I have an image byte[], this byte[] is coming from LDAP [Oracle Open LDAP Authentication Provider] and I need to show this image into the page. How can I do this?Can I use javax.faces.context.ResponseWriter to write the byte[] or I should extract an instance of java.io.OutputStream from the javax.faces.context.FacesContext and write the byte[] into page. If any one of these methods is possible, then I can might be able to create a custom JSF tag, to display the image, and try to execute the image creation in encodeBegin(FacesContext context, UIComponent component) method of...

Number of instances or the content of the instances more important (machine learning)?

Say in the document classification domain, if I'm having a dataset of 1000 instances but the instances (documents) are rather of small content; and I'm having another dataset of say 200 instances but each individual instance with richer content. If IDF is out of my concern, will the number of instances really matter in training? Do classification algorithms sort of take that into account?Thanks.sam You could pose this as a general machine learning problem. The simplest problem that can help you understand how the size of training data matters is curve fitting. The uncert...

$+ in makefile

What does $+ in a GNU makefile mean?Also, please give me some good lookup manual for writing makefiles. From the make manual: $^    The names of all the prerequisites, with spaces between them. For prerequisites which are archive members, only the member named is used (see Archives). A target has only one prerequisite on each other file it depends on, no matter how many times each file is listed as a prerequisite. So if you list a prerequisite more than once for a target, the value of $^ contains just one copy of the name. This list does not contain ...

Using f-string with format depending on a condition

How can I use f-string with logic to format an int as a float? I would like if ppl is True to format num to 2 decimal places, and if ppl is False to rformat it as whatever it is.Something like string = f'i am {num:.2f if ppl else num}' but this does not work. The below code demonstrates the behaviour that I want to achieve with a simpler f-string if possible:ppl = Truenum = 3string = f'I am {num:.2f}' if ppl else f'I am {num}'print(string)#if ppl False#=> i am 3#if ppl True#=> i am 3.00 You can nest expressions to evaluate inside expressions in an f-string. This me...

Javascript Date Object gives different timezones for differently formatted date strings

Does anyone know why the Javascript Date object changes the timezone based on how your string is formatted and if there is a way to avoid it?For example, on the West coast (Firefox uses PST for some reason, Chrome uses PDT),new Date("08/30/2018") -> Date 2018-08-30T08:00:00.000Zwhilenew Date("2018-08-30") -> Date 2018-08-30T00:00:00.000ZIt took me a while to debug this issue, and I would rather not have to add extra code, if possible, for changing the timezone or reformatting the input string. I don't have an answer from the spec, but I can guess. @charlietfl is o...

Ideas for Implementing multiple views for the same data

I am using CodeIgniter, but the question applies to any MVC framework. I have a custom CMS which allows for the management of 5 different websites. Users log in and switch between these sites. They can add content to each of the areas of the sites. The CMS and data that can be entered is the same for each site. The public facing sites all look completely different and represent different brands even though they contain the same data as all the others. So how would you go about implementing these views? Are there any design patterns I should be looking at? The only way I can...

Workaround for drawing bug when Overlaying a <div> over an <iframe> in Safari?

I'm getting a very weird drawing bug in Safari, and i would like to see if there's any workaround I could take...I'm currently displaying a <div> (absolutely positioned, high z-index) on top of an IFrame that displays contents from other sites. Just for context, the <div> is a toolbar we show over other sites.This works well in all browsers, but in Safari, when the IFrame is showing some sites, and the user scrolls the page in the IFrame, the drawing of the toolbar gets all screwed up.Here is a very minimalistic POC that reproduces the problem:<html><he...

Frama-c fails to prove fact about pointer comparison

Consider the following C code:#include <assert.h>//@ requires p < q;void f(char *p, char *q){ assert(p <= q-1);}//@ requires a < b;void g(int a, int b){ assert(a <= b-1);}Using alt-ergo, frama-c successfully proves that the assertion in g() holds but fail to prove the same with f(). Why? Formally, pointers and integers are two very different things. In particular, C semantics states that pointer comparison is well defined only for pointers that points in the same allocated block (or one offset past the end of said allocated block) . This is reflec...

React Native: ignore files in a CodePush update

My use case is that I have an env file and its contents are replaced each time I build the app through Appcenter with environment variables. I fear that when I update the file locally (for example add another variable), the file would be overwritten in next CodePush release (so basically the build from Appcenter after the vars are replaced will have different contents of this file in comparison with what CodePush will see). Is this the correct assumption? If it is, is there a way to exclude certain files from a CodePush update? Thanks. I'm using react-native-config, and ...
