Clash Royale CLAN TAG #URR8PPP Get list of files using Boto from Private S3: 403 Forbidden I would like to get a list of files that exist in a private S3. Generally, I do the following: from boto.s3.connection import S3Connection from boto.s3.key import Key aws_access_key_id = "XXX" aws_secret_access_key = "YYY" conn = S3Connection(aws_access_key_id, aws_secret_access_key) bucket = conn.get_bucket('bucket-name') these_files = ["s3://bucket-name/" + f.name for f in list(bucket.list("", ""))] However, if I were to read the file in pandas I get 403 Forbidden Error . I found the solution here to get a file such as: 403 Forbidden Error bucket = conn.get_bucket('bucket', validate=False) k = bucket.get_key('file.csv') df = pd.read_csv(k) The problem with this solution is that it requires the user to know the file name in advance. I could avoid this by creating a custom function: def readS3_files(f): filename = f.s...

Clash Royale CLAN TAG #URR8PPP How to reduce repeatedly and dynamically generated html I am in the middle of revising a website and it has a significant problem with rendering time. I looked into what is causing the problem and it turns out that table-generating mechanism that I am using takes way too much time. As needed data gets queried from DB, the table is dynamically generated in repeated format. (as shown below in the code) Table size increases as scrolling down to bottom. Instead of generating additional table every time additional queries are done, is there any way to get by and reduce the rendering time? Here is a snippet of HTML structure generated. (there are more than 10000 rows in the same format but with different contents) Thank you very much for your help in advance! <tr class="doc_field_vendor_item"> <td width="150px" align="center" class="item"> <div id="invno1127">16011304</div> </...

Clash Royale CLAN TAG #URR8PPP How to pass a vector to the dots (…) argument of a function Several R functions have and arguement ... that allows you to pass an arbitrary number of arguments. A example of this is the paste function, to which you can provide an arbitrary number of arguements. But sometimes, you don't know ahead of time how many arguements you want to pass. ... paste For example, say I want to produce a plot in ggplot, where I want to color points by the combination of two columns: df <- data.frame(x=rnorm(100), y=rnorm(100), cat1=sample(c(TRUE, FALSE), 100), cat2=sample(c(TRUE, FALSE), 100), cat3=sample(c(TRUE, FALSE), 100)) ggplot(df) + aes(x=x, y=y, col=paste(cat1,cat2) + geom_point() But now consider that I want to the list of columns to be colour by to be determined at run-time. I would like to write a function that did something like: library(rlang) color_plot <- function(df, color_by) color_by = lapply(color_by, sym) ggplot(df) + aes(x=x, ...

Clash Royale CLAN TAG #URR8PPP How to implement dirty state in VueJs I am new to VueJs and I am working on a form that I want to enable the Save button only when a change occurs at the model.

For example, to plot a single vector in series, I could simply do: qplot(seq_along(vec1),vec1)) But I want to plot both in series, so we can pairwise compare the entries visually. The graph would look something like: Thanks! I would suggest looking at the ggplot documentation, essentially you just need a plot canvas with multiple stored vectors or if you convert the vectors in to a df you can just pass the df in. – Mike Tung Aug 8 at 17:36 1 Answer 1 We need to make a data frame from vec1 and vec2 . Since ggplot2 prefers data in long format, we convert df to df_long using gather from the tidyr package (after creating id column using mutate function from the dplyr package). After that it's fairly easy to do the plotting. vec1 ...

Clash Royale CLAN TAG #URR8PPP Kafka : Check if 2 topics have been caught up I have 2 topics in kafka which I am double writing to. Their offsets are at different commit points to begin with. My consumer starts consuming from the second topic late, but eventually will catch up with the first topic. How can I optimally find out if both of them are caught up ? I am planning to look at a fixed window of previous messages consumed from both the topics and check if the messages consumed are similar in nature. Any ideas of how I can find if they are similar ? Any other ideas of how I can be sure that they have been caught up ? Also, my topic has multiple partitions. The check should include if all partitions have been caught up.

Clash Royale CLAN TAG #URR8PPP Macro for template definitions I have a problem with alias template, because I have a code which must be compatible with VS 2012, which does not support alias template. Let's say I have an alias template like: template<typename A, typename B> using foo = bar<A,B>; Then it would be very convenient to be able to do something like: #ifdef NO_ALIAS_TEMPLATE_AVAILABLE #define foo<x,y> bar<x,y> #else template<typename A, typename B> using foo = bar<A,B>; #endif However the best I can do is #define foo(x,y) bar<x,y> And I don't want to replace all template specializations in all my code by round brackets, for code readability.

The code that I'm currently using has to open the excel file. Is there a way to do this in the background ? Is there a way to read values row by row from the first column?

But if you're looking for other options: The xlsx file is actually a zip file. You could open it as a zip file and extract the contents. This can be done without starting Excel. So it should be faster. https://m...
