Features


Revealing the Critical Role of Human Performance in Software
Knowing how people detect problems and work together to resolve them is essential for successful Internet-facing systems. The articles in this issue examine the role of human performance in achieving more resilient systems.
- David D. Woods and John Allspaw

Above the Line, Below the Line
Imagine a line running horizontally across an Internet-facing system. Above the line are the forces that shape, direct, and restore the technical artifacts that lie below that line. Understanding what goes on underneath is key to the system's resilience.
- Richard I. Cook, M.D.

Cognitive Work of Hypothesis Exploration during Anomaly Response
A primary function above the line of representation is coordination across multiple roles during service outages, particularly how people explore various hypotheses when responding to an incident.
- Marisa R. Grayson

Managing the Hidden Costs of Coordination
A service outage usually initiates an all-hands-on-deck approach, but smooth coordination of these multiple perspectives is important. Without it, cognitive costs can take a toll.
- Laura M.D. Maguire

Beyond the "Fix-it" Treadmill
Something goes wrong with your software. Chaos ensues until it is fixed. Then comes the postmortem focusing on what went wrong this time. There could be a more holistic approach that will prevent failures down the line.
- J. Paul Reed


Columns / Departments


COMMIT TO MEMORY
Securing the Boot Process
Like a relay race where one team member hands a baton to another team member, the boot sequence of a computer works better when all the parts know and trust each other. Standards and system transparency help achieve that trust.
- Jessie Frazelle

KODE VICIOUS
Master of Tickets
In the course of a day, Alice writes 1,000 lines of buggy code and Carol writes 100 lines of well-crafted code. Which should be rewarded? Quality or quantity? KV's answer won't surprise anyone.
- George Neville-Neil

THE MORNING PAPER
The Way We Think About Data
Consider these ideas when it comes to data: First, interpretable models may offer benefits not found in a black-box model. Second, local-first software may combine the advantages of cloud apps with native, installed apps.
- Adrian Colyer

FAQ


Why is the text so small?

The maximum text size on newer, high-resolution (more than 2 megapixel) device screens may be too small for some individuals to read easily. Use the links above to preview the first six pages of an issue. If you find the text too small, you may prefer to use the browser-based version of the app until this problem is resolved.


I'm having trouble viewing the browser version of the app

Make sure you have the Flash plugin and JavaScript enabled. Try turning off any ad-blocking software. Make sure you're using one of the more recent browser releases. We suggest the minimums of Chrome 23, Firefox 19, IE 10, and Safari 5.


How do I log in to the browser version?

The user session for the app is not tied to myACM so you must log in separately.

The login screen only appears after you have advanced beyond the 6-page preview. When in the preview, click any of the links and you should see a prompt to log in.


How do I get a PDF of the issue?

We offer PDF versions of all articles. If you go to an individual article on the site, you should see a PDF icon in the upper right e.g. http://queue.acm.org/detail.cfm?id=2844732

Or, if you go to the table of contents for an issue in the Digital Library, you should see links to download PDFs for all articles in the issue e.g. http://dl.acm.org/citation.cfm?id=2838344&preflayout=flat

Or, if you log in to the browser version of the app, you should see a download icon in the upper right that will download the full PDF of the entire issue https://mydigitalpublication.com/publication?m=38068&l=1

Or, again in the browser version of the app, click the lower-right 'More' icon ("...") to reveal additional options, including a print function.

An additional option is to click the 'Contents' icon in the upper right (looks like the old Windows logo) which will pull up links to all articles without formatting or images. You may need to click the screen to expand the top and bottom menus to reveal the icons.


How do change my subscription?

ACM members should contact ACM (https://myacm.acm.org/dashboard.cfm) to update their passwords, renew subscriptions, etc.

iOS users should contact Apple to update their passwords, renew subscriptions, etc.

For all subscriptions and issue purchases for the Android and browser-version of the app, contact [email protected].


How do I get the navigation menu/panels to reappear?

Just tap the screen in an area that is not a link.

For the browser version, you may need to right-click. (ctrl-click on Mac).


Explain the members. non-members, subscription thing again?

ACM professional members (not student members, not users with plain web accounts) get full access to acmqueue on iOS, Android, or as a browser "app" (for lack of a better term). They simply login using their member account login.

Everyone else (non-members) have the choice of (a) joining the ACM and getting full access to acmqueue (among other things), (b) buying an annual subscription to the magazine as an iOS app, Android app, or browser app, or (c) buying a single issue, again as an app on their phone or browser.


Certain things look odd in Opera

The Opera browser is not supported, sorry. We only saw one CSS bug in Opera on Android, but otherwise it should still look the same as most other platforms.


I just found out my subscription has expired, why wasn't I notified?

ACM members's accounts are handled through the ACM https://myacm.acm.org/dashboard.cfm

iOS subscribers should be getting notification from Apple.

For Android subscribers and browser version subscribers there is currently no mechanism to remind them of subscription cancelations. Sorry.


I have a student ACM membership. Why can't I log in?

Unlimited access to acmqueue is granted to professional memberships only.


I have a subscription to the app. Can I use that to log in to the browser version?

No, subscription to the iOS app, Android app, and browser version do not permit access to either of the other versions.
