The new guidelines underscore the fact that a vaccine is highly unlikely before the election.

Over 200,000 people have died in the United States, a staggering toll that comes as the virus spreads to places that were spared early on.

Warning that this election is an “extremely dangerous moment” for the country, he said in an interview that he would aggressively push to try to stop President Trump from delegitimizing the vote.

The woman was found with a loaded gun and knife when she was arrested on Sunday while trying to enter the United States from Canada.

Olivia Troye, the latest Republican to leave the administration and speak out against President Trump, called the statements seeking to undermine her credibility “a bald faced lie.”

The Joomla Project is pleased to announce the availability of the Joomla 4.0 Beta 4 release, and the second Alpha of Joomla 3.10.

With Joomla 4.0 beta being released a few weeks ago, we enter into a phase of stabilization. Joomla! 4.0 is feature complete, that means, no new features are going to be added to Joomla 4.0. The focus is on fixing the last bugs to get Joomla! 4.0 out as soon as possible. But what will happen until the release and afterwards? Obviously we don’t want to stop new feature development, which is why we would like to refine our development strategy for upcoming versions. Whenever we start the work on a new minor version, we plan to define the subsequent two minor releases This results in a more reliable release cycle and a more consistent road map.

If you want to make a single attribute read-only on a class, the easiest way to do it is to make a property representing your attribute. The Problem Let's say we have a Thing class with value and color attributes: class Thing: def __init__(self, value, color): self.value = value self.color = color We want the color to be changeable after the class has been made: >>> thing = Thing(4, 'red') >>> thing.color 'red' >>> thing.color = 'blue' >>> thing.color 'blue' But we don't want the value to be changeable (it is right now!). The Solution We could try to override the __setattr__ method, which is called whenever any attribute is assigned and then do something special when value is assigned... but that's more complicated than we need for this scenario. The simplest way to make one attribute immutable is to make a property for that attribute: class Thing: def __init__(self, value, color): self._value = value self.color = color @property def value(self): return self._value That property decorator makes it so that whenever we attempt to access the value attribute, that value method we defined will be called and its return value will be given to us: >>> thing = Thing(4, 'red') >>> thing.value 4 We've made a getter for this property but not a setter (see the links at the bottom of this page for more on properties) so we won't be able to set this property: >>> thing = Thing(4, 'red') >>> thing.value = 5 Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: can't set attribute That's exactly the behavior we're looking for! ? Properties don't store data: they call functions Note that we're not actually storing a value attribute on our Thing class above... we're storing a _value attribute instead. The reason is that if instead of saying self._value = value, we said self.value = value in our initializer, the setter for our property would be called, which doesn't exist. Accessing or assigning to self.value will always go through our property getter/setter now. We need to actually store our data somewhere and we've chosen to put an _ before the attribute we're storing to note that it's an internal implementation detail of our class which shouldn't be touched from the outside. It still can be changed from the outside (no one's stopping us from doing that) but if you ever see code that reaches into another class and reads or writes to _-prefixed attributes, you should squint at it because something weird is going on. ? >>> thing = Thing(4, 'red') >>> thing._value = 5 >>> thing.value 5 Related Resources Another short demo of the property decorator A screencast on properties An example of when not to use a property More on properties

Earlier this year, Noel O'Boyle wrote the essay Python patterns for processing large SDF files and Richard Apodaca wrote Reading Large SDfiles in Rust. In this essay I'll show some examples of using chemfp's text toolkit API to extract non-chemical/near-chemical data from SDF records. The next essay will be a short one on read_sdf_ids_and_values(), followed by one which is more chemisty focused. You can follow along yourself by installing chemfp (under the Base License Agreement) using: python -m pip install chemfp -i https://chemfp.com/packages/ chemfp's text toolkit API You likely know chemfp is a package for high-performance cheminformatics fingerprint similarity search. What you probably don't know is the Python API includes a text toolkit API, with functions to read SMILES and SD files. It can be used to, for examples: add tag data to an input SDF record but keep everything else unchanged. This preserves data which might be lost by converting to then from a chemical toolkit molecule. synchronize operations between multiple toolkits; For example, consider a hybrid fingerprint using both OEChem and RDKit. The individual RDKit and OEChem SDF readers may get out of synch when on toolkit can't parse a record which the other can. In that case, use the text toolkit to read the records then pass the record to the chemistry toolkit. extract tags from an SD file. Chemfp's sdf2fps uses the text toolkit to get the id and the tag value which contains the fingerprint. The low-level SDF record iterators are: read_sdf_records() - iterate over the records in an SD file read_sdf_records_from_string() - the same, but from a string read_sdf_ids_and_records() - iterate over the (id, record string) pairs from an SD file read_sdf_ids_and_records_from_string() - the same, but from a string read_sdf_ids_and_values() - iterator over the (id, value) pairs from an SD file read_sdf_ids_and_values_from_string() - the same, but from a string Comment lines in ChEBI Last week in my SDF record walkthrough I pointed out that ChEBI record CHEBI:76065 is a rare example of an SDF record with a non-empty comment line. (That's the third line of the record.) I found it using something like this long one-liner using ChEBI_complete.sdf.gz which I downloaded on 21 Sept. 2020: % python -c 'from chemfp import text_toolkit as T;print(*sorted(set(record.splitlines()[2] for record in T.read_sdf_records("ChEBI_complete.sdf.gz"))), sep="\n")' b'' b' ' b' ' b' ' b' ' b' ' b' ' b' ' b' ' b' ' b'Mrv1722008032014042D ' b'Structure generated using tools available at www.lipidmaps.org' b'null' The reason for the b'' in the output because chemfp parse the records as byte strings, not Unicode, for performance reasons. (In addition, the SD file format does not specify a character encoding, and I've seen Latin-1 encoded files which cannot be read as UTF-8.) The print function, when given a byte string, encodes it with the leading b' and trailing '. It would also escape any non-ASCII bytes, but these comments are all ASCII. This one-liner can be written as a small program which is likely easier to read. However, it's very idomatic so I'll explain it after showing you the program. from chemfp import text_toolkit as T with T.read_sdf_records("ChEBI_complete.sdf.gz") as record_reader: # the comment is the 3rd line in the record = record.splitlines()[2] comment_lines = set(record.splitlines()[2] for record in record_reader) # print each comment, with a newline as a separator print(*sorted(comment_lines), sep="\n") The read_sdf_records function returns a context manager to close the file when done, so I'll use the with-statement. The context manager is also a iterator over the records in the file. For each record, I get the comment line and add it to a set. Once done, I sort the comments then print them. The splat operator * iterates over the sorted elements and turns them into positional arguments to the print function. The sep parameter separates each term by a newline (rather than a space) so one comment is on each output line. The output from this program is the same as the one-liner so I won't repeat it here. Comment counts I was curious about which comments were the most common so I modified the program to use the Counter data type. It count the number of occurrences of each unique value, and its most_common method returns the unique value and count ordered from most to least: from chemfp import text_toolkit as T from collections import Counter with T.read_sdf_records("ChEBI_complete.sdf.gz") as record_reader: comment_lines = Counter(record.splitlines()[2] for record in record_reader) for comment, count in comment_lines.most_common(): print(f"{count:8d}: {comment}") The output is: 68485: b'' 40832: b'null' 4558: b' ' 12: b' ' 4: b' ' 3: b' ' 2: b' ' 1: b' ' 1: b' ' 1: b' ' 1: b' ' 1: b'Structure generated using tools available at www.lipidmaps.org' 1: b'Mrv1722008032014042D ' That last entry, starting with Mrv1722…, is odd. It's formatted like what should have been on line 2, not line 3. And indeed, that record is missing line 2: % zgrep --before=3 --after=2 Mrv1722008032014042D ChEBI_complete.sdf.gz $$$$ Mrv1722008032014042D 6 5 0 0 0 0 999 V2000 0.0000 0.0000 0.0000 C 0 0 0 0 0 0 0 0 0 0 0 0 I was also curious about which tool put a "null" in the comment so I wrote a program which parsed the second line (which contains the program name and date). It was CDK, and all of the dates were between 2016-02-24 and 2016-02-26 or on 2017-02-23. I'll leave that implementation to the reader. It's a bit odd because git annotate cdk/io/MDLV2000Writer.java says CDK could handle that case by 2008: dc6e3a50d6 ( John May 2014-09-10 15:05:32 +0100 357) String comment = (String) container.getProperty(CDKConstants.REMARK); 7c5c872c6b ( egonw 2008-02-22 19:13:45 +0000 358) if (comment == null) comment = ""; dc6e3a50d6 ( John May 2014-09-10 15:05:32 +0100 359) if (comment.length() > 80) comment = comment.substring(0, 80); 7a2e5e230f ( egonw 2008-05-25 07:53:38 +0000 360) writer.write(comment); The ChEBI title line is not useful One thing about the ChEBI SDF distribution is that it doesn't use the title/molecule name field of the SDF record, which is the first line of the record. Using a program similar to the earlier one, I see that 64,942 records have a blank line there, 39,518 have the title null (all from CDK), plus an assortment of Structure #1, Compound 2, IUPAC names, tradenames, SMILES strings, filenames, and more. Instead, it's stored in the data block as the ChEBI ID. There's also a ChEBI Name and other fields: > <ChEBI ID> CHEBI:78425 > <ChEBI Name> albiglutide What are the ChEBI SD tags? The ChEBI ID and ChEBI Name are two of many data items which may be in a ChEBI file. What are the others? Assuming the records are clean enough, here's a one-liner using Perl which counts the number of occurrences of each unique data item tag: % gzcat ChEBI_complete.sdf.gz | perl -ne 'if (/^>.*<([^>]+)>/) {$seen{$1}++} END {foreach $key (keys %seen) {print "$seen{$key} $key\n"}}' | sort -nr 113902 Star 113902 ChEBI Name 113902 ChEBI ID 113818 Formulae 113721 PubChem Database Links 113716 Charge 112938 SMILES … 44 ArrayExpress Database Links 13 LIPID MAPS class Database Links 4 ChemIDplus Database Links 3 CiteXplore citation Links 1 PPR Links 1 FAO/WHO standards Database Links chemfp's text_toolkit module has a few functions to extract fields from an SDF record: get_sdf_tag() - get a named tag from an SDF record get_sdf_tag_pairs() - return a list of (tag name, tag value) pairs get_sdf_id() - return the first line of the SDF record I'll use get_sdf_tag_pairs() to get the list of pairs in the first record of the ChEBI file: >>> from chemfp import text_toolkit as T >>> for tag, data in T.get_sdf_tag_pairs(record): ... print(tag, data) ... b'ChEBI ID' b'CHEBI:90' b'ChEBI Name' b'(-)-epicatechin' b'Star' b'3' b'Definition' b'A catechin with (2R,3R)-configuration.' b'Secondary ChEBI ID' b'CHEBI:18484' b'InChI' b'InChI=1S/C15H14O6/c16-8-4-11(18)9-6-13(20)15(21-14(9)5-8)7-1-2-10(17)12(19)3-7/h1-5,13,15-20H,6H2/t13-,15-/m1/s1' ... b'SureChEMBL Database Links' b'SCHEMBL19412' b'UniProt Database Links' b'Q9SEV0' b'Last Modified' b'15 Feb 2018' As before, these are byte strings, not Unicode strings, so Python prints them with special escaping rules. Putting it together, here's a program which counts the number of times each unique tag is used in the ChEBI release. from chemfp import text_toolkit as T from collections import Counter tag_counts = Counter() with T.read_sdf_records("ChEBI_complete.sdf.gz") as reader: for record in reader: tag_counts.update(tag for (tag, value) in T.get_sdf_tag_pairs(record)) for tag, count in tag_counts.most_common(): print(count, tag.decode("ascii")) The output is almost the same as the one-liner; the difference is in how ties are broken when two tags have the same count. What about the performance? The one-liner with Perl takes 4.55 seconds, of which 5.55 seconds is user time and 0.26 seconds are system time. The user time is larger than the real time because on my multicore MacBook Pro the gzip decompression occurs in parallel with the perl code. The chemfp program takes 4.85 seconds, of which 4.75 are user time and 0.06 are system time. It's slightly slower than the one-liner in part because everything occurs in the same process. (Chemfp uses libz directly, for better internal performance.) Chemfp can be configured to use an external process. If I set the CHEMFP_GZIP environment to gzip then the program takes 4.57 seconds, of which 4.83 seconds are user time and 0.17 seconds are system time. This is essentially (within the measurement variability of my testing) the same as the one-liner, and with higher robustness. Get the record id for a given record Earlier we saw that one of the records has the comment Structure generated using tools available at www.lipidmaps.org. What's the associated ChEBI ID? We can parse the records to find the one with the comment, then use get_sdf_tag() to get the first value with a given tag name. While I can write it as a one-liner in the shell, I'll split it up as a more readable program that can be pasted into the Python shell or Jupyter notebook: from chemfp import text_toolkit as T for record in T.read_sdf_records("ChEBI_complete.sdf.gz"): if b"www.lipidmaps.org" in record: print(T.get_sdf_tag(record, b"ChEBI ID")) This program assumes that www.lipidmaps.org only exists once, which happens to be the case - the one line of output is CHEBI:76065. A more careful program might check if that substring is in the comment line. read_sdf_ids_and_records() An alternative is to let chemfp iterate over the pairs of (id, record) using read_sdf_ids_and_records(). By default the id is the title line, which isn't useful in the ChEBI SDF distribution. >>> from chemfp import text_toolkit as T >>> for count, (id, record) in enumerate(T.read_sdf_ids_and_records("ChEBI_complete.sdf.gz")): ... print(f"id: {id!r} starts: {record[:40]!r}") ... if count == 4: ... break ... id: '' starts: b'\n Marvin 01211310252D \n\n 22 2' id: '' starts: b'\n Marvin 02151210452D \n\n 11 1' id: '' starts: b'\n Mrv0541 12031312382D \n\n 10 ' id: '' starts: b'\n Marvin 10251009462D \n\n 24 2' id: '' starts: b'\n Marvin 11020709032D \n\n 10 1' Instead, ask it to get the id from the data item with the tag name ChEBI ID: >>> for count, (id, record) in enumerate(T.read_sdf_ids_and_records("ChEBI_complete.sdf.gz", id_tag="ChEBI ID")): ... print(f"id: {id!r} starts: {record[:40]!r}") ... if count == 4: ... break ... id: 'CHEBI:90' starts: b'\n Marvin 01211310252D \n\n 22 2' id: 'CHEBI:165' starts: b'\n Marvin 02151210452D \n\n 11 1' id: 'CHEBI:598' starts: b'\n Mrv0541 12031312382D \n\n 10 ' id: 'CHEBI:776' starts: b'\n Marvin 10251009462D \n\n 24 2' id: 'CHEBI:943' starts: b'\n Marvin 11020709032D \n\n 10 1' This simplifies the search program to: >>> from chemfp import text_toolkit as T >>> for (id, record) in T.read_sdf_ids_and_records("ChEBI_complete.sdf.gz", id_tag="ChEBI ID"): ... if b"www.lipidmaps.org" in record: ... print(id) ... CHEBI:76065 ChEBI ID as a function of date The second line of the SDF record may contains a timestamp, though in practice it can be empty or be incorrectly formatted. I'm curious to see how the ChEBI ID changes as a function of date. I presume it's roughly linear. I started Jypter and pasted the following in the first cell: import datetime from chemfp import text_toolkit as T timestamps = [] chebi_nums = [] num_records = num_missing_timestamp = num_bad_timestamps = 0 for chebi_id, record in T.read_sdf_ids_and_records("ChEBI_complete.sdf.gz", id_tag="ChEBI ID"): num_records += 1 assert chebi_id.startswith("CHEBI:"), chebi_id chebi_num = int(chebi_id[6:]) lines = record.splitlines() timestamp_str = lines[1][10:20] if not timestamp_str: num_missing_timestamp += 1 continue try: timestamp = datetime.datetime.strptime(timestamp_str.decode("ascii"), "%m%d%y%H%M") except ValueError: #print(f"Cannot parse timestamp for {chebi_id}: {timestamp_str}") num_bad_timestamps += 1 chebi_nums.append(chebi_num) timestamps.append(timestamp) # The f'{expr=}' option was added in Python 3.8 # https://docs.python.org/3/whatsnew/3.8.html#f-strings-support-for-self-documenting-expressions-and-debugging print(f"{num_records=} {num_missing_timestamp=} {num_bad_timestamps=}") The output was: num_records=113902 num_missing_timestamp=4855 num_bad_timestamps=1718 Then in the next cell, plot the ids as a function of time: %matplotlib inline import matplotlib.pyplot as plt plt.style.use('seaborn-whitegrid') plt.xlabel("date") plt.ylabel("ChEBI ID") plt.plot(timestamps, chebi_nums, 'o', color='black') # plt.savefig("ChEBI_ids_over_time.png") The resulting scatter plot surprised me - I wonder what happened around 2008 and 2011 to have those spikes. But I'll leave it as an idle curiousity. Atom and bond count distributions If you know the chemistry is correct then it can be faster to process an SDF as text rather than use a chemically-aware toolkit. OEChem is the fastest chemistry toolkit I use; it takes only 17 seconds to parse the 113,902 ChEBI records. However, suppose you want to get a distribution of the heavy atom and bond counts for molecules with at most 100 atoms or 100 bonds. That information is available (almost) from the counts line on the fourth line and can be extracted with the following in about 3.5 seconds: from chemfp import text_toolkit as T atom_counts = [] bond_counts = [] for record in T.read_sdf_records("ChEBI_complete.sdf.gz"): lines = record.splitlines() counts_line = lines[3] num_atoms = int(counts_line[:3]) num_bonds = int(counts_line[3:6]) num_explicit_hydrogens= sum(1 for line in lines[5:5+num_atoms] if line[31:34].strip() == b'H') num_atoms -= num_explicit_hydrogens num_bonds -= num_explicit_hydrogens if num_atoms > 100 or num_bonds > 100: continue atom_counts.append(num_atoms) bond_counts.append(num_bonds) That num_explicit_hydrogens code handles the almost case where there are explicit hydrogens in the atom block, assuming all hydrogens have one and only one bond! It iterates through the atom block lines, extracts the element symbol (the [31:34]), removes any whitespace, and checks if the result is H for hydrogen. Since the record is a byte string, and I use byte string operations, I need to test the result against the byte string b'H'. Histogram of atom and bond counts I visualized the results in a Jupyter notebook using the following: %matplotlib inline import matplotlib.pyplot as plt plt.style.use('seaborn-whitegrid') plt.suptitle("ChEBI records with at most\n100 heavy atoms or bonds") plt.subplot(1, 2, 1) plt.ylabel("number of records") plt.xlabel("atom counts") NA = max(atom_counts) plt.hist(atom_counts, range=(0, NA), bins=NA) plt.subplot(1, 2, 2) plt.xlabel("bond counts") NB = max(bond_counts) plt.hist(bond_counts, range=(0, NB), bins=NB) #plt.savefig("ChEBI_atom_bond_counts_histogram.png") Giving the following plot: Warning! Beware! This is getting perilously close to writing your own cheminformatics toolkit! Always ask yourself if the extra performance is worth things like accidentally and silently failing on V3000 records, or allowing invalid chemistry, or including salts, or the other things that a full-fledged toolkit can handle.

The Joomla Project is pleased to announce the availability of the Joomla 4.0 Beta 4 release, and the second Alpha of Joomla 3.10.

With Joomla 4.0 beta being released a few weeks ago, we enter into a phase of stabilization. Joomla! 4.0 is feature complete, that means, no new features are going to be added to Joomla 4.0. The focus is on fixing the last bugs to get Joomla! 4.0 out as soon as possible. But what will happen until the release and afterwards? Obviously we don’t want to stop new feature development, which is why we would like to refine our development strategy for upcoming versions. Whenever we start the work on a new minor version, we plan to define the subsequent two minor releases This results in a more reliable release cycle and a more consistent road map.

Choopa.com has now had the most reliable hosting company site three times in 2020. The company provides a range of services including cloud hosting, dedicated servers, colocation and managed services from four locations across the US, Europe and Asia. Swishmail appeared in second place, also responding to all of Netcraft's requests in August. Swishmail provides business email services alongside hosting solutions. Rackspace, Bigstep and EveryCity appear in third, fourth and fifth places. Rackspace had the second fastest average connection time and has appeared in the top 10 six times in 2020. Bigstep offers "bare metal" cloud hosting to provide the flexibility of cloud hosting but without the associated overhead and performance reductions of virtualization. EveryCity has appeared in the top 10 seven times in 2020 and is the only site that uses SmartOS.

The Netcraft Browser Extension now offers credential leak detection for extra protection against shopping site skimmers. With brick-and-mortar shops around the world closed due to COVID-19, consumers turned to online businesses to fulfil their shopping needs. According to Adobe’s Digital Economy Index report, US online spending in June was $73 billion, up 76% from $42 billion last year. Even with restrictions lifted, research commissioned by Visa suggests that 74% of Britons who shopped online more often during the lockdown will continue to do so. Now more than ever it is important to protect against JavaScript skimmers. These are snippets of malicious code which criminals upload to compromised shops. Unbeknownst to the store owner or the user, they transmit entered card details directly to the criminal. Unlike scams such as phishing, which can often be avoided by a vigilant internet user, skimmers are invisible to the human eye without a tool such as the Netcraft Extension to expose them. Netcraft currently blocks over 6,000 shopping sites which contain skimmers, and even large companies such as British Airways, Ticketmaster and Puma have fallen prey to these attacks in the past. The Netcraft Extension identifying and blocking a skimmer on an online shop When you visit a shopping site, the Netcraft extension will evaluate all requests made by the web page. If a request is found to be sending credentials to a different domain, the extension will block the request to prevent your data from being stolen. A block screen will notify you about the request and provide information about the malicious behaviour that was detected. Only card number leaks are currently blocked, but other types of credentials may be enabled in future updates. For example, if you check out using your credit card on exampleshoppingsite.com but your card details are sent to examplebadsite.com, the extension will block the request. This checking is done locally and securely in your browser – no sensitive information is sent to Netcraft. The extension will also block pages which make requests to malicious domains that are part of JavaScript attacks. In addition to shopping site skimmers, the Netcraft Extension also protects against other malicious JavaScript, phishing and fake shops, including those related to coronavirus. The extension is available for Chrome, Firefox, Opera and the new Microsoft Edge based on Chromium. If you already have the Netcraft Extension installed, your browser will update it automatically.

In the August 2020 survey we received responses from 1,230,576,586 sites across 261,821,287 unique domains and 10,349,486 web-facing computers. This represents a loss of 3.65 million sites, but a gain of 1.16 million domains and 128,000 computers. The number of web-facing computers using nginx increased by 83,000 this month, which means that - for the first time - nginx is in use by more web-facing computers than any other web server, including Apache. This is another milestone for nginx, and reflects its impressive growth in recent years. Apache still serves more active sites than nginx, and a greater proportion of the top million busiest sites, but this month its decline in these metrics continued. One year ago, among the top million busiest sites, nginx trailed Apache’s market share by 6 percentage points. nginx has since halved this gap, and is now less than 3 percentage points behind. If the current trend continues, it won’t be long before nginx overtakes Apache in this area too. As well as a marked decrease in total sites this month of 22.14 million (-15.8%), Microsoft also suffered in other metrics this month. The number of domains served using Microsoft software dropped by 8.27 million (-18.4%), and 19,000 fewer web-facing computers (-1.2%) are running Microsoft web servers. Microsoft also lost 633,000 active sites (-7.3%). New vendor releases Apache released three new versions of httpd this month. Version 2.4.44 fixed several bugs, version 2.4.45 dropped support for the abandoned HTTP2 Cache Digests proposal, and version 2.4.46 fixed three security vulnerabilities. This month nginx released updates for three of its products. nginx 19.1.2 mainline was released on 11 August with a few minor optimizations and several bugfixes. On the same day, njs 0.4.3 was released, adding support for the querystring module.

Netcraft has released a new version of its phishing and cybercrime protection app for iOS. The app protects users around the world from online threats including phishing, JavaScript skimmers, fake shops, and coronavirus scams. The Netcraft app is available for download today on iOS, Android, and Amazon devices: Our iOS app protects against online threats, with new attacks blocked within 15 minutes of being identified as fraudulent by Netcraft. It offers a 28-day free trial of all features, after which a monthly or annual subscription can be purchased for $1.99 or $9.99 (£1.99 or £9.99). You can use the app without a subscription to report suspicious sites to Netcraft with just a few taps, and automatically report URLs in SMS and iMessages from unknown senders. Wherever you are, the app defends against phishing attacks targeting regional services such as governments and banks. In addition, it protects users against other types of online threat such as JavaScript skimmers on eCommerce sites, fake shops imitating well-known brands, new threats such as coronavirus scams, and attacks targeting global entities – such as cloud services, financial institutions, and social media.

In the July 2020 survey we received responses from 1,234,228,567 sites across 260,658,118 unique domains and 10,221,919 web-facing computers. This represents a gain of 9.47 million sites and 180,000 computers, but a loss of 1.75 million domains. Most of the major server vendors saw gains in total sites this month: Apache gained 9.8 million sites after a loss of roughly the same size last month, while Microsoft and nginx gained 5.4 million and 2.5 million sites respectively. LiteSpeed continued to see strong growth, gaining 1.95 million new sites this month. Although it makes up 2.17% of the market, this represents strong growth from 1.62% at the start of the year. nginx showed the highest growth in terms of domains, gaining 200,000. Losses of 1.1 million domains for Microsoft and 998,000 for Apache have further boosted nginx’s lead in this metric, and it now stands around 30 million domains ahead with a 29.8% (+0.27 pp) market share. nginx also showed the highest growth in web-facing computers, with an increase of 97,000 taking its total to 3.5 million and leaving it just 9,000 computers (0.09 pp of market share) shy of Apache, the current leader. Apache has consistently had the highest number of web-facing computers since Netcraft began tracking the metric in 2007, but has slowly been losing market share – primarily to nginx. Microsoft trails in third position with a total of 1.6 million web-facing computers, around half that of nginx and Apache. New vendor releases LiteSpeed announced the first release candidate of LiteSpeed Web Server 6.0 on 17 July. This release brings several major new features such as support for conditionals in Apache configuration files, asynchronous execution of the mod_security Web Application Firewall, and sandboxed execution environments for PHP and CGI scripts. It also adds support for the latest HTTP/3 specification, draft 29. LiteSpeed has historically been fast to adopt new draft versions of HTTP/2 and HTTP/3, often implementing support within a month of a new draft’s release. nginx 1.19.1 mainline was announced on 7 July with a few minor changes and bugfixes – mainline being the release stream which receives new feature updates. Alongside this, nginx released version 0.4.2 of njs, a custom subset of JavaScript which allows nginx’s functionality to be extended. This release adds new regular expression and filesystem methods to the language, in addition to bugfixes.

More than two thousand sites using Extended Validation certificates stopped working this weekend and remain inaccessible today (Monday), including those run by banks, governments, and online shops. The EV certificates used by these sites were revoked on Saturday, and have yet to be replaced. Most visitors using modern web browsers are completely locked out: this certificate error cannot be bypassed in Chrome, Firefox, Safari, or Microsoft Edge. Chrome’s unbypassable revoked certificate interstitial on online.anz.com. ANZ is one of the"big four" Australian banks. Last week, DigiCert disclosed a reporting discrepancy in its audit for EV certificates. As part of its response, DigiCert committed to revoking the certificates, which it intends to complete over the coming weeks. Only a subset of DigiCert’s EV certificates are affected: in the July SSL Server Survey, Netcraft found 17,200 EV certificates in active use on port 443 that are due to be revoked. The first batch of revocations happened this weekend. While most of the certificates revoked on Saturday 11th July have been correctly replaced and reinstalled, many have not. On Monday morning, Netcraft found 3,800 sites still using EV certificates issued by the affected sub-CAs. Of these 3,800, more than 2,300 were still using a revoked EV certificate, completely disabling the sites for users in modern browsers, which handle EV revocation more robustly than other types of certificate. The remainder are yet to be revoked. Many organisations appear to have been caught unawares, continuing to use revoked EV certificates, including The State Bank of India, Rackspace, Authorize.net, ANZ Bank, and Telegram. Authorize.net using a revoked EV certificate The New Zealand government using a revoked EV certificate Wirecard, the beleaguered German payment processor, briefly had its main site, www.wirecard.com, displaying a certificate warning early on Monday, but the certificate has since been replaced with a working non-EV certificate. There are still a number of Wirecard domains with revoked certificate warnings.
