20,287,627 | 0 | <p>Without seeing the import statement that you tried, I am not 100% sure about why is that happening... But perhaps the reason is that you are using the default delimiter for fields, which is precisely a comma, so if you want to keep it, you should use a different delimiter, like for example:</p> <pre><code>--fields-terminated-by \t </code></pre> <p>Another option would be to use <code>--enclosed-by '\"'</code>, and it would look like "sami, ramesh".</p> <p>Hope that helps!

21,302,600 | 0 | <p><strong>Neither are safe</strong>. Please avoid flashy <code>max</code> macro implementations that rely on non-standard C extensions like <em>expression statements</em> which will give you all sort of headaches if you ever have to port your code to a different platform. Doing my best to present this answer from becoming a rant, the <code>max</code> macro is, in my opinion, one of the worst things in C standard libraries due to its potential side-effects. In times past, I've #<code>undef</code>ed <code>max</code> just to be on the safe side.</p> <p>Your're better off coding the second macro <code>maxint</code> as a function as it has all the drawbacks of macros (e.g. can't debug easily, instantiated variables clashing with locals) but none of the benefits (e.g. genericisation).</p> <p><strong>Alternatives</strong>:</p> <p>My favourite: use the ternary inline: <code>a > b ? a : b</code> where you can drop the parentheses to taste since you know exactly what is going on. It will also be faster than macros that try to be safe by taking value copies.</p> <p>Build your own functions. Consider defining <code>max</code> for integral types and <code>fmax</code> for floating point. There is already a precedent here with <code>abs</code> and <code>fabs</code>.</p> |

19,014,834 | 0 | Is it possible to associate an instance of an object with one file while it's being mapped by a map-only mapred Job? <p>I want to use a HashSet that exists/works against one file while it's being mapped, and then is reset/recreated when the next file is being mapped. I have modified TextInputFormat to override isSplitable to return false, so that the file is not split up and is processed as a whole by Mappers. Is it possible to do something like this? Or is there another way to do fewer writes to the Accumulo table?</p> <p>Let me start out with I do not believe I want a global variable. I just want to ensure uniqueness and thus write fewer mutations to my Accumulo table.</p> <p>My project is to convert the functionality of the Index.java file from the shard example from a linear accumulo client program to one that uses mapreduce functionality, while still creating the same table in Accumulo. It needs to be mapreduce because that's the buzzword, and in essence it would run faster than a linear program against terabytes of data.</p> <p>Here is the Index code for reference: <a href="http://grepcode.com/file/repo1.maven.org/maven2/org.apache.accumulo/examples-simple/1.4.0/org/apache/accumulo/examples/simple/shard/Index.java" rel="nofollow">http://grepcode.com/file/repo1.maven.org/maven2/org.apache.accumulo/examples-simple/1.4.0/org/apache/accumulo/examples/simple/shard/Index.java</a></p> <p>This program uses a BatchWriter to write Mutations to Accumulo and does it on a per file basis. To ensure it doesn't write more mutations than necessary and to ensure uniqueness (though I do believe Accumulo eventually merges same keys through compaction), Index.java has a HashSet that is used to determine if a word has been run across before. This is all relatively simple to understand.</p> <p>Moving to a map-only mapreduce job is more complex.</p> <p>This was my attempt at mapping, which seems to kinda work from the partial output I've seen the Accumulo table, but runs really really slow compared to the linear program Index.java</p> <pre><code>public static class MapClass extends Mapper<LongWritable,Text,Text,Mutation> { private HashSet<String> tokensSeen = new HashSet<String>(); @Override public void map(LongWritable key, Text value, Context output) throws IOException { FileSplit fileSplit = (FileSplit)output.getInputSplit(); System.out.println("FilePath " + fileSplit.getPath().toString()); String filePath = fileSplit.getPath().toString(); filePath = filePath.replace("unprocessed", "processed"); String[] words = value.toString().split("\\W+"); for (String word : words) { Mutation mutation = new Mutation(genPartition(filePath.hashCode() % 10)); word = word.toLowerCase(); if(!tokensSeen.contains(word)) { tokensSeen.add(word); mutation.put(new Text(word), new Text(filePath), new Value(new byte[0])); } try { output.write(null, mutation); } catch (InterruptedException e) { e.printStackTrace(); } } } } </code></pre> <p><strong>And the slow problem might be the fact that I'm running all of this on a test instance, a single-node instance of Hadoop with ZooKeeper and Accumulo on top.</strong> If that's the case, I just need to find a solution for uniqueness.</p> <p>Any help or advice provided is greatly appreciated.</p> |

1,984,966 | 0 | <p>A lot of people underestimate the performance of java. I was once curious about this as well and wrote a simple program in java and then an equivalent in c (not much more than doing some operation with a for loop and a massive array). I don't recall exact figures, but I do know that java beat out c when the c program was not compiled with any optimization flags (under gcc). As expected, c pulled ahead when I finally compiled it with aggressive optimization. To be honest, it wasn't a scientific experiment by any means, but it did give me a baseline of knowing just where java stood.</p> <p>Of course, java probably falls further behind when you start doing things that require system calls. Though, I have seen 100MB/s read performance with disks and network with java programs running on modest hardware. Not sure what that says exactly, but it does indicate to me that it's good enough for pretty much anything I'll need it for.</p> <p>As for threads, if your java program creates 2 threads, then you have 2 <em>real</em> threads.</p> |

Here is my dropdown form code, note it still has the submit button that worked before I added :onchange:</p> <pre><code> <% form_tag('switch_car', :method => :put, :remote => true) do %> <div class="field"> <label>Car Name:</label> <%= select_tag(:id, options_from_collection_for_select(active_cars, "id", "name"), :onchange => ("$('switch_car').submit()"))%><%= submit_tag "Switch Car" %> </div> <% end %> </code></pre> <p>Here is the HTML generated:</p> <pre><code><form accept-charset="UTF-8" action="switch_car" data-remote="true" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" /><input name="_method" type="hidden" value="put" /><input name="authenticity_token" type="hidden" value="PEbdqAoiik37lcoP4+v+dakpYxdpMkSm7Ub8eZpdF9I=" /></div><div class="field"> <label>Car Name:</label> <select id="id" name="id" onchange="$('switch_car').submit()"><option value="9">Truck</option> <option value="10">Car</option></select><input name="commit" type="submit" value="Switch Car" /> </div> </code></pre> <p>Thanks in advance for any help. </p> |

That is the version of my simplified code:</p> <pre><code>#include <graphics.h> int main() { initwindow(100, 100); while(true) { if (GetAsyncKeyState(VK_RETURN)) //wait for user to press "Enter" break; //do other stuff } getch(); //this is just skipped return 0; } </code></pre> <p>I think I need to clean the input buffer before using getch().

23,986,330 | 0 | <p><strong>Quick answer</strong> - both operating systems have features for safely unmounting the drive. An unmounted drive can be snapshotted without fear of corruption.</p> <p><strong>Long answer</strong> An EBS snapshot is point-in-time and differential (it does not "copy" your data per-se), so as long as your drive is in a consistent and restorable state when it begins, you'll avoid the corruption (since the snapshot is atomic).</p> <p>As you have implied, whatever state the whole drive is in when it starts, that's what your snapshot image will be when it is restored (if you snapshot while you are half-way done writing a file, then, by-golly, that file will be half-written when you restore).</p> <p>For both Linux and Windows, a consistent state can be this can be acheived by unmounting the drive. This will guarantee that your buffers are flushed to disk and no writes can occur. In both linux and windows there are commands to list which processes are using the drive; once you have stopped those processes or otherwise gotten them to stop marking the drive for use (different for each program/service), you can unmount. In windows, this is very easy by setting your drive as a "removable drive" and then using the "safely remove hardware" feature to unmount. In linux, you can unmount with the "umount" command.</p> <p>There are other sneakier ways, but the above is pretty universal.</p> <p>So assuming you get to a restorable state before you begin, you can resume using your drive as soon as the snapshot starts (you do not need to wait for the snapshot completes before you unlock (or remount) and resume use). At that point you can remount the volume.</p> <p><strong>How AWS snapshot works:</strong></p> <p>Your volume and the snapshot is just a set of pointers, when you take a snapshot, you just diverge any blocks that you write to from that point forward; they are effectively new blocks associated with the volume, and the old blocks at that logical place in the volume are left alone so that the snapshot stays the same logically.</p> <p>This is also why subsequent snapshots will tend to go faster (they are differential).</p> <p><a href="http://harish11g.blogspot.com/2013/04/understanding-Amazon-Elastic-block-store-EBS-snapshots.html" rel="nofollow">http://harish11g.blogspot.com/2013/04/understanding-Amazon-Elastic-block-store-EBS-snapshots.html</a></p> |
24,392,492 | 0 | VMWare vs Azure virtual machines <p>I searched the internet but couldnt find an answer. I know that VMWare gives you a true full virtual machine with a assigned NIC card where Azure virtual machine which is connected through Remote Desktop does not do full virtual. Is full virtual the correct terminology used to describe this or am I wrong?</p> <p>The reason this came up is because I have both environments to play with at work and have multiple customers with different vpn setup. I've noticed that if split tunneling disabled, I cannot use Azure virtual machine and would have to setup on VMWare unless I use something like TeamViewer to connect into the Azure virtual machine.</p> <p>One of my customer (customer A), blocks all traffic after the VPN is established. This includes RDP and HTTP, the only way for this to work is to install a virtual machine on VMware and use vSphere to connect in. </p> <p>My last question, is it possible to get this one customer A working on Azure? My management team wants the IT shop to be all Microsoft so that means they dont want to use VMware anymore. I've tried using TeamViewer but after connecting to VPN (Cisco Anyconect) the connection to TeamViewer gets disconnected because it runs on 80 HTTP and 443 HTTPS. Any work around on Azure that anyone would like to share? Thanks!</p> |

18,443,350 | 0 | <p>The denormalization is in the dimension tables in a star schema: E. g. in a product table, you explicitly have many columns like several levels of product category in this one table, instead of having one table for each level, and using foreign keys referencing those values.</p> <p>This means you have normalization with regard to facts, but stop normalizing on the dimension tables.</p> <p>Furthermore, you often do not even completely denormalize the facts. A typical example would be this: in a completely normalized table, you would use only two columns 'number of units sold' and 'price per unit', but in an OLAP database, it may make sense to redundantly have another column for the 'sales value' which could easily be calculated by multiplying units sold and the price per unit.</p> |

Also note that all 10 characters of <code>name1</code> and all 20 characters of <code>name2</code> are written to the file, which may or may not be what you want.</p> <p>The situation gets even more complicated if your struct contains pointers, because what gets stored to the file is the pointer value, not the thing being pointed to:</p> <pre><code>#include <stdio.h> int main(void) { struct foo { int x; char *name1; char *name2; } items[] = {{1,"one","ONE"}, {2,"two","TWO"}}; FILE *output = fopen("binio.dat", "w"); fwrite( items, sizeof items, 1, output ); fclose( output ); return 0; } </code></pre> <p>This time I get</p> <pre> john@marvin:~/Development/Prototypes/C/binio$ cat binio.dat οΏ½οΏ½οΏ½οΏ½οΏ½οΏ½οΏ½οΏ½john@marvin:~/Development/Prototypes/C/binio$ john@marvin:~/Development/Prototypes/C/binio$ od -c binio.dat 0000000 001 \0 \0 \0 260 205 004 \b 264 205 004 \b 002 \0 \0 \0 0000020 270 205 004 \b 274 205 004 \b 0000030 </pre> <p>Note that none of the strings appear in the file at all; if you read this file in with a different program, all it will see are (most likely) invalid addresses. </p> <p>If you want your output to be human-readable <em>and</em> you want to be able to read those values in on a different architecture, you almost have to go with formatted output, meaning you have to write each member separately:</p> <pre><code>#include <stdio.h> int main(void) { struct foo { int x; char *name1; char *name2; } items[] = {{1,"one","ONE"}, {2,"two","TWO"}}; FILE *output = fopen("binio.dat", "w"); int i; for (i = 0; i < sizeof items / sizeof items[0]; i++) { fprintf(output, "%d %s %s\n", items[i].x, items[i].name1, items[i].name2); } fclose( output ); return 0; } </code></pre> <pre> john@marvin:~/Development/Prototypes/C/binio$ cat binio.dat 1 one ONE 2 two TWO </pre> <p>You can certainly wrap that operation in a function of your own, something like</p> <pre><code>int printFoo( FILE *output, const struct foo item ) { return fprintf( output, "%d %s %s\n", item.x, item.name1, item.name2); } </code></pre> <p>but in the end, that's about as simple as it gets.</p> <p>The <code>fwrite</code> solution works great if you're not concerned about readability and portability, but you still have to be careful if you have any pointer members within the struct. </p> |

I would think that calling this method inside the class would cause every instance I make to have it called- making them potentially move. </p> <p>Any help would be really appreciated.</p> |

28,872,472 | 0 | <p>What you need to do inside your stored procedure is split the comma delimited list of numbers into a list of single values in rows. Once you have this you can use <code>WHERE myCol IN(SELECT v FROM @r)</code>, or use an INNER JOIN instead of IN. One point you might have to watch for is that you have leading zeros - if you want to keep those you will need to use strings instead of integers.</p> <p>There are lots of articles around on the subject of splitting delimited values into rows, you could start <a href="http://stackoverflow.com/questions/2647/how-do-i-split-a-string-so-i-can-access-item-x">here</a>.</p> |
38,396,949 | 0 | <p>You can see there are comments in aapt_rules.txt. Beside each kept class there are corresponding layout files that referenced this class. Like that:</p> <pre><code># view res/layout/abc_list_menu_item_layout.xml #generated:17 # view res/layout/abc_popup_menu_item_layout.xml #generated:17 -keep class android.support.v7.internal.view.menu.ListMenuItemView { <init>(...); } </code></pre> <p>If you remove the layout file from build process this line will desappear and class will not be kept. The class will be shrinked if it's not actually used somewhere.</p> <p>So how can we remove layout file from appcompat library? I can see few options, none of them is perfect but they work. </p> <ol> <li><p>You can just remove file from sdk\extras\android\m2repository\com\android\support\appcompat-v7\version\appcompat-v7-version.aar. Enough for testing, bad for production because the same file may be used in some other projects. I tried and it works.</p></li> <li><p>Put fake file with the same name into your project. Name conflict will happen. Build process will prefer your fake file because project files have higher priority. This way file from appcompat will be ignored. I tried and it works.</p></li> <li><p>Probably you can make some fancy gradle script that removes unwanted files during the build process. I haven't tried that.</p></li> </ol> <p>(shrinkResources option doesn't help because aapt_rules.txt is generated BEFORE shrinkResources is actually involved.)</p> <p>I hope somebody will suggest a better way to do that</p> <p>After doing that all unwanted lines were gone from aapt_rules.txt. But it saved me about 100 KB from the final apk size. So not big deal for me. But in your case results may be different.</p> |
20,296,286 | 0 | <p>I don't claim to fully understand the <em>why</em> here, but as best I can tell, this is what's going on.</p> <p><code>summary.default</code> actually calls <code>oldClass</code> rather than <code>class</code>. <em>Why</em> I'm not sure, although I'm sure there's a good reason. </p> <p>Somewhat cryptically in <code>?class</code> we find the following passages:</p> <blockquote> <p>Many R objects have a class attribute, a character vector giving the names of the classes from which the object inherits. <strong>If the object does not have a class attribute, it has an implicit class, "matrix", "array" or the result of mode(x) (except that integer vectors have implicit class "integer").</strong> (Functions oldClass and oldClass<- get and set the attribute, which can also be done directly.)</p> </blockquote> <p>So what's going on here is that <code>class</code> returns the <em>implicit</em> class (numeric). Note that <code>attr(a$alpha,"class")</code> returns <code>NULL</code>. Since the attribute doesn't exists, <code>oldClass</code> faithfully returns <code>NULL</code>.</p> <p>As for the differences between mode, type and class, the first two are related, the third is sort of a separate idea. Mode and type are (I think) actually fairly well explained in the documentation. <code>mode</code> tells you the storage mode of an object, but it is relying on the result of <code>typeof</code>, so they are (mostly) the same. Or connected, at least. But the different values that <code>typeof</code> returns are simply collapsed down to a smaller subset.</p> |

4,134,999 | 0 | <p>Typing six file names, or using the declarative style with #pragma comment(lib, "foo.lib") is small potatoes compared to the work you'll have to do to turn this into a DLL or COM server.</p> <p>The distribution is heavily biased towards using this as a static link library. There are only spotty declarations available to turn this into a DLL with __declspec(dllexport). They exist only in the 3rd party dependencies. All using different #defines of course, you'll by typing a bunch of names in the preprocessor definitions for the projects. </p> <p>Furthermore, you'll have a hard time actually getting this DLL loaded at runtime since you are using it in a COM server. The search path for DLLs will be the client app's when COM creates your control instance, not likely to be anywhere near close to the place you deployed the DLL.</p> <p>Making it a COM server is a <em>lot</em> of work, you'll have to write all the interface glue yourself. Again, nothing already in the source code that helps with this at all.</p> |
