blob

I want to deploy an app in Heroku to try their new Play! Framework support. For what I've read in the site (I gotta confess I did not try it yet) they don't provide any file system. This means that (probably) Blob fields used in Play to store files won't work properly. Could somebody: Confirm if you can use the Play Blob in Heroku? Provide the "best" alternative to store files in Heroku? Is better to store them in the database (they use PostgreSQL) or somewhere else? I put an example of how to do this with Amazon S3 on github: https://github.com/jamesward/plays3upload Basically you just need

I write binary data from pictures into my SQLite database into a BLOB field called "icondata". CREATE TABLE pictures(id INTEGER PRIMARY KEY AUTOINCREMENT, icondata BLOB) The code snippet to write the binary data is: SQLcommand.CommandText = "INSERT INTO pictures (id, icondata) VALUES (" & MyInteger & "," & "@img)" SQLcommand.Prepare() SQLcommand.Parameters.Add("@img", DbType.Binary, PicData.Length) SQLcommand.Parameters("@img").Value = PicData This works fine and I can find the BLOB values in the database using a tool like SQlite Spy . But how can I search for a specific "icondata" BLOB? If I

1.结构信息 net是ncnn的核心部分，起着组织整个框架结构的作用，捋顺net的结构，基本上对ncnn的代码框架也就有一个大概的了解了。首先看一下net的类结构信息。 class Net { public: int usewinograd_convolution; //是否使用winograd进行卷积 int use_sgemm_convolution; //是否使用矩形乘法的形式进行卷积 int use_int8_inference; //是否使用int8进行推断 int use_vulkan_compute; //是否使用gpu int load_param(FILE *fp); //从参数文件中读取网络结构 int load_model(FILE *fp); //从模型文件中读取模型参数 Extractor create_extractor(); //net中的另一个类Extractor protected: std::vector<Blob> blobs;//网络的所有blob，但是不包含blob的具体数据（nchw维数据） std::vector<Layer*> layers;//网络的所有层指针 int forward_layer(int layer_index, std::vector<Mat> &blob_mats, Options &opt); int find

ncnn也使用了类似caffe中的blob作为最基本的数据结构来存储计算过程中的各种数据。 1.blob结构体 class Blob { public: std::string name; int producer; // 指明该blob是哪个层的输出，同时说明，一个blob只能由一个层输出 std::vector<int> consumers; // 指明该blob哪个层的输入，一个可以同时输入多个层 }   由blob类结构可以看出blob类本身不存放具体的计算数据，只负责关联blob和相应层（该blob是哪个层的输出，哪个层的输入） 真正的blob数据存放在blob_mats里，索引与blob一致，而blob_mats存放在net.h中的Extractor结构体中。 来源： https://www.cnblogs.com/ganchunsheng/p/11673946.html

I am trying to load a large video into a tag using XMLHttpRequest. I've successfully gotten this to work with small video files using the following code: window.URL = window.URL || window.webkitURL; var xhr = new XMLHttpRequest(); xhr.open('GET', 'quicktest.mp4', true); xhr.responseType = 'blob'; xhr.onload = function(e) { var video = document.createElement('video'); video.src = window.URL.createObjectURL(this.response); video.autoplay = true; document.body.appendChild(video); }; xhr.send(); No problem if the video is small. However, my file is quite large and creates an out-of-memory error,

How to specify blob type in MS Access? I have office 2007 installed. I am using jdbc, but this should not matter for the SQL query I am passing. Tried to pass a length to it, or FILE type, did not help. CREATE TABLE mytable ( [integer] INTEGER not null, [string] VARCHAR (255) , [datetime] DATETIME , [boolean] BIT , [char] CHAR , [short] SHORT , [double] DOUBLE , [float] FLOAT , [long] LONG , [blob] BLOB , // does not work Primary Key ([integer]) ) HansUp Use LONGBINARY as the data type for the blob field in your DDL statement. See Field type reference - names and values for DDL, DAO, and ADOX

I am creating webapplication using JSF2.0 where in mysql, I am storing images using datatype as MEDIUMBLOB . To insert values, I am using PreparedStatement as shown below. PreparedStatement psmnt = con.prepareStatement("INSERT INTO sketchesSG002003 (userid, imageTitle, imageData, drawingComments) VALUES (?,?,?,?)"); psmnt.setLong(1, personalInfoId); psmnt.setString(2, sketchesSG002003Title); try { String fileName = FilenameUtils.getName(sketchesSG002003ImageUpload.getName()); File image = new File(fileName); InputStream fis = sketchesSG002003ImageUpload.getInputStream(); psmnt.setBinaryStream
