I have a DUNLOP SPORT DS 26 Bike. Here is a similar bike:    I would like to add hydraulic disc brakes at both front and rear.  But the frame or forks do not have anywhere I can mount the Calipers, and the wheels I have are regular ones.   How can I convert my regular wheels to adapt to the Disc brake wheels, and how can I mount the calipers to the frame?
I just bought a used  and it comes with regular rim brakes. I'm perfectly happy with them so far, but have been wondering if disc brakes would come handy when it rains.  What is involved in converting a bike from rim brakes to disc brakes (mechanical or hydraulic)?   Is this something that is feasible, or am I better off buying another bike that already has disc brakes?
Varying behavior for possible loss of precision What programming languages can I use in Blender? What version of Python does Blender use and are other languages available? Also, does Python work the same in Blender as when you write console applications or when working with Pygame or are there any differences? If so, what are the main differences? Autofilling fields based on another field Your last flag was declined - no it wasn't I went to flag something, and in the flag dialog I got the message  "Your last flag was declined - please review it before flagging this post!"    That's all well and good, but when I went to review my flags, the statement is not accurate.  My last 5 flags were all marked 'helpful'.  The 6th down the list is marked 'declined', but that wasn't my last flag.  The message should probably be modified to correspond to the actual condition that triggers it.  Perhaps it should say     One of your flags was recently declined - please review it before flagging this post!   I'm going to guess that this message is triggered if, of all the flags of mine that have been handled by a moderator, the one that was most recently handled was declined. This isn't necessarily the last flag that I raised (the one I raised most recently), as moderators might handle them in a different order than I raised them, and it's not necessarily the flag at the top of the list.  Thus, calling it my "last" flag seems like it could cause confusion.  Yes, I realize this is extremely minor. Does $\int_{ - 1}^1 {\frac{1}{x}dx} = 0 \text { or } \infty $?

The thing is, that titletoc can do the same thing in a easier way, less one.  \titlecontents*{subsection}[5.4em] {\small} {\thecontentslabel~ } {} {} [.~\textbullet\ ] [.]   this part does the subsection as a paragraph (with section number and without page number). I have realized that the problem is the pseudo-code used by tocloft for the entries in the TOC  {\cftXfont {\cftXpresnum SNUM\cftXaftersnum\hfil} \cftXaftersnumb TITLE}% {\cftXleader}{\cftXpagefont PAGE}\cftXafterpnum\par   I mean, the last command \par make impossible to leave two subsection entries in the same textline. Any idea? Another interesting solution is with etoolbox, some examples with that package are awesome, but it's not on my hands.  This is a MWE:  \documentclass{book}  \usepackage{titletoc} \titlecontents*{subsection}[5.4em]{\small} {\thecontentslabel~ }{}{}[.~\textbullet\ ][.]  \begin{document}  \tableofcontents  \chapter{Test Chapter 1} \section{Test Section 1.1} \subsection{First Test Subsection} \subsection{Second Test Subsection} \subsection{Third Test Subsection} \subsection{Fourth Test Subsection} \section{Test Section 1.2} \subsection{First Test Subsection} \subsection{Second Test Subsection}  \chapter{Test Chapter 2} \section{Test Section 2.1} \subsection{First Test Subsection} \subsection{Second Test Subsection} \subsection{Third Test Subsection} \subsection{Fourth Test Subsection} \section{Test Section 2.2} \subsection{First Test Subsection} \subsection{Second Test Subsection}  \end{document} How should I install HPLIP binary/proprietary plugin/driver for my HP printer or printer+scanner? Let's assume that one has some modern HP printer and/or scanner which is  supported by HPLIP package from official repository.

What is the difference between a gameplay programmer and a game designer/developer? Can I convert a string representing a boolean value (e.g., 'true', 'false') into a intrinsic type in JavaScript?  I have a hidden form in HTML that is updated based upon a user's selection within a list. This form contains some fields which represent boolean values and are dynamically populated with an intrinsic boolean value. However, once this value is placed into the hidden input field it becomes a string.  The only way I could find to determine the field's boolean value, once it was converted into a string, was to depend upon the literal value of its string representation.  var myValue = document.myForm.IS_TRUE.value; var isTrueSet = myValue == 'true';   Is there a better way to accomplish this?
