adb – Android Version differs from expected API level

I have found a pretty old device Huawei Ascend Y210. This mobile officially has Android 2.3.3 (API level 10). I found an online custom lollipop ROM for the specific mobile. The device has CWM as custom recovery. The zip file (the rom file) was installed successfully. The environment feels like android Lollipop should look like. Going to the mobile’s settings > About phone > Android version, the version is 5.0.1 as expected. Using the command adb shell getprop the result is 5.0.1 indeed. However, I tried running adb shell getprop the result is 10 which is the API level of the stock android of the phone (Android 2.3.3). Apps made from API level 23 will fail to install as the API level is getting recognized as 10. Changing the apps’ Minimum API level to 10 using APK Editor Studio, allows the app to get install but it crashes once I try to open it.

Is that a bug? I mean can I somewhere change the API level of the device? Or is the ROM a scam and the android is never really getting updated to 5.0.1 and the ROM just changes the graphic interface? How is it even possible to trick the adb that the android version is 5.0.1 but keep the API level to 10?

P.S.: If someone has any ROM for Huawei Ascend Y210 with android 5.0.1 or higher handy, I would appreciate a download link.

Thanks in advance!

csom – Lists.GetByTitle (SPlist) – title differs by language

When I request collection of the list on a sharepoint site by

Dim collList As ListCollection = Web.Lists

the "Documenten" list appears in the list.

But if I want to approach this list with


I get the error that the list does not exist.

If I use


it works well…

So it's a language problem.

Question: how can I use "GetByTitle" with a title as it appears in the collection list?

The data definition language (DDL) differs from a type declaration language such as Java?

Which of the following is a way in which a data definition language (DDL) differs from a type declaration language such as Java (the language, not what can be done with the language)?
a) The execution of an action in the DDL results in the creation of an object in the database.
b) DDLs allow you to specify consistency constraints.
c) DDLs support authorization, granting different access rights to different users.
All the foregoing. (Tip: a description of this answer would identify the characteristic of the corresponding type definition language / its absence for each of the three DDL characteristics.)
e) None of these answers. (Tip: a description of this answer would identify at least two ways that a DDL differs from a type declaration language.

separate cookie – Bitcoin Segwit battery value differs

I signed a bitcoin testnet transaction using the nbitcoin library and I got an output:


then i signed the same transaction with bitcoin-core and it returned an output:


When comparing the outputs, the value of the txwitness stack differs.

bitcoin-core cookies

"txinwitness": [

NBitcoin cookie data

 "txinwitness": [

But still, I can send the transaction signed by nBitcoin.

My questions are therefore:

1] what are the values ​​in the witness stack?

2] why the same transaction has a different txwitness value?

Server wait time differs from factor 10 on the same server

I have two sites running on the same server. They use the same configuration (PHP version, WordPress settings, HTTPS, rules .htaccess, etc.) While a site indicates in Pingdom a delay of about 30 ms for images, the Another displays a 10-fold timeout for a JPG file of similar size. Both sites are pretty fast, but the first is considerably faster. I have absolutely no idea what could cause this huge difference. Ideas?

reports – Google Analytics: the output page report differs from conversions

I have a problem to determine the exit percentage of my payment pages.

Looking at the event information from the site database for a day, I am given the following information:

  1. Login to Cart – 306
  2. Payment completed – 249
  3. 81% completed (completed / entered checkout)
  4. 19% went out (rest)

When I view my reports in Google Analytics, the following information is provided to me:

  1. Entry Entry – 304
  2. Payment completed – 247
  3. Outings – 26
  4. % Output – 0.09% (Inputs / Inputs In)

So what is the reason why my exit% differs from the calculation between the difference between the payment entered and the payment completed?

Thanks in advance!

seo – Content generated by JavaScript appears on search engines, where the content differs on a single page

I have a PWA hosted on Firebase. On the main URL, like, there is a lot of content generated by JavaScript.

At the same time, whenever someone accesses, where the key and the value predefined, the JavaScript code of the page reads the key and the value and consequently deletes the content usually posted on and displays different content.

The content differs with each value of key.

With this, the website effectively acts as a multi-page website, although it essentially has only one webpage.

The problem is that I do not understand the content posted on these pages. subpages visible on Google Search (or any other search engine). Is there a workaround on this?

The problem here is that I can not generate a different web page (an HTML file) for each of these elements. subpages because the website uses only Front End technologies, available with Firebase.

linux – Unable to exploit buffer overflow based on a stack with ASLR disabled, because RSP differs significantly from one run to the other.

I have created a small toy program, compiled with ALSR disabled, that I wish to exploit with the help of a stack buffer overflow:

// gcc stackexec0x1.c -Wl, -z, execstack -no-pie -fno-stack-protector -o stackexec0x1


#define SBUFSZ 0x100
#define LBUFSZ 0x800

main int (int argc, char * argv[]) {
buf tank[SBUFSZ];
printf ("#");
objects (buf, LBUFSZ, stdin); // exploit that!
printf ("% s", buf);
returns 0;

I can easily overwrite the return address, stored on the stack, by a custom address. However, between consecutive executions of the program, the RSP register differs:


By calculating the differences between the RSP register values ​​above, we can see that they are large. It would not be possible to put a NOP sled that covers most of it?

How can I easily choose a return address in the NOP-sledge + payload packet from the stack, so that it is executed (with high probability) when the function returns?
