How do I determine the total size of a directory (folder) from the command line?
The command du "summarizes disk usage of each FILE, recursively for directories," e.g., du -hs /path/to/directory -h is to get the numbers "human readable", e.g. get 140M instead of 143260 (size in KBytes) -s is for summary (otherwise you'll get not only the size of the folder but also for everything in the folder separately) As you're using -h you can sort the human readable values using du -h | sort -h The -h flag on sort will consider "Human Readable" size values. If want to avoid recursively listing all files and directories, you can supply the --max-depth parameter to limit how many items are displayed. Most commonly, --max-depth=1 du -h --max-depth=1 /path/to/directory   How do I determine the total size of a directory (folder) from the command line? Is there a simple command to display the total aggregate size (disk usage) of all files in a directory (folder)? I have tried these, and they don't do what I want: ls -l, which only displays the ... https://askubuntu.com/questions/1224/how-do-i-determine-the-total-size-of-a-directory-folder-from-the-command-line

Can I run multiple Elasticsearch instances in one server?
Yes and I did that recently with my laptop for experimentation with things that I would like to do with ES Cluster. This setup simplifies my environment, instead of using docker or using multiple machines/VMs/EC2 instances. You can download and use the .tar.gz file recommended above, and then you can do one of the following options option 1 - untar the file into two directories: es-01, es-02 then update the config file in each node option 2 - untar the file into one directory: es-instance, copy the config directory to another location with something like path/to/es-01/config, path/to/es-02/config then create a script to launch elasticsearch from the same binary location (which is es-instance) but use different config location (one for es-01/config, one for es-02/config) You need to update the following parameters in config/elasticsearch.yml file to separate one node from the other. cluster.name node.name path.data path.logs http.port   Can I run multiple Elasticsearch instances in one server?

Jsoup - Working with URLs
Following example will showcase methods which can provide relative as well as absolute URLs present in the html page. Syntax String url = "http://www.tutorialspoint.com/"; Document document = Jsoup.connect(url).get(); Element link = document.select("a").first(); System.out.println("Relative Link: " + link.attr("href")); System.out.println("Absolute Link: " + link.attr("abs:href")); System.out.println("Absolute Link: " + link.absUrl("href")); Where document − document object represents the HTML DOM. Jsoup − main class to connect to a url and get the html content. link − Element object represent the html node element representing anchor tag. link.attr("href") − provides the value of href present in anchor tag. It may be relative or absolute. link.attr("abs:href") − provides the absolute url after resolving against the document's base URI. link.absUrl("href") − provides the absolute url after resolving against the document's base URI. Description Element object represent a dom elment and provides methods to get relative as well as absolute URLs present in the html page.

Remove Trailing Slash in NGINX
Sometimes NGINX may show trailing slash in website URLs. Here’s how to remove trailing slash in NGINX to make your URLs look more intuitive.   Remove trailing slash in NGINX Here are the steps to remove trailing slash in NGINX.   1. Open NGINX configuration file Open terminal and run the following command to open NGINX server configuration file. $ sudo vi /etc/nginx/nginx.conf If you have configured separate virtual hosts for your website (e.g www.example.com), such as /etc/nginx/sites-enabled/website.conf then open its configuration with the following command $ sudo vi /etc/nginx/sites-enabled/website.conf 2. Remove trailing slash Add the following rewrite rule in server block as shown in bold. Replace example.com below with your domain name server { listen 80; server_name example.com; rewrite ^/(.*)/$ /$1 permanent; } In the above code, the rewrite statement will redirect all URLs to those without trailing slash. If you want to remove trailing slash from only a specific URL (e.g /product/) then update the rewrite statement as shown below. server { listen 80; server_name mydomain.com; rewrite ^/product/$ /product permanent; }   * You can also use this method. Remove the trailing slash from all paths except mypath. location ~ ^/mypath(.*) { try_files $uri @tomcat; } location ~ (?<no_slash>.*)/$ { return 301 $no_slash; } ... location / { try_files $uri @tomcat; } location @tomcat { ... }   3. Restart NGINX Server Run the following command to check syntax of your updated config file. $ sudo nginx -t If there are no errors, run the following command to restart NGINX server. $ sudo service nginx reload #debian/ubuntu $ systemctl restart nginx #redhat/centos

Counting Heads
There are more ideas to the page in this auspicious debut novel than many science fiction novels have in their entirety. In its twenty-second century world the world's survived the mega-terrorism of "the Outrage" that occurred in the 2060s and is now wondrously nanotechnical. Production is unneeded as any product can be extruded from recycled materials. Lifespans extend for hundreds of rejuvenated years. Nanoprocessors residing in one's body link to personal AI "valets" (later "mentars") that amplify one's life a myriad ways. Skilled trades -- like security and nursing -- are filled by an underclass of specialized clones, Robot "arbeitors" perform lowlier tasks. The world is so perfect there are just too many people for it. Jobs are scarce and money, for most, is scarcer. Core character Samson Harger, a packaging artiste, marries fellow "aff" -- "affluents" run the world with a pettiness and ruthlessness akin to medieval royalty -- Eleanor Starke, a high-powered corporate prosecutor who becomes one of the most influential people in the world. Just as they are granted the nearly unheard of privilege to have a child, their marriage is torn apart when Harger is misidentified by Homeland Command as a criminal and consequently "seared." Searing deprives Harger of the now-common (as long as one can afford it) lifespan of hundreds of years. He is left with perhaps four decades of life as a smelly social outcast. The story skips ahead 40 years and Starke, pursuing a colonization project to help relieve the masses, is assassinated in the crash of her space yacht, but daughter Ellen survives -- at least her decapitated head does. Ellen can be rejuvenated -- but only if her head avoids those who want her dead. The back story of Harger's seared life and subplots weaving around the goal of saving Ellen show more of the fascinating aspects of Marusek's dystopia and its denizens. Marusek evokes an impelling sense of wonder with an awesomely imaginative and all-too-believable future chock full of nifty details while allowing his characters to compel the novel. Counting Heads is a marvelous must-read from an author who must be noted as an important new voice in science fiction. -- (in CFQ Jan/Feb 2006 issue)   xwidget_78_Counting Heads

Play Dead
xwidget_77_Play Dead   There's a lot of style to Play Dead and some will find a fast-paced, entertaining read. But... Michael Arnzen is a talented, intelligent writer. His flair and potential was first noted with his first novel Grave Markings (1994). Academia intervened and the fiction slowed as he completed graduate degrees and became a college professor. He re-emerged a few years back with poetry and short fiction. A trademark of Arnzen's recent work is its cleverness. With 100 Jolts: Shockingly Short Stories, for example, Arnzen applied the "literary" device of flash fiction exclusively to horror so as to prove his stated point that "[h]orror is the genre of the jolt, the shock, the spark." Each short-short story was intended to elicit an immediate reaction from the reader. It was an interesting experiment. Some of the stories succeed as stories, many of them don't. I applaud the experiment and delight in the ingenuity. It may even stand as a pioneering effort. But, as a story collection, it is not a complete success -- at least by my definition. [In some ways, 100 Jolts is an expression of the 1984 Stephen King statement in Danse Macabre that is usually abbreviated to, "I'll go for the gross-out." A fuller rendition of that quotation is: "I recognize terror as the finest emotion... and so I will try to terrorize the reader. But if I cannot terrify him/her, I will try to horrify; and if I cannot horrify, I'll go for the gross-out. I'm not proud." I wonder if, more than twenty years on, Stephen King still feels this way? I can't speak for King, but, to me, horror is much more than "shock." Nor can I agree with Arnzen's belief (also from his introduction), "Horror stories conflict is always about life and death, but death...always comes as a surprise. The climax of a horror tale is almost unilaterally a killing blow, catching someone or something unaware."] Back to the point -- Arnzen is a clever writer and 100 Jolts is a clever experiment and worth reading, but it is not a great collection. Play Dead, his long-awaited second novel, is also clever, but it is not a great novel. Play Dead's cleverness is displayed in several ways. The most obvious: It's about card playing and is divided into four parts, one for each suite of the deck. It has 52 chapters, each representing a card of the deck. Another example: A character named Axe is a cook. He gets "the axe" at work. A character thinks, "Axe got the axe." A couple of paragraphs later the same character thinks about how he must "bury the hatchet" and make peace. On the next page the character finds Axe in a dumpster and decides he has to bury Axe and thinks: "Had to bury the hatchet. Literally." This is a book in which you know what will happen next if a character says, "You bet your life." And, of course, there is a great deal of wordplay with card and gambling-related terms. The plot revolves around Johnny Frieze, a none-too-bright gambler down on his luck. Johnny sees life as sheer chance and pure luck. A bad guy, Nebo, and his henchman, Winston, are setting up a game of "Butcher Boy" and each of four players must make up a suite of the deck by taking Polaroids that "capture life." This are then turned into cards. Extra points are added for creativity. (I'm sure there is no need to translate what "capturing life" means.) Once the deck is complete the four players are to play to the death with the single survivor walking away with a million bucks (and a lot of bad karma). Why? We are, at first, offered an obvious extolling of cliches by Nebo: "Playing people...Life is a game...Without the possibility of loss there is no game...This is my game...." We later get a possible supernatural tie-in involving "prophecy cards" and the power of capital "F" Fate. Johnny becomes a player and is to provide the spades. Johnny's fellow players are Shorty, Ferret, and Preacher. Like most fictional characters with unfortunate nicknames, these guys are homicidal maniacs and immediately go about "capturing life" with great psychopathological fervor. Johnny, however, tries to cheat fate and Nebo. There are two female characters. Gin is Johnny's love interest and, therefore, endangered. The first paragraph of their first love scene begins: "Her lips tested like warm bread..." and ends "She tasted like a warm worm of menthol scotch." She's a tasty girl. Violet is an old slot machine queen. (We are never sure how old. A hint comes from the end and places her over 65, maybe 70.) Violet reads the Tarot and talks about fate-with-a-small-"f". Violet has some odd quirks for someone who evidently believes in her cards -- like keeping her deck bound with a rubber band and calling card that sure sounds like the Knight of Swords the King of Swords. I'm reviewing from an Advanced Review Copy, so maybe the knight/king will change, but, the point is: for novel in which Tarot plays a role, it seems a bit under-researched. There's a penultimate card game (these cards are well-researched and far more convincing, even if you are not a veteran poker player) and a clever trick ending that may pull the rug out from under the entire book for you. Play Dead lacks the sort of authenticity that is hard to define, but notable when missing. Instead of living, breathing, right-out-of-Vegas characters we get varying degrees of characterizations and no real feel for Vegas's unique reality. Any environment demands a response and Vegas demands a great deal. A better sense of place might also have provided more psychological nuance and more atmosphere. Oh we are told Vegas is "heaven right smack dab in the middle of hell" and that that it offers the tourists "one big excuse to be a loser for a day, and be damned proud of throwing their money away in a perverse ritual as moronic as religious fasting" -- but we feel neither the damnation of the flames nor the artificial salvation of air conditioning. Likewise the living hell of addiction is an underlying metaphor, but the reader is unlikely to feel any of that particular hell either. As I said before the, some readers will find the novel be a fast-paced, entertaining read. Maybe it will be "good" for them. Not all novels are, after all, "great." But this one could have been somewhat greater and shown more than the potential the author is already known to possess. Or, perhaps, Arnzen's talent might have been better served with fresh material. (Play Dead's first incarnation was as his Master's thesis.) Whatever the case, I look forward to his future work. (from Cemetery Dance #53)
