How I fixed blurry/fuzzy image on Samsung Galaxy s6?
The solution was amazingly simple: shake the phone very aggressively!. Looks like the camera actuator mechanism sometimes gets stuck in a certain position. This will fix it.
You want to do amateur or power-level computing? Then there is no other choice than Windows! Period. As a Windows user you don't have to spend tons of a money for a Mac PC (sorry Mac guys but Mac is nothing else than an expensive PC now) and you don't have to waste time on forums to learn how install stuff. All that Linux/Mac can offer you can get on Windows and get is better. I spent many years working with Linux but it was always only my second choice. Sorry Linux friends, but I said it.

Can you tell if the machine on which you are running is a virtual machine installed secretly by some malware/hacker?
Somebody asked me: can you tell if the machine on which you are running is a virtual machine installed secretly by some malware/hacker?
I thought about that question and the answer is SURE. Without any doubt.
A virtual machine will consume some resources by itself (quite a lot). If you observe these missing resources you can figure out that something is wrong.
Method 1 - Graphics
You don't even need to start a program to accurately measure the missing resources.
You can tell if the machine in which you are running is a virtual machine or not, simply by running a game.
Most virtual machines have problems with accelerated graphics. Simply put, you cannot play resource-intensive 3D games in a virtual machine.
Method 2 - RAM
Now to tell exactly if you are running in a virtual machine, you don't need advanced hacker tools. Simply press Ctrl+Shift+Esc to start TaskManager. Under "Physical Memory (MB)" and watch the 'Total' field. In my case is shows 32GB which is indeed the amount I have physically installed. This number can be also seen in the Control Panel\All Control Panel Items\System (Win+Break key).
Method 2 - CPU
Another method is to run a tool like (Hardware ID Extractor) that gives you the theoretic speed of the CPU and the real (measured) speed of the CPU. If real speed of the CPU is smaller than the theoretic speed, then something is fishy.
Also the CPU ID might give info about this. I will investigate it.
Remember: also collaborate the data shown by software with writes on your actual CPU/RAM.

KSDev released this year CrossVCL - a framework that allows you to build multi-platform applications.
What is the difference between Firemonkey and CrossVCL?
If you want to make your current app multi platform, you need to port it to Firemonkey. With CrossVCL you don't need anything!!!
Embarcadero should fear them!
And learn a lesson form them!
They really upgraded Delphi/C++ programming to a brand new level!

Cool features and functions in Delphi
List of IDE features that are cool (when they work)
- Search backwards - Ctrl+F to do a search in your code. F3 to go to the next position Shift+F3 to go to previous position.
- Move/Relocate/Rename project's files directly from Project Manager
- Navigate to recently modified code - Ctrl+Shift+F7 and Ctrl+Shift+F8
- Search for usage - Right click a variable and invoke 'search for usage'. A panel will list all places in current project where that variable is used. In my cases this will make the IDE to freeze.
- UML diagrams (Live Diagrams) - simply doesn't work
- IDE insight (F6) - It could be useful but seems to list a lot of random items.
- CodeSite - a logging system - I couldn't really find it useful
- AQTime - Performance profiler + memory allocation debugger - I couldn't really find it useful
List of functions/units/classes that are cool (when they work)
- SysUtils.GetHomePath - Returns c:\users\username\appdata\roaming.
- IOUtils - Lots of new cool functions. Totally broken.
- SplitString - Example of usage at the end of this document. Unfortunately, the function is VERY slow!
- FindCmdLineSwitch - Example: System.SysUtils.FindCmdLineSwitch('-f', sFileName)
- TThread.ProcessorCount; { Specifies the number of CPU cores in the system }
- TBinaryReader / TBinaryWriter - Nice but only half ass - Interesting but I recommend this library which is much faster: https://stackoverflow.com/questions/5639531
- System.Diagnostics.TStopWatch - Can be used to precisely time your code.
- $WeakLinkRTTI - Put these two directives in your DPR file (at the very top) to reduce exe size with 4%:
{$WEAKLINKRTTI ON}{$RTTI EXPLICIT METHODS([]) PROPERTIES([]) FIELDS([])} - TStringBuilder - It was supposed to help you build strings. But it is horrible! Simply don't use it. It is painful slow.
- PtInCircle & PtInRect - Tells you if a point is located in a circle. Could be handy one day.
- TTimeSpan (System unit) is a data structure used for holding information about a period of time. The smallest unit of time is a tick which is 100 nanoseconds. The largest unit of time is a day.
- SLineBreak - global constant that changes its value depending on target platform (Win/Linux/Mac)
- Win32MajorVersion & Win32MinorVersion - To get current Windows version
List of VCL controls that are cool (when they work)
- TJumpList - To list a custom file in a JumpList your program must be registered (in Windows registry) to be able to open that type of file. Another problem is that when the user clicks a 'recent file' in the JumpList, the message is not sent to your app directly. You need to intercept that message.

Fix Firefox v57 (Firefox Quantum) high memory utilization (for computers with 4GB RAM or less)
When Firefox Quantum was launched everybody praised it as the next best thing (browser).
But if you look closelly you will only see modest speed improvements into the browser. HOWEVER, you will see massive slowdowns in Windows. At least I did in mine. Why because instead of taking 600-900MB for regular browsing the new Firefox takes not 2GB!
This is because a thing called "multi-process Firefox" was activated by default. The multi-process was suposed to make Firefox more stable. However, it also makes the browser much much larger.
So, how do you make Firefox behave? You disable multi-process:
1. Type "about:config" in Firefox Address bar (where you enter the address of a website).
2. Do a search for "browser.tabs.remote.autostart"
3. Disable it.

False antivirus reports on installers created with WinRAR
I recently observed that Setup files created with WinRar have a high false positive detection rate from antiviruses.
Here are the conclusions of some test I made, in order to reduce the false positive rate:
RAR version SFX module Detection ratio
WinRar 3.11 32bit 1/66
WinRar 4.2 32bit? 3/66
WinRar 5.50 32bit 6/67
WinRar 5.50 64bit 1/67
Notes:
The detection ratio is not affected by the 32/64 bit version of WinRAR program at all.
However, it is strongly affected by the SFX module used.
The test file created with WinRar was named Setup.exe and it contained a single URL file in it.
In one test, the Setup file was packed with UPX. This reduced the detection ratio from:
8 false positives to only 4
6 false positives to 6 (no reduction), in other case
A program built in Delphi raises more false positives if the 'Compiler optimizations' is on.

How to fix invalid Google Drive quota!
I recently have seen that 25% of my GDrive quota was occupied by something. But my GDrive has in it only 0.7GB. So, who gets the rest of the space.
It turns out that there are files in my Google Drive that are not assigned to a folder. Therefore they are "hidden" from view.
To see these files just click this link:
https://drive.google.com/drive/search?q=is:unorganized%20owner:me
Review what you want to keep/delete (probably you will delete them all) and get rid of them. Don't forget to empty your trash also.
No my quota shows only 6% occupied.

Yet another EurekaLog bug. How many until now?
I stepped last week in a multiple-bug situation with EurekaLog for Delphi. I again wasted MORE than a day with this buggy "exception tracer tool".
My DRP file is like this:
This worked fine until I compiled the program to 64 bits.
On 64 bit, EurekaLog refused to work. After lots of emails exchanged with their (slow) customer support I got NOTHING.
In the end I have found the problem: a bug (oh yes, another one) in EurekaLog. Eureka v7.4 could not properly parse the DRP file when it contains conditional directives like {$ifdef}.
So, because EurekaLog parse my dpr file was like this
Solution? None. The support guy from EurekaLog (Alex) invided me to pay for a new license on order to get a small update (same version, so update, no upgrade) to v7.5 which allegedly works. I won't do that. I should receive the UPDATE to the non-bugged version for free AT LEAST for the reason that I have invested time to help them locate the bug.

Delphi programs have too many false positive detections
Most of my Delphi programs are flagged as virus by some antivirus programs. Some of these antivirus programs are really cheap/under-the-table products (such as Baidu and Comodo) other are big (TOP) name like Kaspersky.
In theory you should report a false positive to the antivirus producers so they can fix their bug but if the list is too long and you are lazy here is what you can do to decrease the number of false positive reports:
In theory you should report a false positive to the antivirus producers so they can fix their bug but if the list is too long and you are lazy here is what you can do to decrease the number of false positive reports:
- Don't turn on "compiler optimizations" when you release your app. It seems that more false alarms are triggered when this is turned on in the project.
- If you MUST turn one the "compiler optimizations" you can pack your exe with UPX. This should shut up most antiviruses as they don't know to look inside the UPX
- If you use WinRar, downgrade to v3.11 as this version does not give false positives (only one out of 64).

How to configure EurekaLog to send bugs via email
Email sender settings in EurekaLog v7
1 - Many antivirus products will flag your EXE as virus
4 - could be enabled via SetUserEMail function)
| SMTP Server [1] | Simple MAPI | MAPI | Shell (MailTo) | SMTP client [3] | |
| Can attach the ELP file | Yes | Yes [2] | Yes [2] | No | Yes |
| See sender's email | No [4] | Yes | Yes | Yes | No |
| Email client software* | Not required | Required | Required | Required | Not required |
| Chance of success | Highest chance among all methods | High if email client installed | WinMail & Outlook only!! | High if email client installed | I get a 'revocation function' error but for others is working |
| Can tell if email was successfully sent? | No | Yes | Yes | Yes | Yes |
1 - Many antivirus products will flag your EXE as virus
2
- if "Append bug report text in the message text" is

- Typically, you should use either SMTP server or SMTP client, but
not both methods simultaneously.
Bugged in EurekaLog v7.4.8.0 RC 1 - Error code = -2146885613 - The revocation function was unable to check revocation because the revocation server was offline. Maybe because: “Currently EurekaLog supports AUTH LOGIN and AUTH PLAIN authentication methods”?

Another bug in EurekaLog 7
I wanted to send an email ("Send via
SMTP client") from EurekaLog v7.4.8.0 RC 1 but I was getting this error:
FAILED: Error code = -2146885613
The revocation function was unable to check revocation because the revocation server was offline

Testing send with TELMailSMTPClientSender
Options:

My email is hosted by BlueHost but knowing how buggy EurekaLog is and considering the fact that all my accounts work flawlessly in Thunderbird I think the bug is not related to the BlueHost server.
I had to give up using "SMTP client" and user "SMTP server" instead.

Total Commander - the ultimate file manager for Windows (and recently for Android too)
Total Commander (aka Windows Commander)
is the ultimate file manager for Windows (and recently for Android
too).
Who can use it?
The regular Windows user that used all
his life Windows Explorer will find Total Commander interface AT
LEAST awkward. The interface concept and user experience is totally
different in Total Commander. This doesn’t mean that Total
Commander is bad or poorly design or difficult to learn. It is just
different than Windows Explorer.
The regular user will require a day or
two to accommodate with the concept ( experienced users will have no
problem to gasp the new concept) but the efficiency improvement
totally worth it. I am a Total Commander use since 1998 and I never
ever (literally) used Windows Explorer again.
The concept
Total Commander solves an old design
flaw of Windows Explorer. So old that regular computer user won’t
even observe it anymore.
Many operations that you perform on
files involve copying or moving files from one place (folder) to
another. This is where Windows Explorer design fails: you work on two
folders, the folder from where you copy the file (source) and the
folder where you copy the file (destination), but Windows Explorer
has one single panel. The Microsoft solution is to browse and open
both folders and carefully drag and drop the files from source
to destination. I say carefully because it is easy to ‘un-carefully’
drop the files in the wrong folder. Obviously there are also other
methods but they are even more time consuming than this one. And when
you close the Explorer all that work invested into locating your
folders is gone. You have to start all over.
For a person that performs 1-2 file
operations per day it is not a big deal, but for an intermediate user
or a POWER user this is time consuming and error prone.
And, here is the time and place where
you install Total Commander. Total Commander brings the concept of
two parallel panels: it always shows on screen the source folder AND
the destination folder. Now all you have to do is to drag and drop
the files from one pane to the other (advanced users can user F5 and
F6 keys for copy/paste).
Total Commander will remember the last
used folders and ALSO the recent folders you navigated through. So,
if you worked on a folder few hours ago and you want to return to
that folder, you don’t have to browse the entire folder structure
to locate it again. Using the History (Alt+DownArrow) you are back
there with just one click.
The magic never stops
Total Commander has literary hundreds
of features that are not present in Windows Explorer: FTP,
compression support, fully customizable toolbar (that totally
replaces the Start menu), CRC control, Mime encoding, advanced multi
rename tool, advanced search tool, support for plugins (there are
also thousands of plugins for Total Commander), thumbnail view, quick
view, color coded file types, etc, etc, etc.
One of the useful functions we will investigate now is the File
Queue. With this function you can Queue a long list of file
operations for later execution and….
Disclaimer: I have no affiliation with Total Commander, except my affection for it :)

The best and most reliable 3GB hard drive
I need a 3GB internal harddrive. Looking through statistic data from BackBlaze, it seems that Seagate is the worst solution because of it HUGE failure rate. Yes the prices are good for this drive but you don't want a cheap drive that will fail after 2 years. Right?
The next brand with high failure rate is Western Digital.
Both Seagate and WesternDigital drive have price in the 100 euros range.
Toshiba has a much better failure rate.
But the winner is HGST. It has a significant higher price (126 euro) but totally worth it.

Embarcadero finally decided to fix SOME bugs in Delphi
In the new road map, Embarcadero finally decided to fix SOME bugs in Delphi.
It seems good news but hold your horses:
1. They not always keep their promise related to the road map.
2. There are not so many bugs
3. They won't do all the fixes at once, but until 2018
4. Until 2018 another 500 new bugs (AT LEAST) will be introduced
5. We have to pay (not 59 bucks but HARD money) to get that non-buggy version of Delphi.
And in the end, what the fuck are we so happy that Embarcadero is fixing some bugs? Is not a present, a gift from heavens! Those bugs SHOULD NOT BE THERE anyway!
So, thank you Embarcadero for finally thinking to fix some bugs and FUCK YOU.
PS: In the next road map maybe you will introduce an item likes "free updates".

Computer Virus that infects real-world DNA?
|
A computer code that is supposed to be able to infect DNA was found.
The corresponding article posted ~2.5 years, and some c++ codes. Citation:
So could there really be a computer virus
that infects DNA?Virus code is here: http://pastebin.com/NiQc55rr |
Answer:
It is NOT impossible for a computer virus to infect real DNA because 'artificial' life was already created from synthetic DNA by Craig Institute. Proof. That synthetic DNA coming from files that were generated in a computer. So, if the virus happens to be in the right computer, at the right time... But the chance is small.
However, in the next 10 years, that virus might be a real problem as every year it is more and more easy to create 'artificial' life.
IMPORTANT UPDATE!
I have found this comment in the C++ code:
// Encode own file into Craig Venter's DNA encoding languageIt looks like this virus was designed expressly for Craig Venter! So the chances for this virus to work (affect real-world DNA) are even more realistic!!
Validity of the code
Less experienced people doubt the validity of the code. However, no proof was brought to demonstrate that the code might fail (and why). Though, I haven't spend hours to read the code line by line and thoroughly analyze it, I did pick a look at it and it seem sound and valid. The fact that the author of the code targets a very specific organization (that "happens" to generate DNA from computer files) tells us that he knows what he is doing.
Purpose
As somebody already brought to our attention, there is no purpose in creating this virus. But this is totally irrelevant to the original question. Even if the DNA virus will destroy the host cell and even if it won't be able to replicate in real world (and it won't) it is irrelevant. If in the right computer, the computer virus will pass from the virtual world to the real world, and this is OP's question (I think).
Conclusion
The question asked was: "can a computer virus could infect DNA"?. The question is ambiguous. If it refers to the DNA of some living cell the answer is no. HOWEVER, if the question refers to a human-created cell, the answer is YES. Craing Venter creates DNA from computer ('fasta') files. If one of those files happens to be modified or 'infected' by the computer virus then the computer virus will have effect in real world (the DNA synthesized by Venter will contain the code injected by the computer virus).

Is (Embarcadero) Delphi's code optimized for speed? No? Here is how to optimize string speed
The short answer is a big NO!
No the long answer:
Today I needed a function that will wrap a string (a contiguous block of characters with no spaces) after 80 characters. Not only that I have found SysUtils.WrapText unsuitable (it can only wrap text IF the text contains spaces) but it is also terrible slow.
So I build my own function:
function WrapString(CONST s: string; RowLength: integer): string;
VAR i, Row: Integer;
Begin
Row:= 0;
Result:= '';
for i:= 1 TO Length(s) DO
begin
inc(Row);
Result:= Result+ s[i];
if Row >= RowLength then
begin
Result:= Result+ CRLF;
Row:= 0;
end;
end;
End;
Works nice but is is also slow. If you look into the code the problem is Result:= Result+ CRLF . It involves too many memory allocations.
Solution. The solution is to pre-allocate space for the result.
For this I created a new class TCStringBuilder:
TYPE
TCStringBuilder = class(TObject)
private
s: string;
CurBuffLen, BuffPos: Integer;
public
BuffSize: Integer;
constructor Create(aBuffSize: Integer= 10*Kb);
procedure AddChar(Ch: Char);
procedure AddEnter;
function AsText: string;
procedure Clear;
end;
IMPLEMENTATION
constructor TCStringBuilder.Create(aBuffSize: Integer= 10*Kb);
begin
BuffSize:= aBuffSize;
Clear;
end;
procedure TCStringBuilder.Clear;
begin
BuffPos:= 1;
CurBuffLen:= 0;
s:= '';
end;
function TCStringBuilder.AsText: string;

if BuffPos > CurBuffLen then
begin
SetLength(s, CurBuffLen+ BuffSize);
CurBuffLen:= Length(s)
end;
s[BuffPos]:= Ch;
Inc(BuffPos);
end;
procedure TCStringBuilder.AddEnter;
begin
if BuffPos+1 > CurBuffLen then { +1 because we enter two characters into the string instead of 1 }
begin
SetLength(s, CurBuffLen+ BuffSize);
CurBuffLen:= Length(s)
end;
s[BuffPos ]:= CR;
s[BuffPos+1]:= LF;
Inc(BuffPos, 2);
end;
Speed test:
I used a buffer of 10K. but the ideal buffer size would be the size of the input text plus 3%.
Please let me know if you can further improve this. Enjoy.

No the long answer:
Today I needed a function that will wrap a string (a contiguous block of characters with no spaces) after 80 characters. Not only that I have found SysUtils.WrapText unsuitable (it can only wrap text IF the text contains spaces) but it is also terrible slow.
So I build my own function:
function WrapString(CONST s: string; RowLength: integer): string;
VAR i, Row: Integer;
Begin
Row:= 0;
Result:= '';
for i:= 1 TO Length(s) DO
begin
inc(Row);
Result:= Result+ s[i];
if Row >= RowLength then
begin
Result:= Result+ CRLF;
Row:= 0;
end;
end;
End;
Works nice but is is also slow. If you look into the code the problem is Result:= Result+ CRLF . It involves too many memory allocations.
Solution. The solution is to pre-allocate space for the result.
For this I created a new class TCStringBuilder:
TYPE
TCStringBuilder = class(TObject)
private
s: string;
CurBuffLen, BuffPos: Integer;
public
BuffSize: Integer;
constructor Create(aBuffSize: Integer= 10*Kb);
procedure AddChar(Ch: Char);
procedure AddEnter;
function AsText: string;
procedure Clear;
end;
IMPLEMENTATION
constructor TCStringBuilder.Create(aBuffSize: Integer= 10*Kb);
begin
BuffSize:= aBuffSize;
Clear;
end;
procedure TCStringBuilder.Clear;
begin
BuffPos:= 1;
CurBuffLen:= 0;
s:= '';
end;
function TCStringBuilder.AsText: string;
begin
SetLength(s, BuffPos-1); { Cut down the prealocated buffer that we haven't used }
Result:= s;
end;
procedure TCStringBuilder.AddChar(Ch: Char);
begin
if BuffPos > CurBuffLen then
begin
SetLength(s, CurBuffLen+ BuffSize);
CurBuffLen:= Length(s)
end;
s[BuffPos]:= Ch;
Inc(BuffPos);
end;
procedure TCStringBuilder.AddEnter;
begin
if BuffPos+1 > CurBuffLen then { +1 because we enter two characters into the string instead of 1 }
begin
SetLength(s, CurBuffLen+ BuffSize);
CurBuffLen:= Length(s)
end;
s[BuffPos ]:= CR;
s[BuffPos+1]:= LF;
Inc(BuffPos, 2);
end;
Speed test:
- 500x loop
- test file: TesterForm.pas 2.7K
- wrap after 20 chars
- 484ms SysUtils.WrapText - unbuffered
- 5788ms WrapString - unbuffered (Result:= Result+ s[i])
- 31ms WrapString - buffered (using cStrBuilder)
I used a buffer of 10K. but the ideal buffer size would be the size of the input text plus 3%.
Please let me know if you can further improve this. Enjoy.

Animated desktop wallpaper
BioniX Wallpaper Animator v3 is ready for download. That is great about this new version is that it is (should be) able to paint the animation UNDER desktop icons.
However, since we cannot test it on all Windows operating systems we need some help. If you can run it on any of the following systems please let us know the results.
Download link:
www.bionixwallpaper.com/downloads/Animated Desktop Wallpaper
| Win 98 | Win 2K | Win Me | Win XP | Win Vista | Win 7 Aero | Win 7 Aero disabled | Win 8 | Win 10 |
| ? | ? | ? | ? | ? | OI | ? (should work) | ? | UI |
Legend:
UI = under icons
OI = over icons
? = unknown (not tested)
______________________________________
Plans for the next version:
- Support for AVI files
- Lower memory footprint

Three software programs that [used to] plague our computers: Acrobat, Java, Flash
There used to be three programs that really made our computer miserable. They were slow, bloated, intrusive and a lot of security holes opened with them when you installed.
Java - Probably Java is the nastiest of all
Until few years ago you could not browse some web sites because some derailed 'web developers' decided to put some 'cool' animations and menus on their web site that required Java, forcing YOU to install Java, this way.
Now, Java is a really intrusive mammoth that starts at computer start up, installs background services, make your browser literary crawl eating A LOT of memory and keep wasting your Internet bandwidth by checking and downloading updates. And boy, Java needs updates because every 3-4 days a MAJOR security hole was discovered! And every security hole in Java is a security hole in YOUR computer.
ACTUALLY, Java is so dangerous for your computer that "The U.S. Department of Homeland Security is advising people to temporarily disable the Java software on their computers to avoid potential attacks" floridatoday.com
It is so bad that Firefox won't even let you activate it.
I uninstalled Java maaaaany years ago from my computer and I vehemently refuse to install it. Not a single time! And many others like me have forced the web designer community not to use Java on their web site. Now probably less than 1 in 5000 web sites still have Java. So, you miss it a bit.
Acrobat Reader - Big deal for nothing
Adobe Acrobat Reader is basically a notepad. Its task should be to open a PDF file and show it on screen. It does this in such a bombastic way that 3 minutes later after Acrobat, but it is still crunching data, you forgot why you wanted to open that PDF anyway.
Same bubonic 'features' as Java: eats up lots or memory and disk space, invades you with background services, system tray icons and installs itself to run at computer start up.
Security wholes? Plenty.
Alternatives: Foxit PDF (once a decent and fast PDF viewer, now starting to step on exactly the same sick path as Acrobat Reader), Sumatra PDF. More about these Acrobat Reader alternatives.
And something else: Next time somebody sends you a PDF send him an email back and say "I politely request to send me the document as DOC or RTF. They are as good as PDF" then optionally sign: "Fuck you and best regards retard".
Adobe Flash Player
The Flash Player literary built and shaped the web as we know it. And this is not the web should be.
Firefox will also deactivate the Flash plugin when a MAJOR security whole is discovered. And boy, coming from Adobe, there are lots of those!
Alternatives: HTML5 - After all those years, the web community is finally coming to its senses trying to replace Flash with HTML 5, a major update of (too) old HTML. This change should have been done 25 years ago (which on Internet time-scale means 2 eons ago).
Most web sites already abandoned Flash and switched to HTML 5. So, it is not the time to turn off the Flash plugin in your browser and finally take a fresh breath of Flash-free Internet.
Also see "Flash is dying a death by 1,000 cuts, and that's a good thing" by TheGuardia.

Flash is so wrong in every possible way: difficult to program, terribly slow (and I mean it), bulky and unsafe. But Adobe really pushed money into it so they managed to shovel it down to our throats.

How to definitively turn off the Foxit updater
The updater in Foxit is really annoying. And even if you turn it off via the GUI the updater application will still run in background. This will delay the main Foxit window start up.
So, here is the trick: the the updater to think that it already checked for updates:
Open the registry (RegEdit) to:
\\\Registry\HKEY_CURRENT_USER\Software\Foxit Software\Foxit Reader 7.0\plugins\Updater\LastDay
Edit the LastDay key and put a higher number. In my case, instead of 0518357,1447384350 I put 0618357,1457384350.
If you are lazy, here is the REG file script (copy/paste the text below in a text file and change its extension to .REG then run the file):
_________________________
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Foxit Software\Foxit Reader 7.0\plugins\Updater]
"LastDay"="0618357,1457384350"
_________________________
Now Foxit will start almost instantaneously.
Firefox, suck it!

Adding Windows 10 to Windows' 7 boot menu
So, I installed Windows 10. I didn't liked it (at all) so I installed after that Windows 7 (on a different partition).
Now after 6 months I would like to see if Window 10 has improoved a bit, but Windows 7 won't show it in its boot menu. So, I cannot boot into Win 10 anymore.
Solution: bcdedit
Run the command prompt as administrator. Type bcdedit and it will show all installed operating systems (that it can recognize).
In my case (Win 7 primary, Win 10 'lost' partition) the output is this:
C:\>bcdedit
Windows Boot Manager
--------------------
identifier {bootmgr}
device partition=K:
description Windows 10
locale en-US
inherit {globalsettings}
default {current}
resumeobject {24334bef-7a25-11e5-866b-bca012dbdc37}
displayorder {current}
toolsdisplayorder {memdiag}
timeout 0
Windows Boot Loader
-------------------
identifier {current}
device partition=C:
path \Windows\system32\winload.exe
description Windows 7
locale en-US
inherit {bootloadersettings}
recoverysequence {24334bf1-7a25-11e5-866b-bca012dbdc37}
recoveryenabled Yes
osdevice partition=C:
systemroot \Windows
resumeobject {24334bef-7a25-11e5-866b-bca012dbdc37}
nx OptIn
As you can see the current OS is Windows 7 on C: partition.
First of all, make a backup copy of your boot entries, in case you fuck up something:
C:\>bcdedit /export c:\bdc_entry_backup
The operation completed successfully.
Then type the following command. It will add Win 10 (identified as 'bootmgr') at the list of available bootable OS's:
C:\>bcdedit /displayorder {current} {bootmgr}
Windows Boot Manager
--------------------
identifier {bootmgr}
device partition=K:

resumeobject {24334bef-7a25-11e5-866b-bca012dbdc37}
displayorder {current}
{bootmgr}
toolsdisplayorder {memdiag}
timeout 0
Windows Boot Loader
-------------------
identifier {current}
device partition=C:
path \Windows\system32\winload.exe
description Windows 7

inherit {bootloadersettings}
recoverysequence {24334bf1-7a25-11e5-866b-bca012dbdc37}

osdevice partition=C:

resumeobject {24334bef-7a25-11e5-866b-bca012dbdc37}

Done.
