2,692,829 | 0 | HTTP Response 412 - can you include content? <p>I am building a RESTful data store and leveraging Conditional GET and PUT. During a conditional PUT the client can include the Etag from a previous GET on the resource and if the current representation doesn't match the server will return the HTTP status code of 412 (Precondition Failed). Note this is an Atom based server/protocol.</p> <p>My question is, when I return the 412 status can I also include the new representation of the resource or must the user issue a new GET? The HTTP spec doesn't seem to say yes or no and neither does the Atom spec (although their example shows an empty entity body on the response). It seems pretty wasteful not to return the new representation and make the client specifically GET it. Thoughts?</p> |

12,924,058 | 0 | <p>One complexity of MIDI files is <a href="http://dogsbodynet.com/fileformats/midi.html#RUNSTATUS" rel="nofollow">Running Status</a>. If there's sequence of messages of the same type and channel (eg all controllers or all notes) then MIDI can save a number of bytes by omitting the status byte. If this didn't use running status then the bytes you would see are:</p> <pre><code>00 B0 79 00 - controller 121: controller reset 00 B0 5B 00 - controller 91: reverb 00 B0 40 00 - controller 64: sustain 00 B0 07 64 - controller 7: volume 00 B0 0A 10 - controller 10: pan 00 90 3E 47 - note message </code></pre> <p>Because all the controller messages are contiguous and are for the same channel, the status byte can be omitted. As soon as there's a change of message type, the status byte has to be added again.</p> <p>If you're trying to make sense of MIDI files then I would recommend using a separate tool such as <a href="https://github.com/vishnubob/python-midi" rel="nofollow">Python-MIDI</a> or <a href="http://www.gnmidi.com/" rel="nofollow">GNMidi</a> as a sanity checker whenever there's a MIDI event you can't make sense of. These can show it as text so you can mimic what it's doing.</p> <p>EDIT: Another gotcha to be aware of is that any MIDI messages that take a length or duration parameter (eg the time in PPQN between events in a MIDI file, or the length of sysex messages or meta events) uses a variable length, so don't assume all the length fields are always a fixed length.</p> <p>Disclaimer: I wrote the MIDI export code in Sibelius 6...</p> |

So you really want to just figure out "what Javascript that I wrote was being run right before that broke?", and start there.</p> |

10,705,624 | 0 | TeamCity building MSP files <p>For background: I've got quite a nice TeamCity setup; containing a ci build and a release build which uses WiX to build my installers and patch all the version numbers. When I do a new release build, I'd like to automatically create MSP patches against a previous set of installers. I'm thinking either tagged RTM in TeamCity, or as a list of version numbers.</p> <p>The approach I'm leaning towards is creating a separate config and getting the msi artifacts of all the previous builds that fit the criteria (tag or version number). Tag would seem a lot neater, but I can't see anything in the documentation about how you use it?</p> <p>I've got a script to build the MSP patch, but it relies on a PCP file which needs to be edited in ORCA to describe the patch. </p> <ol> <li>In terms of editing the PCP, is there anything else I can use other than the ORCA to edit?

36,001,963 | 0 | <p>Partitionkey and Rowkey are just two properties of entitis in Azure table. Rowkey is the "primary key" within one partition. Within one PartitionKey, you can only have unique RowKeys. If you use multiple partitions, the same RowKey can be reused in every partition. PartitionKey + RowKey form the unique identifier(Primary key) for an entity. </p> <p>In your table, the partitionkey and rowkey are just assigned with a random string. I'm not sure whether you designed this table or somebody else, but these two properties can be assigned with other values through <a href="https://azure.microsoft.com/en-us/documentation/articles/storage-dotnet-how-to-use-tables/" rel="nofollow">Azure Storage .NET client libary</a> and <a href="https://msdn.microsoft.com/en-us/library/azure/dd179433.aspx" rel="nofollow">Rest API</a>. As the example below, you can design the rowkey and partitionkey, and assign whatever valid value you want, here lastname for Partitionkey and firstname for rowkey:</p> <pre><code>public class CustomerEntity : TableEntity { public CustomerEntity(string lastName, string firstName) { this.PartitionKey = lastName; this.RowKey = firstName; } public CustomerEntity() { } public string Email { get; set; } public string PhoneNumber { get; set; } </code></pre> <p>}</p> <p>It’s better to think about both properties and your partitioning strategy. Don’t just assign them a guid or a random string as it does matter for performance.

6,713,460 | 0 | <p>To avoid string processing, lambdas are a good solution as in the answer by Johannes Schaub. If your compiler doesn't support lambdas yet then you could do it like this with no C++0x features and no macroes:</p> <pre><code>doTrace(LEVEL_INFO, some_props) << "Value of i is " << i; </code></pre> <p>doTrace would return a temporary object with a virtual operator<<. If no tracing is to be performed, then return an object whose operator<< does nothing. Otherwise return an object whose operator<< does what you want. The destructor of the temporary object can signal that the string being outputted is done. Now destructors shouldn't throw, so if the final processing of the trace event can throw an exception, then you may need to include an end-of-event overload of operator<<</p> <p>This solution causes several virtual function calls even when no tracing is done, so it is less efficient than "if(tracing) ...". That should only really matter in performance critical loops where you probably want to avoid doing tracing anyway. In any case you could revert to checking tracing with an if in those cases or when the logic for doing the tracing is more complicated than comfortably fits in a sequence of <<'s.</p> |
29,016,131 | 0 | SVG: Why <p> element is not displaying in <foreignobject> <p>I'm attempting to put a <code><p></code> element inside a <code><foreignobject></code> inside an <code><svg></code> node in chrome but I am not seeing the text. I have inspected the element and the DOM model shows the structure I expect. I created this <a href="http://jsfiddle.net/ujzL8yyr/" rel="nofollow">jsfiddle</a> by copying from the DOM model and lo and behold it works exactly as I desire in the fiddle.</p> <p>After scratching my head for a bit I started looking at the properties in the two tabs (both in Chrome) and the only 2 things at this point that jump out me are that when I hover over the <code><foreignobject></code> or <code><p></code> element in the fiddle, it shows a grey box the area where it's displayed. When I do this in the real application, it does the same for the <code><foreignobject></code> but I see nothing for the <code><p></code> element. The second difference is that in the fiddle, the <code><p></code> element shows a height and a width of 54px and 100px (respectively) but in the actual application they both are reported to be 'auto'.</p> <p>As an experiment, I attempted to set the height and width explicitly in the CSS for 'p' but chrome just shows this as an 'invalid property'.</p> <p>Assuming this is the problem, I'm a little lost as to how to control a property that I'm not allowed to specify. Can someone help with some advice on how to debug this further? There's clearly something about what I am doing that is causing this but I'm not sure where to look next.</p> <p>EDIT:</p> <p>I don't know why I didn't notice this before but I see a difference that may help explain this. The fiddle shows the properties for the <code><p></code> element as:</p> <ul> <li>p.description</li> <li>HTMLParagraphElement</li> <li>HTMLElement</li> <li>Node</li> <li>EventTarget</li> <li>Object</li> </ul> <p>The application shows these properties:</p> <ul> <li>p</li> <li>SVGElement</li> <li>Element</li> <li>Node</li> <li>EventTarget</li> <li>Object</li> </ul> <p>I assume this has something to do with how d3 is adding the <code><p></code> element.

34,375,310 | 0 | how to assign query to GridItem in SearchView? <p>I am trying to create a SearchView that searches for GridItems that each launch a specific second activity. However I cannot figure out the code that will help me with this. I have already set an onQueryTextChangeListener for the SearchView which should allow me to show results manually and whilst typing. Here's what I want to happen:</p> <p>When I type a specific query, let's say "car", I want to show the GridItem (which is just a clickable ImageView) of a car to the user. When I type "Camera", I want to show the user my GridItem with the image of a Camera on it.</p> <p>I also want to display results to the user whilst typing, so when I have only typed "c" yet, I want to show the user both the "car" and "Camera" GridItems. I want to stay in the same activity, so I need some sort of way to delete all GridItems except for the ones with a camera or a car picture on it depending on what the user typed, I don't want to launch a search activity.</p> <p>Now what makes this just a little harder is that I configured my BaseAdapter in a separate class, which means that I have to indirectly mention the GridItems in some way. Here's what I've done so far:</p> <pre><code> @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.menu, menu); final MenuItem searchItem = menu.findItem(R.id.action_search); SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem); searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() { @Override public boolean onQueryTextSubmit(String query) { if (query.equals(R.string.Coconut)){ //here I need some code that will tell the system that I want to show the GridItem with a picture of a coconut on it } return false; } @Override public boolean onQueryTextChange(String newText) { return false; } </code></pre> <p>This is the separate class that initialises the Images in the GridView:</p> <pre><code>class SingleItem{ int image; double nutritional_value; SingleItem(int image, double nutritional_value){ this.image = image; this.nutritional_value = nutritional_value; } } public class objectAdapter extends BaseAdapter { ArrayList<SingleItem> list; Context context; Bundle myBundle; objectAdapter(Context context) { this.context = context; myBundle = new Bundle(); double[][] nutritional_value = { {89, 22.8, 0.3, 1}, {61, 1.5, 0.5, 1.1}, {375, 6.8, 0.6, 1.2}, {767, 0, 9.3, 0}, {580, 9.1, 42, 36.5} }; myBundle.putSerializable("array_array", nutritional_value); int[] image_id = { R.drawable.Bananas, R.drawable.Kiwis, R.drawable.oatmeals, R.drawable.coconuts, R.drawable.dark_chocolate }; for (int i = 0; i < image_id.length; i++) { SingleItem tempSingleItem = new SingleItem(image_id[i], nutritional_value[i][i]); list.add(tempSingleItem); } } @Override public View getView(int position, View convertView, ViewGroup parent) { View row = convertView; ViewHolder holder = null; if (row == null) { LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); row = inflater.inflate(R.layout.single_item, parent, false); holder= new ViewHolder(row); row.setTag(holder); } else { holder = (ViewHolder) row.getTag(); } SingleItem temp = list.get(position); holder.myItem.setImageResource(temp.image); holder.myItem.setTag(temp); return row; } @Override public long getItemId(int position) { return position; } class ViewHolder { ImageView myItem; ViewHolder(View v){ myItem = (ImageView) v.findViewById(R.id.imageView2); } } @Override public Object getItem(int position) { return list.get(position); } @Override public int getCount() { return list.size(); } } </code></pre> <p>Thanks in advance!</p> <p>Vidal</p> |

7,784,436 | 0 | <p>First, your code does not have any effect. Hash table "breaks" the order. The order of elements in hash table depends on the particular hash implementation. </p> <p>There are 2 types of Maps in JDK: HashMap and SortedMap (typically we use its implementation TreeMap). BTW do not use Hashtable: this is old, synchronized and almost obsolete implementation). </p> <p>When you are using HashMap (and Hashtable) the order of keys is unpredictable: it depends on implementation of <code>hashCode()</code> method of class you are using as keys of your map. If you are using TreeMap you can use Comparator to change this logic. </p> <p>If you wish your keys to be extracted in the same order you put them use <code>LinkedHashMap</code>.</p> |
