And finally …

Contact MG

You can reach me by email. I invite questions, corrections, constructive criticism and complaints (polite ones) with the following caveats:

  1. I do have a day job (surprising isn’t it), I will respond to all polite emails but not necessarily instantly.

  2. I can’t offer detailed engineering advice about specific problems (e.g. why does that valve blow all the fuses when I try to open it), but I will offer pearls of wisdom about less specific software issues.

  3. I don’t know anything about car engines or kettles so please don’t ask.

  4. For the more emotionally tainted, my dogs, Hector and Henry, are Salukis and while it may be off topic I have a soft spot for them and I may be willing to discuss them if pushed.

  5. If your email comes down to “I think your website’s rubbish, I won’t pay for it, but I do want to shout at you for a while about your outrageous shortcomings” then please, there is no need to trouble yourself; you’ve already said everything by not paying.

So if you’re happy with that, you can reach me here:

mg@practicalseries.com.

I’ve included the full details of how I store and manage emails in the privacy and personal data section below:

Acknowledgements

Thanks to everyone who has paid for this website. Your contributions are appreciated.

Thanks to the dogs: Hector (left) and Henry (right) their advice was invaluable.

Most of the images in the website are my own or of my creation (which probably explains the poor quality).

The exceptions are the photographs of Capital magazine in Figure 3.1; these images are reproduced courtesy of the Herb Lubalin Study Center at The Cooper Union (41 Cooper Square, Room LL119, New York) — lubalincenter.cooper.edu.

In Figure 3.4, the three images of Chester are courtesy of Michael D. Beckwith and the image of the Houses of Parliament is courtesy of Samel Zeller. The image of the metal type face (Figure 3.9) is by Hannes Wolf. All these images are via the unsplash website and are used under the creative common zero licence (reproduce below).

The fonts used were created by Mr Matthew Butterick and are Equity (serif), Concourse (sans serif) and Triplicate (monospace); I refer to them collectively on the website as the Equity fonts. If you want to use them you can buy them here.

The downloadable version of the website uses the open source fonts: PT Serif, Source Sans Pro, PT Mono, Carrois Gothic SC and Andada Regular SC. These are available from.font squirrel.

All of these fonts with the exception of PT Serif are available under the sil open font licence. PT Serif is available under the paratype pt sans free font  licence (both are reproduce below).

The website uses various third-party software and files, I hope I’ve adequately and correctly made notification of them on the website and in the source code — I do so again here:

Preamble

The goals of the Open Font License (OFL) are to stimulate worldwide development of collaborative font projects, to support the font creation efforts of academic and linguistic communities, and to provide a free and open framework in which fonts may be shared and improved in partnership with others.

The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives.

Definitions

“Font Software” refers to the set of files released by the Copyright Holder(s) under this license and clearly marked as such. This may include source files, build scripts and documentation.

“Reserved Font Name” refers to any names specified as such after the copyright statement(s).

“Original Version” refers to the collection of Font Software components as distributed by the Copyright Holder(s).

“Modified Version” refers to any derivative made by adding to, deleting, or substituting — in part or in whole — any of the components of the Original Version, by changing formats or by porting the Font Software to a new environment.

“Author” refers to any designer, engineer, programmer, technical writer or other person who contributed to the Font Software.

Permission & conditions

Permission is hereby granted, free of charge, to any person obtaining a copy of the Font Software, to use, study, copy, merge, embed, modify, redistribute, and sell modified and unmodified copies of the Font Software, subject to the following conditions:

  1. Neither the Font Software nor any of its individual components, in Original or Modified Versions, may be sold by itself.
  2. Original or Modified Versions of the Font Software may be bundled, redistributed and/or sold with any software, provided that each copy contains the above copyright notice and this license. These can be included either as stand-alone text files, human-readable headers or in the appropriate machine-readable metadata fields within text or binary files as long as those fields can be easily viewed by the user.
  3. No Modified Version of the Font Software may use the Reserved Font Name(s) unless explicit written permission is granted by the corresponding Copyright Holder. This restriction only applies to the primary font name as presented to the users.
  4. The name(s) of the Copyright Holder(s) or the Author(s) of the Font Software shall not be used to promote, endorse or advertise any Modified Version, except to acknowledge the contribution(s) of the Copyright Holder(s) and the Author(s) or with their explicit written permission.
  5. The Font Software, modified or unmodified, in part or in whole, must be distributed entirely under this license, and must not be distributed under any other license. The requirement for fonts to remain under this license does not apply to any document created using the Font Software.

Termination

This license becomes null and void if any of the above conditions are not met.

DISCLAIMER

The font software is provided “as is”, without warranty of any kind, express or implied, including but not limited to any warranties of merchantability, fitness for a particular purpose and non-infringement of copyright, patent, trademark, or other right. In no event shall the copyright holder be liable for any claim, damages or other liability, including any general, special, indirect, incidental, or consequential damages, whether in an action of contract, tort or otherwise, arising from, out of the use or inability to use the font software or from other dealings in the font software.

Legal

© 2016 Michael Gledhill. All rights reserved.

The website framework: its format, structure and source code, I make available to all who wish to use it. The text and images within the website may not be publicly reproduced without my written permission. In the unlikely event that you do wish to do so, please send requests to me at: mg@practicalseries.com.

I have not been compensated to recommend any of the software, websites or products mentioned on these pages or used in the production of this website.

  • I reference Mr Matthew Butterick’s Practical Typography website on several occasions within these pages. Despite the name, I have no connection with Practical Typography (although I do recommend it) and it is not part of the Practical Series of Publications — the name is purely coincidental — I had already registered practicalseries.com when I became aware of Practical Typography (in fact in the course of researching web layouts and typography for this website).

Privacy & cookies

This is a big thing now in Europe and in England: gdpr (General Data Protection Regulation); it means I have to be very careful with any data I collect about people. I also have to explain why I want the data and what I’m going to do with it. So here goes:

Cookies

The only cookies I use on this site are those needed for google analytics and PayPal I use Goole Analytics to help analyse how visitors use the site. It works by installing cookies on your computer. Cookies are small text files that are used to collect standard internet log data (time of visit, type of browser, operating system &c.) and visitor behaviour information (referring sites, landing page, links to other sites that have been clicked &c.). It collects this data in an anonymous form. Note the deliberate emphasis on anonymous, no personally identifiable information†1 is collected, the type of information collected by Google Analytics is given on their help page under data collected by google analytics.

The anonymous information generated by Google Analytics cookies about your use of this website is transmitted to Google — not to me. This information is processed to compile statistical reports on website activity (for this site only). I use these reports to evaluate the aggregate visitor usage; I do this so that I can optimise the website content, and hopefully, make it better (if I’m being honest, I also like to know how many people visit, it make me feel better if the number goes up).

The PayPal cookie is used for the PayPal checkout process (you have to give PayPal some information if you want to make a donation).

In summary, you can browse this site with complete anonymity.

†1 By default Google Analytics collects the IP address of the website user. This is deemed personally identifiable information under GDPR (i.e. it is not considered to be anonymous), it is possible to stop Google Analytics doing this (by making it anonymise the IP address data, this is done by masking the last three digits of the address, see here for how to activate this option) and this is what I have done on this site.
I am not collecting IP addresses via Google Analytics.

Privacy and personal data

This website does not ask for, nor does it collect, personal data. There is no contact-me form that asks for names, addresses, email details or phone numbers &c. Neither are there any user logons or other such forms of identification.

People can email me if they want to, but that is their choice (I’ve given my email address in a previous section) and I will respond as an individual to any emails I receive.

Where people do email me, I will not pass on any of their details to anyone else (even when they are rude to me). I respond directly to the sender and do not copy, forward or otherwise redistribute their emails with anyone else.

I delete all emails three months after the email conversation is complete (i.e. if you haven’t emailed me for three months I delete all the emails I’ve received from you and any replies I’ve sent to you).

I do not reply to abusive emails (never argue with a stranger on the internet) and these I delete straight away.

Where someone has asked a common or pertinent question, I may store the question itself and my response (these are copied to an offline Word FAQ sheet — what engineers call a technical query sheet), but I do not store any of the questioner’s details (just the question and answer in an anonymous text based format).

I also receive the email addresses and some contact details of those people who make a donation to this website. This information is provided to me by paypal — they tell me who has made the donation.

If the donation is for £5 or more, I keep certain information about that individual in a secure offline database. I store precisely:

  • Name

  • Email address

  • Donation amount

  • Date of the donation

I do this purely for the purpose of sending those people a link to the downloadable pdf version of this website (I make this freely available to all who donate £5 or more).

I keep this information so that I can send a link for each new revision of the pdf when such revisions are issued (typically once a year). I.e. I make the pdfs available in perpetuity.

I do not share this information with anyone.

I do not send marketing or unsolicited emails of any kind (I do not have a mailing list or anything like that).

Anyone wishing to have their details deleted need only ask. You can contact me at the following email address: mg@practicalseries.com.
