 |      1 | ROOM 3        | |          5 |        1 |      1 | ROOM 4        | |          6 |        2 |      1 | SHELF 1       | |          7 |        2 |      1 | SHELF 2       | |          8 |        2 |      1 | SHELF 3       | |          9 |        2 |      1 | SHELF 4       | |         10 |        2 |      1 | SHELF 5       | |         11 |        2 |      1 | SHELF 6       | |         12 |        2 |      0 | SHELF 7       | |         13 |        3 |      1 | BOX 1         | |         14 |        3 |      0 | BOX 2         | |         15 |        3 |      1 | BOX 3         | |         16 |        3 |      1 | BOX 4         | --------------------------------------------------   But this DBA said that we should work on something like this:  CREATE TABLE Warehouse( filterId VARCHAR(20) PRIMARY KEY, active BOOLEAN DEFAULT 1, warehouseName VARCHAR(30) NOT NULL)   | FILTERID   | ACTIVE | WAREHOUSENAME | --------------------------------------- | 1.00       |      1 | N WAREHOUSE 1 | | 1.01       |      1 | ROOM 1        | | 1.02       |      1 | ROOM 2        | | 1.03       |      1 | ROOM 3        | | 1.04       |      1 | ROOM 4        | | 1.01.01    |      1 | SHELF 1       | | 1.01.02    |      1 | SHELF 2       | | 1.01.03    |      1 | SHELF 3       | | 1.01.04    |      1 | SHELF 4       | | 1.01.05    |      1 | SHELF 5       | | 1.01.06    |      1 | SHELF 6       | | 1.01.07    |      0 | SHELF 7       | | 1.01.01.01 |      1 | BOX 1         | | 1.01.01.02 |      0 | BOX 2         | | 1.01.01.03 |      1 | BOX 3         | | 1.01.01.04 |      1 | BOX 4         | ---------------------------------------   Which way should we follow?   On one hand we have a relationship between parentId and filterId; on the other we do not have any relationship, but it is easy to understand where does the entry belong.  Not all the warehouses are of the same level - that's what I mean by degree. They should be ordered like: For Customer A, 1 is parent of 1.1 and 1.2, 2 is parent of 2.1, 3 is parent of 3.1 and 4 is parent of 4.1 and 4.2 - but 1, 2, 3 and 4 are of the same level (1st level), and 1.1, 1.2, 2.1, 3.1, 4.1 and 4.2 are also of the same level (2nd level) but not of the same parents.

What Wording Did Witches and Wizards in Other Cultures Use for Spells? The spells that we know about in the Harry Potter world all seem to be either in Latin, derived from Latin, or resembling Latin.  This makes sense for the European World, but there were likely witches and wizards in Africa, Asia, and the Americas.  These cultures would have developed independently, and the magical people in them would likely have still found ways to cast their spells.  Do cultures with languages that did not derive from Latin use the same words and phrases that are related to Latin for their spells?  Or did they have other phrases based on the languages in their cultures? I read on  that Ubuntu will no longer use the familiar file size units we all know by now (kB, MB, GB, TB) and switch to a different IEC standard (KiB, MiB, GiB, TiB). If this is true, I would like to know what's the reasoning behind this change, and the impact (if any) this change has, especially with multiplatform applications or applications run with Wine. Why does just splitting an Ethernet cable not work? I thought the Ethernet is logically a one-line communication bus (for argument's sake, I am excluding hubs). All machines attached on the bus hears the same signals and the machines themselves try to avoid collisions by randomly backing off.    If so, why would splitting one Ethernet line from my home router into two and connecting two computers not work? Why do I have to add a switch to it?  What the Internet said would not work.                                                             +----------+                                                +----------&gt;|computer 1|                                                |           +----------+     +------------------+       +---------------+     |4 port home router+------&gt;|simple splitter|     +------------------+       +---------------+                                                |           +----------+                                                +----------&gt;|computer 2|                                                            +----------+   What the Internet said I should do                                                             +----------+                                                +----------&gt;|computer 1|                                                |           +----------+     +------------------+       +---------------+     |4 port home router+------&gt;|    switch     |     +------------------+       +---------------+                                                |           +----------+                                                +----------&gt;|computer 2|                                                            +----------+   Is this because of the signal degradation (reduced electric current)?    Thank you for all the answers! The reason why I did not just use the two ports of my home router is...  The 4-port gigabit router is in my room, and I had put a computer in another room (also my room, though). Since a wired network is far more reliable and secure, I had bought a long Ethernet cable and and connected the computer to the router. Now I was thinking about adding another computer to that room. I could buy another long Ethernet cable, but then there will be two cables between the rooms. The one line already is a minor annoyance, so I thought if I could share the one line between the two computers in that room. A switch would work, but it requires power and is a little bit pricey. That is why I wondered why it would not work to simply split the physical Ethernet cable.  Apparently I do not completely understand how Ethernet and a switch work. I just have some bit of knowledge I heard in my college class. Can chicken not completely cooked then cooled be fully cooked later? I want to burn Ubuntu Minimal CD ISO to an old, 1 GB USB thumbdrive. Regular ISO doesn't fit. I already tried Startup Disk Creator and Unetbootin but both failed. I tried installing GRUB and pointing it to boot like this:  insmod part_msdos linux /linux initrd /initrd.gz   but it doesn't work. I also tried dd but I ended up with not bootable drive.  Rufus worked on Windows with the same thumbdrive but I no longer use Windows.  What else can I do?
