  • JAVA - Download PDF file from Webserver

    - by Augusto Picciani
    I need to download a pdf file from a webserver to my pc and save it locally. I used Httpclient to connect to webserver and get the content body: HttpEntity entity=response.getEntity(); InputStream in=entity.getContent(); String stream = CharStreams.toString(new InputStreamReader(in)); int size=stream.length(); System.out.println("stringa html page LENGTH:"+stream.length()); System.out.println(stream); SaveToFile(stream); Then i save content in a file: //check CRLF (i don't know if i need to to this) String[] fix=stream.split("\r\n"); File file=new File("C:\\Users\\augusto\\Desktop\\progetti web\\test\\test2.pdf"); PrintWriter out = new PrintWriter(new FileWriter(file)); for (int i = 0; i < fix.length; i++) { out.print(fix[i]); out.print("\n"); } out.close(); I also tried to save a String content to file directly: OutputStream out=new FileOutputStream("pathPdfFile"); out.write(stream.getBytes()); out.close(); But the result is always the same: I can open pdf file but i can see white pages only. Does the mistake is around pdf stream and endstream charset encoding? Does pdf content between stream and endStream need to be manipulate in some others way?

  • java annotations - problem with calling a locator class from a Vaadin Project

    - by George
    Hello, I'm not sure how to explain this without writing several pages so I hope the actual code is more expressive. I've made a jar containing multiple annotation declaration similar to the following: @Target(ElementType.PACKAGE) @Retention(RetentionPolicy.RUNTIME) public @interface MarkedPackage { } then I have made a test jar containing several classes in several packages and marked just one package with the above annotation (with package-info.java) like below: @myPackage.MarkedPackage package package.test.jar; this jar had in its build path the jar containing the annotations. then I made a static class that has a method (LoadPlugins) that retrieves a list with all the jars of a directory. Then it searches through the jars for the 'package-info' class and checks if that classes package contains the MarkedPackage annotation. by calling this: if (checkPackageAnnotation(thisClass.getPackage())) where thisClass is the package-info class retrieved via a classloader. and: public static boolean checkPackageAnnotation(AnnotatedElement elem) { System.out.println(elem.getAnnotations().length); if (elem == null || !elem.isAnnotationPresent(MarkedPackage.class)) return false; return true; } the elem.getAnnotatios().length is there for debug purposes. And the problem appears when I call the method from the static class: if I call it from a main function: public class MyMain { public static void main(String[] args){ PluginUtils.LoadPlugins(); } } everything works perfectly it displays '1' from that System.out.println(elem.getAnnotations().length); But if I call it from a button from my Vaadin project: header.addComponent(new Button("CallThat", new Button.ClickListener() { public void buttonClick(ClickEvent event) { PluginUtils.LoadPlugins(); } })); It displays '0' from that System.out.println(elem.getAnnotations().length); Also I should mention that I created the main inside my Vaadin project so it would have the exact same build path and resources. Is there a problem with web applications and that "@Retention(RetentionPolicy.RUNTIME)" ? hope I was clear enough... Hope someone has a solution for me... If you need more information - let me know. Thank you.

  • What is the easiest way to read wav-files using Python [summary]?

    - by Roman
    I want to use Python to access a wav-file and write its content in a form which allows me to analyze it (let's say arrays). I heard that "audiolab" is a suitable tool for that (it transforms numpy arrays into wav and vica versa). I have installed the "audiolab" but I had a problem with the version of numpy (I could not "from numpy.testing import Tester"). I had 1.1.1. version of numpy. I have installed a newer version on numpy (1.4.0). But then I got a new set of errors: Traceback (most recent call last): File "test.py", line 7, in import scikits.audiolab File "/usr/lib/python2.5/site-packages/scikits/audiolab/init.py", line 25, in from pysndfile import formatinfo, sndfile File "/usr/lib/python2.5/site-packages/scikits/audiolab/pysndfile/init.py", line 1, in from _sndfile import Sndfile, Format, available_file_formats, available_encodings File "numpy.pxd", line 30, in scikits.audiolab.pysndfile._sndfile (scikits/audiolab/pysndfile/_sndfile.c:9632) ValueError: numpy.dtype does not appear to be the correct type object I gave up to use audiolab and thought that I can use "wave" package to read in a wav-file. I asked a question about that but people recommended to use scipy instead. OK, I decided to focus on scipy (I have 0.6.0. version). But when I tried to do the following: from scipy.io import wavfile x = wavfile.read('/usr/share/sounds/purple/receive.wav') I get the following: Traceback (most recent call last): File "test3.py", line 4, in <module> from scipy.io import wavfile File "/usr/lib/python2.5/site-packages/scipy/io/__init__.py", line 23, in <module> from numpy.testing import NumpyTest ImportError: cannot import name NumpyTest So, I gave up to use scipy. Can I use just wave package? I do not need much. I just need to have content of wav-file in human readable format and than I will figure out what to do with that.

  • Read a specific range of lines from a file using c

    - by James Joy
    I have the following content in a file: hhasfghgsafjgfhgfhjf gashghfdgdfhgfhjasgfgfhsgfjdg jfshafghgfgfhfsghfgffsjgfj . . . . . startread hajshjsfhajfhjkashfjf hasjgfhgHGASFHGSHF hsafghfsaghgf . . . . . stopread . . . . . . jsfjhfhjgfsjhfgjhsajhdsa jhasjhsdabjhsagshaasgjasdhjk jkdsdsahghjdashjsfahjfsd I need to read the lines from the next line of startread till the previous line of stopread using a c code and store it to a string variable(of course with a \n for every line breaks). How can i achieve this? I have used fgets(line,sizeof(line),file); but it starts reading from the beginning. I don't have the exact line number to start and stop reading since the file is written by another C code. But there are these identifiers startread and stopread to identify whereto start reading. Operating platform is linux. Thanks in advance.

  • Reading in bytes produced by PHP script in Java to create a bitmap

    - by Kareem
    I'm having trouble getting the compressed jpeg image (stored as a blob in my database). here is the snippet of code I use to output the image that I have in my database: if($row = mysql_fetch_array($sql)) { $size = $row['image_size']; $image = $row['image']; if($image == null){ echo "no image!"; } else { header('Content-Type: content/data'); header("Content-length: $size"); echo $image; } } here is the code that I use to read in from the server: URL sizeUrl = new URL(MYURL); URLConnection sizeConn = sizeUrl.openConnection(); // Get The Response BufferedReader sizeRd = new BufferedReader(new InputStreamReader(sizeConn.getInputStream())); String line = ""; while(line.equals("")){ line = sizeRd.readLine(); } int image_size = Integer.parseInt(line); if(image_size == 0){ return null; } URL imageUrl = new URL(MYIMAGEURL); URLConnection imageConn = imageUrl.openConnection(); // Get The Response InputStream imageRd = imageConn.getInputStream(); byte[] bytedata = new byte[image_size]; int read = imageRd.read(bytedata, 0, image_size); Log.e("IMAGEDOWNLOADER", "read "+ read + " amount of bytes"); Log.e("IMAGEDOWNLOADER", "byte data has length " + bytedata.length); Bitmap theImage = BitmapFactory.decodeByteArray(bytedata, 0, image_size); if(theImage == null){ Log.e("IMAGEDOWNLOADER", "the bitmap is null"); } return theImage; My logging shows that everything has the right length, yet theImage is always null. I'm thinking it has to do with my content type. Or maybe the way I'm uploading?

  • Navigating through code with keyboard shortcuts

    - by MarceloRamires
    I'm starting to feel the need to run fastly through code with keyboard shortcuts, to arrive faster where I want to make any changes (avoiding use of mouse or long times holding [up], [left], [right] and [down]). I'm already using some: [home] - first position in current line [end] - last position in current line [ctrl] + [home] - first line of the entire code [ctrl] + [end] - last line of the entire code [pageup] - same vertical position, one screen above [pagedown] - same vertical position, one screen below [ctrl] + [pageup] - first line in current screen [ctrl] + [end] - last line in current screen [ctrl] + [left/right] - skipping word per word What have you got ? I use Visual Studio. (but I'm open to any answer, as I maybe can use others soon) obs: I've searched through stackoverflow and didn't find a nice question with this content, nor a list of keyboard code searching. If it's repeated, I'm sorry for not finding it, I'm here in my best intentions. This question is NOT about any shortcuts, and not only about visual studio, it's about running through code with shortcuts. Answers that suit the question so far: [Ctrl] + [-] - jumps to last cursor position [Ctrl] + [F3] - Jumps to next occurance of the word the curson is in [Shift] + [F3] - Same as the above, backwards. [F12] - Goes to definition of method/variable the cursor is in [Ctrl] + [ ] ] - Jumps to matching brace and select I'll ad more as there are answers.

  • IF-block brackets: best practice

    - by MasterPeter
    I am preparing a short tutorial for level 1 uni students learning JavaScript basics. The task is to validate a phone number. The number must not contain non-digits and must be 14 digits long or less. The following code excerpt is what I came up with and I would like to make it as readable as possible. if ( //set of rules for invalid phone number phoneNumber.length == 0 //empty || phoneNumber.length > 14 //too long || /\D/.test(phoneNumber) //contains non-digits ) { setMessageText(invalid); } else { setMessageText(valid); } A simple question I can not quite answer myself and would like to hear your opinions on: How to position the surrounding (outermost) brackets? It's hard to see the difference between a normal and a curly bracket. Do you usually put the last ) on the same line as the last condition? Do you keep the first opening ( on a line by itself? Do you wrap each individual sub-condition in brackets too? Do you align horizontally the first ( with the last ), or do you place the last ) in the same column as the if? Do you keep ) { on a separate line or you place the last ) on the same line with the last sub-condition and then place the opening { on a new line? Or do you just put the ) { on the same line as the last sub-condition? Community wiki.

  • How to handle image/gif type response on client side using GWT

    - by user200340
    Hi all, I have a question about how to handle image/gif type response on client side, any suggestion will be great. There is a service which responds for retrieving image (only one each time at the moment) from database. The code is something like, JDBC Connection Construct MYSQL query. Execute query If has ResultSet, retrieve first one { //save image into Blob image, “img” is the only entity in the image table. image = rs.getBlob("img"); } response.setContentType("image/gif"); //set response type InputStream in = image.getBinaryStream(); //output Blob image to InputStream int bufferSize = 1024; //buffer size byte[] buffer = new byte[bufferSize]; //initial buffer int length =0; //read length data from inputstream and store into buffer while ((length = in.read(buffer)) != -1) { out.write(buffer, 0, length); //write into ServletOutputStream } in.close(); out.flush(); //write out The code on client side .... imgform.setAction(GWT.getModuleBaseURL() + "serviceexample/ImgRetrieve"); .... ClickListener { OnClick, then imgform.submit(); } formHandler { onSubmit, form validation onSubmitComplete ??????? //handle response, and display image **Here is my question, i had tried Image img = new Image(GWT.getHostPageBaseURL() +"serviceexample/ImgRetrieve"); mg.setSize("300", "300"); imgpanel.add(img); but i only got a non-displayed image with 300X300 size.** } So, how should i handle the responde in this case? Thanks,

  • Python: Most efficient way to concatenate and rearrange files

    - by user300890
    Hi, I am reading from several files, each file is divided into 2 pieces, first a header section of a few thousand lines followed by a body of a few thousand. My problem is I need to concatenate these files into one file where all the headers are on the top followed by the body. Currently I am using two loops; one to pull out all the headers and write them, and the second to write the body of each file (I also include a tmp_count variable to limit the number of lines to be loading into memory before dumping to file). This is pretty slow - about 6min for 13gb file. Can anyone tell me how to optimize this or if there is a faster way to do this in python ? Thanks! Here is my code: def cat_files_sam(final_file_name,work_directory_master,file_count): final_file = open(final_file_name,"w") if len(file_count) > 1: file_count=sort_output_files(file_count) # only for @ headers for bowtie_file in file_count: #print bowtie_file tmp_list = [] tmp_count = 0 for line in open(os.path.join(work_directory_master,bowtie_file)): if line.startswith("@"): if tmp_count == 1000000: final_file.writelines(tmp_list) tmp_list = [] tmp_count = 0 tmp_list.append(line) tmp_count += 1 else: final_file.writelines(tmp_list) break for bowtie_file in file_count: #print bowtie_file tmp_list = [] tmp_count = 0 for line in open(os.path.join(work_directory_master,bowtie_file)): if line.startswith("@"): continue if tmp_count == 1000000: final_file.writelines(tmp_list) tmp_list = [] tmp_count = 0 tmp_list.append(line) tmp_count += 1 final_file.writelines(tmp_list) final_file.close()

  • jQuery ajax post of jpg image to .net webservice. Image results corrupted

    - by sosergio
    I have a phonegap jquery app that opens the camera and take a picture. I then POST this picture to a .net webservice, wich I've coded. I can't use phonegap FileTransfer because such isn't supported by Bada os, wich is a requirement. I believe I've successfully loaded the image from phonegap FileSystem API, I've attached it into an .ajax type:post, I've even received it from .net side, but when .net save the image into the server, the image results corrupted. It seems to me that two sides of the communication have different data type. Has anyone experience in this? Any help will be appreciated. This is my code: //PHONEGAP CAMERA ACCESS (summed up) navigator.camera.getPicture(onGetPictureSuccess, onGetPictureFail, { quality: 50, destinationType:Camera.DestinationType.FILE_URI }); window.resolveLocalFileSystemURI(imageURI, onResolveFileSystemURISuccess, onResolveFileSystemURIError); fileEntry.file(gotFileSuccess, gotFileError); new FileReader().readAsDataURL(file); //UPLOAD FILE function onDataReadSuccess(evt) { var image_data = evt.target.result; var filename = unique_id(); var filext = "jpg"; $.ajax({ type : 'POST', url : SERVICE_BASE_URL+"/fotos/"+filename+"?ext="+filext, cache: false, timeout: 100000, processData: false, data: image_data, contentType: 'image/jpeg', success : function(data) { console.log("Data Uploaded with success. Message: "+ data); $.mobile.hidePageLoadingMsg(); $.mobile.changePage("ok.html"); } }); } On my .net Web Service this is the method that gets invoked: public string FotoSave(string filename, string extension, Stream fileContent) { string filePath = HttpContext.Current.Server.MapPath("~/foto_data/") + "\\" + filename; FileStream writeStream = new FileStream(filePath, FileMode.OpenOrCreate, FileAccess.Write); int Length = 256; Byte[] buffer = new Byte[Length]; int bytesRead = readStream.Read(buffer, 0, Length); // write the required bytes while (bytesRead > 0) { writeStream.Write(buffer, 0, bytesRead); bytesRead = readStream.Read(buffer, 0, Length); } readStream.Close(); writeStream.Close(); }

  • Run command with space characters in bash script

    - by ??iu
    I have a file that contains a list of files: 02 of Clubs.eps 02 of Diamonds.eps 02 of Hearts.eps 02 of Spades.eps ... I am attempting to mass-convert these to png format in several sizes. The script I am using to do this is: while read -r line do for i in 80 35 200 do convert $(sed 's/ /\\ /g' <<< Cards/${line}) -size ${i}x${i} ../img/card/$(basename $(tr ' ' '_' <<< ${line} | tr '[A-Z]' '[a-z]') .eps)_${i}.png; done done < card_list.txt However, this doesn't work, apparently trying to split on each word, resulting in the following error output: convert: unable to open image `Cards/02\': No such file or directory @ error/blob.c/OpenBlob/2514. convert: no decode delegate for this image format `Cards/02\' @ error/constitute.c/ReadImage/532. convert: unable to open image `of\': No such file or directory @ error/blob.c/OpenBlob/2514. convert: no decode delegate for this image format `of\' @ error/constitute.c/ReadImage/532. convert: unable to open image `Clubs.eps': No such file or directory @ error/blob.c/OpenBlob/2514. If I change the convert to an echo the result looks right and if I copy a line and run it myself in the shell it works fine: convert Cards/02\ of\ Clubs.eps -size 80x80 ../img/card/02_of_clubs_80.png convert Cards/02\ of\ Clubs.eps -size 35x35 ../img/card/02_of_clubs_35.png convert Cards/02\ of\ Clubs.eps -size 200x200 ../img/card/02_of_clubs_200.png convert Cards/02\ of\ Diamonds.eps -size 80x80 ../img/card/02_of_diamonds_80.png convert Cards/02\ of\ Diamonds.eps -size 35x35 ../img/card/02_of_diamonds_35.png convert Cards/02\ of\ Diamonds.eps -size 200x200 ../img/card/02_of_diamonds_200.png convert Cards/02\ of\ Hearts.eps -size 80x80 ../img/card/02_of_hearts_80.png convert Cards/02\ of\ Hearts.eps -size 35x35 ../img/card/02_of_hearts_35.png convert Cards/02\ of\ Hearts.eps -size 200x200 ../img/card/02_of_hearts_200.png convert Cards/02\ of\ Spades.eps -size 80x80 ../img/card/02_of_spades_80.png UPDATE: Just adding quotes (see below) has the same result as the above, where I had been using sed to add backslashes convert '"'Cards/${line}'"' -size ${i}x${i} ../img/card/$(basename $(tr ' ' '_' <<< ${line} | tr '[A-Z]' '[a-z]') .eps)_${i}.png; I've tried both double and single quotes

  • W3 xHTML Validation Errors on jQuery code!

    - by Chris
    I have some jQuery code that, without it in the document it passes validation fine, but with it in it causes errors. The code in question is here: $.ajax({ type: "GET", url: "data.xml", dataType: "xml", success: function(xml) { //Update error info errors = $(xml).find("Errors").find("*").filter(function () { return $(this).children().length === 0; }); if (errors.length == 0) { statuscontent = "<img src='/web/resources/graphics/accept.png' alt='' /> System OK"; } else { statuscontent = "<img src='/web/resources/graphics/exclamation.png' alt='' /> "+errors.length+" System error"+(errors.length>1?"s":""); } $("#top-bar-systemstatus a").html(statuscontent); //Update timestamp $("#top-bar-timestamp").html($(xml).find("Timestamp").text()); //Update storename $("#top-bar-storename").html("Store: "+$(xml).find("StoreName").text()); } }); There are loads of other jQuery code on the page which all works fine and causes no errors so I cannot quite understand what is wrong with this. The page isn't "live" so cannot provide a link to it unfortunately. The error it lists is document type does not allow element "img" here And the line of code it points to is here: statuscontent = "<img src='/web/resources/graphics/accept.png' alt='' /> System OK"; It also has an issue with the next assignment to statuscontent

  • Reduce white space between lines of text

    I am creating a webpage (first time) and i'm following as much of the CSS rules and tags as I can. However, I ran into a problem with white space. I've underlined the first line of text but now the second line seems to have drifted below. Is there a way to make it a bit more snug, i'd like the second line of text to be just below the above line. body,td,th { color: #000000; } body { margin: 0; padding: 0; padding-top: 6px; text-align: center; background-color: #FFFFFF; } #centered { width: 800px; /* set to desired width in px or percent */ text-align: left; /* optionally you could use "justified" */ border: 0px; /* Changing this value will add lines around the centered area */ padding: 0; margin: 0 auto; } .style3 { font-size: 32pt; color: #666666; margin-left: 0px; border-bottom: 3px double; } .style5 { margin-left: 390px; font-size: 32pt; color: #CCCCCC; } --> </style></head> <div id="centered"> <body> <p class="style3">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;FIRST LINE OF TEXT</p> <p class="style5">INDENTED SECOND LINE</p> </body> </div> </body> </html>

  • Gdata JavaScript Authsub continues redirect

    - by Krustal
    I am using the JavaScript Google Data API and having issues getting the AuthSub script to work correctly. This is my script currently: google.load('gdata', '1'); function getCookie(c_name){ if(document.cookie.length>0){ c_start=document.cookie.indexOf(c_name + "="); if(c_start!=-1){ c_start=c_start + c_name.length+1; c_end=document.cookie.indexOf(";",c_start); if(c_end==-1) c_end=document.cookie.length; return unescape(document.cookie.substring(c_start, c_end)); } } return ""; } function main(){ var scope = 'http://www.google.com/calendar/feeds/'; if(!google.accounts.user.checkLogin(scope)){ google.accounts.user.login(); } else { /* * Retrieve all calendars */ // Create the calendar service object var calendarService = new google.gdata.calendar.CalendarService('GoogleInc-jsguide-1.0'); // The default "allcalendars" feed is used to retrieve a list of all // calendars (primary, secondary and subscribed) of the logged-in user var feedUri = 'http://www.google.com/calendar/feeds/default/allcalendars/full'; // The callback method that will be called when getAllCalendarsFeed() returns feed data var callback = function(result) { // Obtain the array of CalendarEntry var entries = result.feed.entry; //for (var i = 0; i < entries.length; i++) { var calendarEntry = entries[0]; var calendarTitle = calendarEntry.getTitle().getText(); alert('Calendar title = ' + calendarTitle); //} } // Error handler to be invoked when getAllCalendarsFeed() produces an error var handleError = function(error) { alert(error); } // Submit the request using the calendar service object calendarService.getAllCalendarsFeed(feedUri, callback, handleError); } } google.setOnLoadCallback(main); However when I run this the page redirects me to the authentication page. After I authenticate it send me back to my page and then quickly sends me back to the authenticate page again. I've included alerts to check if the token is being set and it doesn't seem to be working. Has anyone has this problem?

  • Most efficient method of detecting/monitoring DOM changes?

    - by Graza
    I need an efficient mechanism for detecting changes to the DOM. Preferably cross-browser, but if there's any efficient means which are not cross browser, I can implement these with a fail-safe cross browser method. In particular, I need to detect changes that would affect the text on a page, so any new, removed or modified elements, or changes to inner text (innerHTML) would be required. I don't have control over the changes being made (they could be due to 3rd party javascript includes, etc), so it can't be approached from this angle - I need to "monitor" for changes somehow. Currently I've implemented a "quick'n'dirty" method which checks body.innerHTML.length at intervals. This won't of course detect changes which result in the same length being returned, but in this case is "good enough" - the chances of this happening are extremely slim, and in this project, failing to detect a change won't result in lost data. The problem with body.innerHTML.length is that it's expensive. It can take between 1 and 5 milliseconds on a fast browser, and this can bog things down a lot - I'm also dealing with a large-ish number of iframes and it all adds up. I'm pretty sure the expensiveness of doing this is because the innerHTML text is not stored statically by browsers, and needs to be calculated from the DOM every time it is read. The types of answers I am looking for are anything from the "precise" (for example event) to the "good enough" - perhaps something as "quick'n'dirty" as the innerHTML.length method, but that executes faster.

  • why can't i bind ipv6 socket to a linklocal address

  • jQuery('body').text() gives different answers in different browsers

    - by Charles Anderson
    My HTML looks like this: <html> <head> <title>Test</title> <script type="text/javascript" src="jQuery.js"></script> <script type="text/javascript"> function init() { var text = jQuery('body').text(); alert('length = ' + text.length); } </script> </head> <body onload="init()">0123456789</body> </html> When I load this in Firefox, the length is reported as 10. However, in Chrome it's 11 because it thinks there's a linefeed after the '9'. In IE it's also 11, but the last character is an escape. Meanwhile, Opera thinks there are 12 characters, with the last two being CR LF. If I change the body element to include a span: <body onload="init()"><span>0123456789</span></body> and the jQuery call to: var text = jQuery('body span').text(); then all the browsers agree that the length is 10. Clearly it's the body element that's causing the issue, but can anyone explain exactly why this is happening? I'm particularly surprised because the excellent jQuery is normally browser-independent.

  • Project Euler #14 and memoization in Clojure

    - by dbyrne
    As a neophyte clojurian, it was recommended to me that I go through the Project Euler problems as a way to learn the language. Its definitely a great way to improve your skills and gain confidence. I just finished up my answer to problem #14. It works fine, but to get it running efficiently I had to implement some memoization. I couldn't use the prepackaged memoize function because of the way my code was structured, and I think it was a good experience to roll my own anyways. My question is if there is a good way to encapsulate my cache within the function itself, or if I have to define an external cache like I have done. Also, any tips to make my code more idiomatic would be appreciated. (use 'clojure.test) (def mem (atom {})) (with-test (defn chain-length ([x] (chain-length x x 0)) ([start-val x c] (if-let [e (last(find @mem x))] (let [ret (+ c e)] (swap! mem assoc start-val ret) ret) (if (<= x 1) (let [ret (+ c 1)] (swap! mem assoc start-val ret) ret) (if (even? x) (recur start-val (/ x 2) (+ c 1)) (recur start-val (+ 1 (* x 3)) (+ c 1))))))) (is (= 10 (chain-length 13)))) (with-test (defn longest-chain ([] (longest-chain 2 0 0)) ([c max start-num] (if (>= c 1000000) start-num (let [l (chain-length c)] (if (> l max) (recur (+ 1 c) l c) (recur (+ 1 c) max start-num)))))) (is (= 837799 (longest-chain))))
