1. introduction to javaee-JavaEE foundation series 2019-04-20
what is Java EE?Is it really what you understand? Java EE, formerly known as J2EE, whose core consists of a series of abstract standard specifications, is a solution to the problems commonly faced in current software development. Pay attention to the word " abstract" in the above definition.Java EE is just a set of interfaces and specifications, providing a public API for developers. These abstract specifications can also be said to be standards.

code is here: from PIL import Image import os.path import glob def convertjpg(jpgfile,outdir,width=128,height=128):  try:  new_img=img.resize((width,height),Image.BILINEAR),os.path.basename(jpgfile)))  except Exception as e:  print(e) for jpgfile in glob.glob("/home/aa/qxq/project/fruits/database/fruitsVegtables/tomato/*.jpg"):  convertjpg(jpgfile,"/home/aa/qxq/project/fruits/database/fruitsVegtables/tomato")  

Book isbn Batch Generation of One-dimensional Barcodes 2019-04-20
Book isbn bar code is a one-dimensional bar code printed on the lower right side of the back of the book, which can be read with a scanning gun with high speed and accuracy.Most of the time, we need to generate the one-dimensional barcode in batch, input the isbn number to be converted into a column in xls, and then use this tool software to automatically generate the corresponding one-dimensional code.

Deep Residual Learning 2019-04-20
Looking at the milestone of CNN network, the latest deep residual network ResNet Microsoft's deep residual network ResNet originated from 2016 CVPR best paper-deep residual learning for image recognition, paper: pdf This 152-layer ResNet architecture is deep. In addition to setting a record on the number of layers, the error rate of ResNet is surprisingly low, reaching 3.6%, and human beings are at a level of about 5% ~ 10%.
