Synchronized method ans synchronized blocks in Java
Is there an advantage to use a Synchronized Method instead of a Synchronized Block?
No Dropbox top panel icon since update to 18.04 Forgotten PostgreSQL Windows password Can't get unicode symbols in math mode I am trying for about a week to launch unicode-math package with XeLaTeX and got nothing. PDF is created well but all Cyrillic symbols in math mode are skipped. I tried using different math fonts - no progress at all. In log file, I found low-level error:  Missing character: There is no [cyrillic letter from input] in font cmmi12!   But all fonts used in document are Unicode ones.

How do I tokenize a string in C++? Java has a convenient split method:  String str = "The quick brown fox"; String[] results = str.split(" ");   Is there an easy way to do this in C++? Database synchronization between dev/staging and production I have a problem with WordPress database synchronization between development and production and I am wondering how other people solving it. I am aware about  but it doesn't really cover the nastier and more realistic use case.  Say I have a live WordPress website. I took a dump of everything, replicating it on our dev environment. I started making changes. 1 week later I am ready to deploy my updates. In the meantime, database on production site has changed(new posts, new comments, etc.). How do I synchronize changes between production and development during the rollout and is it possible to automate(somewhat at least) this process? People often use sans, the French word for ‘without’ in English.   What I don’t get, is when should that switch be made. When should I say sans when I really want to say without. Are there any general rules regarding usage, or is it kind of a person-to-person basis/feeling of flowerness. What is "all" in isset($wp_filter['all']) I'm a newbie in WordPress. I'm trying to understand how it generates the XHTML pages. I guess it's the function of do_action( 'hook-name' ) , but I'm stuck with the understanding of the instruction isset( $wp_filter['all] ) when reading the function do_action because I don't understand what is the meaning of the word all.  Is it a PHP feature or a WordPress one? What's the difference between "I love singing" and "I love to sing"? I would like to know what the difference is between "I love doing something" and "I love to do something".  For example:        “I love singing.”      and,        “I love to sing.”      When I was young, I was told that "love doing something" is right, but one day, I found Jessie J wrote "I love to sing" on her Instagram. Can't boot Ubuntu or Windows 8 after Ubuntu 64-bit install on Samsung series 7 Windows 8 laptop, error "All boot options are tried." I have a Samsung Chronos 7 laptop (NP770Z5E) pre-installed with Windows 8, and I wanted to install Ubuntu 13.04 alongside it, so I can dual boot. Here is what I've done:  Updated BIOS to lastest version (P04ABU) using Samsung Updater Reduced Win8 partition by half, I left the others untouched Created a bootable USB stick using  and a Ubuntu 13.04 64-bit image Disabled FastStartup on Win 8 Disabled Fast BIOS Mode Boot Mode changed to CSM OS  Update:  Also disabled Secure Boot (I had to disable it in order to select CSM OS)  After that I saved the BIOS settings, and shut down the computer. I plugged in the USB drive, powered the computer on, entered the BIOS and tried to change the boot order. Oddly, there was only one option in the boot order screen, the USB drive (HDD didn't show up in the boot priority screen). I ignored that and installed Ubuntu. I've created 3 partitions from the unused spaced left: a 8GB swap, a 100MB BIOS boot partition, and the rest to ext4, mounted in /. Boot loader installed on /sda. After a reboot, this message appears:  All boot options are tried. Press &lt;F4&gt; key to recover with factory image using Recovery or any other keys for next boot loop iteration.  So I went to the BIOS to change the boot device priority, and the list is empty! Enabling Secure Boot and Fast BIOS had no effect. I used the Ubuntu Live USB to check the disk contents, I can see the Ubuntu and Win 8 partitions. I've used Boot Repair (using the Recommended Repair), with no avail, the Boot Repair log is here:  Boot Repair showed me a message about the system being a&quot;EFI system&quot;. I suppose that means that I should have checked out the advanced settings. I don't know how to proceed. I don't know if it's a good idea to &quot;recover with factory image&quot; since I have modified the original partitions. Maybe I need to experiment with Boot Repair's advanced settings. I often find myself in the following position: I've started typing a long command at the bash prompt, but half-way through I find out I need to check something with another command. This is a problem when I'm at the console (no X), which is often the case, because then I only have the following unsatisfactory ways to do it, that I know of:    Hit ctrl+alt+F2 and log in on another virtual console, and find out what I wanted, then go back and continue  ctrl+a, type echo + space + enter, find out what I wanted, press ↑ until I find my command, ctrl+a, del x 5, ctrl+e, and continue  Highlight what I've typed so far with my mouse (if gpm is running, which it usually is), press ctrl+c to interrupt, find out what I wanted while being careful not to use my mouse to highlight stuff, then press middle mouse button on a new prompt and continue  Pray to the command line gods that the half-written command will have no adverse effects but simply fail, and gingerly press enter, then find out what I wanted, press uparrow until I get my command back, and continue  Jump into my time machine, travel back in time and remind myself to start screen before starting to type command, travel back to the present, press ctrl+a c, find out what I wanted, press ctrl+a ctrl+a, and continue   So what I want to know is, is there some more elegant way of doing this? A sort of subshell-command or similar?  I'm most interested in methods that do not require any preparations or setup to work. I really enjoyed that site. I've only posted on it once, but I enjoyed seeing other people's posts and appreciated reading about entrepreneurial dilemmas. How to add upload field in a custom taxonomy? Prove for any $a&gt;1$ there exist a natural number, $N$, such that $a^n&gt;n$ for all $n \ge N$  My attempt:  By definition, for $N$ to be a natural number $1\le N \le ∞$ for any integer $N$.  By induction, the base case $n=1$ is true because $a^1&gt;1$ which is true.  Now assume that $a^k&gt;k$ is true, then it is also true for $n= k+1$.

I might end up teaching philosophy in Finnish lukio/gymnasium. I will not get an opportunity to practice teaching it - I do get to practice teaching mathematics a fair deal, though. (The situation is somewhat unfortunate.) I have taken subject studies in philosophy at university. They amount to around 60 credits (ECTS).  Suppose I give the students an exam, which asks them to write an essay or two. After that my task is to grade the exams in a fair way and comment them in such a way that the students can learn from the feedback.  -  Suppose the task was to write an essay on the problem of universals - nominalism and realism, say. Let us say 6 points is the perfect score for this task.  I would expect the students to define nominalism and realism (2 points, maybe?) and explain the problem (2 points). Remaining two points for taking some stance and arguing for it - realism is more reasonable because so and so. Partial credits for demonstrating only partial understanding.  -  Am I missing some important aspects of philosophical thinking? Should I emphasize the different parts of an answer in a different way? I suspect my perspective is influenced by fairly extensive mathematics education - is there something particular I should watch out for? Why can't I run two mysqli queries?
