The first West Coast Computer Faire in 1977 was a landmark event in the birth of the personal computer industry. Held April 15-17 in San Francisco, the show introduced kit and assembled computers to a general public audience of more than 10,000. WCC Faire was a key turning point in the evolution of computers from geeky curiosities into mainstream consumer products. The Apple II and Commodore PET both debuted at the event, along with hundreds of other exhibits of homebrew and commercial computer systems.

Here’s an excerpt from a first-hand account of WCC Faire 1977 by David H. Ahl:
Ahl: You’ve got essentially what you call a black-box computer. Self-contained. You don’t really have to know anything except how to hit a switch. What type of market are you aiming at? Somebody that wants to do programming, play games, or what? Anything specific?
Markkula: All of the above and more. We really want to be the computer company, not the small-business computer company or something else – just the personal computer company! So that’s the reason you see a molded plastic case, BASIC in ROM, and so on. In fact we want to extend the whole concept to make it even easier to use.
Ahl: What’s the MPU chip in the Apple II?
Markkula: The 6502. It’s the most efficient chip for what we’re trying to do.
Ahl: What would a complete Apple II system require in terms of memory for the beginner?
Markkula: 4K is more than adequate. Remember the 4K that comes with a standard minimum system is all user space because the BASIC is in ROM. So almost all of the 4K RAM is available for programming and data.
Ahl: What would a system of that configuration cost?
Ahl: Is that assembled?
Markkula: Assembled, tested, complete with two game paddles and a complete carrying case so you can carry it around – all the cords and manuals and operation information.
Ahl: When do you start making deliveries?
The entire Big Mess o’ Wires site should now be usable via the encrypted https protocol. I had some trouble with this a year ago, when I unintentionally enabled https for the blog and discovered that lots of things broke. At the time, I wasn’t ready to make the effort to fix it all, so I implemented a security-unfriendly solution of redirecting all https requests to plain unencrypted http instead. As of today that’s no longer necessary, which is good news.
The BMOW store has always been https-only, but I never thought the blog section needed https. After all, there are no passwords or financial data or other secrets to protect here. The trouble with enabling https for the blog is the zillions of hard-coded references to http://www.bigmessowires.com in the text of old posts, image URLs, forms, and elsewhere. Http elements in an https page cause the browser to give security warnings, and some features like forms just plain don’t work. Fixing this was much less trouble than I’d feared – it only took one careful search-and-replace operation on the database to fix most of them. Yes I have backups, but I still quadruple-checked my search parameters before bulk-modifying 10+ years of posts.
Why is encrypted https useful for browsing public information, like the contents of the BMOW blog? Depending on your level of paranoia, it’s not. However, if you’re especially concerned about privacy, browsing the blog using https instead of http will provide some extra protection. It will prevent snoopers from seeing exactly what content you’re viewing on the BMOW site, or what you posted in the content forms. They’ll still be able to see that you interacted with bigmessowires.com, but no details about what you did there.
Https also provides more confidence that the content you’re viewing is the same content that the server sent you. With an unencrypted connection, a man-in-the-middle (your ISP, for example) could modify the pages you’re viewing on the fly, inserting extra advertisements or tracking elements or malware. I’m not certain this protection is completely guaranteed, however. While I’m no expert, I’ve read about SSL interception proxies that sit in the middle of an https connection, while making both ends think they’re communicating directly with the other end. Nevertheless, using https for all your web browsing should greatly reduce the risk of this type of tampering.Read 2 comments and join the conversation
Frosted Ice cases for Floppy Emu are back in stock at the BMOW store, and I took the opportunity to make a time lapse video of the case packing process. Where does all the time go? Last week’s video featured the behind-the-scenes order fulfillment process, in which pre-bagged case kits were already prepared. Today’s video shows where those came from.
The plastic case parts come pre-made on large laser-cut sheets from a third party, with enough parts for seven cases per sheet. The parts must be pulled out, sorted, and placed into individual bags. Fastener hardware is added to each bag, before it’s sealed and ready for sale. Extra light pipes from clear sheets are saved to be reused with opaque sheets for Snow White cases. It’s one more unglamorous task that consumes surprising amounts of time.

This time-lapse video shows all the steps needed to fill six typical BMOW hardware orders. Running an electronics hobby business can be lots of fun, but can also be highly time-consuming. If your operation is too small to support other employees, you’ll spend the bulk of your time prepping product and stuffing boxes instead of developing new tech.
What exactly is involved in filling somebody’s order for a new gadget? Even when the products involved are pre-assembled and “ready to ship”, there’s still work to do. Starting from the beginning of the video, here’s the chronology:
0 minutes – Download the recent order data, and print packing lists. Make a little pile on the floor for each outgoing order. Add quickstart guides and instruction sheets to the piles, as needed.
4 minutes – Pull the LCD off each Floppy Emu, and tighten its mounting tabs. Adjust the LCD contrast to something reasonable – the exact level varies from one LCD to the next. Flash the newest Emu firmware to the board.
12 minutes – Grab a set of DB19 adapters and a bundle of ribbon cables. Remove the DB19 adapters from their anti-static bags, and put the Emu boards in the bags. Connect the cable assemblies, fold them up neatly, and add everything to the growing piles on the floor.
16 minutes – Cut the SD memory cards from their cardboard packaging. Copy the master image to the cards, using a stand-alone SD duplicator. Add to the piles. Also start wrapping some items, during the copying dead time.
22 minutes – Add enclosures to the piles. The enclosure parts were bagged previously, in a separate time-consuming process of punching and sorting parts from laser-cut sheets.
23 minutes – Pack fragile items in bubble wrap. Fold up the papers.
28 minutes – Buy necessary postage. Custom software determines what postage type and amount is needed for each shipment.
29 minutes – Why is this Japanese address getting rejected by the address validator? Manually rewrite the address, twice.
33 minutes – Print the postage.
36 minutes – Pack the finished piles into boxes or padded envelopes. Seal them and affix the postage.
42 minutes – Put some tiny spare parts into an envelope. Hand-address the envelope to the customer.
46 minutes – Collect all the outgoing mail into a bag, and clean up the leftover scraps.
The entire process in the video takes 47 minutes, which excludes the time needed to deliver the packages to the post office. All tolled, it’s about an hour of time.
If you’ve ever run a small hobby business, you’re probably nodding your head at all of this. If you’re thinking about turning your hobby creations into a small business, I don’t want to discourage you, but the reality is that selling physical goods takes time. It’s fun tinkering with interesting electronics, and talking with like-minded people, but the mundane work of getting parts and filling orders consumes most of the time you can devote to the business. Developing iPhone apps is probably a smarter way to earn extra dollars!
Bonus game: Search the video to see how many geeky electronics items you can identify hidden around the room.Read 4 comments and join the conversation
A blacklist can be a powerful tool for identifying spam email senders, but if you find yourself unfairly blacklisted, it’s maddening. Since sometime last September, roughly 30% of all my outbound customer-related emails have been rejected by the destination email server. Most of these are order confirmations or shipment notifications, and when they go missing, I get lots of frustrated inquiries from customers wondering why they never heard anything after placing an order. The rejections from the destination email server typically look like this:
550-“JunkMail rejected – pdx1-shared-relay1.dreamhost.com
[18.104.22.168]:40663 550-is in an RBL on rbl.unified-contact.com, see

X-Postfix-Sender: rfc822; email@example.com
Arrival-Date: Mon, 9 Jan 2017 14:07:03 -0800 (PST)
The exact message varies, but it usually mentions being on a realtime blacklist, or simply says my email was suspended, blocked, or refused. Other mail hosts such as Yahoo and Outlook.com take a passive-aggressive approach, and just drop the connection when I try to send email to one of their customers:

I haven’t tested it thoroughly enough to be certain, but I believe the problem only occurs for auto-generated emails from the BMOW store, and not for customer support emails that I compose manually – even though both are sent through mail.bigmessowires.com to the same destination email server.
Identifying a Spammer
So how did I get on these blacklists? It turns out it has nothing to do with the content of my own emails, but is entirely due to my web and email hosting provider, DreamHost. They offer cheap and convenient hosting, which doubtless attracts a few people using their servers for evil purposes, sending spam. This causes the DreamHost email relay server to be placed on multiple blacklists, affecting all the other DreamHost customers who share that relay. While I only started to notice the problem last fall, this forum discussion reveals it’s been happening since at least 2013.
I’ve contacted DreamHost customer support several times about this issue. At first, they said the problem was resolved, and they had confirmed with all major blacklist providers that the block on the affected relay had been removed. And the situation did seem to improve temporarily, though it was never completely resolved. When the blocks grew more frequent again, I contacted DreamHost a second time on December 8 and received this reply:
sending mail, and it is used by hundreds of individual users. …
Over the last week, we have experienced a surge of compromised customer
SMTP users that were being used to send out malicious emails. Although we
monitor outgoing mail traffic closely and were able to stop these
compromised domains quickly, enough email managed to get through to cause
several blocklist providers to block a percentage of our email servers.
Many providers have already delisted the IP, but some holdouts do remain,
with whom we are actively working to fully resolve the block. If these
rejection notices continue for more than about 48 hours, please don’t
hesitate to let us know.
Sorry, we’re working on it, everything will be back to normal soon. But unfortunately it didn’t go back to normal, and a few weeks later I contacted them a third time. I received a detailed technical reply that focused primarily on a specific provider named 1&1. Apparently 1&1 doesn’t like the way DreamHost mail servers identify themselves when communicating – an issue related to reverse lookups involving a load balancer – so the DreamHost servers get blacklisted regardless of the content of the email. It wasn’t clear if a solution to this identification problem was imminent, or even possible. Customer support also mentioned that it can take up to a month to be removed from a blacklist:
Backscatter, and LashBack), provide a paid “express” delisting, while
imposing an unreasonable long wait for manual or automated delisting (In
the case of LashBack, they autodelist after a month). As this amounts to
extortion, it is Dreamhost policy not to utilize paid delisting services
(they provide no added benefit to customers, encourage “bad behavior”,
and are generally a sign of an overzealous mail system administrator).
It seems unlikely that 1&1 is the only remaining problem, since my emails to domains like Yahoo and Outlook.com are also being rejected. As far as I’m aware, these are unaffiliated with 1&1.
Getting Past the Block
DreamHost’s responses have all been apologetic, giving the impression that service should be back to normal soon. Maybe I should just be patient and wait, but it’s been three more weeks since that last customer support response, and the situation hasn’t improved. The 2013 forum discussion complaining of this same problem proves it’s not a one-time occurrence. And I received no reply to my most recent CS inquiry asking for a status update or work-around suggestions.
Maybe I should move bigmessowires.com to a Virtual Private Server with a unique IP, instead of relying on shared hosting. I’d consider that if I were confident it would fix the problem, but that’s exactly what the 2013 forum poster tried and complained didn’t work. It’s unclear to me whether that was his fault or DreamHost’s. Even if I knew it would solve the email problem, I’m a little reluctant to jump to a VPS due to the extra server admin hassles it would involve. I really like the convenience of shared hosting, where I focus entirely on the content and leave the server administration to someone else.
Perhaps it’s time to migrate the whole site to another hosting provider, but I don’t think so. I expect most other shared hosting providers will have similar issues, and possibly worse service. During the 13 years I’ve been with DreamHost, their customer support has been excellent. This email blacklist problem is the first time I’ve felt let down by their service.
The best option I’ve come up with is to move BMOW’s email functions to a more “trusted” provider, while leaving the web site and store with DreamHost. That would mean monkeying with DNS entries to relocate mail.bigmessowires.com and a few others, or else simply using a different domain like bmowmail.com for all email. Zoho looks like it might fit my needs, and it would be free for my level of usage. I need to dig into the technical details to confirm it would do what I think it does, and would actually solve the blacklist problem.
If you’ve ever dealt with an email blacklist dilemma, or have any other suggestions on how I might resolve this one, please leave your feedback in the comments. Thanks!Read 11 comments and join the conversation
Good news for BMOW fans from outside the United States: international shipping costs for most orders should now be substantially lower than before. I wrote about the pain of international shipping costs a few weeks ago, and ever since then it’s been on my mind. Since about half of all BMOW customers are outside the US, I want to do everything I can to make their shopping easy and inexpensive, and I’m glad I’ve finally been able to address the shipping issue.
So how did I do it? The weight-based shipping rates haven’t changed, and those are set by the US Postal Service. Since I can’t lower the postage cost for a given weight, I instead focused on reducing the weight for a given item by using ultra-light packaging material whenever possible. Instead of shipping international orders in bulky and heavy cardboard boxes, many orders will now ship in padded mailing envelopes with a triple-layer of bubble wrap inside to protect the contents. I’ve tested this to several different destination countries, and it’s proven to protect the contents just as well as a box. Lower weight means lower shipping costs, so everybody wins.
International shipping costs for typical orders will be 40% cheaper thanks to this change. Most orders will now fall under the critical 0.5 pound threshold where higher postage rates take effect. Overseas customers will see typical shipping costs reduced from $24.25 to $15.25, and Canadian customers will see a reduction from $17.00 to $11.00. Hooray!Read 2 comments and join the conversation
